Protecting Systems From Heat May Rely On Nano-Magnetic Fields
2013-11-21 08:30:42

April Flowers for redOrbit.com - Your Universe Online Generally, cooling systems rely on water pumped through pipes to remove unwanted heat. A research team from MIT and the University of Newcastle in Australia has discovered a method for enhancing heat transfer in such systems using magnetic fields. This new method could prevent hotspots that lead to system failures. The innovative new system, which relies on tiny particles of magnetite -- a form of iron oxide - could be applicable...

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...

BRUSSELS, November 18, 2013 /PRNewswire/ -- The "Ultrawire" project aims at producing a material that conducts electricity better than any known electrical conductor A consortium of 14 companies and universities has signed a EUR3.3 million funding contract through the European Commission's FP7 program. The project, termed "Ultrawire", aims to bring ultraconductive copper, a material that conducts electricity better than any known electrical...

Researchers Improve Nanopore-based Technology For Detecting DNA Molecules
2013-11-18 08:34:01

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...

New Hologram Technology Created Using Tiny Nanoantennas
2013-11-15 10:27:00

Purdue University Researchers have created tiny holograms using a "metasurface" capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing. The metasurface, thousands of V-shaped nanoantennas formed into an ultrathin gold foil, could make possible "planar photonics" devices and optical switches small enough to be integrated into computer chips for information processing, sensing and...

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...

In-demand research report “Market Opportunities for Quantum Dots in Lighting and Displays” elaborated by NanoMarkets has been recently published by Market Publishers Ltd. London, UK (PRWEB) November 13, 2013 Quantum dots are semiconductor nanoparticles, with dimensions typically ranging from 2 to 10 nm. Their diminutiveness makes them highly flexible and versatile and therefore suitable for a lot of applications. Currently, the healthcare sector is the largest application for QD-based...

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...
