ABSTRACT: For the researchers' complete publication ACS NanoLetters, go here. Direct solar-powered production of value-added chemicals from CO2 and H2O, a process that mimics natural photosynthesis, is of fundamental and practical interest. In natural photosynthesis, CO2 is first reduced to common biochemical building blocks using solar energy, which are subsequently used … [Read more...] about Artificial Photosynthesis: Chemical Synthesis Powered by Sunlight 2015-068

V2G-Sim 2014-021
V2G-Sim is a simulation platform incorporating and aggregating individual vehicle powertrain and charging dynamics plus driver usage patterns to systematically address the real-world effects of any number of plug-in electric vehicles (PEVs) on the electricity grid. V2G-Sim can also be used to quantify battery degradation in PEVs from driving or from vehicles delivering grid … [Read more...] about V2G-Sim 2014-021
Dark-Colored Cool Pigments for Materials Exposed to the Sun IB-3039
For the building and automobile industries in need of dark-colored products that can stay cool in the sun, this technology uses fluorescent materials that re-radiate absorbed light rather than converting it all to heat. The Berkeley Lab invention promises a solar reflectance over 0.5 in dark colors — a significant improvement over commercially available … [Read more...] about Dark-Colored Cool Pigments for Materials Exposed to the Sun IB-3039
