US Army rolls out a mobile chemical weapons neutralizer

By - September 12, 2013 13 Pictures
The US Department of Defense recently rolled out a system to rapidly deploy chemical weapons disposal facilities that could potentially be used quickly and effectively on foreign shores in the near future. The Field Deployable Hydrolysis System (FDHS) developed at the US Army's Edgewood Chemical and Biological Center in Maryland is a mobile system designed to destroy chemical warfare agents in bulk. The FDHS neutralizes chemical agents by mixing them with water and other reagents like sodium hydroxide and sodium hypochlorite and then heating them to produce compounds that are "not usable as weapons." This heating and mixing process to facilitate chemical reactions purportedly has destruction efficiency of 99.9 percent. Read More

New thin film increases efficiency of stacked solar cells

By - September 11, 2013 1 Picture
Researchers at North Carolina State University have developed a new system for strengthening the connections between stacked solar cells which could improve the overall efficiency of concentrated photovoltaic technology and reduce the cost of solar energy production. The hardened connections could theoretically enable these cells to operate at concentrations of up to 70,000 suns while minimizing wasted energy. Read More

Pioneer launches NavGate HUD for smartphone navigation apps

By - September 5, 2013 2 Pictures
Pioneer has unveiled its augmented reality NavGate HUD (head-up display), that projects information onto vehicle windscreens at a size equivalent to a 30-inch monitor viewed from about three meters out. Using a Digital Light Processing (DLP) projector attached to the vehicle's sun visor, a driver is able to see information displayed on the windscreen just above the horizon. The NavGate HUD works together with the CoPilot and iGO primo smartphone apps to display directional instructions, places of interest, hazards and other relevant information. Read More

Steel bonding agent reduces impact forces of helmet-to-helmet hits

By - September 3, 2013 4 Pictures
One of the most feared football-related injuries is concussion. With the new NFL and NCAA college seasons just about to kick off, fans will be praying that none of their team suffers any serious impact collisions that could end their season or result in memory loss or depression later in life. University of California, Los Angeles (UCLA) biomechanical engineering professor, Vijay Gupta, is testing a special polymer material that when applied to the inside of helmets, can reduce G-force impact by 25 percent.

Kyocera develops wafer-thin piezo film speaker for TVs, PCs, tablets

By - August 31, 2013 7 Pictures
Japan's Kyocera Corporation has combined a piezoelectric actuator with a special resin film to produce a proprietary, piezo film speaker that is considerably thinner and lighter than conventional electromagnetic speakers, while boasting similar audio levels. The Smart Sonic Sound already provides the audio for LG's 55-inch curved-screen OLED TV and the company hopes it will give designers of future TVs, computers and tablets more scope to place speakers on the front face of products, enabling an overall size reduction and expanding design options.

Digital autopsy: Replacing scalpels with scanners

By - August 27, 2013 10 Pictures
By using raw data from Multi Slice Computerized Tomography (MSCT) and processing it through sophisticated software on high performance computer systems, Malaysian entrepreneur Mathavan (Matt) Chandran hopes to largely negate the need to slice open bodies at autopsy. His digital autopsy software exploits the power of existing 2D and 3D imaging and visualization equipment to observe and investigate the human body using high definition imagery. Read More
