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 fuel cells or reducing automobile pollution. 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 functions in the same way as that of ruminants,... view more...

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 study. 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 shed light on that critical event 15 billion years... view more... (1999-06-11)
Tracing ultra-fine dust
Fine particle emissions have been the subject of heated debate for years. People who live near industrial plants see the smoke being discharged into the atmosphere and wonder how harmful it is. view more (2009-10-06)
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 receive his degree at TU Delft on 12 November.... 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 recede below the surface when heated a second time. view more (2008-09-17)
New DNA-based technique for assembly of nano- and micro-sized particles
