Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have developed a method for coating metal surfaces with an ultrathin film containing nanoparticles — particles measuring billionths of a meter — which renders the metal resistant to corrosion and eliminates the use of toxic chromium for this purpose. The scientists have been awarded U.S. Patent number 7,507,480 for their method and the corrosion-resistant metals made from it. The technology is available for licensing.

Raytheon to upgrade Phalanx tech
The U.S. Navy has contracted Raytheon to provide upgrades on a computer-controlled weapons system that defends naval vessels from enemy threats.
U.S. company Raytheon was contracted by the Navy to support upgrades for the Phalanx Close-In Weapon Systems. Under the $259.9 million deal, Raytheon will overhaul 40 of the sea-based Phalanx variants and 17 Centurion Land-Based systems.

Trialling Hypersonic Flight at Woomera
Next-generation air vehicles with the potential to dramatically reduce inter-continental travel times are now one step closer to reality with the successful completion of preliminary hypersonic flight trials at the Woomera Test Range.
The Minister for Defence Science and Personnel, the Hon. Warren Snowdon MP, today congratulated the Defence Science and Technology Organisation (DSTO) and the US Air Force Research Laboratory (AFRL) on the results of their recent joint hypersonic flight trial.
"Hypersonics is the study of flight exceeding approximately five times the speed of sound, and this trial has successfully tested the flight and mission control systems that will be used in future experiments," Mr Snowdon said.

Island Start for Royal Navy's World-Leading Carrier Comms System
A mock-up of an island superstructure that will house some of the most powerful ship-borne communication systems ever seen is being constructed on the Isle of Wight. Report by Steve Moore.
The launch of HMS Queen Elizabeth - the first of two new aircraft carriers - may be six years away, but work is progressing on a vital part of it deep in the heart of the Isle of Wight. When the vessel puts to sea she will break the mould in many ways, not least in her cost efficiency.
Central to her success - and that of the second carrier HMS Prince of Wales due in service towards the end of the next decade - will be her mission system. The system, which will use 1,740km of fibre optic cable and 14,000 items of equipment, underpins her war-fighting capability. It will support voice and data services needed to effect command and control along with management of aircraft and protection of the ship through sensors and radars.

Ceramic Fuel Cells launches new modular generator product - BlueGen
Ceramic Fuel Cells Limited (ASX/AIM: CFU) today officially launched a new modular generator product.
The new unit – called BlueGen – is a ‘mini power station’ for homes and other buildings. It produces low emission electricity and hot water, reducing greenhouse gas emissions and saving on home energy bills. About the size of a dishwasher, the BlueGen unit converts natural gas to electricity and heat via ceramic fuel cells.
The Company plans to make the BlueGen product available in Victoria from early 2010. The Company is in discussions with potential local manufacturing partners. The Company is also in discussions with potential purchasers of the BlueGen product in other markets including Europe and North America.

Compact Discs Enter the Fifth Dimension
Better clear a shelf in your basement for that high-end Blu-ray DVD player you just bought. Researchers report that they can boost the amount of data stored on a disc 10,000-fold by using gold nanoparticles. If commercialized, the technology could allow a single disc to hold as many as 300 movies or 250,000 songs.
Today's CDs and DVDs store data as a string of pits burned into a narrow spiral track in plastic discs. Although less of a commercial success, holograms boost data-storage capacities by storing data in three dimensions. In an effort to kick things up a notch, researchers led by Min Gu, an optoelectronics expert at Swinburne University of Technology in Hawthorn, Australia, added two additional dimensions: the color of light used to write and read the data and the light's polarization, or the direction of its electric field.

SUV nuke detector will avert covert attack, company claims
A turbo-charged engine, 21-inch wheels, Bluetooth, and 600-watt THX speakers are fine, but for the SUV owner who desires everything, how about a Mobile Nuclear Radiation Detection System?
Raytheon is offering the Sports Utility Vehicle-Based Radiation Detection System, which uses advanced spectroscopic technology to detect and identify nuclear radiation, whether sitting put or on the move.
