Green diesel: New process makes liquid transportation fuel from plants
University of Wisconsin-Madison College of Engineering researchers have discovered a new way to make a diesel-like liquid fuel from carbohydrates commonly found in plants.
Reporting in the June 3 issue of the Journal Science, Steenbock Professor James Dumesic and colleagues detail a four-phase catalytic reactor in which corn and other biomass-derived carbohydrates can be converted to sulfur-free liquid alkanes resulting in an ideal additive for diesel transportation fuel. Co-re
New technique aids nano-electronic manufacturing
In the time it takes to read this sentence, your fingernail will have grown one nanometer. That’s one-billionth of a meter and it represents the scale at which electronics must be built if the march toward miniaturization is to continue.
Reporting in the June 3 issue of the Journal Science, an international team of researchers shows how control over materials on this tiny scale can be extended to create complex patterns important in the production of nano-electronics.

ARC solar thermal building product demonstrates energy savings of 48 per cent
Researchers at the Alberta Research Council Inc. (ARC) have completed a pilot study identifying a more efficient technology to insulate homes, reducing space heating costs for homeowners. Researchers proved by combining direct solar collection and heat storage technology with existing structural insulated panel system (SIPS), energy consumption for space heating could be reduced by 48 per cent.
The study focused on measuring energy consumption during a peak energy load perio
Solid-State Lighting Sources Getting More Energy Efficient and Smart
Rensselaer Researchers Detail Potential for Smart Lighting in Science
“Smart” solid-state light sources now being developed not only have the potential to provide significant energy savings, but also offer new opportunities for applications that go well beyond the lighting provided by conventional incandescent and fluorescent sources, according to E. Fred Schubert and Jong Kyu Kim of Rensselaer Polytechnic Institute.

Engineers develop low-cost, highly sensitive underwater listening device
Ocean-going acoustic sensor array to aid in national security, ocean research efforts
Jason Holmes, a mechanical engineering graduate student at Boston University and guest researcher at Woods Hole Oceanographic Institute, has devised a low-cost, highly sensitive array of underwater ears that is perking up interest in both homeland security and ocean research circles. Holmes’ device — an underwater hydrophone array designed to be towed by a small, autonomous submarine — c
