Beyond the bonds that bind: UCSB researchers discover hydrogen can form multicenter bonds
Researchers at the University of California, Santa Barbara have shown that, under the right circumstances, hydrogen can form multicenter bonds, where one hydrogen atom simultaneously bonds to as many as four or six other atoms. view more (2006-12-04)
Warm water vibrates for longer
Dutch researcher Arjan Lock has investigated the behaviour of vibrating water molecules. Using ultra-short laser pulses, he found that hydrogen atoms in water molecules vibrate for longer at higher temperatures. This is abnormal because in the majority of substances a vibration lives shorter at higher temperatures. Lock studied the OH-stretch... view more... (2004-02-05)
On the path to metallic hydrogen
Hydrogen, the most common element in the universe, is normally an insulating gas, but at high pressures it may turn into a superconductor. view more (2009-08-04)
Strange molecule in the sky cleans acid rain, scientists discover
Researchers have discovered an unusual molecule that is essential to the atmosphere's ability to break down pollutants, especially the compounds that cause acid rain. view more (2008-08-13)
Solvents in Retreat
A new catalyst for selective solvent-free hydrogenation at low temperatures A number of cyclic hydrocarbons with multiple double bonds are readily accessible intermediates in chemical industry. In the course of further processing it is often necessary to saturate some of the double bonds with hydrogen to form single bonds. This type of reaction,... view more... (2001-03-27)
The short-term memory of water
Researchers of the Max-Born-Institute and the University of Toronto find extremely fast fluctuations in liquid water - Publication in Nature. view more (2005-03-07)
Breaking harmful bonds
Everybody loves the way breakfast eggs conveniently slide off of Teflon without leaving any pesky pieces of egg in the pan. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even blood substitutes. view more (2008-08-29)
Breaking the Ties that Bind: New Hope for Biomass Fuels
Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. view more (2009-04-23)
Hydrogen bonds shown to play 'conserved' role in protein folding
By changing individual atoms in key places in proteins, Duke University chemists have found new evidence for the importance of comparatively weak "hydrogen bonds" in enabling stringlike proteins to fold into the maximally stable shape they need to assume their roles as biological workhorses. view more (2006-02-13)
New laser technique that strips hydrogen from silicon surfaces
A team of researchers have achieved a long-sought scientific goal: using laser light to break specific molecular bonds. The process uses laser light, instead of heat, to strip hydrogen atoms from silicon surfaces, a key step in the manufacture of computer chips and solar cells. view more (2006-05-19)
What happens when ice melts?
How molecules are linked together to form liquid water is the subject of a groundbreaking study due to appear Thursday, Apr. 1 in Science magazine's advance publication web site Science Express. The investigation entitled The Structure of the First Coordination Shell in Liquid Water summarizes the results of an international collaboration headed... view more... (2004-04-02)
Researchers shed more light on conversion of water to hydrogen gas
Chemists are several steps closer to teasing hydrogen fuel from water using man-made molecular devices that collect electrons and use them to split hydrogen from oxygen. view more (2005-08-29)

Water is 'designer fluid' that helps proteins change shape, scientists say
Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought. view more (2008-08-07)
Pitt professor designs less-risky reactor for clean, safe energy
Reactors that burn hydrogen or natural gas to generate energy can be dirty and dangerous. The mix of air with hydrogen or natural gas can explode easily if composition and temperature are not carefully controlled. And reactors often produce polluting byproducts. view more (2006-09-13)
Rehydrate - your RNA needs it
Water, that molecule-of-all-trades, is famous for its roles in shaping the Earth, sustaining living creatures and serving as a universal solvent. view more (2006-08-23)
Covering the bases: Quantum effect may hold promise for low-cost DNA sequencing, sensor applications
A ghostly property of matter, called quantum tunneling, may aid the quest for accurate, low-cost genomic sequencing, according to a new paper in Nature Nanotechnology Letters by Stuart Lindsay and his collaborators at the Biodesign Institute of Arizona State University. view more (2009-03-23)
From graphene to graphane, now the possibilities are endless
Ever since graphene was discovered in 2004, this one-atom thick, super strong, carbon-based electrical conductor has been billed as a "wonder material" that some physicists think could one day replace silicon in computer chips. view more (2009-07-31)
A promising step towards more effective hydrogen storage
An international research team led by Swedish Professor Rajeev Ahuja, Uppsala University, has demonstrated an atomistic mechanism of hydrogen release in magnesium nanoparticles - a potential hydrogen storage material. The findings have been published in the online edition of Proceedings of the National Academy of Science (PNAS). view more (2008-06-17)
Genomics reveals mechanism of heat resistance in bacteria
Warm-blooded creatures maintain a relatively stable body temperature that cannot tolerate the stress of intense heat (or cold). view more (2005-08-23)
