A single advanced building control now in development could slash 18 percent – tens of thousands of dollars – off the overall annual energy bill of the average large office building, with no loss of comfort, according to a report by researchers at the Department of Energy's Pacific Northwest National Laboratory.

Using Gamma-Valerolactone to Synthesise Cheaper Alternative Fuels
06/17/2013 - 08:59

MIT chemical engineers have devised a cheaper way to synthesize a key biofuel component, which could make its industrial production much more cost-effective. The compound, known as gamma-valerolactone (GVL), is attractive because of its versatility, says Yuriy Román, an assistant professor of chemical engineering and leader of the research team. It has more energy than ethanol and could be used on its own or as an additive to other fuels. GVL could also be useful as a “green” solvent or a building block for creating renewable polymers from sustainable materials.

More efficient "artifical leaf" using solar energy
06/17/2013 - 08:41

Due to the fluctuating availability of solar energy, storage solutions are urgently needed. One option is to use the electrical energy generated inside solar cells to split water by means of electrolysis, in the process yielding hydrogen that can be used for a storable fuel. Researchers at the HZB Institute for Solar Fuels have modified so called superstrate solar cells with their highly efficient architecture in order to obtain hydrogen from water with the help of suitable catalysts. This type of cell works something like an "artificial leaf."

“Popcorn” particle pathways promise better lithium-ion batteries
06/11/2013 - 09:32

Researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate (LiFePO4, or LFP), findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft.

Micro-RNA controls lignin biosynthesis: Could lead to advances in paper and biofuels production
06/11/2013 - 07:03

The research, published online in Proceedings of the National Academy of Sciences the week of June 10, describes how one strand of micro-RNA reduced by more than 20 percent the formation of lignin, which gives wood its strength. Understanding how to reduce lignin at the cellular level could lead to advances in paper and biofuels production, where harsh chemicals and costly treatments are used to remove lignin from wood.

New Filtration Material Could Make Petroleum Refining Cheaper, More Efficient
05/23/2013 - 16:58

A newly synthesized material might provide a dramatically improved method for separating the highest-octane components of gasoline. Measurements at the National Institute of Standards and Technology (NIST) have clarified* why. The research team, which included scientists from NIST and several other universities, has published its findings in the journal Science.
