Structure of "oil-eating" enzyme opens door to bioengineered catalysts
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds—the first and most challenging step in turning simple hydrocarbons.....»»
X-ray imagery of vibrating diamond opens avenues for quantum sensing
When it comes to materials for quantum sensors, diamond is the best game in town, says Cornell University professor Gregory Fuchs. Now he and a team of scientists have upped diamond's game by generating exquisite imagery of diamond undergoing microsc.....»»
Tundra vegetation to grow taller, greener through 2100, study finds
Warming global climate is changing the vegetation structure of forests in the far north. It's a trend that will continue at least through the end of this century, according to NASA researchers. The change in forest structure could absorb more of the.....»»
Researchers reveal atomic-scale details of catalysts" active sites
The chemical and energy industries depend upon catalysts to drive the reactions used to create their products. Many important reactions use heterogeneous catalysts—meaning that the catalysts are in a different phase of matter than the substances th.....»»
Novel machine learning-based cluster analysis method that leverages target material property
In materials science, substances are often classified based on defining factors such as their elemental composition or crystalline structure. This classification is crucial for advances in materials discovery, as it allows researchers to identify pro.....»»
