Tevatron tightens up the race for the Higgs

WITH the Large Hadron Collider still in the repair shop, the race to find the Higgs boson has become a lot tighter, thanks to the older and less powerful - but working - Tevatron collider near Chicago.

Platinum nanocatalyst could aid drugmakers

Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form. Rice University chemists have answered the call this week with a polymer-coated version of gold-platinum nanorods, the first catalysts of their kind that can be used in the organic solvents favored by chemical and drug manufacturers.

Army’s new plastic helmet tops Kevlar ACH

The Army intends to start issuing a new combat helmet made of a special plastic capable, for the first time, of stopping penetration by enemy rifle rounds.

Officials from Product Manager Soldier Protective Equipment plan to buy 200,000 Enhanced Combat Helmets that depend on “ultra-high molecular weight polyethylene” instead of ballistic fibers such as Kevlar and Twaron used in the current Army Combat Helmet.

High-end server chips breaking records

How would you like a single-chip microprocessor with more than four times the performance (on some applications) of Intel's bestCore i7?

Then consider that up to 32 of these chips can be directly connected to form a single server, achieving four times the built-in scalability of Intel's next-generation Nehalem-EX processor.

Raytheon's Gallium Nitride Establishes Radar Technology Standard

Raytheon Company's (NYSE: RTN) innovative gallium nitride (GaN) chips have achieved 1,000 hours of reliable operation, positioning this technology as the standard for next generation radar capability.

GaN technology provides increased reliability and efficiency, resulting in lower prime power consumption and relaxed cooling requirements. Thus, GaN T/R modules provide significantly higher long-pulse radio frequency (RF) power than that of standard gallium arsenide (GaAs) T/R modules.

DARPA Wants Morphing Helicopter Blades

Military lab DARPA has put out a call for rotor blades that could boost payloads by 30 percent and range by 40 percent, as well as reduce sound by 50 percent and vibration by 90 percent compared to the usual fixed rotor blades.

The agency envisions helicopter blades that can morph into different modes for "fuel efficiency" or "high maneuver," as examples. Adaptive technologies could change the diameter, sweep, chord, and tip shape of the blades, as well as other features.

Aerospace Giant Building a Gravity Tractor to Deflect Killer Asteroids

NASA astronauts Edward Lu and Stanley Love first proposed using a robotic spacecraft to nudge space rocks away from Earth using the gentle force of gravity a few years ago. Now a European aerospace giant has begun seriously investigating the concept.

The 11-ton "gravity tractor" would have to launch 15 years before a predicted collision between an asteroid and Earth, according to the BBC. But the company, EADS Astrium, noted that no spacecraft prototype has emerged just yet.

Plasmons create smallest laser - again

Earlier this month researchers from Purdue, Cornell and Norfolk State universities reported demonstration of the smallest laser ever --, consisting of a nanoparticle just 44 nm across. Strictly speaking it was a spaser --, or surface plasmon laser. Now it's the turn of researchers at the University of California at Berkeley. This week in an article in Nature the Berkeley researchers claim to have created the smallest semiconductor laser ever. Their new device can generate light in a space just 5 nm in size.

Hyperspectral imaging gets funding boost

Multispectral imaging technology got a big boost recently when the U.S. House of Representatives approved a funding bill that includes $2.5 million for development of hyperspectral imaging by Headwall Photonics (Fitchburg, MA). The funding is included in the FY10 Department of Defense Appropriations Act, which the House passed on July 30, 2009. The Senate must still approve its appropriations bill and then both chambers will have to approve a reconciled bill before it goes to the president's desk to be signed into law.

Graphene Makes Transistors Tunable

The existence of an energy gap between the conduction and valence electron bands of a semiconductor is what makes it possible for the material to act as a semiconductor. In both single-layer and double-layer graphene [left and middle], the valence and conduction bands are in effect conical and meet at a point, with no band gap. The introduction of an electric field perpendicular to the layers [right] creates an asymmetry, which generates a band gap. Though small, the gap is tunable, creating possibilities for new devices.

After the Transistor, a Leap Into the Microcosm

Dr. Ross, an I.B.M. researcher, is growing a crop of mushroom-shaped silicon nanowires that may one day become a basic building block for a new kind of electronics. Nanowires are just one example, although one of the most promising, of a transformation now taking place in the material sciences as researchers push to create the next generation of switching devices smaller, faster and more powerful than today’s transistors.
