MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

Researchers at MIT have identified , quantified, and modeled a major reason for the poor performance of electroreduction processes to convert CO 2 to fuel or other useful chemicals. The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. —Soto et al.

MIT Looks Ahead to Hydrogen’s Aviation Future

Cars That Think

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. As investment in hydrogen-powered flight expands , airports and air carriers today are realizing that it’s not enough to retrofit or design new planes for hydrogen power. asks Professor R. The first challenge is hydrogen production.

MIT-led team devises new approach to designing solid ion conductors; implications for high-energy solid-state batteries

Green Car Congress

Researchers led by a team from MIT, with colleagues from Oak Ridge National Laboratory (ORNL), BMW Group, and Tokyo Institute of Technology have developed a fundamentally new approach to alter ion mobility and stability against oxidation of lithium ion conductors—a key component of rechargeable batteries—using lattice dynamics.

MIT, NASA, ORNL team developing “neutron microscope”

Green Car Congress

Researchers at MIT, working with partners at NASA and Oak Ridge National Laboratory, have developed a new concept for a “neutron microscope”—a compact focusing-mirror-based small-angle neutron scattering instrument—that would use neutrons instead of beams of light or electrons to create high-resolution images. Earlier post.)

Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems

Green Car Congress

Now, a study at MIT has for the first time analyzed and quantified how bubbles form on these porous electrodes. The work is described in the journal Joule , in a paper by MIT visiting scholar Ryuichi Iwata, graduate student Lenan Zhang, professors Evelyn Wang and Betar Gallant, and three others. —Beta Gallant.

MIT/Stanford team develops battery technology for the conversion of low-grade waste heat to power; TREC

Green Car Congress

Researchers at MIT and Stanford University have developed new battery technology for the conversion of low-temperature waste heat into electricity in cases where temperature differences are less than 100 degrees Celsius. A design for heat recuperation in TREC with heat exchangers (HXs). It is a very promising technology.

LLNL/MIT team creates ultralight, ultrastiff metamaterials; possible applications for automotive and aerospace

Green Car Congress

The new materials designed with additive manufacturing techniques exhibit high stiffness and low density, occupying a previously unpopulated area (upper left) of the Ashby material selection chart for Young’s modulus (stiffness) vs. density. The research team’s findings are published in an article in the journal Science. Zheng et al.
