Making Frequency-Hopping Radios Practical
May 15, 2013 2:45 pm | by Larry Hardesty, MIT | News | CommentsThe way in which radio spectrum is currently allocated to different wireless technologies can lead to gross inefficiencies. In some regions, for instance, the frequencies used by cellphones can be desperately congested, while large swaths of the broadcast-television spectrum stand idle.
HotSpot Episode 12: 3D Microbatteries
May 15, 2013 2:40 pm | by Eric Sorensen, Multimedia Coordinator | Videos | CommentsThis week on WDD's HotSpot, a netbook-like combo that uses a smartphone for its computing power, new microbatteries for a balance between energy and density, satellites that listen in on ADS, and a sound camera that shows the location of troublesome noises in machinery.
New Uses for Tiny Carbon Nanotubes
May 15, 2013 2:38 pm | by University of California - Riverside | News | CommentsThe atom-sized world of carbon nanotubes holds great promise for a future demanding smaller and faster electronic components. Nanotubes are stronger than steel and smaller than any element of silicon-based electronics—the ubiquitous component of today's electrical devices—and have better conductivity, which means they can potentially process information faster while using less energy.
Solutions for Energy-Efficient Repairs in Moscow
May 15, 2013 2:36 pm | by Satu Paiho, Senior Scientist | News | CommentsThere are many old and decrepit residential buildings in Moscow in need of refurbishment. VTT Technical Research Centre of Finland has developed three repair concepts for improv-ing the energy efficiency of both buildings and entire residential districts while also reducing their environmental impact.
MEMS Mass Flow Sensor

The sensor uses the proprietary Omron mass flow MEMs chip, however, the internal flow path has been redesigned to produce a low flow, high velocity/high impedance sensor that will output a differential pressure.
Friction in the Nano-World
May 15, 2013 2:33 pm | by Prof. Dr. Thorsten Hugel, Technische Universitaet Muenchen | News | CommentsFriction is an omnipresent but often annoying physical phänomenon: It causes wear and energy loss in machines as well as in our joints. In search of low-friction components for ever smaller components, a team of physicists led by the professors Thorsten Hugel and Alexander Holleitner now discovered a previously unknown type of friction that they call “desorption stick.”
Students in Ghana Launch Mini-Satellite
May 15, 2013 2:33 pm | by Robbie Corey-Boulet, Associated Press | News | CommentsTheir project might not sound like much: The college students on Wednesday launched a tiny model of a satellite the size of a Coke can on a big yellow balloon. It went aloft to a height of 165 meters (yards) and then came back down attached to a red parachute.
Encoders and Inclinometers with J1939 Interface
May 15, 2013 2:33 pm | by PD&D Staff | Fraba Inc. | Product Releases | CommentsPOSITAL's (Hamilton, NJ) versatile inclinometers and absolute rotary encoders are now available with J1939 communications interfaces. POSITAL's versatile inclinometers and absolute rotary encoders are now available with J1939 communications interfaces.
Ultraresponsive Magnetic Nanoscavengers Could Usher In Next Generation Water Purification
May 15, 2013 2:30 pm | by Andrew Myers, Stanford Engineering | News | CommentsAmong its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Yet other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using nanoscale particles of these active materials. Engineers call them nanoscavengers.
