Exploiting Flaws In Diamond Fragments Paves Way For Nanoscale MRI
2013-11-25 08:02:31

University of Cambridge By exploiting flaws in miniscule diamond fragments, researchers say they have achieved enough coherence of the magnetic moment inherent in these defects to harness their potential for precise quantum sensors in a material that is 'biocompatible'. Nanoscopic thermal and magnetic field detectors - which can be inserted into living cells - could enhance our understanding of everything from chemical reactions within single cells to signalling in neural networks and...

Study Shows Another Feature That Affects Electron Transport In Graphene
2013-11-21 16:27:26

University of Wisconsin - Milwaukee For all the promise of graphene as a material for next-generation electronics and quantum computing, scientists still don't know enough about this high-performance conductor to effectively control an electric current. Graphene, a one-atom-thick layer of carbon, conducts electricity so efficiently that the electrons are difficult to control. And control will be necessary before this wonder material can be used to make nanoscale transistors or other...

2-D Tin Could Be The Next Super Material

SLAC National Accelerator Laboratory Theorists Predict New Single-Layer Material Could Go Beyond Graphene, Conducting Electricity with 100 Percent Efficiency at Room Temperature A single layer of tin atoms could be the world’s first material to conduct electricity with 100 percent efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory...

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...

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...

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...


Word of the Day
sough
  • A murmuring sound; a rushing or whistling sound, like that of the wind; a deep sigh.
  • A gentle breeze; a waft; a breath.
  • Any rumor that engages general attention.
  • A cant or whining mode of speaking, especially in preaching or praying; the chant or recitative characteristic of the old Presbyterians in Scotland.
  • To make a rushing, whistling, or sighing sound; emit a hollow murmur; murmur or sigh like the wind.
  • To breathe in or as in sleep.
  • To utter in a whining or monotonous tone.
According to the OED, from the 16th century, this word is 'almost exclusively Scots and northern dialect until adopted in general literary use in the 19th.'
