As science enters the world of the very small, researchers will be searching for new ways to study nanoparticles and their properties. For the past several years, scientists at the U.S. Department of Energys Brookhaven National Laboratory have been experimenting with new methods for preparing nanoparticles on metal supports, with the aim of creating model catalyst systems to better study the special reactivity of nano-sized catalyst particles.
Brookhavens Jan Hrbek will review several of the Labs results at the 231st national meeting of the American Chemical Society at the Georgia World Congress Center in Atlanta, GA. Hrbeks talk will be held on Monday, March 27 at 2:40 pm in Room C209.
Catalysis, the acceleration of a chemical reaction, is tremendously important as an industrial process, underlying most of our energy supply (oil-to-fuel conversion, for example) and 80 percent of the products of the chemical industry. There is a substantial need to understand how catalysts work, and learn to design and make better catalysts. The work at Brookhaven is aimed at understanding how the detailed atomic structures of model systems of certain classes of catalysts contribute to their activity. Hrbeks talk will review work in making models of nanometer scale particles that are the active material in many catalyst particles.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
