New findings could enhance stabilizing or destabilizing nanoparticles, depending on their uses University of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where stability is important, or to design them so they readily condense into thin films for such things as inks or...

Scientists: Coal Is Better, Cheaper For Making Graphene Quantum Dots
2013-12-06 16:55:31

Brett Smith for redOrbit.com – Your Universe Online A team of scientists from Rice University has found a way to use coal as a source of graphene quantum dots (GQD), tiny fluorescent particles that could be used in medical imaging and photovoltaic applications – according to a new report in Nature Communications. The use of coal to make GQDs would be much cheaper than conventional means, which are expensive and only produce small quantities. “We wanted to see what’s there in...

International Research Team Shows Distant Artificial Atoms Cooperate By Sharing Light
2013-11-14 15:52:07

University of Calgary Work is expected to have future applications in advanced quantum devices An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light. Quantum physicists have long discussed such an effect, but it has not been seen before in an experiment. The team included scientists from ETH Zürich (a leading university in Switzerland) who performed the experiment and theoretical...

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...

Physicists at the University of Basel have been successful in generating photons - the quantum particles of light – with only one color. This is useful for quantum information. The scientists have actively stabilized the wavelength of the photons emitted by a semiconductor thereby neutralizing the charge noise in the semiconductor. The results were developed in close collaboration with the Universities of Bochum, Paderborn and Lyon and have been published in the magazine Physical Review X....

Nanoparticles Mixed To Make Multifunctional Materials
2013-10-21 06:34:23

DOE/Brookhaven National Laboratory Standardized technique opens remarkable opportunities for 'mix and match' materials fabrication Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a general approach for combining different types of nanoparticles to produce large-scale composite materials. The technique, described in a paper published online by Nature Nanotechnology on October 20, 2013, opens many opportunities for mixing and matching particles...

Simulations help North and South Dakota researchers decide which technology would make a better solar collector, quantum dot or nanowire A trio of researchers at North Dakota State University, Fargo, and the University of South Dakota have turned to computer modeling to help decide which of two competing materials should get its day in the sun as the nanoscale energy-harvesting technology of future solar panels -- quantum dots or nanowires. Andrei Kryjevski and his colleagues, Dimitri...

Word of the Day
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
