Physicists have long wondered whether hydrogen, the most abundant element in the universe, could be transformed into a metal and possibly even a superconductor"”the elusive state in which electrons can flow without resistance. They have speculated that under certain pressure and temperature conditions hydrogen could be squeezed into a metal and possibly even a superconductor, but proving it experimentally has been difficult. High-pressure researchers, including Carnegie's Ho-kwang...

Study suggests strategies for converting hydrogen to metal at significantly lower pressures Scientists have a long and unsuccessful history of attempting to convert hydrogen to a metal by squeezing it under incredibly high and steady pressures. Metallic hydrogen is predicted to be a high-temperature superconductor. A superconductor is a state of matter where electrons, and thus electricity, can flow indefinitely and without resistance. In a paper published this week in the online edition of...

 Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form. Rice University chemists have answered the call this week with a polymer-coated version of gold-platinum nanorods, the first catalysts of their kind that can be used in the organic solvents favored by chemical and drug manufacturers.The research is available online in the Sept. 1 issue of the German scientific journal Angewandte Chemie...

 To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. A gas flows easily out of a tank, but getting hydrogen out of a molecule requires a catalyst. Now, researchers reveal new details about one such catalyst. The results are a step toward designing catalysts for use in hydrogen energy applications such as fuel cells.Scientists from the Department of Energy's Pacific Northwest National...

Hydrogen, the most common element in the universe, is normally an insulating gas, but at high pressures it may turn into a superconductor. Now, scientists at the Carnegie Institution in Washington D.C., US, have discovered a hydrogen-based compound that could be helpful in the search for metallic and superconducting forms of hydrogen. The results are reported in Physical Review Letters and highlighted in the August 3rd issue of APS's on-line journal Physics (physics.aps.org).Hydrogen is the...

Researchers at the U.S. Department of Energy's Savannah River National Laboratory have created a reversible route to generate aluminum hydride, a high capacity hydrogen storage material. This achievement is not only expected to accelerate the development of a whole class of storage materials, but also has far reaching applications in areas spanning energy technology and synthetic chemistry."We believe our research has provided a feasible route to regenerate aluminum hydride, a high capacity...

Scientists in Delaware say they have developed a new hydrogen storage method "” carbonized chicken feather fibers "” that can hold vast amounts of hydrogen, a promising but difficult to corral fuel source, and do it at a far lower cost than other hydrogen storage systems under consideration. The research, presented here today at the 13th Annual Green Chemistry & Engineering Conference, could eventually help overcome some of the hurdles to using hydrogen fuel in cars, trucks...

A hydrogen-rich compound discovered by Stanford researchers is packed with promise of helping overcome one of the biggest hurdles to using hydrogen for fuel--namely, how do you stuff enough hydrogen into a volume that is small enough to be portable and practical for powering a car? The newly discovered material is a high-pressure form of ammonia borane, a solid material which itself is already imbued with ample hydrogen. By working with the parent material at high pressure in an atmosphere...

Aluminum (or aluminium) is a soft, lightweight, silvery metal. It is an element in the boron group on the periodic table of elements, with the symbol Al and atomic number 13. On the earth's crust, aluminum is the most abundant metal, and the third most abundant of all elements on the earth's crust, after oxygen and silicon. It accounts for 8% of the weight of the Earth's solid surface. Because aluminum is a highly reactive metal, it doesn't occur in nature in a pure form. Aluminum forms a...

Lithium is the chemical element with symbol Li and atomic number 3. In the periodic table, it is located in group 1, among the alkali metals. Lithium in its pure form is a soft, silver white metal, that tarnishes and oxidizes very rapidly in air and water. It is the lightest solid element and is primarily used in heat transfer alloys, in batteries and serves as a component in some drugs known as mood stabilizers. Notable characteristics Lithium is the lightest metal and has a density...
