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.

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.

Electrochemical Ultracapacitors Using Graphitic Nanostacks

Applications include cell phones and other portable consumer electronic devices, hybrid electric vehicles, automatic electronic defibrillators, and uninterruptable power supplies. Electrochemical ultracapacitors (ECs) have been developed using graphitic nanostacks as the electrode material. The advantages of this technology will be the reduction of device size due to superior power densities and relative powers compared to traditional activated carbon electrodes. External testing showed that these materials display reduced discharge response times compared to state-of-the-art materials. Such applications are advantageous for pulsed power applications such as burst communications (satellites, cell phones), electromechanical actuators, and battery load leveling in electric vehicles. These carbon nanostructures are highly conductive and offer an ordered mesopore network. These attributes will provide more complete electrolyte wetting, and faster release of stored charge compared to activated carbon.

Large-Strain Transparent Magnetoactive Polymer Nanocomposites

A document discusses polymer nanocomposite superparamagnetic actuators that were prepared by the addition of organically modified superparamagnetic nanoparticles to the polymer matrix. The nanocomposite films exhibited large deformations under a magnetostatic field with a low loading level of 0.1 wt% in a thermoplastic polyurethane elastomer (TPU) matrix. The maximum actuation deformation of the nanocomposite films increased exponentially with increasing nanoparticle concentration.

Tailoring Metal Oxides for Green Technological Applications

Harnessing solar energy can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice ‘sandwich.’ "Metal oxides can be tailored to meet all sorts of needs, which is good news for technological applications, specifically in energy generation and flat screen displays,” said Louis Piper, assistant professor of physics at Binghamton University.
