The U.S. Department of Energy's National Renewable Energy Laboratory recently validated greater than 41 percent efficiency at a concentration of 1,000 suns for tiny cells made by Semprius. The energy conversion efficiency of a solar cell is the percentage of sunlight converted by the cell into electricity. Seed money from DOE, together with the experts at the NREL-based … [Read more...]
Carbon Nanotubes as Conductive Material for Through-Silicon Vias
A research team at Chalmers is working with carbon nanotubes as conductive material for through-silicon vias. Carbon nanotubes are going to be the most reliable of all conductive materials if it is possible to use them on a large scale. This is the opinion of Kjell Jeppsson, a member of the research team. The researchers have demonstrated that two chips can be vertically … [Read more...]
New Method for Enhancing Thermal Conductivity Could Cool Computer Chips
The surprising discovery of a new way to tune and enhance thermal conductivity gives engineers a new tool for managing thermal effects in smart phones and computers, lasers and a number of other powered devices. The finding was made by a group of engineers headed by Deyu Li, associate professor of mechanical engineering at Vanderbilt University. Li and his collaborators … [Read more...]
Dean Receives the Society of Women Engineers’ Highest Honor
Professor Cristina Amon, dean of the University of Toronto’s Faculty of Applied Science & Engineering, has received the 2011 Society of Women Engineers Achievement Award, the highest award given by the Society, for her outstanding contributions to the field of engineering over more than 20 years. Dr. Amon is known for her work in fluid mechanics, heat transfer and … [Read more...]
Facebook to Build Arctic Data Center
Facebook has chosen the Swedish town of Luleaa for its first European data center, and third globally, in large part because of its "suitable climate for environmental cooling (and) clean power resources." The company is expected to pump between three and five billion kronor ($440-734 million) into the data centre, creating 300 new construction jobs for the next few years … [Read more...]
