Tiny heaters may pave way for easier tissue engineering, medical sensors

Tiny microheaters that can prompt chemical changes in surrounding material may provide the means to more easily grow replacement tissue for injured patients and form the basis for medical sensors that could quickly detect pathogens, according to researchers at the University of Washington who are the first to demonstrate the process.

The key to the technique, according to Associate Professor Karl Böhringer in the UW’s Department of Electrical Engineering, lies in temperature-driven cha

Scientists find new way to store hydrogen fuel

University of Chicago scientists have proposed a new method for storing hydrogen fuel in this week’s online edition of the Proceedings of the National Academy of Sciences.

The lack of practical storage methods has hindered the more widespread use of hydrogen fuels, which are both renewable and environmentally clean. The most popular storage methods-liquid hydrogen and compressed hydrogen-require that the fuel be kept at extremely low temperatures or high pressures. But the University o

New light-emitting transistor could revolutionize electronics industry

Put the inventor of the light-emitting diode and the maker of the world’s fastest transistor together in a research laboratory and what kinds of bright ideas might surface? One answer is a light-emitting transistor that could revolutionize the electronics industry.

Professors Nick Holonyak Jr. and Milton Feng at the University of Illinois at Urbana-Champaign have uncovered a light-emitting transistor that could make the transistor the fundamental element in optoelectronics as well as in elec

Tiny nanotube antennas may yield better signals in cell phones, televisions

In the future, your cell phone calls and television pictures could become a lot clearer thanks to tiny antennas thousands of times smaller than the width of a human hair. At least that’s the speculation of a University of Southern California researcher who has been investigating nanotube transistors.

The USC scientist, Bart Kosko, Ph.D., a professor in the school’s Electrical Engineering Department, led a study that has demonstrated for the first time that minuscule antennas, in t

Wind energy not limited by technical barriers

Dutch research has demonstrated that there are no technical barriers to wind energy generating a significant part of the electricity supply. With the appropriate technical measures, possible problems in the electricity grid can be taken care of properly.

Researcher Han Slootweg developed simulation models, which demonstrate how wind energy affects the behaviour of electricity grids in concrete situations. These simulation models can also be used to establish the precise nature and size of a

Does wind power have a chance? Four analyses from Lund Institute of Technology

Wind power is the most rapidly growing form of energy in the world today. European wind power accounts for the greatest share, with Denmark, Germany, and Spain as leading countries. In Denmark, for example, wind power provides roughly 12 percent of production of electricity. In Sweden, too, wind power has increased, although to a more limited extent. Between 1996 and 2003 the number of plants doubled from 300 to 631, while annual production trebled from 0.15 to about 0.5 TWh. However, wind accounts f
