Using an ultrahigh-precision microscopy technique, Berkeley Lab
researchers have uncovered a way to improve the collective catalytic activity of enzyme cocktails on cellulosic biomass, boosting the yields of sugars for the production of advanced biofuels.
Department of Energy Renews Joint BioEnergy Institute for Another Five Years
The Department of Energy has renewed funding for the Joint BioEnergy Institute (JBEI) for another five years. JBEI is a multi-institutional partnership for advanced biofuels research led by the Lawrence Berkeley National Laboratory (Berkeley Lab).
Building the Massive Simulation Sets Essential to Planck Results
The Planck collaboration will soon release its first cosmological results from trillions of measurements of the cosmic microwave background. The results owe much to Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC), including tens of millions of hours of massively parallel processing, plus the expertise of physicists and computational scientists in the Computational Cosmology Center (C3) who generated a quarter of a million simulated maps of the Planck sky, essential to the analysis.
Surprising Control over Photoelectrons from a Topological Insulator
Electrons flowing swiftly across the surface of topological insulators (TIs) are “spin polarized,” their spin and momentum locked. This new way to control electron distribution in spintronic devices makes TIs a hot topic in materials science. Now Berkeley Lab scientists have discovered more surprises: contrary to assumptions, the spin polarization of photoemitted electrons from a topological insulator is wholly determined in three dimensions by the polarization of the incident light beam.
