A research team from Georgia Tech and ExxonMobil has demonstrated a new carbon-based molecular sieve membrane that could dramatically reduce the energy required to separate a class of hydrocarbon molecules known as alkyl aromatics.
Baratunde Cola would like to put sand into your computer. Not beach sand, but silicon dioxide nanoparticles coated with a high dielectric constant polymer to inexpensively provide improved cooling for increasingly power-hungry electronic devices.
A nanoparticle commonly used in food, cosmetics, sunscreen, and other products can have subtle effects on the activity of genes expressing enzymes that address oxidative stress inside at least two types of living cells.
Fabrics that can generate electricity from physical movement have been in the works for years. Now researchers have taken the next step, developing a fabric that can simultaneously harvest energy from both sunshine and motion.
A new wrinkle on an old technology — solid-state thermophotovoltaics (TPV) — could provide a high-efficiency alternative for directly converting high-temperature heat from concentrated solar thermal to utility-scale electricity.
