Scientists from SLAC National Accelerator Laboratory, Stanford University, and Germany have figured out a key part of the industrial process for making methanol. It’s an important step toward improving the process—and eventually realizing the goal of turning a potent greenhouse gas, carbon dioxide, into fuel.

A
detailed description of development of the first practical device that
mimics the process of photosynthesis has recently been published in an
American Chemical Society journal. Unlike earlier devices, which used
costly ingredients, the new device is made from inexpensive materials
and employs low-cost engineering and manufacturing processes.

Silicon
germanium (SiGe) has been valued for its performance in
high-temperature thermoelectric applications, but its low-temperature
performance and high cost have prevented broader applications. By
altering the design of bulk SiGe with a process borrowed from the
thin-film semiconductor industry, however, researchers have
substantially increased its electrical conductivity.

One
of the few people to know the various components of the first atomic
bombs, George Cowan would become one of the leading nuclear researchers
in the country and a fixture at Los Alamos National Laboratory for
nearly 40 years. Still working with nonprofit science institute he
helped found, he died Friday as the result of a fall at his home.

Biotechnologists
have recently found a way to control a heat-loving microbe with a
temperature switch by inserting a gene from another organism. The
engineered microbe can be coaxed to use that gene to make a new product,
such as biofuel, by simply lowering the temperature.

Nuclear
physicists at Michigan State University recently witnessed an atomic
nucleus do something that nobody had ever seen one do before—emit two
neutrons at the same time. The experiment revealed a brand new form of
nuclear emission, dineutron decay.

Methane
hydrates, which can freeze upon contact with cold water in the deep
ocean, are a chronic problem for deep-sea oil and gas wells, frequently
blocking flow. Researchers have developed a hydrate-phobic coating that
reduces hydrate sticking to just a quarter of previous levels.

Sarah Phillips wants to join a select few individual who can claim to be the first to see a new state of matter. A recipient of a grant at Thomas Jefferson National Accelerator Facility, she is building a piece of equipment to find a predicted, but never-before-seen state of matter called true muonium. It is a rare atom made from two muon particles, which are similar to electrons.

In
prototypes of the lithium-sulfur battery, lithium ions are exchanged
between lithium- and sulfur-carbon electrodes. The sulfur is an
excellent energy storage material due to its low weight. At the same
time, sulfur is a poor conductor, so researchers have a devised a way to
greatly improve conductivity using a porous network of carbon
nanoparticles.

Researchers
at the Massachusetts Institute of Technology have combined gold
nanoparticles with copper nanoparticles to form hybrid nanoparticles.
Transformed into a powder they can catalyze a carbon dioxide reduction
that uses less energy than previous methods and may help reduce
emissions of greenhouse gases at powerplants and other point sources.
