Complex structural dynamics of nanocatalysts revealed in Operando conditions by correlated imaging and spectroscopy probes

Here by a correlated use of synchrotron X-ray absorption spectroscopy and scanning transmission electron microscopy in operando conditions, we quantitatively describe the complex structural dynamics of supported Pt catalysts exhibited during an exemplary catalytic reaction-ethylene hydrogenation.

Kinetics and fracture resistance of lithiated silicon nanostructure pairs controlled by their mechanical interaction

Here, we demonstrate physical and mechanical interactions of swelling Si structures during lithiation using well-defined Si nanopillar pairs. Ex situ SEM and in situ TEM studies reveal that compressive stresses change the reaction kinetics so that preferential lithiation occurs at free surfaces when the pillars are mechanically clamped.

DOE: Hanford vit plant safety culture shows improvement

Improvements have been made in the safety culture at the Hanford vitrification plant, according to a followup assessment conducted by an independent arm of the Department of Energy.

Idaho aquifer decline could hinder radioactive monitoring

(AP) BOISE, Idaho - A continued drop in underground water levels could make it more difficult to monitor the movement of radioactive contamination in an aquifer below an eastern Idaho nuclear facility, scientists say.

Federal, HSU project seeks to improve biomass energy capabilities

In the isolated timberlands east of Big Lagoon, a multimillion-dollar project led by Humboldt State University and the U.S. Department of Energy is working to harness the bountiful biofuel within the forests for use as renewable energy here and abroad.

Iron: A biological element?

Think of an object made of iron: An I-beam, a car frame, a nail. Now imagine that half of the iron in that object owes its existence to bacteria living two and a half billion years ago. That's the upshot of a new study. Its findings have meaning for fields as diverse as mining and the search for life in space. (http://dx.doi.org/10.1073/pnas.1505515112)

Opening a new route to photonics

A new route to ultrahigh density, ultracompact integrated photonic circuitry has been discovered by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. (http://dx.doi.org/10.1038/ncomms8565)

Orange is the new red

In a study led by Cheryl Kerfeld, a structural biologist with Berkeley Lab's Physical Biosciences Division, the research team found that in cyanobacteria the energy-quenching mechanism is triggered by an unprecedented, large-scale movement (relatively speaking) from one location to another of the carotenoid pigment within a critical light-sensitive protein called the Orange Carotenoid Protein (OCP).

Eye protection

A person's eyesight is often taken for granted. It's easy for employers and employees to overlook the dangers to our eyes that we encounter every day. Unfortunately, eye injuries in the workplace are very common.

The workplace perks that are in - and out

Find the thought of workplace fitness contests a little awkward, or the idea of a company-provided "health and lifestyle coach" kind of eerie? Too bad. In its latest annual survey of what's in and what's out in the world of employee perks, the Society of Human Resource Management found that wellness benefits are only increasing in prevalence.

Nice urges employers to promote healthy working environments

Healthcare watchdog the National Institute for Health and Care Excellence (Nice) has published guidelines urging employers to do more to address the effect that poor working environments can have on employees' lives

Congress slow to reauthorize critical conservation fund

In about 100 days the federal Land and Water Conservation Fund will expire unless Congress moves quickly to reauthorize the program. ... "In Washington state, the LWCF has helped preserve places like the Columbia River Gorge, Lake Chelan, Mount Rainier and Olympic National Parks, and it has improved management of our public lands," Senator Maria Cantwell, ranking member of the U.S. Senate Energy and Natural Resources Committee, said in a media release.
