Coaxial Nanocable Could Aid in Energy Storage

Researchers at Rice University have created a coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable was produced with techniques pioneered in the burgeoning graphene research field and could be used to build next-generation energy-storage systems.

New Materials May Cut Energy Costs for Carbon Capture

A study of over four million absorbent minerals has determined that industrial minerals called zeolites could help electricity producers slash as much as 30 percent of the parasitic energy costs associated with removing carbon dioxide from power plant emissions. The research was done by scientists at Rice University, UC Berkeley, Lawrence Berkeley National Laboratory, and the Electric Power Research Institute.

Sensor System Spurs Biofuel Production

University of California, Berkeley researchers have developed a genetic sensor that enables bacteria to adjust their gene expression in response to varying levels of key intermediates for making biodiesel. As a result, the microbes produced three times as much fuel. The sensor-regulator system could eventually make advanced biofuels cheaper.

Copper-Gold Nanoparticles Efficiently Convert Carbon Dioxide

Copper is one of the few metals that can turn carbon dioxide into hydrocarbon fuels with relatively little energy, but it is temperamental and easily oxidized. MIT researchers have engineered nanoparticles of copper mixed with gold - which is resistant to corrosion and oxidation - making the copper much more stable. They coated electrodes with the hybrid nanoparticles and found that much less energy was needed for conversion.

Boosting Nanowires for Better Batteries and Solar Cells

Stanford University engineers have found a novel method for "decorating" nanowires with chains of tiny particles to increase their electrical and catalytic performance. The technique is simpler and faster than earlier methods and could lead to better lithium-ion batteries, more efficient thin-film solar cells, and improved catalysts that yield new synthetic fuels.
