The technique, using gold nanoparticles, is the first to deploy metal nanoparticles as agents to enhance X-ray scattering of image tumor-like masses. Results are published in in the American Chemical Society journal Nano Letters.
Hepatocellular carcinoma is the most common cancer to strike the liver. More than 500,000 people worldwide, concentrated in sub-Saharan Africa and Southeast Asia, are diagnosed with it yearly. Most of those afflicted die within six months.
A big obstacle to treatment of liver cancer is the lack of early diagnosis. Current techniques, including ultrasound, CT and MRI scans, spot tumors only when they have grown to about 5 centimeters in diameter. By that time, the cancer is especially aggressive, resisting chemotherapy and difficult to remove surgically.
Now a research team led by Brown University reports some promising results for earlier diagnosis. In lab tests, the team used gold nanoparticles ringed by a charged polymer coating and an X-ray scatter imaging technique to spot tumor-like masses as small as 5 millimeters. The approach, detailed in the <a href="http://pubs.acs.org/doi/abs/10.1021/nl200858y?journalCode=nalefd">American Chemical Society journal Nano Letters</a>, marks the first time that metal nanoparticles have been used as agents to enhance X-ray scattering signals to image tumor-like masses.

“What we’re doing is not a screening method,” said Christoph Rose-Petruck, professor of chemistry at Brown University and corresponding author on the paper. “But in a routine exam, with people who have risk factors, such as certain types of hepatitis, we can use this technique to see a tumor that is just a few millimeters in diameter, which, in terms of size, is a factor of 10 smaller.”
The team took gold nanoparticles of 10 and 50 nanometers in diameter and ringed them with a pair of 1-nanometer polyelectrolyte coatings. The coating gave the nanoparticles a charge, which increased the chances that they would be engulfed by the cancerous cells. Once engulfed, the team used X-ray scatter imaging to detect the gold nanoparticles within the malignant cells. In lab tests, the nontoxic gold nanoparticles made up just 0.0006 percent of the cell’s volume, yet the nanoparticles had enough critical mass to be detected by the X-ray scatter imaging device.
“We have shown that even with these small numbers, we can distinguish these [tumor] cells,” Rose-Petruck said.
The next step for the researchers is on the clinical side. Beginning this summer, the group will attach a cancer-targeting antibody to the nanoparticle vehicle to search for liver tumors in mice. The antibody that will be used was developed by Jack Wands, director of the Liver Research Center at Rhode Island Hospital and professor of medical science at the Warren Alpert Medical School of Brown University.
“We have developed a monoclonal antibody that targets a cell surface protein highly expressed on liver cancer cells,” Wands said. “We plan to couple the antibody to the gold nanoparticles in an attempt to detect the growth of early tumors in the liver by X-ray imaging.”
The researchers say the X-ray scatter imaging method could be used to detect nanoparticle assemblies in other organs. “The idea should be that if you can figure out to get that [nanoparticle] to specific sites in the body, you can figure out how to image it,” said Danielle Rand, a second-year graduate student in chemistry and the first author on the paper.
Contributing authors include Yanan Liu from Brown, Wands, Zoltan Derdak and Vivian Ortiz from the Liver Research Center, and Milan Taticek at the Czech Technical University in Prague.
The National Institutes of Health and the U.S. Department of Energy funded the research. Rand’s work was supported by the U.S. Department of Education through the Graduate Assistance in Areas of National Need (GAANN) fellowship, administered by the Institute for Molecular and Nanoscale Innovation at Brown.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-747551689720815977?l=smalltechtalk.blogspot.com' alt='' /></div>tag:blogger.com,1999:blog-6331358152894046568.post-7475516897208159772011-06-22T15:55:00.000Z2011-12-16T14:50:25.885ZAnnouncing New Online Seminar: Understanding Nanotechnology Safetynoemail@noemail.orgPete SingerRegistration is now open for an <a href="http://downloads.pennnet.com/digitalmedia/st/stwebcast2.html">online seminar on nanotechnology safety.</a> This seminar is of interest to anyone concerned about the potential health hazards of exposure to nanoengineered materials.

I am overwhelmed with curiousity. Will someone please contact Gannady and report back to me!?<br><br>
"Dear ladies and gentlemen,
I offer for purchase made by me 254 inventions in the sphere of nanotechnologies with the help of the single-purpose heuristic method aimed at inventions making in the sphere of nanotechnologies.
Already Socrates defined the heuristic method as a method creating new systems. Currently more than 200 heuristic methods are created for technical systems development. In this country “Invention Algorithm” developed by G.S. Altschuller is the most common. On the basis of this method in the USA a well-reputed program “Invention Machine” was developed and is distributed by the Invention Machine Corporation.
But all these developments fall into the wide area of general engineering and are of little use for nanotechnologies development.
There didn’t yet exist a single-purpose heuristic method. The author studied heuristic methods for more than 20 years and he has managed to develop a powerful heuristic method for inventions in the nanotechnology sphere making. With the help of this method more than 250 inventions in the sphere of nanotechnologies were made. The inventions appeared to be very powerful and they can result in a very great economic effect.
The author wasn’t able to patent the inventions himself and to test them experimentally. Your company can easily make this job.
I shall try to describe my work in more detail. I was engaged in heurisms more than 20 years and I had a desire to create a heurism for area nanotechnology. It was possible to me. The heurism has turned out very powerful and effective. By means of these method I managed to create 254 inventions in the field of nanotechnology. The created inventions concern to various areas nanotechnology
and in them various physical effects are used. The greatest attention has been given by me to nanotubes, a matter from nanotubes, updatings of these objects and to creation new nanomaterials from various nanopowders and their mixes by means of compacting. 3 demonstration, insignificant inventions created by algorithm I apply.

It's been a rough year as everyone knows so many of the "big" companies were either not exhibiting or camped out in local hotels. However, almost everyone I talked to was positive about the future of the semiconductor industry and most said they saw "lights on the horizon" or some optimistic words to that effect. A little early to celebrate, but the semiconductor industry turned the corner back in January or February this year, and it's certain the equipment and materials industry will follow. <br><br>
Aside from the fallout of a devastating recession (good luck with the recovery as Newseek notes in the latest issue), I think there's also some alarm among the exhibiting (and advertising) community that the semiconductor industry is "closed" in that there will not be any new entrants, no new companies popping up to manufacture microprocessors or memories. The same is true albeit to a lesser extent on the equipment and materials side. Process technology has been commoditized (not a real word but you know what I mean). Even if you were to build a better mousetrap, it's quite a long uphill battle to get the likes of Intel to consider putting it through all the qualifications necessary to put it into volume production, and convince them that you'll be able to support it on a worldwide basis with field engineers, spare parts, etc. In short, companies think they know all their customers -- there are no surprise $5 billion fabs (and if there were they'd be in China) -- so what's the point of spending big bucks on a tradeshow booth.
That's true to some extent but it's a bit early to be hoisting the white flag of surrender. The semiconductor industry is still massive and evolving and is still the "oil of the IT industry" as someone once said. "More than Moore" is just a catchphrase at the moment but I think that's where the future lies. Higher levels of integration made possible through 3D chip stacking, and other advanced types of packaging, will be where the action is. Sure, we'll still see shrinking dimensions (is it EUV or imprint?? -- expect the status quo for years imho) and probably lots more talk on 450 mm as the economy improves. BUT there will be new players, new opportunities, lots of room for strong growth which all gets back to the critical importance of a show such as SEMICON West. It will return with gusto, we'll be talking about cool things that have yet to be dreamed up and it will remain a vibrant and dynamic industry. Why? People want to watch movies on their cell phones while sitting on a smart toilet that analyzes how close they are getting to death from the inevitable cancer, heart attack, diabetes, or just old age. The best presentation at SEMICON West? From Proteus on Intelligent Medicine: Helping to Solve the Healthcare Crisis with MEMS and ICs. "First there was the Apple on your desktop, next there was a Blackberry on your belt. Now there will be a raisin inside you," said Andrew Thompson, president and CEO, co-founder, <a href="http://www.proteusbiomed.com"> Proteus Biomedical.</a>
Speaking of presentations, huge kudos to the staff of SEMI who did an excellent job of lining up great speakers for a variety of tech sessions running throughout the three days of the show. They were particularly speedy in getting the presentations posted on-line. That's a ton of work that sometimes goes unrecognized. I'd link to them here but I they they should be easy enough to find on the SEMI site. You have Google, don't you? :-)

I started this blog last year, then Howard – one of the original editors of Small Times -- took it over for awhile. Now, like tag team wrestling, I’m back in the ring. Howard is “pursuing other interests” as they say. He says in his last <a href="http://nanobot.blogspot.com/">NanoBot blog</a> that he’s giving up on social media, but I’m hopeful we’ll see him again.<br>
This week I’m spooling up for Semicon – ya know, like the Gatling Gun has to spool up before you can fire it (blam blam blam). Next week’s Semicon West will be a busy one for our PennWell team, with our colleagues from SST, Photovoltaics World, The ConFab, Advanced Packaging, SMT, Small Times, Laser Focus World and Renewable Energy World out in force. We have a boatload of video interviews lined up, plus podcasts and yes I’ll be “tweeting”. Sign up for <a href="http://twitter.com/PetesTweetsPW"> Pete's Tweets</a>. I’m also moderating a couple sessions – one Tuesday morning on <a href="http://www.semiconwest.org/ProgramsandEvents/ExtremeElectronics/CTR_029515?snc=15601">Opportunities in MEMS</a> and another on <a href="http://www.semiconwest.org/ProgramsandEvents/ctr_028974?parent=yes&parentId=5">thin film PV</a> Thursday morning. Don’t miss ?em! Standing room only!
Last year, the three big things that had people talking were 1) the state of the industry, 2) the co-located InterSolar show, and 3) 450 mm (or 45 cm as was noted at the SEMI press conference). This year, #1 and #2 are sure to be the hot topics – 45 cm not so much.
At the time, SEMI released <a href="http://wps2a.semi.org/wps/portal/_pagr/103/_pa.103/248?dFormat=application/msword&docName=P044189 ">a mid-year consensus forecast </a> for the chip equipment industry that indicates that, following a six percent market growth in 2007, the equipment market will decline 20% in 2008, but will experience a rebound with annual growth of 13 percent and six percent in 2009 and 2010, respectively. That was wishful thinking, but good signs abound that the recovery has begun. <a href="http://www.solid-state.com/display_article/364676/5/none/none/TCHNE/Analyst:-Buckle-up-for-double-digit-growth-again ">Bill McClean is still calling for a couple of boom years</a>; he just moved the proverbial hockey stick out to 2010, 2011.
The InterSolar last year had 209 exhibitors, 48 of which are SEMI members. SEMI said there were 251 total Semicon West exhibitors with PV product offerings. The InterSolar show had some good traffic, but a fair amount of the exhibitors were fairly low-tech, including such things as roof mounting brackets. More of the same this year? You bet. I know it’s bigger but don’t have the stats in front of me. Will we see more traditional SEMI exhibitors setting up camp at InterSolar? I expect some, but not a mass exodus.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-6798465021992967428?l=smalltechtalk.blogspot.com' alt='' /></div>tag:blogger.com,1999:blog-6331358152894046568.post-67984650219929674282009-07-07T21:07:00.000Z2011-12-16T14:50:27.257ZMEMS-enabled PUMA: Look at the firstname.lastname@example.orgHoward Lovy<p>I feel like it is 1909, rather than 2009, as I hear a derisive chorus of "get a horse" from much of the media mocking the MEMS-enabled <a href="http://www.segway.com/blog/20090406introducing-project-puma-329.html">PUMA prototype electric vehicle</a> from General Motors and Segway.</p>
<p>An automotive correspondent from Newsweek wrote on Twitter that he "thinks the GM Segway vehicle is a farce." And even the editor of Wired.com, who should know how to spot possibilities better than other journalists, Tweeted: "NOte to GM: car with no door = FAIL."</p>
<p>It is likely the PUMA uses the same MEMS gyro/accelerometer cluster as the Segway, which last I heard was supplied by the UK MEMS company Silicon Sensing Systems.</p>
<p>The mockery doesn't say much for the vision of many in my profession ... again. It seems like members of the news media -- the survivors who are left employed, anyway -- would have learned from the recent past to recognize the early stages of something that could potentially change everything. But, even now as newspapers close and bleed jobs, many continue to lovingly clutch onto their dinosaurs, failing to look up to see the meteor looming in the sky.</p>
<p>A century ago, those funny, noisy, slow horseless carriages seemed as much a ridiculous joke as perhaps the rickety-looking GM/Segway electric carriage might seem now. But, as most Small Times readers know, the thing to look for is not always right in front of you. We cover, for the most part, enabling technologies -- the invisible "stuff" on the inside that enhances existing products or enables new ones.</p>
<p>Like the Segway, itself -- also a subject of tech-writer derision when first unveiled -- entrepreneurs look at the capabilities of a prototype like the PUMA and see how the enabling technologies can be used to fit their own visions of how a "smart" vehicle should run.</p>
<p>Writers based in New York, or Detroit, at times fail to realize that the world does not necessarily look like their own familiar surroundings. Newly prosperous residents of jam-packed cities in Asia, for example, are all looking to become "American-style" consumers. But the level of traffic congestion that would suggest is not possible if we are truly going to reduce greenhouse gases.</p>
<p>Let 'em walk, ride bikes or take buses? Easy for the current "haves" to say.</p>
<p>No, I look at the PUMA, and see possibilities. And, I suspect, so do the engineers, scientists and entrepreneurs who read these pages.</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-237846486043198699?l=smalltechtalk.blogspot.com' alt='' /></div>http://localhost:4503/content/eiq-2/en/blogs/small-talk-tech/2009/04/mems-enabled-puma-look-at-the-possibilities.html2009-04-08T18:00:00.000Z2011-10-23T02:42:04.539ZNanobusiness is about business, yes; but it's also about email@example.comHoward Lovy<p>Beware of nanotech "news stories" that declare that the scientific breakthrough of the day "may someday lead to ... " or "will be on the market in the next 5-10 years ..." Odds are, it's great science, but its business application is miles away from port.</p>
<p>And that's fine. I love to follow science news from the world's top universities and labs. I read tons of it every day. Not much of it, however, makes it onto the pages of Small Times or is posted online here.</p>
<p>There are lots of other online nanotech portals for that.</p>
<p>Back in 2001, when I was among the founding editors of Small Times, the mantra we began as one of the first to cover nanotech from a business perspective was "Is it us?" I would ask my group of scattered of freelance correspondents -- sometimes to their annoyance -- what about the story they were pitching to me makes it rise above the level of lab breakthrough and into the realm of a business story.</p>
<p>About eight years later now, it's a lot easier to tell the difference as more of the science experiments we covered in the beginning are being commercialized. </p>
<p>It has gotten to the point now where Scott E. Rickert, chief executive of Nanofilm Ltd., has gone as far as to declare that "the era of endless exploration is over -- at least as long as the economy stumbles." <a href="http://www.industryweek.com/articles/taking_the_nanopulse_--_no_more_science_experiments_18642.aspx?Page=2&SectionID=2?ShowAll=1" target="new">Writing in IndustryWeek</a>, Rickert expresses his impatience now with nanotech information that is not directly related to business.</p>
<p>"Nanobusiness is business. Period. First, last, always," Rickert declares.</p>
<p>And, of course, he names Small Times as one of the few publications he turns to when he wants to read about trends in nanobusiness as opposed to nanoscience.</p>
<p>I thank Scott for the "shout-out." We've been trying for years to make Small Times different than your average sci/tech publication. And, of course, your contribution helps, too. If you are commercializing nanotech, or are about to, <a href="mailto:firstname.lastname@example.org">please contact me</a> and let's generate some coverage.</p>
<p>But, as those who know me from some of <a href="http://nanobot.blogspot.com" target="new">my other projects</a> have seen, I do not always believe in hard-and-fast rules. Sometimes, it is just plain cool to read about the future possibilities of where today's nanobusiness might take us.</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-1096444027321202375?l=smalltechtalk.blogspot.com' alt='' /></div>http://localhost:4503/content/eiq-2/en/blogs/small-talk-tech/2009/03/nanobusiness-is-about-business-yes-but-it-s-also-about-possibilities.html2009-03-23T07:10:00.000Z2011-10-23T02:42:08.408ZReporting live from the NanoTwitterVersenoemail@noemail.orgPete Singer<p>Yesterday's headline in The UK's Guardian blared "<a href="http://www.guardian.co.uk/technology/2009/mar/05/micro-darpa-microchips" target="new">Nanotechnology goes to war</a>."</p>
<p>The story is about how the Pentagon is using small tech for improved sensors, robotics and other applications. The only trouble is that very little of the information there is new and, aside from the headline, the article contains no examples of actual nanotechnology. Much of it was about labs-on-a-chip, MEMS and other technologies you read about on this site every day.</p>
<p>But, in an age where print journalism is dying and online journalism is still trying to define itself, the Guardian article is not the last word. It is, in fact, only the beginning of the conversation about the news.</p>
<p>Ideas today are circulating in 140-word, self-contained blocks -- mostly via social networking sites like Facebook and Twitter.</p>
<p>Yesterday's Guardian piece was just a few hour old, when the NanoTwitterVerse chimed in -- the opening shot coming from British nanopundit Tim Harper, who <a href="http://twitter.com/tim_harper/status/1282631926" target="new">Tweeted</a> that the "nano" piece was not about nano. </p>
<p>Harper was answered by prolific Twitterer Andrew Maynard, chief science adviser for the Project on Emerging Nanotechnologies in Washington. On Twitter, he is known by the name of his blog: 2020science. His <a href="http://twitter.com/2020science/status/1283103359" target="new">response to Harper:</a> "Hate to say it, but nano-promoters have been piggybacking on MEMS for some time - not surprising that journalists mix'n'match!"</p>
<p><a href="http://twitter.com/tim_harper/status/1283180636" target="new">Harper:</a> Thought it was the other way around -MEMS have been trying to get their claws into sexy nano funding 4 years</p>
<p><a href="http://twitter.com/2020science/status/1283281731" target="new">2020science:</a> think you're probably right - from a distance, thinks get a little blurry!</p>
<p>The exchange was important for a few reasons. First, despite the appearance of a cozy two-way conversation, it was read by their thousands of Twitter "followers," or other people on Twitter who are interested in their updates. Any one of them can "retweet" the conversation and the word can spread virally. It also was a necessary counterpoint from two nanotech "insiders" to the viral spread of the story outside the world of nanotech experts.</p>
<p>The Guardian story was <a href="http://digg.com/gaming_news/Pentagon_Nanotechnology_goes_to_war" target="new">also posted on the news networking site Digg.com,</a> with readers' comments indicating that they couldn't care less about the accuracy of the headline, but used it as a launching point for their own personal fears or hopes for however they define "nanotechnology."</p>
<p>Through Twitter and Digg, what we're still talking about here is not even the "blogosphere," but a new layer that has emerged -- quick, opinionated, emotional, probably unfair, but increasingly responsible for what becomes widely circulated and commented upon by the public at large.</p>
<p>Comparitively, blogs are practically "the establishment" now. And they're so damn wordy. (Looking back at <a href="http://nanobot.blogspot.com/2003_07_01_archive.html" target="new">my first month of blogging back in 2003</a>, it looked like I was going for "War and Peace" with each long-winded post).</p>
<p>For the Guardian story, Harper saw something deeper in the misuse of "nanotechnology" in the headline and needed the longer blog format to express them.</p>
<p>"There's no space for more considered opinions on Twitter so you need to combine it with other media," Harper told me in a brief interview I conducted with him yesterday on Twitter ("Twitterview"?)</p>
<p>What resulted was a post on his blog called "<a href="http://cientifica.eu/blog/?p=979" target="new">politicizing nanotechnology</a>," in which he discussed how nanotech is viewed through the prism of political agendas.</p>
<p>In comparison to his "Tweets," Harper's blog posts require an attention span and the ability to follow more than one simultaneous theme. That's not to knock Twitter at all, though. Sifting through dozens of Tweets every day -- or even hundreds, depending on how much time you have during the day -- on a nanotech theme, you can get differering views on the same topic.</p>
<p>Harper's Tweets are enjoyable because, aside from his usual rants against the "nanobot crowd" he'll slip in a few personal tidbits -- like how he sat near Jacques Chirac at a Paris restaurant. I can picture him sitting there, noticing Chirac and the first thing he thinks of is Twittering the news.</p>
<p>The largest criticism I have of the NanoTwitterVerse is that it at times can be a feedback loop -- the usual suspects talking inside baseball to one another, or "retweeting" one another to the point where only one point of view bounces around an echo chamber. That will change as more nanotech voices join the conversation.</p>
<p>Another notable nano voice on Twitter is <a href="http://twitter.com/Kulinowski" target="new">Kristen Kulinowski</a>, executive director for policy at Rice University's Center for Biological and Environmental Nanotechnology. She <a href="http://twitter.com/Kulinowski/status/1202923670" target="new">recently Tweeted</a> the Rice Alliance Nanotechnology and Sustainability Venture Forum, giving live, as-it-happens updates.</p>
<p>The live events are enjoyable, although sometimes a bit cryptic, since 140 words a pop seems limiting for an on-the-spot reporter. Maynard does it, too, and knows <a href="http://twitter.com/2020science/statuses/1254596930" target="new">when to Tweet</a> (Congressional hearing on the Toxic Substances Control Act) and when <a href="http://twitter.com/2020science/status/1247259072" target="new">not to Tweet</a> (NNI exposure assessment workshop).</p>
<p>Like blogging about five years ago, Twitter is something that you either "get," or you do not. A great many believe that, in the words of Houston Chronicle Science Writer (and prolific Twitterer) <a href="http://twitter.com/chronsciguy/status/1284368902" target="new">Eric Berger</a>, "it was mostly people posting pics of their breakfast."</p>
<p>Well, yes, <a href="http://twitter.com/hlovy/status/1284437239" target="new">there's that, too</a>.
<p>But amid some of the silliness, there's substance in Twitter when taken as a whole. Does it stand alone as a source of news? Of course not. Does it give more people a chance to participate in the discussion about the news? Maybe it will, someday, but for now it is another way to interact with the world by telling it to others from your own perspective -- a kind of Seussian, "we are here" for journalists, too, who sometimes forget about all those Whos down in Whoville.</p>
<p>Oh, and speaking of kids' stuff, have you heard about that "nanosong" video that explains nanotech with music and puppets? It was <a href="http://twitter.com/2020science/status/1253304049" target="new">first spread virally via the Twitterverse.</a></p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-7879152266708331159?l=smalltechtalk.blogspot.com' alt='' /></div>tag:blogger.com,1999:blog-6331358152894046568.post-78791522667083311592009-03-06T11:06:00.000Z2011-10-23T02:42:07.987ZNew nano rules may leave Canada out in the email@example.comPete Singer<p>If you ask Canadian entrepreneur Neil Gordon about new rules coming next month requiring companies to detail their use of engineered nanomaterials, he'll tell you it's just another example of his government placing artificial constraints on nanotech commercialization.</p>
<p>That's why Gordon is now the ex-president of the now-defunct Canadian NanoBusiness Alliance.</p>
<p>"If Canada is becoming the first government in the world to require companies to provide information about their use of 'potentially' harmful nanomaterials in products, then there is another reason for entrepreneurs to avoid commercializing nanotechnology products in Canada," said Gordon, who is now president and CEO of <a href="http://www.earlywarninginc.com/" target="new">Early Warning Inc.</a>, which is commercializing a nanotech-based biosensor.</p>
<p>But ask science adviser Andrew Maynard about Canada's first-in-the-world nanotech regulations, and he'll tell you how they are exactly what is needed now -- before too many companies use nanotechnology in their products. Maynard advises the <a href="http://www.nanotechproject.org/" target="new">Project on Emerging Nanotechnologies</a> (PEN) in Washington, which focuses on the environmental, health and ethical implications of nanotechnology.</p>
<p>The rules are needed, he said, even though available toxicity information on some engineered nanomaterials is "patchy."</p>
<p>"But even patchy information is going to be more helpful to developing informed future regulations, than no information," Maynard said.</p>
<p>The rules, instituted by Environment Canada, are expected to come out in February, according to a news release issued by PEN earlier this week.</p>
<p>Canadian companies that manufactured or imported 1 kg or more of engineered nanoparticles in 2008 will be required to provide information about how the substance is used or managed and any existing data on their physical or chemical properties. It is a one-time requirement. The Canadian government will then use the information to evaluate possible risks to the public and the environment.</p>
<p>The regulations would be in line with a proposed regulatory framework released by Environment Canada and Health Canada in September 2007.</p>
<p>One problem with the rule, Gordon said, is that there are not too many Canadian nanotech companies around to regulate. And these rules could be the nail in the coffin.</p>
<p>"I have observed first-hand how the Canadian government had ignored the massive economic development opportunity from nanotechnology," he said.</p>
<p>"The Canadian government’s informal nanotechnology policy of allocating its limited nanotechnology funding almost exclusivity to government labs and government-owned universities has created a void of Canadian nanotechnology companies which for the most part are struggling to survive or have left Canada."</p>
<p>It is important to remember, too, Gordon said, that the question is not simply which substances are toxic, but also whether they are toxic in the small amounts used inside nanotech products.</p>
<p>Many of the current research on nanoparticle toxicity expose test animals to artificially high amounts of nanomaterials.</p>
<p>"A fish can die from eating too much fish food," Gordon said. "If the amount of nanoparticles in a product are at some miniscule level, as is typical for nano products, then the risk must account for what is really being used -- not some artificially high amount."</p>
<p>But it is just this shortage of information on nanoparticles that makes these rules needed, Maynard indicated.</p>
<p>"This decision by Canada -- to establish the world's first national mandatory nanoscale materials reporting program for companies -- is an important step toward ensuring that nanotechnology regulation is driven by accurate information and high-quality science," he said in a news release.</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-7821797824219304570?l=smalltechtalk.blogspot.com' alt='' /></div>tag:blogger.com,1999:blog-6331358152894046568.post-78217978242193045702009-01-30T20:17:00.000Z2011-12-16T14:50:28.037ZU.S., at last, begins assault on firstname.lastname@example.orgPete Singer<p>If you could just tune your ears above the recent clatter and racket that passed for debate over a bridge loan for the Big Three, you might have been able to just make out the tiny baby cries of a newborn U.S. auto industry.</p>
<p>I live in Detroit, so I heard the slap on that baby's ass, followed by the opening shrieks of a brat already born into a disadvantaged, dysfunctional family.</p>
<p>You see, in the literal power struggle over the next age of the automotive industry -- the electric age -- the U.S. battery industry is arriving late.</p>
<p>It's not that innovation is lacking. Some of the leading research into nanotech-enabled lithium-ion batteries is being done <a href="http://nanobot.blogspot.com/2008/11/nano-powering-auto-revolution.html" target="new">right in my hometown</a>. But only now has it dawned on the federal and state governments to push that innovation forward through financial aid and tax breaks. And only now have U.S. battery companies realized that they can combine some of their efforts to bring those innovations from the lab to the marketplace.</p>
<p>Late and late.</p>
<p>But hopefully not too late.</p>
<p>Two years and an economic lifetime ago, I covered the Detroit auto show when a proud Bob Lutz <a href="http://www.nanobotmedia.com-a.googlepages.com/BusinessReview_ChryslerGMgobacktothe.pdf" target="new">unveiled the Chevrolet Volt</a> (PDF 219k) hybrid electric concept vehicle to a great many ooohs and aahhhs even from the jaded press.</p>
<p>But a few months later, at the Society of Automotive Engineers' 2007 World Congress, <a href="http://blog.mlive.com/oak_business_review/2007/04/oakland_companies_work_on_late.html#more" target="new">I peaked under the hood</a> of all that shiny new plastic and found disparate and desparate U.S. and European engineers sweating it out for what they assumed would be second place in the race to create safe, long-lasting batteries for vehicles like the Volt.</p>
<p>Today, the race is still for second place, behind Asia. And, as I covered the North American International Auto Show again this year, it looks like nanotechnology has come in second, too. GM chose Compact Power, a subsidiary of the Asian LG Chem, to provide the lithium-ion batteries for the Volt. A close second was A123 Systems, whose nanophosphate formula is an important ingredient in its li-ion batteries. The reason, according to GM, was the the formula seemed too experimental, the company too inexperienced and, most importantly, the battery manufacturing infrastructure just does not yet exist in the United States.</p>
<p>To its credit, GM is working on building its own battery infrastructure from the ground up. Another lesson learned from Toyota. So, there is still hope for nano-enhanced li-ion batteries, as there will be room for many players, eventually.</p>
<p>It's about time.</p>
<p>Of course, not in time to save my <a href="http://nanobot.blogspot.com/2008/12/innovation-in-detroit-yes-detroit.html" target="new">Motown hometown from further pain</a>. But perhaps enough to implant an embryo that will, in time, give birth to a brand spanking new auto industry.</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-3271790894460072794?l=smalltechtalk.blogspot.com' alt='' /></div>tag:blogger.com,1999:blog-6331358152894046568.post-32717908944600727942009-01-16T18:20:00.000Z2011-10-23T02:42:06.910ZNow Is The Time to Invest Says Pennnoemail@noemail.orgPete SingerA press release popped into my e-mail this morning from Malcolm Penn of Future Horizons. Here's what he's saying: "Amidst all the doom and gloom, now is the time to make investments and come out of the recession strong," Penn said. By investing now companies can secure their long-term future and come out of the recession in a great position.
"R&D is always one of the first things to get cut in times of economic crisis," says Penn. "But by doing this companies are harming their long term future. If they don’t continue to look forward now, they will be behind the competition in 12 months time – and find themselves in even greater trouble. While the short term gains of cost cutting are obvious, in the long run it will come back to bite. By taking the lead now companies can seize the initiative, and come out of these difficult times in a strong position." Penn was speaking ahead of the 2009 Forecast Seminar that is taking place in London.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-7524092747619627201?l=smalltechtalk.blogspot.com' alt='' /></div>tag:blogger.com,1999:blog-6331358152894046568.post-75240927476196272012008-12-15T13:50:00.000Z2011-12-16T14:50:30.642ZBoy does the economy email@example.comPete SingerThe extent of the financial crisis is still unknown, of course, and most agree that it will get worse before it gets better, but at <em>Small Times</em> and <em>Solid State Technology</em> magazine we have been gathering reports from leading market forecasters and analysts and can share what they’re telling us. I think MEMS and nanotech will weather the storm well, but it looks like some rough sailing ahead for my semiconductor friends.
The good news is that market fundamentals are quite different than they were in 2001. “Staring a global economic recession in the face, will 2009 be a re-run of 2001? We think no,” said Malcolm Penn, CEO of Future Horizons, Kent UK. Penn said that downturns in the semiconductor industry over the last 60 years were always caused by excess capacity, triggered either by demand or supply side issues e.g., by over investment (making capacity overshoot demand) or a demand slowdown (whether through an inventory burn or recession) making short-term capacity exceed near-term demand. “The 2001 slowdown was unique in that it was triggered by both demand and supply-side issues, namely; the collapse of dot-com inflated demand euphoria, a 9-11 driven economic slowdown, a resultant massive inventory burn, just as a huge amount of excess capacity was coming on stream,” Penn said. “Entering 2009, we have no serious overcapacity in place (pre-slowdown utilization rates were in the 90% region), a cap ex cut back that started 12-18 months before the slowdown hit, and IC ASPs in the middle of a cyclical upward trend. In addition, IC units had been running at or below the 10%/yr long-term trend line, with no serious excess inventory in the supply chain. For once, the industry is in structurally good shape to enter a recession. This will make the 2009 downturn statistically shorter than it would otherwise have been,” Penn added.
Bill McClean, President of IC Insights, Scottsdale, Arizona, believes the effect of a global recession on the worldwide semiconductor market in 2009 depends greatly on the magnitude and duration of the recession. “A severe U.S. recession and steep global recession (i.e., worldwide GDP growth of <2.0%) would probably cause the worldwide semiconductor market to show a 10% decline,” McClean said. He further states that worldwide semiconductor industry capital spending is forecast to decline 15% in 2009 after falling 24% in 2008. “Even with these cutbacks in spending, IC ASPs are expected to fall another 6% in 2009, the same as the decline forecast for 2008. However, as a direct result of these steep capital spending declines, and a capital spending as a percent of sales ratio that is likely to reach an all-time low (15%) in 2009, IC ASPs are forecast to rebound (very strongly for DRAM and NAND flash memory) and spur double-digit semiconductor industry market growth in 2010, 2011, and 2012.”
Aida Jebens, Sr. Economist, VLSI Research, Santa Clara, California, said that despite all the negative sentiments about the economy, she does not believe electronics sales will be in negative territory next year for several reasons: “With the exception of 2000-2001, there has never been a case in history when an economic slowdown or recession resulted in a drop in electronics sales. The 2000-2001 period is different because it was driven by the Y2K tech boom and was made worse by the terrorist attacks. We do not have the same situation today. We simply have a very nervous sentiment because of the economy. Electronics tend to do well in a slow economy. At the consumer level, people tend to cocoon in their homes when times are tough. Instead of going away on vacation, or going out for entertainment, they tend to buy electronics. At the business level, sure there will be a pullback in spending on high-end servers, but even in recessions, businesses tend to buy computers and peripherals, and networking hardware to improve efficiency and boost productivity,” Jebens said. VLSI expects both consumer and business spending to stagnate in 2009, resulting in a very slight 3.5% growth in electronics. At this rate, worldwide electronics shipments should amount to $1.7B.
Klaus Rinnen, Managing VP, Gartner, Washougal, Washington, said that Gartner now expects 2008 semiconductor growth to be ~2%, and predicts that, in 2009, the market will experience anything between a decline of 2% and growth of 1%. “In addition, we currently expect a capital spending decline of ~17% in 2009, and capital equipment to drop roughly 18%. In excess condition for all of 2008, we believe inventories will rise in 4Q, overshadowing demand and reducing production needs for 1H 2009. This will lead to a reduction in factory utilization,” Rinnen said. “Continued weakness in memory sectors combined with reduced production due to increased inventory levels are causing many manufacturers to drop spending projections. Memory financials continue to worsen, causing suppliers with cash flow problems to delay or eliminate capacity expansions. Some vendors are even postponing investments for needed technology improvements because of profitability problems.”Next week will, of course, will provide us all with an interesting barometer in the form of consumer spending in the U.S. on the day after Thanksgiving, the so-called “Black Friday.” Traditionally, it is one of the busiest shopping days of the year, putting merchants into the “black.” I'm hoping everyone is out buying the latest electronic gizmos!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/6331358152894046568-6724435822463128003?l=smalltechtalk.blogspot.com' alt='' /></div>tag:blogger.com,1999:blog-6331358152894046568.post-67244358224631280032008-11-21T13:35:00.000Z2011-12-16T14:50:30.845ZWelcome to Small Tech Talknoemail@noemail.orgPete SingerWelcome to my Small Times blog. Since this is the first of what will hopefully be many posts, I’d like to briefly share my personal perspective on micro- and nanotechnology and my plans for Small Times as the new Editor-in-Chief.
First and foremost, let me assure you that I clearly see the difference between working at very small dimensions and nanotechnology. During my 26+ years working as a technology editor, I have mostly focused on the semiconductor manufacturing industry. To give credit where credit is due, there can be no question that the true pioneers of nanotechnology are semiconductor guys. They have been working at nano dimensions for years -- the thickness of a gate dielectric on advanced integrated circuits in manufacturing today is less than 10 atoms thick, for example – and much of what we know about how electrons and ions and atoms behave at the nanoscale has come from semiconductor research work. Innovations such as the atomic force microscope and the advancements made in carbon nanotube research largely stem for such work as well.
There’s a big difference though, between relentless scaling of dimensions as has been the course of the semiconductor industry (at least to date) versus what most consider the real potential of nanotechnology: changing and controlling the very essence of matter itself, often in strange new ways. Richard Feynman described this well in his now famous talk in 1959: “There's Plenty of Room at the Bottom: An Invitation to Enter a New Field of Physics.” <a href="http://www.zyvex.com/nanotech/feynman.html">http://www.zyvex.com/nanotech/feynman.html</a>
What’s happened over the last decade, of course, is that basic semiconductor device research and straightforward materials science has been recast as “nanotechnology” research. In some ways, I think this has been driven by an understandable desire to get on the nanotech bandwagon in order to not miss out on billions of dollars in government and VC funding. But it’s also because the semiconductor industry’s scaling has reached some fundamental limits. A new “switch” needs to be found, and nanotech offers up a tantalizing array of possibilities. A good overview of this can be found on the Intel website: <a href="http://download.intel.com/technology/silicon/nano-open-house-george-bourianoff.pdf">http://download.intel.com/technology/silicon/nano-open-house-george-bourianoff.pdf</a>
I’ll be talking/blogging about all these kind of things, as well as some of the nonsense related to the perceived threat to public health safety posed by nano. I’ll also be zeroing in on some the dynamic work now underway at the university level.
The focus of Small Times magazine, however, will be less on gee-whiz nanotech and more on practical applications and the manufacturing know-how that's used to produce devices for those applications. Progress in Microelectromechanical systems (MEMS) in particular will be highlighted. Everyone seems to define MEMS a little differently, but to me it’s an amalgamate of many diverse functions, from accelerometers to microfluidics, from energy harvesting piezoelectric devices to fuel cells, from RFMEMS to wireless sensors.
As always, let me know what you think.
