BRIDGEWATER, N.J., March 1, 2011 /PRNewswire/ -- Hamamatsu Photonics has introduced the new Quantaurus series of compact instruments for measuring the properties of photoluminescent materials. The new Quantaurus-Tau measures fluorescence lifetimes as short as 100 picoseconds, while the Quantaurus-QY measures quantum yields faster and more easily than the traditional relative measurement method. The combination of these two instruments enables a comprehensive characterization of...

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...

Like snowflakes or fingerprints, no two quantum dots are identical. But a new etching method for shaping and positioning these semiconductor nanocrystals might change that. What's more, tests at the National Institute of Standards and Technology (NIST) confirm that etched quantum dots emit single particles of light (photons), boosting prospects for powering new types of devices for quantum communications. The conventional way to build quantum dots"”at NIST and elsewhere"”is to...

The sun provides more than enough energy for all our needs, if only we could harness it cheaply and efficiently. Solar energy could provide a clean alternative to fossil fuels, but the high cost of solar cells has been a major barrier to their widespread use. Stanford researchers have found that adding a single layer of organic molecules to a solar cell can increase its efficiency three-fold and could lead to cheaper, more efficient solar panels. Their results were published online in ACS...

An interdisciplinary team of researchers at UC Santa Barbara has produced a groundbreaking study of how nanoparticles are able to biomagnify in a simple microbial food chain. "This was a simple scientific curiosity," said Patricia Holden, professor in UCSB's Bren School of Environmental Science & Management and the corresponding author of the study, published in an early online edition of the journal Nature Nanotechnology. "But it is also of great importance to this new field of looking...

Newly fabricated devices are a step toward quantum computing Moving a step closer toward quantum computing, a research team in the Netherlands recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere 7,000 cubic nanometers. The device is described in the American Institute of Physics' journal Applied Physics Letters. Photodetectors based on single quantum dots are expected to find uses in optoelectrical...

One of the holy grails of nanotechnology in medicine is to control individual structures and processes inside a cell. Nanoparticles are well suited for this purpose because of their small size; they can also be engineered for specific intracellular tasks. When nanoparticles are excited by radio-frequency (RF) electromagnetic fields, interesting effects may occur. For example, the cell nucleus could get damaged inducing cell death; DNA might melt; or protein aggregates might get dispersed....


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
