It’s not X-ray vision, but you could call it infrared vision. A University at Buffalo-led research team has developed a technique for “seeing through” a stack of graphene sheets to identify and describe the electronic properties of each individual sheet — even when the sheets are covering each other up. The method involves shooting a beam of infrared light at the stack, and measuring how the light wave's direction of oscillation changes as it bounces off the layers within. To...

Funds enable further development of specialized lithium-ion anode materials, which can be used to create full-scale, high-capacity batteries. Lansing, Mich. (PRWEB) November 20, 2013 XG Sciences, Inc. (XGS) announced today it has been awarded $1 million in funding from the U.S. Department of Energy (DOE) for continued development of its XG SiG™ high-energy lithium-ion battery materials. These new anode materials have demonstrated energy storage capacity of up to four times that of...

A team of Clemson University physicists consisting of nanomaterial scientists Apparao Rao and Ramakrishna Podila and thermoelectricians Terry Tritt, Jian He and Pooja Puneet worked synergistically through the newly established Clemson Nanomaterials Center to develop a novel technique of tailoring thermoelectric properties of n-type bismuth telluride for high thermoelectric performance. Their findings were published in journal Scientific Reports. The current US energy economy and...

Engineers Create Smallest FM Radio Transmitter Using Graphene
2013-11-19 10:30:16

Ranjini Raghunath for redOrbit.com - Your Universe Online A team of engineers at Columbia University have created the smallest ever FM radio transmitter using a form of carbon known as graphene. The paper describing the device and its potential was published online on Nov. 17 in the journal Nature Nanotechnology. Like diamond or graphite, graphene is made up of carbon atoms that are laid out in hexagonal patterns in a layer a million times thinner than a sheet of paper. The team used...

Researchers Improve Nanopore-based Technology For Detecting DNA Molecules

Ecole Polytechnique Fédérale de Lausanne If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile. The latter resembles the model that EPFL researchers have used for creating a "DNA reader" that is able to detect the passage of individual DNA molecules through a tiny hole: a nanopore with integrated graphene transistor. The DNA molecules are diluted in a solution...

Researchers Grow Large Graphene Crystals That Have Exceptional Electrical Properties
2013-11-14 14:36:18

University of Texas at Austin When it comes to the growth of graphene — an ultrathin, ultrastrong, all-carbon material — it is survival of the fittest, according to researchers at The University of Texas at Austin. The team used surface oxygen to grow centimeter-size single graphene crystals on copper. The crystals were about 10,000 times as large as the largest crystals from only four years ago. Very large single crystals have exceptional electrical properties. "The game we play...

Researchers Develop Technique For Imaging Individual Carbon Nanotubes
2013-11-13 07:50:55

Lawrence Berkeley National Laboratory Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different “species,” each with its own structure and unique combination of electronic and optical properties. Characterizing the structure and properties of an individual carbon nanotube has involved a lot of guesswork – until now. Researchers with the U.S. Department of...
