Lignin-Feasting Microbe Holds Promise for Biofuels

Nature designed lignin, the tough woody polymer in the walls of plant cells, to bind and protect the cellulose sugars that plants use for energy. For this reason, lignin is a major challenge for those who would extract those same plant sugars and use them to make advanced biofuels. As part of their search for […]

Alaskan North Slope Climate: Hard Data from a Hard Place

Mark Ivey—manager for Sandia of the Department of Energy’s Atmospheric Radiation Measurement (ARM) climate research facility at Barrow—is waiting for the automated release of a weather balloon … [which] measures the Arctic atmosphere’s temperature, humidity, and wind speeds at a rapid succession of altitudes as it rises. The data gathering is part of an ongoing […]

Wong, and EFRC scientists François Léonard, Qiming Li, and George T. Wang, present a theoretical  and computational study of the electronic properties of core/shell nanowires.  They […]

Jeff Tsao participates in “Energy Efficiency and the Rebound Effect” Workshop

On August 15, 2011, in News, Solid-State Lighting

June 27-28, 2011 [singlepic id=979 w=320 h=240 float=right] The rebound (or take-back) effect) is the term in energy economics used to describe the effectin which increases in energy efficiency do not necessarily lead to simple 1:1 decreases in energy consumption, but instead are “taken back” in the form of higher consumption of the goods and […]
