Power grid buffer? New production process for NiO/Ni nanocomposite electrodes for supercapacitors

June 8, 2011 - Conversion to renewable energy sources like wind and sun is only a question of time. Because wind and solar radiation vary in strength, the increase in renewable energy sources will cause significant fluctuations in the power grid. These must be absorbed by energy storage systems. This need could be fulfilled by a device known as a supercapacitor.

Burned-out star offers Whole Earth Telescope team insights into sun's future

June 6, 2011 - Judi Provencal, the University of Delaware astronomer, has been busy staffing the command center for a star watch of epic proportions, the latest observing run of the Whole Earth Telescope (WET). This global collaboration of observatories collects asteroseismic data—information on stellar waves that pass through hot stars in the cosmos like earthquakes pass through Earth—to determine what’s going on inside these exploding balls of hydrogen and helium gas.

Sharp turn ahead for light beams


May 27, 2011 - Over the last decade, the field of optics has been turned on its head by artificial materials that bend light in ways that no natural material can. In a new development, theorists have shown that a carefully designed array of tiny rods can deflect a light beam at a sharp angle.

Quantum calculations can make atomic clocks of the future far more accurate

May 6, 2011 - New calculations of how atoms swell when they’re warmed up can help make the next generation of atomic clocks 10 times more precise. The current precision champ, the quantum-logic clock developed

UD VERITAS group discovers gamma-rays from the remnant of Tycho's Supernova

March 15, 2011 - Using the VERITAS gamma-ray telescope array in Arizona, graduate student Dana Saxon has detected high energy gamma-ray emission from the expanding remnant of a  supernova explosion which was observed by the Danish astronomer Tycho Brahe in 1572.
