Engineered “Sand” May Help Cool Electronic Devices

A thermal probe tests heat conductance in a sample of silicon dioxide nanoparticles. The material could potentially conduct heat at an efficiency higher than that of conventional materials. (Credit: Rob Felt, Georgia Tech) Baratunde Cola would like to put sand into your computer. Not beach sand, but silicon dioxide nanoparticles coated with a high dielectric constant polymer to inexpensively provide improved cooling for increasingly power-hungry electronic devices.

Researcher Creates System to Control Robots With the Brain

Skull cap outfitted with 128 electrodes wired to a computer to record brain activity. A researcher at Arizona State University has discovered how to control multiple robotic drones using the human brain. A controller wears a skull cap outfitted with 128 electrodes wired to a computer. The device records electrical brain activity. If the controller moves a hand or thinks of something, certain areas light up.

Advances in Vision-Aided Navigation Keep Soldiers on Track

Eric Bickford, U.S. Army CERDEC engineer, compares the current prototype vision-aided navigation system with a 3-D rendition of a planned smaller, more soldier-wearable system. CERDEC engineers are analyzing the systems as a possible emerging and alternative navigation technologies for future combat operations. (Photo: U.S. Army RDECOM) The Army Materiel Command’s Communications-Electronics Research, Development and Engineering Center, or CERDEC, is using miniature cameras to create vision-aided navigation capabilities in GPS-denied situations.

Gas Sensor Monitors Pollution from Power Plants and Roads 

Experimental setup for the ultrasensitive real-time trace gas sensor. (Photo: Adelphi University) A research team from Adelphi University in New developed a new device that can detect ultra-low concentrations of gases like nitrogen dioxide accurately and nearly instantaneously. The device works even when experiencing small vibrations, which is important if the instrument is deployed in the field.
