Improving battery performance with sand Researchers at the University of California, Riverside’s Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times using sand as the key material. The researchers, who said this is a low cost, non-toxic, environmentally-friendly way to produce high performance lithium ion battery a... » read more

IoT, A Market And Technology Set To Explode
By Zach Shelby - 10 Jul, 2014 - Comments: 0

While a fully-connected Internet of Things (IoT) world is still away off, an increasing number of devices are being built that can communicate with each other through wireless connections such as WiFi, Bluetooth, 6LoWPAN or Cellular. Current technology trends point toward a more seamlessly connected world, and for that to happen we must have cost-effective, low-power and highly connected dev... » read more

Experimental 36-core chip The more cores — or processing units — a computer chip has, the bigger the problem of communication between cores becomes. For years, Li-Shiuan Peh, the Singapore Research Professor of Electrical Engineering and Computer Science at MIT, has argued that the massively multicore chips of the future will need to resemble little Internets, where each core has an associ... » read more

Cheaper, lighter solar cells Think those flat, glassy solar panels on your neighbor’s roof are the best solar technology has to offer? Not so. Engineers in the University of Toronto’s Department of Electrical & Computer Engineering have designed and tested a new class of solar-sensitive nanoparticle that they say outperforms the current state of the art. Based on a new form of solid... » read more

Battery captures waste heat, converts it to electricity While vast amounts of excess heat are generated by industrial processes and by electric power plants, researchers around the world have spent decades looking for ways to harness some of this wasted energy, according to engineering researchers at Stanford and MIT. They pointed out that most of these efforts have focused on thermoelectric d... » read more

More electricity out of solar cells When sunlight shines on today’s solar cells, much of the incoming energy is given off as waste heat rather than electrical current but in a few materials, extra energy produces extra electrons. According to researchers at MIT, this behavior could significantly increase solar-cell efficiency. The team has identified the mechanism by which the phenomenon ... » read more

Nonlinear optical resonance The drive to develop ultrasmall and ultrafast electronic devices using a single atomic layer of semiconductors, such as transition metal dichalcogenides, has received a significant boost. Researchers with Berkeley Lab have recorded the first observations of a strong nonlinear optical resonance along the edges of a single layer of molybdenum disulfide. The existence ... » read more
