MIT team testing new SiC nuclear fuel-rod cladding that could lead to safer power plants

Green Car Congress

A team of researchers at MIT is developing and testing a new silicon carbide (SiC) cladding material for nuclear fuel rods that could reduce the risk of hydrogen production by roughly a thousandfold compared to the common zircaloy cladding. SiC is “ very promising, but not at the moment ready for adoption ” by the nuclear industry, he adds.

MIT team discovers new family of materials with best performance yet for oxygen evolution reaction; implications for fuel cells and Li-air batteries

Green Car Congress

MIT researchers have found a new family of highly active catalyst materials that provides the best performance yet in the oxygen evolution reaction (OER) in electrochemical water-splitting—a key requirement for energy storage and delivery systems such as advanced fuel cells and lithium-air batteries. Grimaud et al.

ORNL finding on surface properties of complex oxides films could lead to better batteries and catalysts

Green Car Congress

The surprising proximity of the surface MIT transition temperature of nonstoichiometric films with that of the fully oxygenated bulk suggests that the electronic properties in the surface region are not significantly affected by oxygen deficiency in the bulk. doi: 10.1039/C3NR02343E.

MIT engineers develop process that can treat produced water from gas wells at relatively low cost

Green Car Congress

A new desalination process developed by engineers at MIT could treat produced water—deep water, often heavily laden with salts and minerals—from natural gas wells at relatively low cost. The research is the work of a team including MIT postdoc Prakash Narayan, mechanical engineering professor John H.

Nanocomposite of bio-templated manganese oxide and Pd as high-performance cathode for Li-air batteries

Green Car Congress

Scientists at MIT have built catalyst structures to achieve high Li-O 2 battery performances by forming a nanocomposite of bio-templated manganese oxide nanowires (bio MO nanowires) produced by the M13 bacteriophage virus ( earlier post ) with incorporation of a small weight percent (3-5 wt%) of Pd nanoparticles.
