Future batteries could use a graphene sponge Researchers at Sweden’s Chalmers University of Technology devised a porous, sponge-like aerogel, made of reduced-graphene oxide, to serve as a freestanding electrode in the battery cell. This utilization has the potential to advance lithium sulfur batteries, which are said to possess a theoretical energy density about five times greater than lithi... » read more

Firefly microstructures in LED light bulbs Pennsylvania State University researchers wanted to improve the energy efficiency of commercial light-emitting diode light bulbs to save even more energy. They found the answer in the lantern surface of fireflies. "LED lightbulbs play a key role in clean energy," said Stuart (Shizhuo) Yin, professor of electrical engineering at Penn State. "Overall... » read more

How To Lower LED Costs
By Mark LaPedus - 17 Jul, 2014 - Comments: 2

The LED market remains hot, particularly in the solid-state lighting segment. In fact, solid-state lighting continues to expand amid a precipitous drop in LED prices. And LEDs are expanding into new fronts, such as automotive and intelligent lighting. The LED boom hasn’t been fun for all parties, however. Amid pressure to reduce their tool costs, LED equipment makers are still in the mids... » read more
