Ultrahigh energy cosmic rays reviewed by Prof. Stanev

 September 12, 2011 - The latest issue of Reviews of Modern Physics (RMP) features an article by Prof. Stanev on Ultrahigh energy cosmic rays. An illustration from the article also appears on the front cover of RMP.

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.
