Berkeley Researchers Tune Chemical Bonds of Buckyballs

If the chemical bonds that hold together the constituent atoms of a molecule could be tuned to become stronger or weaker, certain chemical properties of that molecule might be controlled to great advantage for applications in energy and catalysis. Berkeley Lab researchers at the Molecular Foundry, in collaboration with researchers from Rice University, were able to accomplish this feat by using an applied voltage and electric current to tune the strength of chemical bonds in fullerene or “buckyball” molecules.

Feedback in Realistic Environments, or FIRE Simulates Galaxy Evolution from the Big Bang

For decades, astrophysicists have encountered a puzzling contradiction: although many galactic-wind models—simulations of how matter is distributed in our universe—predict that the majority of the "normal" matter exists in stars at the center of galaxies, in actuality these stars account for less than 10 percent of the matter in the universe.

Researchers Report Basic Difference Between Cuprates and Pnictides Families of High-Temperature Semiconductors

An article in Nature Physics reveals a fundamental difference between the two most important families of so-called "high-temperature superconductors", those based on copper (the cuprates) and those based on iron (the pnictides).
