Putting the squeeze on nitrogen for high energy materials Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen. view more (2008-09-04)
Heavier hydrogen on the atomic scale reduces friction Scientists may be one step closer to understanding the atomic forces that cause friction, thanks to a recently published study by researchers from the University of Pennsylvania, the University of Houston and the U.S. Department of Energy's Argonne National Laboratory. view more (2007-11-05)
Nanoengineers mine tiny diamonds for drug delivery Northwestern University researchers have shown that nanodiamonds -- much like the carbon structure as that of a sparkling 14 karat diamond but on a much smaller scale -- are very effective at delivering chemotherapy drugs to cells without the negative effects associated with current drug delivery agents. view more (2007-10-15)
Huge pressures that melt diamond on planet Neptune determined by Sandia researchers The enormous pressures needed to melt diamond to slush and then to a completely liquid state have been determined ten times more accurately by Sandia National Laboratories researchers than ever before. view more (2009-02-18)
Laser-induced shocks in diamond anvil can achieve pressures inside supergiant planets Combining diamond anvils and powerful lasers, laboratory researchers have developed a technique that should be able to squeeze materials to pressures 100 to 1,000 times greater than possible today, reproducing conditions expected in the cores of supergiant planets. view more (2007-05-03)
Researchers locate mantle's spin transition zone, leading to clues about Earth's structure Researchers have located the spin transition zone of iron in Earth's lower mantle, a discovery which has profound geophysical implications. view more (2007-09-24)
UCSB researchers show how to make polymeric micro- and nanoparticles Researchers in the College of Engineering at UC Santa Barbara have discovered how to make polymeric micro- and nanoparticles in a wide variety of different shapes and sizes using commonly-available lab chemicals and equipment. view more (2007-07-10)
No Core In Volcanoes A hot debate in the Earth Sciences is finally resolved in this week's issue of Nature. Researchers from the Department of Earth Sciences at Bristol University show that large volcanoes do not contain material from the Earth's core. This overturns previous theories that conflicted with models of how the Earth's magnetic field is sustained. The... view more... (2004-01-12)
Getting the most out of gemstones "We were astounded when our customer, Markus Wild, approached us and we were not at all certain whether mathematics could offer a solution for the very complex problem of volume optimization of gemstones," says Dr. Anton Winterfeld from the Fraunhofer Institute for Industrial Mathematics ITWM. view more (2009-06-26)
Alloy of hydrogen and oxygen made from water Water, the only indispensable ingredient of life, is just about the most versatile stuff on Earth. Depending on its temperature we can heat our homes with it, bathe in it, and even strap on skates and glide across it, to name only the most common of its many forms. When subjected to high pressures, however, water can take any of more than 15... view more... (2006-10-27)
Minerals go 'dark' near Earth's core Minerals crunched by intense pressure near the Earth's core lose much of their ability to conduct infrared light, according to a new study from the Carnegie Institution's Geophysical Laboratory. view more (2006-05-26)
Nanotech discovery could have radical implications It has been 20 years since the futurist Eric Drexler daringly predicted a new world where miniaturized robots would build things one molecule at a time. The world of nanotechnology that Drexler envisioned is beginning to come to pass, with scientists conjuring new applications daily. view more (2005-12-01)
University of Surrey Electronic Engineers' Revolutionary Discovery A University of Surrey team led by Professor Ravi Silva has demonstrated a new method of growing carbon nanofibres at room temperature. Published in this week's Nature Materials, the technique they have used involves substituting the thermal energy requirements for growth with plasma decomposition of methane on the Ni catalyst. Professor Silva... view more... (2002-10-23)
Z machine melts diamond to puddle Sandia's Z machine, by creating pressures more than 10 million times that of the atmosphere at sea level, has turned a diamond sheet into a pool of liquid. view more (2006-11-06)
6 North American sites hold 12,900-year-old nanodiamond-rich soil Abundant tiny particles of diamond dust exist in sediments dating to 12,900 years ago at six North American sites, adding strong evidence for Earth's impact with a rare swarm of carbon-and-water-rich comets or carbonaceous chondrites, reports a nine-member scientific team. view more (2009-01-05)
Baseball diamonds: the lefthander's best friend Baseball diamonds are a left-hander's best friend. That's because the game was designed to make a lefty the "Natural," according to David A. Peters, Ph.D., the McDonnell Douglas Professor of Engineering at Washington University in St. Louis and über baseball fan. Peters is a mechanical engineer who specializes in aircraft and... view more... (2008-07-08)
CBEN: Buckyball aggregates are soluble, antibacterial In some of the first research to probe how buckyballs will interact with natural ecosystems, Rice University's Center for Biological and Environmental Nanotechnology finds that the molecules spontaneously clump together upon contact with water, forming nanoparticles that are both soluble and toxic to bacteria. view more (2005-06-23)
IUPUI study finds living near fast food outlet not a weighty problem for kids A new study by Indiana University-Purdue University Indianapolis (IUPUI) researchers contradicts the conventional wisdom that living near a fast food outlet increases weight in children and that living near supermarkets, which sell fresh fruit and vegetables as well as so called junk food, lowers weight. view more (2009-06-17)
New nanotech products hitting the market at the rate of 3-4 per week New nanotechnology consumer products are coming on the market at the rate of 3-4 per week, a finding based on the latest update to the nanotechnology consumer product inventory maintained by the Project on Emerging Nanotechnologies (PEN). view more (2008-04-25)
Medicine and Biology at the Institute of Physics Congress Brighton Conference Centre, 27-30 March In-Vitro Bio-Medical Sensing Monday 27 March 2000 Bodily fluids can be screened for the presence of infections by a range of tests using relatively simple technology. X-rays can analyse molecular structures and may be used to distinguish between healthy, benign and malignant breast tissue. In other areas of research, microtechnology is playing an... view more...
