Getting a charge out of water droplets

July 15, 2014 7:53 am | by David L. Chandler, MIT News Office | News | Comments

Last year, Massachusetts Institute of Technology researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices.

Nanoscale cooling element works in electrical insulators as well

July 8, 2014 8:45 am | News | Comments

An international research collaboration has designed a miniscule cooling element that uses spin waves to transport heat in electrical insulators. Although physicists have used spin for cooling purposes before, this is the first time that they have successfully done this in insulating materials. The cooling element could be used to dissipate heat in the increasingly smaller electrical components of computer chips.

An Android update, wearable gadgets, and so-called smart home devices are just some of the innovations Google is likely to show off at its two-day developer conference, which begins today in San Francisco. In recent years, the conference has focused on smartphones and tablets, but this year Google's Android operating system is expected to stretch into cars, homes, and smartwatches.

Metal particles in solids aren’t as fixed as they seem

June 25, 2014 8:04 am | by Nicole Casal Moore, Univ. of Michigan | News | Comments

In work that unmasks some of the magic behind memristors and "resistive random access memory," or RRAM, researchers have shown that the metal particles in memristors don't stay put as previously thought. The findings have broad implications for the semiconductor industry and beyond. They show, for the first time, exactly how some memristors remember.

Terahertz tech gets a major push

June 25, 2014 7:45 am | by Mike Williams, Rice Univ. | News | Comments

Rice Univ. scientists have received a grant to develop terahertz-based technology that could enable a dramatic advance in wireless communications and other disciplines. The $1 million grant by the W.M. Keck Foundation will let them tackle some of the knotty problems barring them from using the largely untapped terahertz region of the electromagnetic spectrum. Rice will supplement the grant with a $1.5 million commitment.

Wearable computing gloves can teach Braille

June 24, 2014 8:12 am | by Jason Maderer, Georgia Institute of Technology | News | Comments

Several years ago, Georgia Institute of Technology researchers created a technology-enhanced glove that can teach beginners how to play piano melodies in 45 min. Now they’ve advanced the same wearable computing technology to help people learn how to read and write Braille. The twist is that people wearing the glove don’t have to pay attention. They learn while doing something else.

Researchers unveil experimental 36-core chip

June 23, 2014 7:38 am | by Larry Hardesty, MIT News Office | News | Comments

The more cores a computer chip has, the bigger the problem of communication between cores becomes. For years, Li-Shiuan Peh, a professor of electrical engineering and computer science at Massachusetts Institute of Technology, has argued that the massively multicore chips of the future will need to resemble little Internets, where each core has an associated router, and data travels between cores in packets of fixed size.

Making smartphones smarter

June 19, 2014 10:29 am | by Lyndsay Meyer, The Optical Society | News | Comments

Your smartphone’s display glass could soon be more than just a pretty face, thanks to new technology developed by researchers from Corning Inc. The team has created the first laser-written light-guiding systems that are efficient enough to be developed for commercial use.

Energy-level alignment at metal/organic interfaces: Tying up the loose ends

June 19, 2014 8:33 am | News | Comments

Organic semiconductors have tremendous potential for complementing conventional, inorganic semiconductors, but energy losses or barriers at the connection interfaces have blocked development efforts. Physicists have now implemented a detailed electrostatic model which is capable of covering the full phenomenological range of interfacial energy-level alignment regimes within a single, consistent framework.

A new way to detect leaks in pipes

June 19, 2014 8:09 am | by David L. Chandler, MIT News Office | News | Comments

Explosions caused by leaking gas pipes have frequently made headlines in recent years. But while the problem of old and failing pipes has garnered much attention, methods for addressing such failing infrastructure have lagged far behind. Typically, leaks are found using aboveground acoustic sensors. But these systems are very slow, and can miss small leaks altogether. Now researchers have devised a robotic system that can detect leaks.
