In the quest for efficient, cost-effective and commercially viable fuel cells, scientists at Cornell University's Energy Materials Center have discovered a catalyst and catalyst-support combination that could make fuel cells more stable, conk-out free, inexpensive and more resistant to carbon monoxide poisoning.
A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology. The process, called 'photon enhanced thermionic emission', or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.
The Graduate School of Excellence 'Materials Science in Mainz' of Johannes Gutenberg University Mainz, Germany, honored Professor Shoucheng Zhang of Stanford University, California, USA, with the 2010 Gutenberg Research Award.
Hydrogen is considered the fuel of the future. Yet this lightest of the chemical elements can embrittle the metals used in vehicle engineering. The result: components suddenly malfunction and break. A new special laboratory is aiding researchers' search for hydrogen-compatible metals.
Researchers at the University of California, San Diego School of Medicine have identified a new way to regulate the uncontrolled growth of blood vessels, a major problem in a broad range of diseases and conditions.
The concentrations of toxic nitrogen oxide that are present in German cities regularly exceed the maximum permitted levels. That's now about to change, as innovative paving slabs that will help protect the environment are being introduced. Coated in titanium dioxide nanoparticles, they reduce the amount of nitrogen oxide in the air.
In a pioneering research project, for the first time, scientists at IBM and the University of Aberdeen have collaborated to 'see' the structure of a marine compound from the deepest place on the Earth using an atomic force microscope (AFM). The results of the project open up new possibilities in biological research which could lead to the faster development of new medicines in the future.
Researchers have found that silicon, the most widely used material for computer chips and solar cells, can exhibit this strange property of 'retrograde melting' when it contains high concentrations of certain metals dissolved in it.
One Chicago skyline is dazzling enough. Now imagine 15,000 of them. A Northwestern University research team has done just that -- drawing 15,000 identical skylines with tiny beams of light using an innovative nanofabrication technology called beam-pen lithography (BPL).
