When I thought I saw all in the field of cleaning, I found out that a team of German scientists at FAU – Friedrich-Alexander University from Nürnberg, Germany have completed a new method for mechanical cleaning of surfaces at nanoscale. Their technique removes even the tiniest contaminants down to the atomic scale, performing a cleaning […]

Thanks to a little serendipity, researchers at Rice University have created a tiny coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable, which is described this week in Nature Communications, was produced with techniques pioneered in the nascent graphene research field […]

A group of young research students at School of Engineering from Standford has developed an ultrafast nanoscale light-emitting diode (LED) that is able to transmit data with 10 billion bits per second, a very, very rapid rate and with lower power consumption. This is a major step forward in providing a practical ultrafast and low-power […]

Self-cooling effect in graphene at nanoscale

Gabriel — Mon, 04 Apr 2011 18:58:43 +0000

With the first observation of thermoelectric effects at graphene contacts, University of Illinois researchers found that graphene transistors have a nanoscale cooling effect that reduces their temperature. The speed and size of computer chips are limited by how much heat they dissipate. All electronics dissipate heat as a result of the electrons in the current […]

First practical nanogenerator could replace conventional batteries

Gabriel — Thu, 31 Mar 2011 20:11:59 +0000

After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements — a finger pinch now en route to a pulse beat in the future — to generate electricity. Speaking at the 241st National Meeting & Exposition of the American Chemical Society, […]

Converting Heat Waste to Electricity Closer To Reality

Gabriel — Tue, 18 Jan 2011 20:39:55 +0000

Researchers at Northwestern University have placed nanocrystals of rock salt into lead telluride, creating a material that can harness electricity from heat-generating items such as vehicle exhaust systems, industrial processes and equipment and sun light more efficiently than scientists have seen in the past. The material exhibits a high thermoelectric figure of merit that is […]

How to convert waste heat to electricity at the nanoscale

Gabriel — Sat, 18 Dec 2010 20:37:11 +0000

Scientists have discovered that a class of materials known to convert heat to electricity and vice versa behaves quite unexpectedly at the nanoscale in response to changes in temperature. The discovery — described in the December 17, 2010, issue of Science — is a new “opposite-direction” phase transition that helps explain the strong thermoelectric response […]
