Researchers at Oregon State University have created a new, unifying method to describe a basic chemical concept called “electronegativity,” first described almost 80 years ago by OSU alumnus Linus Pauling and part of the work that led to his receiving the Nobel Prize. The new system offers simplicity of understanding that should rewrite high school and college chemistry textbooks around the world, even as it opens important new avenues in materials and chemical research, with...

Material designed for energy applications is 10 times faster than natural enzyme, uses inexpensive metals Looking to nature for their muse, researchers have used a common protein to guide the design of a material that can make energy-storing hydrogen gas. The synthetic material works 10 times faster than the original protein found in water-dwelling microbes, the researchers report in the August 12 issue of the journal Science, clocking in at 100,000 molecules of hydrogen gas every second....

An approach pioneered by researchers at North Carolina State University gives scientists new insight into the way silicon bonds with other materials at the atomic level. This technique could lead to improved understanding of and control over bond formation at the atomic level, and opportunities for the creation of new devices and more efficient microchips. Manufacturers build silicon-based devices from layers of different materials. Bonds "“ the chemical interaction between adjacent...

Rice researchers find metallacarboranes may meet DOE storage goals New research by Rice University scientists suggests that a class of material known as metallacarborane could store hydrogen at or better than benchmarks set by the United States Department of Energy (DOE) Hydrogen Program for 2015. The work could receive wide attention as hydrogen comes into play as a fuel of the future for cars, in fuel cells and by industry. The new study by Rice theoretical physicist Boris Yakobson and his...

Scientists at the National Research Council of Canada (NRC) and the University of Ottawa (uOttawa) enjoyed a bird's eye view of a chemical bond as it breaks. The making and breaking of chemical bonds underlie the biochemical processes of life itself. A greater understanding of the quantum processes that lead to chemical reactions may lead to new strategies in the design and control of molecules "” ultimately leading to scientific breakthroughs in health care and diagnostic medicine,...
