Some remarkable types of bacteria have proven themselves capable of "consuming" toxic pollutants, organically diminishing environmental impact in a process called bioremediation. Enzymes within these bacteria can effectively alter the molecular structure of dangerous chemicals, but the underlying mechanisms and keys to future advances often remain unknown. Now, scientists Brookhaven National Laboratory have revealed a possible explanation for the superior function of one pollution-degrading enzyme.

Lawrence Berkeley National Laboratory theorists and experimenters have led in the exploration of the unique properties of topological insulators, where electrons may flow on the surface without resistance and with their spin orientations and directions intimately related. Recent research at beamline 12.0.1 of the Advanced Light Source opens the way to exciting prospects for practical new spintronic devices that exploit control of electron spin as well as charge.

Hydrogen gas offers one of the most promising sustainable energy alternatives to limited fossil fuels. But traditional methods of producing pure hydrogen face significant challenges in unlocking its full potential. Now, scientists at Brookhaven National Laboratory have developed a new electrocatalyst that addresses one of these problems by generating hydrogen gas from water cleanly and with much more affordable materials.

In the search for new materials with improved electrical conductivity, scientists at Brookhaven National Laboratory have found what appears to be a promising candidate. New experiments show that electrons on the surface of this so-called topological insulator are "protected" from two kinds of scattering that can potentially interfere with the flow of electric current, even at relatively "warm" room temperatures, where the flow of electricity was expected to break down.

A new approach to assessing greenhouse gas emissions from
coal, wind, solar, and other energy technologies paints a much more
precise
picture of cradle-to-grave emissions and should help sharpen decisions
on what
new energy projects to build.

By measuring how strongly electrons are bound together to form Cooper pairs in an iron-based superconductor, scientists provide direct evidence supporting theories in which magnetism holds the key to this material’s ability to carry current with no resistance. This research strengthens confidence that this type of theory may one day be used to identify or design new materials with improved properties.

Construction of the $912-million National Synchrotron Light Source II (NSLS-II) at the Brookhaven National Laboratory is more than 70% complete—on schedule and on budget. When operational in 2015, NSLS-II will enable unprecedented studies aimed at designing new materials for efficient energy generation and storage, building better catalysts, and engineering new kinds of electronics and medicines.

At
Brookhaven National Laboratory, a new x-ray microscope is probing the
inner intricacies of materials spanning 25 nm, creating unparalleled
high-resolution 3D images. By integrating unique automatic calibrations,
scientists hope the new transmission X-ray microscope will offer
fundamental advances in many fields.
