UC Davis, Livermore announce graduate mentorship program awards

Contributed by AJ Cheline Since 1963, UC Davis and Lawrence Livermore National Laboratory (LLNL) scientists and engineers have conducted joint interdisciplinary research that leverage the strengths of both institutions to address a variety of critical societal problems. Over the last …

Making oxygen before life

About one-fifth of the Earth’s atmosphere is oxygen, pumped out by green plants as a result of photosynthesis and used by most living things on the planet to keep our metabolisms running. But before the first photosynthesizing organisms appeared about …

Dust to dust: BICEP2 result on gravitational waves may not be so strong

Earlier this year, physicists celebrated results from the BICEP2 experiment which reported evidence of gravitational waves, a signature of cosmic inflation immediately after the Big Bang. But earlier this week, results from the Planck space telescope cast doubt on the …

Reproducing deep-Earth chemistry

A new pressure cell invented by UC Davis researchers makes it possible to simulate chemical reactions deep in the Earth’s crust. The cell allows researchers to perform nuclear magnetic resonance (NMR) measurements on as little as 10 microliters of liquid …

Modeling of silicon nanoparticles for solar energy

Silicon nanoparticles embedded in a zinc sulfide matrix are a promising material for new types of solar cell. Computational modeling by Stefan Wipperman, Gergely Zimanyi, Francois Gygi and Giulia Galli at UC Davis and colleagues shows how such a material …

Physicists reflect on gravity wave discovery

Contributed by Lloyd Knox, Department of Physics On March 17, the scientific world was shaken by a dramatic announcement: Astronomers reported what many consider to be the “smoking gun” of a theorized stage in the very early evolution of the …

New materials microscope is a first in the U.S.

Researchers at UC Davis will soon have a new and very special tool to examine the structure and composition of materials at an atomic scale. The new Focused Ion Beam microscope, or dual-beam FIB, now being installed in the College …

Under pressure: new insights in superconductors

Recent work on a superconducting material first discovered at UC Davis is helping reveal the behavior of “unconventional” superconductors, and that physical pressure has a different type of effect on these materials than chemical doping. The material, cerium cobalt indium-5 …
