Liquid-like copper ion material aids conversion of heat to electricity

March 13, 2012 4:32 am | News | Comments

Scientists from the Chinese Academy of Science's Shanghai Institute of Ceramics, in collaboration with scientists from Brookhaven National Laboratory, the University of Michigan, and the California Institute of Technology, have identified a new class of high-performance thermoelectric materials. In their study, liquid-like copper ions carry electric current around a solid selenium crystal lattice.

Nerve gas litmus test could sense airborne chemical weapons

March 12, 2012 9:21 am | News | Comments

Nerve gases are colorless, odorless, tasteless, and deadly. While today's soldiers carry masks and other protective gear, they don't have reliable ways of knowing when they need them in time. That could change, thanks to a new litmus-like paper sensor made at the University of Michigan, which are designed to change color from blue to pink within 30 sec of exposure to trace amounts of nerve gas.

Heart-powered pacemaker could eliminate battery-replacement surgery

March 5, 2012 3:18 am | News | Comments

A new power scheme for cardiac pacemakers turns to an unlikely source: vibrations from heartbeats themselves. Engineering researchers at the University of Michigan designed a device that harvests energy from the reverberation of heartbeats through the chest and converts it to electricity to run a pacemaker or an implanted defibrillator.

Researchers help rethink smartphone design with computational sprinting

February 28, 2012 9:07 am | News | Comments

Computational sprinting is a new approach to smartphone power and cooling that could give users dramatic, brief bursts of computing capability to improve current applications and make new ones possible. Its developers at the University of Pennsylvania and the University of Michigan are pushing mobile chips beyond their sustainable operating limits, much like a sprinter who runs extremely fast for a relatively short distance.

Fastest wind from stellar-mass black hole discovered

February 22, 2012 11:25 am | News | Comments

The fastest wind ever discovered blowing off a disk around a stellar-mass black hole has been observed by a team of astronomers. Using NASA's Chandra X-ray Observatory they clocked the record-breaking super wind at about 20 million mph, or about 3% of the speed of light.

Energy-recycling computer technology goes global

February 21, 2012 6:21 am | News | Comments

An energy-recycling computer circuit born at the University of Michigan will enable a new generation of power-efficient laptop PCs and servers. Advanced Micro Devices (AMD) announced that the company's forthcoming 64-bit processor core, dubbed Piledriver, incorporates the technology.

Research initiative will study best approaches for quantum memories

February 16, 2012 4:49 am | News | Comments
