System Bits: April 30


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

Power/Performance Bits: July 22


Lasers to replace quartz in electronics? While nearly all electronics today require devices called oscillators that create precise frequencies, future high-end navigation systems, radar systems, and even possibly tomorrow's consumer electronics will require references beyond the performance of quartz, according to researchers at Caltech. In fact, these researchers have developed a method to... » read more
