Researchers report first direct observation of anionic redox in a lithium-rich battery material

Green Car Congress

This is the mechanism credited with the high capacity of the materials, nearly doubling the energy storage compared to conventional cathodes. Unfortunately, the higher energy densities are plagued with problems associated with the irreversibility of anionic redox. Credit: Carnegie Mellon University and Northeastern University.

New protocol to enhance photosynthetic production of hydrogen from green algae

Green Car Congress

A research group from the University of Turku, Finland, has developed a new protocol to deliver sustained hydrogen photoproduction in green algae under a train of strong white light pulses interrupted by longer dark phases. One of the approaches to achieve sustained H 2 photoproduction in C. —Kosourov et al.

UCR researchers discover new method to dissipate heat in electronic devices; modulating the flow of phonons

Green Car Congress

An international team of scientists led by a researcher at the University of California, Riverside has modified the energy spectrum of acoustic phonons—elemental excitations, also referred to as quasi-particles, that spread heat through crystalline materials like a wave—by confining them to nanometer-scale semiconductor structures.
