When semiconductor nanorods are exposed to light, they blink in a seemingly random pattern. By clustering nanorods together, physicists at the University of Pennsylvania have shown that their combined "on" time is increased dramatically providing new insight into this mysterious blinking behavior. The research was conducted by associate professor Marija Drndic's group, including graduate student Siying Wang and postdoctorial fellows Claudia Querner and Tali Dadosh, all of the Department of...

(Ivanhoe Newswire)-- New medical technology is showing that Cornell dots may be a potential cancer diagnostic tool. The U.S Food and Drug Administration (FDA) has recently approved the first clinical trial in humans using Cornell Dots- brightly glowing nanoparticles that can light up cancer cells in PET-optical imaging. Cornell Dots are silica spheres less than eight nanometers in diameter that enclose several dye molecules. To make the dots stick to tumor cells, organic molecules that bind...

A new generation of high speed, silicon-based information technology has been brought a step closer by researchers in the Department of Electronic and Electrical Engineering at UCL and the London Centre for Nanotechnology. The team's research, published in next week's Nature Photonics journal, provides the first demonstration of an electrically driven, quantum dot laser grown directly on a silicon substrate (Si) with a wavelength (1300-nm) suitable for use in telecommunications. Silicon is...

Researchers at the Hebrew University of Jerusalem have achieved a breakthrough in the field of nanoscience by successfully altering nanocrystal properties with impurity atoms -- a process called doping "“ thereby opening the way for the manufacture of improved semiconductor nanocrystals. Semiconductor nanocrystals consist of tens to thousands of atoms and are 10,000 times smaller than the width of a human hair. These tiny particles have uses in a host of fields, such as solid-state...

A team of physicists in the United Kingdom has taken a giant step toward realizing efficient single-photon sources, which are expected to enable much-coveted completely secure optical communications, also known as "quantum cryptography." The team presents its findings in Applied Physics Letters, a journal published by the American Institute of Physics. Fluorescent "defect centers" in diamond act like atomic-scale light sources and are trapped in a transparent material that's large enough to...


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.
