As part of ongoing research to make hydrogen a mainstream source of clean, renewable energy, scientists from the U.S. Department of Energys Brookhaven National Laboratory have determined how titanium atoms help hydrogen atoms attach to an aluminum surface. Their study isolates the role of titanium, which is used as a catalyst in the crucial first step to trap hydrogen within a particular class of hydrogen-storage materials. The work may also help identify and develop similar hydrogen-storage systems.
Brookhaven chemist Santanu Chaudhuri will present this research at the 230th national meeting of the American Chemical Society in Washington, D.C. The talk is scheduled for Thursday, September 1, at 3:40 p.m. in room 142 of the Washington Convention Center.
To be a mainstream source of fuel, hydrogen must be stored safely and efficiently. Conventional high-pressure storage tanks can be dangerous and are too big and heavy for certain applications, such as hydrogen-based fuel cells in automobiles. Hydrogen-storage materials, however, incorporate hydrogen safely and compactly, and temporarily hold large quantities of it that can be recovered easily under safe, controlled conditions.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
