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.

New 3-step process for conversion of kraft lignin from black liquor into green diesel

Green Car Congress

In a paper describing the kraft recovery process, Honghi Tran from the University of Toronto and Esa K. Pöyry Forest Industry Oy in Finland, noted that: The magnitude of the recovery process is often not fully appreciated. For every ton of pulp produced, the kraft pulping process produces about 10 tons of weak black liquor or about 1.5
