CO2 Higher Today Than Last 2.1 Million Years : Study Offers Detailed Look at Past Greenhouse Gas Levels

Researchers Putting a Freeze on Oscillator Vibrations


University of Oregon work could boost quantum information processing, allow more precise measurements. Hailin Wang, a member of the Oregon Center for Optics and a professor in the UO physics department, and his doctoral student Young-Shin Park performed the research under grants from the National Science Foundation and Army Research Laboratory through the Oregon.

Newly Uncovered Enzymes Turn Corn Plant Waste into Biofuel


CORN STOVER: The remnants (or 'stover') of corn after it's harvested can be a good source of biofuel, especially when combined with the right enzymes.

Protein that Triggers Plant Cell Division Revealed by Researchers

Advance in Understanding Cellulose Synthesis

Exploring High-Temperature Superconductivity and the Pseudogap


Using both scanning tunneling microscopy (STM) and angle-resolved photo-electron spectroscopy (ARPES) gives researchers a more complete understanding of high-temperature superconducting materials. STM can show actual atoms on the material's surface. ARPES uses the photoelectric effect by aiming a beam of light (photons) at the material's surface. The photons excite atoms in the material, causing them to eject electrons, which are then captured by a detector. The momentum (speed and direction) of the ejected electrons give researchers information about the momentum of electrons inside the material.
