Researchers at North Carolina State University have developed a cheap and easy method for assembling nanowires, controlling their alignment and density. The researchers hope the findings will foster additional research into a range of device applications using nanowires, from nanoelectronics to nanosensors, especially on unconventional substrates such as rubber, plastic and paper. "Alignment is a critical first step for developing devices that use nanowires," says Dr. Yong Zhu, an assistant...

Bochum physicists are constructing 0-dimensional systems Through his participation, the research team from Bochum, Duisburg-Essen, and Hamburg now has succeeded in an energy-state occupancy readout of those artificial atoms "“ using common interfaces to classic computers. This is a big step towards the application of such systems. They report about their findings in Nature Communications. One million instead of individual atoms In principle, the spin of electrons in individual atoms can...

Pure organic compounds that glow in jewel tones could potentially lead to cheaper, more efficient and flexible display screens, among other applications. University of Michigan researcher Jinsang Kim and his colleagues have developed a new class of material that shines with phosphorescence---a property that has previously been seen only in non-organic compounds or organometallics. Kim and his colleagues made metal-free organic crystals that are white in visible light and radiate blue, green,...

The work could lead to improved methodologies for creating materials by design Scientists have given us a plethora of new materials "“ all created by combining individual elements under varying temperatures and other conditions. But to tweak an intermetallic compound even more, in order to give it the attributes you desire, you have to go deeper and re-arrange individual atoms. It's a process similar to what bioengineers employ when they add and delete genes to create synthetic...

Sophisticated tools allow scientists to subject the basic elements of matter to conditions drastic enough to modify their behavior. By doing this, they can expand our understanding of matter. A research team including three Carnegie scientists was able to demonstrate surprising properties of the element lithium under intense pressure and low temperatures. Their results were published Jan. 9 on the Nature Physics website. Lithium is the first metal in the periodic table and is the least dense...

First model of rapid phase change in storage material Although the storage of films and music on a DVD is part of our digital world, the physical basis of the storage mechanism is not understood in detail. In the current issue of the leading journal Nature Materials, researchers from Jlich, Finland, and Japan provide insight into the read and write processes in a DVD. This knowledge should enable improved storage materials to be developed. (DOI: 10.1038/NMAT2931) Information is stored in a...

NEW YORK, Dec. 8, 2010 /PRNewswire/ -- Dr. Richard Gross, professor of chemical and biological science at Polytechnic Institute of New York University (NYU-Poly), has developed a method for producing a strong, highly ductile bioplastic using yeast and one of nature's simplest building blocks: fatty acids of plant oils. The findings were published in the Journal of the American Chemical Society. (Logo: http://photos.prnewswire.com/prnh/20091027/NY99197LOGO ) Like all plastics, the new...

Glass is something we all know about. It's what we sip our drinks from, what we look out of to see what the weather is like before going outside and it is the backbone to our high speed communications infrastructure (optical fibers). But what most people don't know is that "glass transitions," where changes in structure of a substance accompanying temperature change get "frozen in," can show up during cooling of most any material, liquids through metals. This produces "glassy states," of that...

Materials scientists from Case Western Reserve University and the Institute of Solid State Research in Jlich, Germany have produced particularly clear changes in the atomic structure of sapphire following deformation at high temperatures. Peering through an electron microscope down to a level where a human hair would seem as wide as a washer and dryer set, they were able to quantify deviations from the regular columns of aluminum and oxygen atoms - the stuff of perfect sapphire crystals. The...


Word of the Day
cock-a-hoop
  • 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.'
