When a good nanoparticle goes bad
Researchers at Cornell University recently made a major breakthrough when they invented a method to test and demonstrate a long-held hypothesis that some very, very small metal particles work much better than others in various chemical processes such as converting chemical energy to electricity in... view more (2008-11-11)

Why Sloths Do Not Sleep Upside Down
Several mammal species other than ruminants and camels have a multi-chambered forestomach - kangaroos, hippos, colobus monkeys, peccaries, sloths - but they do not ruminate. As studies on the digestive physiology of these species are largely missing, it is generally assumed that their forestomach... view more (2004-04-07)

New Antibacterial Textiles - Research News in Polymer International
Nano-sized silver particles open way to new breed of antimicrobial materials Scientists can now incorporate silver particles into polypropylene to produce an anti-microbial material that could be used in anything from carpets, to napkins and surgical masks. Silver has been medically proven to kill... view more (2003-06-23)

Magnetic nanoparticles assembled into long chains
Chains of 1 million magnetic nanoparticles have been assembled and disassembled in a solution of suspended particles in a controlled way.   view more (2005-10-21)

New particles get a mass boost
A sophisticated, new analysis has revealed that the next frontier in particle physics is farther away than once thought. New forms of matter not predicted by the Standard Model of particle physics are most likely twice as massive as theorists had previously calculated, according to a just-published... view more (2007-10-02)

In the first second of Creation
At the very beginning of the Universe both forms of matter existed in equal amounts. They should have cancelled themselves out leaving just energy. But, within a second, something happened to ensure that matter prevailed - and that the Universe could develop in the way that it did. BaBar should... view more (1999-06-11)

Better composites through right shape of particles
The shape of the small clay particles in polymer-clay composite materials can determine the stiffness, strength and oxygen permeability of the material. The size of the particles determines the sheen and transparency. These are conclusions from the PhD research project of Martin van Es. He will... view more (2001-11-08)

Virginia Tech researcher reports nano-particle dispersion technique improves polymers
There is a lot of excitement about incorporating nano particles into polymers because of the ability to improve various properties with only a small percent of the particles.   view more (2005-08-30)

NC State Engineers Discover Nanoparticles Can Break On Through
In a finding that could speed the use of sensors or barcodes at the nanoscale, North Carolina State University engineers have shown that certain types of tiny organic particles, when heated to the proper temperature, bob to the surface of a layer of a thin polymer film and then can reversibly... view more (2008-09-17)

New DNA-based technique for assembly of nano- and micro-sized particles
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new method for controlling the self-assembly of nanometer and micrometer-sized particles.   view more (2007-09-13)

Air pollution link to clogged arteries
Should we be watching our exposure to airborne pollution as well as our cholesterol levels" Research now indicates that air pollution has a role to play in atherosclerosis (artery hardening), which can contribute to heart attacks or strokes.   view more (2007-07-26)

UCSB researchers show how to make polymeric micro- and nanoparticles

Technologists develop robust soot filter for diesel engine
In a Technology Foundation STW project, Coen van Gulijk has developed a new concept for a robust soot filter for diesel engines. As well as filter stages, the filter has an open canal so as to exclude the danger of blockage and thus fire. The new soot filter consists of series of perforated ceramic... view more (2002-09-11)

Molecular Anatomy of Influenza Virus Detailed
Scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health in Bethesda, Md., and colleagues at the University of Virginia in Charlottesville have succeeded in imaging, in unprecedented detail, the virus that causes... view more (2007-01-02)

UAB Scientists break the hard drive miniaturisation limit
Magnetic memory-based information storage systems are getting smaller and smaller, while their capacities are getting larger. However, there is a limit to how small they can get. If the tiny magnets used to store information are smaller than around five nanometres (millionths of a millimetre),... view more (2003-07-10)

More Diesel - More Allergy
An increasing number of new auto buyers choose diesel engines. For asthmatics and those with allergies this is very unfortunate. Particles in diesel exhaust can both worsen and trigger allergic reactions.   view more (2004-04-30)

Lotus effect shakes off dirt
The lotus - a flowering wetland plant native to Asia - may not at first glance be of interest to the nanotechnologist. But researchers at German chemical company BASF are developing a spray-on coating that mimics the way lotus leaves repel water droplets and particles of dirt. The story is reported... view more (2002-11-08)

National study examines health risks of coarse particle pollution
Researchers at the Johns Hopkins Bloomberg School of Public Health have conducted the largest nationwide study on the acute health effects of coarse particle pollution.   view more (2008-05-14)

Fermions do not travel together, theory proved
Fermions tend to avoid each other and cannot "travel" in close proximity. Demonstrated by a team at the Institut d'optique (CNRS/Université Paris 11, Orsay-Palaiseau), this result is described in detail in the January 25, 2007 issue of Nature. It marks a major advance in our... view more (2007-03-12)

Jupiter`s Electric Aurora
The planet Jupiter has spectacular rings of auroras around each pole but until now scientists have not been able to explain how they form. All auroras are caused by energetic charged particles crashing into the top of the atmosphere and making it glow. In the Earth's auroras, these particles come... view more (2002-03-26)
