While high-density lipoprotein, or HDL, the so-called good cholesterol, is transferred to the liver for processing, low-density lipoprotein, or LDL, builds up in the arteries in the form of plaque.<br />
<br />
Early detection of cellular components in the plaque that rupture and block arteries have long been held as potentially effective detection for heart diseases and their link to atherosclerosis.</span><br />

<br />
<span style="background-color: white; font-family: Arial, Helvetica, Sans; font-size: 12px;">Carbon nanotubes - a manmade material - have been the focus of an enormous amount of research during the last decade due to their extraordinary electrical and optical properties. These tubes are many times thinner than a wavelength of visible light which makes them promising candidates for being used as pixels.</span><br />

<br />
<span style="background-color: white; font-family: Arial, Helvetica, Sans; font-size: 12px;">"PRAM uses reversible phase changes between the crystalline (low resistance) and amorphous (high resistance) state of chalcogenide materials, which corresponds to the data "0" and "1," respectively. Although PRAM has been partially commercialized up to 512 Mb by Samsung Electronics Co., Ltd., its writing current should be decreased by at least one-third of its present level for the mass production of mobile electronics applications. A team of Professors Keon Jae Lee and Yeon Sik Jung in the Department of Materials Science and Engineering at KAIST has developed phase-change memory with low power consumption (below 1/20th of its present level) by employing self-assembled block copolymer (BCP) silica nanostructures. Their work was published under the title "Self-Assembled Incorporation of Modulated Block Copolymer Nanostructures in Phase-Change Memory for Switching Power Reduction" in the March issue of ACS Nano."</span><br />

3D Systems Corporation (DDD) reported earnings on February 25th. The company reported adjusted EPS of $0.39 (before split), a cent over views, but missed revenue expectations, as it reported $101.6 million, and analysts were expecting $103.86 million. Revenue was up 45% over the same quarter last year, and 54% for the year, reaching $354.6 million.<br />
<br />
The management said on the conference call that the company introduced 16 new products, and that revenue from new products increased 70% to $131.9 million. Gross margin expanded 390 basis points to 51.2%. Organic growth for the year was 22.4% and 18.8% in the fourth quarter.<br />

New Research promises cheaper ultra-light thin film solar panels and the basis of a low-cost tool for 3D printing of these thin film circuits.<br />
<br />
<span style="background-color: white; font-family: Arial, Helvetica, Sans; font-size: 12px;">"Scientists from Imperial College London, working at the Institut Laue-Langevin, have presented a new way of positioning nanoparticles in plastics, with important applications in the production of coatings and photovoltaic material that harvest energy from the sun. The study, presented in Advanced Materials (cover article), used neutrons to understand the role that light – even ambient light – plays in the stabilisation of these notoriously unstable thin films. As a proof of concept the team have shown how the combination of heat and low intensity visible and UV light could in future be used as a precise, low-cost tool for 3D printing of self-assembling, thin-film circuits on these films."</span><br />

<br />
"<span style="color: #4a4a4a; font-family: Arial, sans-serif; font-size: 15px; line-height: 23px;">A NEW range of televisions from Sony is the first to use minuscule devices known as quantum dots to produce colours which are more vibrant than those which appear on a conventional liquid-crystal display (LCD). Quantum dots are crystals of semiconductor material just a few nanometres (billionths of a metre) in size. They could have a big future in lighting and display technologies, but are difficult and expensive to manufacture, and use toxic materials. However, Geoffrey Ozin, from the University of Toronto, Uli Lemmer, from the Karlsruhe Institute of Technology, in Germany, and their colleagues believe they have found a way to deal with these problems."</span><br />

3D Systems Corporation (NYSE:DDD) is one of the latest stocks in the whole '3D printing' scene, fourth-quarter revenue shortfall heightened concerns Monday about 3D printer stocks.<br />
3D Systems said Q4 revenue rose 45% to $101.6 million. That lagged consensus estimates for $103.9 million.<br />

One of the new display technologies is the Mirasol display from Qualcomm. This MEMS (microelectromechanical-system)-on-glass device targets low-power, daylight-readable color displays for portable-system applications.<br /><br />Most LCD devices operating at low power, such as with mobile phones and tablet PCs, have issues with color representation. In varying light, the color accuracy of the display changes, altering the viewer’s perception of the image. The Mirasol display attempts to overcome these issues.<br /><br />The display is a front-reflective display rather than a traditional backlit display. The properties of nanoscale materials combine with advanced MEMS-processing techniques, allowing the display to mimic naturally occurring phenomena. The display works by creating a color from an interference pattern on the reflected light that hits the top of the display. This process is the same one that makes a butterfly’s wing shimmer and display different colors.</blockquote><br /><a href="http://www.edn.com/article/509646-Nano_drives_improve_displays.php">Source</a>Unknownnoreply@blogger.com2tag:blogger.com,1999:blog-12226671.post-1049652478325709872010-05-20T12:30:00.001-07:002010-05-20T12:30:56.541-07:0096% Solar Efficiency<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://cdn.physorg.com/newman/gfx/news/nearperfects.jpg"><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 280px; height: 206px;" src="http://cdn.physorg.com/newman/gfx/news/nearperfects.jpg" border="0" alt="" /></a><br /><blockquote>A new anti-reflective coating developed by researchers at Rensselaer Polytechnic Institute could help to overcome two major hurdles blocking the progress and wider use of solar power. The nanoengineered coating boosts the amount of sunlight captured by solar panels and allows those panels to absorb the entire spectrum of sunlight from any angle, regardless of the sun's position in the sky. <br />An untreated silicon solar cell only absorbs 67.4 percent of sunlight shone upon it — meaning that nearly one-third of that sunlight is reflected away and thus unharvestable.<br /><span style="font-weight:bold;">After a silicon surface was treated with Lin's new nanoengineered reflective coating, however, the material absorbed 96.21 percent of sunlight shone upon it </span>— meaning that only 3.79 percent of the sunlight was reflected and unharvested. This huge gain in absorption was consistent across the entire spectrum of sunlight, from UV to visible light and infrared, and moves solar power a significant step forward toward economic viability.</blockquote><br />Source: <a href="http://www.physorg.com/news144940463.html">PhysOrg</a>Unknownnoreply@blogger.com3tag:blogger.com,1999:blog-12226671.post-18455550702339332312010-05-15T15:25:00.001-07:002010-05-15T15:31:36.070-07:00DNA and molecular factories<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://i.i.com.com/cnwk.1d/i/tim//2010/05/13/DNAimage.png"><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 150px;" src="http://i.i.com.com/cnwk.1d/i/tim//2010/05/13/DNAimage.png" border="0" alt="" /></a><br /><blockquote>If you thought nanobots might give us cause for concern when the singularity occurs, how about nanobots made from DNA?

But the energy in trees is something else entirely. The potato experiment uses electrodes of two different metals to set up a charge difference that gets local electrons flowing. <br /><br />But in the current study, researchers use electrodes made of the same material. Sticking one electrode into a tree and another in the soil, they found that big leaf maples generate a steady voltage of up to a few hundred millivolts. That’s way less than the volt-and-a-half provided by a standard AA battery.

They even claim that the battery still works when the paper is crumbled into a ball.<br /><br />"Society really needs a low-cost, high-performance energy storage device, such as batteries and simple supercapacitors," said Yi Cui, assistant professor of materials science and engineering.
