Electronic Noses Detect Chemical Warfare Gases

Researchers at the Polytechnic University of Valencia have developed a prototype electronic "nose" for the detection of chemical warfare gases, mainly nerve gas, such as Sarin, Soman, and Tabun.

Prosthetic Arm Controlled by Imagining a Motion

Controlling a prosthetic arm by just imagining a motion may be possible through the work of Mexican scientists at the Centre for Research and Advanced Studies. First, it is necessary to know if there is a memory pattern in the amputee's brain in order to know how the arm moved. The pattern is then translated to instructions for the prosthesis.

New Laser Technology to Make 2020 Mission to Mars

NASA announced recently that laser technology originally developed at Los Alamos National Laboratory has been selected for its new Mars mission in 2020. SuperCam, which builds upon the successful capabilities demonstrated aboard the Curiosity Rover during NASA’s current Mars Mission, will allow researchers to sample rocks and other targets from a distance using a laser.

New Circuits Can Function at Temperatures Above 650°F

Engineering researchers at the University of Arkansas have designed integrated circuits that can survive at temperatures greater than 350 degrees Celsius — or roughly 660 degrees Fahrenheit. Their work, funded by the National Science Foundation, will improve the functioning of processors, drivers, controllers and other analog and digital circuits used in power electronics, automobiles and aerospace equipment, all of which must perform at high and often extreme temperatures.

Agile Aperture Antenna Tested on Aircraft to Maintain Satellite Connection

Two of Georgia Tech's software-defined, electronically reconfigurable Agile Aperture Antennas (A3) were demonstrated in an aircraft during flight tests. The low-power devices can change beam directions in a thousandth of a second. One device, looking up, maintained a satellite data connection as the aircraft changed headings, banked and rolled, while the other antenna looked down to track electromagnetic emitters on the ground.

Nano-Pixels Promise Flexible, High-Res Displays

A new discovery will make it possible to create pixels just a few hundred nanometers across. The "nano-pixels" could pave the way for extremely high-resolution and low-energy thin, flexible displays for applications such as 'smart' glasses, synthetic retinas, and foldable screens.Oxford University scientists explored the link between the electrical and optical properties of phase change materials (materials that can change from an amorphous to a crystalline state). By sandwiching a seven=nanometer-thick layer of a phase change material (GST) between two layers of a transparent electrode, the team found that they could use a tiny current to 'draw' images within the sandwich "stack."Initially still images were created using an atomic force microscope, but the researchers went on to demonstrate that such tiny "stacks" can be turned into prototype pixel-like devices. These 'nano-pixels' – just 300 by 300 nanometers in size – can be electrically switched 'on and off' at will, creating the colored dots that would form the building blocks of an extremely high-resolution display technology.SourceAlso: Learn about Slot-Sampled Optical PPM Demodulation.
