'Graphene, electrons and the end of 'conventional silicon electronics' A team led by scientists from the University of California have returned to electrical engineering fundamentals with work that will produce a chip combining memory and logic. Only this will overcome what they call the "ultimate limits" of conventional silicon electronics the others are trying to circumvent. Today, you have memory in RAM and logic in the CPU connected by a bus that causes a bottleneck as instructions are relayed.

Bilayer Graphene Works as an Insulator
24-Jan-2012

RIVERSIDE, Calif. - A research team led by physicists at the University of California, Riverside has identified a property of "bilayer graphene" (BLG) that the researchers say is analogous to finding the Higgs boson in particle physics. Graphene, nature's thinnest elastic material, is a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice. Because of graphene's planar and chicken wire-like structure, sheets of it lend themselves well to stacking. BLG is formed when two graphene sheets are stacked in a special manner. Like graphene, BLG has high current-carrying capacity, also known as high electron conductivity. The high current-carrying capacity results from the extremely high velocities that electrons can acquire in a graphene sheet. The physicists report online Jan. 22 in Nature Nanotechnology that in investigating BLG's properties they found that when the number of electrons on the BLG sheet is close to 0, the material becomes insulating (that is, it resists flow of electrical current) - a finding that has implications for the use of graphene as an electronic material in the semiconductor and electronics industries.

NASA Telescopes Help Find Rare Galaxy at Dawn of Time
11-Jan-2012

Astronomers using NASA's Spitzer and Hubble space telescopes have discovered that one of the most distant galaxies known is churning out stars at a shockingly high rate. The blob-shaped galaxy, called GN-108036, is the brightest galaxy found to date at such great distances.

UC Riverside Physicists Discover New Way to Produce Antimatter-containing Atom
14-Jul-2011

New method allows positronium to be produced for the first time at a wide range of temperatures and in a controllable way RIVERSIDE, Calif. - Physicists at the University of California, Riverside report that they have discovered a new way to create positronium, an exotic and short-lived atom that could help answer what happened to antimatter in the universe and why nature favored matter over antimatter at the universe's creation. Positronium is made up of an electron and its antimatter twin, the positron. It has applications in developing more accurate Positron Emission Tomography or PET scans and in fundamental physics research.

Tevatron Experiment Could Send Particle Physicists Back to the Drawing Board
8-Apr-2011

If the existence of a previously unknown particle is confirmed, it would be the first particle that does not fit into the standard model of particle physics, said UC Riverside physics and astronomy professor John Ellison. The standard model of particle physics is a theory of three of the four known fundamental interactions and the elementary particles that take part in these interactions. These particles make up all visible matter in the universe.

The SciCom Interview: Allen Mills
6-Apr-2011

An atomic manipulator dreams of harnessing antimatter to probe the properties of materials and create powerful new gamma ray lasers Interview by Catherine Meyers Allen Mills's career trajectory took a sudden turn when, one day in graduate school at Brandeis University in the 1960s, he tightened the screws too much on one of the few lasers in existence at the time, breaking the glass. Thus compelled to switch labs, Mills joined the only other experimental physics group on campus and began studying positrons.

Could Radiation from Japan Reach The West?
16-Mar-2011

The disaster at a Japan nuclear power plant has many people on the West Coast looking nervously toward the Pacific, wondering if any releases of radioactivity could come here. Ken Barish is one who says no. He's a physics professor at the University of California, Riverside. Barish says it's unlikely that the West Coast would be harmed by radioactivity drifting from Japan. He joined us by phone from his office.

Japan's radioactivity won't jump Pacific, expert says
15-Mar-2011

Jetstream winds blow from Japan to North America at speeds that can approach 200 mph, but even a worst-case disaster at the stricken Japanese nuclear plant is highly unlikely to send any harmful radiation to the West Coast, a Riverside physics professor says. "I see no chance," Professor Ken Barish said Monday from UC Riverside. "Even in Chernobyl, where they had a flawed design, the radiation that was released didn't extend far outside the area."
