Researchers Counteract Biofuel Toxicity in Microbes

Advanced biofuels are highly touted as potential replacements for gasoline, diesel, and jet fuels. Equally touted is the synthesis of these fuels through the use of microbes. However, many of the best candidate compounds for advanced biofuels are toxic to microbes, which presents a “production versus survival” conundrum.

Jewel-Toned Organic Phosphorescent Crystals: A New Class of Light-Emitting Material

Pure organic compounds that glow in jewel tones could potentially lead to cheaper, more efficient, and flexible display screens, among other applications. University of Michigan researcher Jinsang Kim and his colleagues have developed a new class of material that shines with phosphorescence — a property that has previously been seen only in non-organic compounds or organometallics.

Improving the Vanadium Redox Battery

Though considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and its high cost. New research indicates that modifying the battery's electrolyte solution significantly improves its performance - so much so that the upgraded battery could improve the electric grid's reliability and help connect more wind turbines and solar panels to the grid.
