Halving hydrogen
Like a hungry diner ripping open a dinner roll, a fuel cell catalyst that converts hydrogen into electricity must tear open a hydrogen molecule. Now researchers have captured a view of such a catalyst holding onto the two halves of its hydrogen feast. The view confirms previous hypotheses and provides insight into how to make the catalyst work better for alternative energy uses, researchers reported in Angewandte Chemie International Edition.

First size-based chromatography technique for the study of living cells
Using nanodot technology, Berkeley Lab researchers demonstrated the first size-based form of chromatography for studying the membranes of living cells. This unique physical approach to probing cellular membrane structures reveals critical information that can't be obtained through conventional microscopy.

NREL unlocking secrets of new solar material
A new solar material that has the same crystal structure as a mineral first found in the Ural Mountains in 1839 is shooting up the efficiency charts faster than almost anything researchers have seen before -- and it is generating optimism that a less expensive way of using sunlight to generate electricity may be in our planet's future.

Scientists successfully use krypton to accurately date ancient Antarctic ice
A team of scientists has successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating -- a new technique that may allow them to locate and date ice that is more than a million years old. This will allow them to reconstruct the climate much farther back into Earth's history and potentially understand the mechanisms that have triggered the planet to shift into and out of ice ages.

Study casts doubt on climate benefit of biofuels from corn residue
Biofuels made from corn stover -- stalks, leaves and cobs that remain after harvest -- appear to emit more carbon dioxide over their life cycle than federal standards allow, according to research led by Adam Liska, assistant professor of biological engineering at the University of Nebraska-Lincoln.

AltaSim Technologies wins DOE grant for additive manufacturing
AltaSim Technologies will further develop the technologies that drive additive manufacturing -- adding momentum to AweSim, a public-private initiative led by the Ohio Supercomputer Center to boost industrial use of modeling and simulation. Through an award of nearly $150,000 from the US Department of Energy, Columbus, Ohio-based AltaSim plans to create a manufacturing app that will feature the use of 3-D printing to make a solid, three-dimensional object from a digital model.

Surprising material could play role in saving energy
One strategy for addressing the world's energy crisis is to stop wasting so much energy when producing and using it, such as in coal-fired power plants or transportation. Nearly two-thirds of energy input is lost as waste heat. Now Northwestern University scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. This outstanding property could be exploited in solid-state thermoelectric devices, with potentially enormous energy savings.

For cells, internal stress leads to unique shapes
Caltech researchers discover that a cell's unique shape results from an internal tug-of-war: the cell needs to maintain structural integrity while also dynamically responding to the pushes and pulls of mechanical stress.

Significant baseline levels of arsenic found in Ohio soils are due to natural processes
Geologic and soil processes are to blame for significant baseline levels of arsenic in soil throughout Ohio, according to a new study. The findings pose a challenge for regulators, who must determine what levels should trigger action when natural arsenic levels everywhere are above suggested screening standards.

Low-cost, hydrogen-powered forklifts with rapid refueling, zero emissions coming soon
Zero-emission hydrogen fuel cell systems soon could be powering the forklifts used in warehouses and other industrial settings at lower costs and with faster refueling times than ever before, courtesy of a partnership between Sandia National Laboratories and Hawaii Hydrogen Carriers. The goal of the project is to design a solid-state hydrogen storage system that can refuel at low pressure four to five times faster than it takes to charge a battery-powered forklift.

Shiny quantum dots brighten future of solar cells
A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work by Los Alamos National Laboratory researchers in collaboration with scientists from University of Milano-Bicocca, Italy. Their project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.
