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.

Researchers advance concept of “4-D” printing technology using shape memory polymer fibers

Green Car Congress

Researchers at the University of Colorado Boulder and Singapore University of Technology and Design have added a “fourth dimension” to additive manufacturing technology, opening up possibilities for the creation and use of adaptive, composite materials in manufacturing, packaging and biomedical applications. A team led by H. Ge, Qi and Qi, H.

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. —Snijders et al. —Paul Snijders. doi: 10.1039/C3NR02343E.

This Fusion Reactor Is Held Together With Tape

Cars That Think

Commonwealth Fusion Systems says this spool of high-temperature superconducting tape is key to the startup’s smaller, cheaper tokamak design. Gretchen Ertl/CFS/MIT Plasma Science and Fusion Center In September 2021, Commonwealth Fusion Systems tested the first of its reactor’s D-shaped toroidal field magnets.

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.

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.

How Remote Sensing Technologies Increase Food Production

Cars That Think

I was interested in the design and operation of airplanes and spacecraft.” People were really interested in clean air and clean water, so I decided there would always be interest in the environment,” Crawford says. Although it was designed for a life of 18 months, the mission operated successfully for 16 years.
