Researchers at the Department of Energys Pacific Northwest National Laboratory are developing a system to rapidly produce hydrogen from gasoline in your car. "This brings fuel cell-powered cars one step closer to the mass market," said Larry Pederson, project leader at PNNL. Researchers will present their developments at the American Institute for Chemical Engineers spring meeting in New Orleans, on April 27th, 2004.
Fuel cells use hydrogen to produce electricity which runs the vehicle. Fuel cell-powered vehicles get about twice the fuel efficiency of todays cars and significantly reduce emissions. But how do you "gas up" a hydrogen car? Instead of building a new infrastructure of hydrogen fueling stations you can convert or reform gasoline onboard the vehicle. One approach uses steam reforming, in which hydrocarbon fuel reacts with steam at high temperatures over a catalyst. Hydrogen atoms are stripped from water and hydrocarbon molecules to produce hydrogen gas.
The problem has been that you have to wait about 15 minutes before you can drive. It has taken steam reformer prototypes that long to come up to temperature to begin producing hydrogen to power the vehicle. This delay is unacceptable to drivers.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
