Integrated onto the backs of chips
A new technique for fabricating liquid cooling channels onto the backs of high-performance integrated circuits could allow denser packaging of chips while providing better temperature control and improved reliability.
Developed at the Georgia Institute of Technology, the wafer-level fabrication technique includes polymer pipes that will allow electronic and cooling interconnections to be made simultaneously using automated manufacturing
Commercial products such as laptop computer monitors and solar-powered calculators are constructed from a light-sensitive material with a peculiar problem: When exposed to intense light, it forms defects, reducing the efficiency of the solar cells by 10 to 15 percent.
Scientists have been pondering this flaw since the 1970s, because the material – hydrogenated amorphous silicon, or a-Si:H – has important applications for solar energy generation. A new study reported in the Jun
Dutch energy policy is directed at 17 percent of electricity demand being covered by renewable energy sources by 2020. Martin Junginger has demonstrated that this can be achieved at considerably lower costs than is the case now. He also found that it might be more financially advantageous to realise part of the objective outside of the Netherlands because, for example, more space is available there for wind turbines or because more biomass is available there.
Renewable electricity can
By pairing a sleek new air sampler designed at the University Corporation for Atmospheric Research (UCAR) with a diode laser from SpectraSensors, Inc., researchers have hit on a technology that can capture highly accurate atmospheric water vapor data during routine commercial flights. The data will benefit researchers and forecasters, who need more frequent, accurate measurements at various altitudes worldwide to improve weather forecasts and monitor climate change.

Recycled plastic bottles could one day be used to lubricate your cars engine, according to researchers at Chevron and the University of Kentucky, who in laboratory experiments converted waste plastic into lubricating oil. These polyethylene-derived oils, they say, could help improve fuel economy and reduce the frequency of oil changes.
The pilot study appears in the July 20 issue of the American Chemical Societys peer-reviewed journal Energy & Fuels. ACS is the worl
Demonstrating breakneck signal speed of 10 gigahertz, method uses nanotubes instead of conventional copper wires
UC Irvine scientists in The Henry Samueli School of Engineering have demonstrated for the first time that carbon nanotubes can route electrical signals on a chip faster than traditional copper or aluminum wires, at speeds of up to 10 GHz. The breakthrough could lead to faster and more efficient computers, and improved wireless network and cellular phone systems, addi
