|FEATURED INSTITUTION: Brookhaven Lab Tests Hybrid Nanoparticles for Energy Sources|
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory Center for Functional Nanomaterials have assembled nanoscale pairings of quantum dots and fullerenes that show promise as miniaturized power sources. The nanoscale systems can convert light to electricity in a controlled way.
The team from Brookhaven’s Center for Functional Nanomaterials (CFN) developed a precision fabrication method which allows them to carefully control particle size and inter-particle distance. This added control, in turn, lets researchers work with light-induced electron transfer at the molecular level -- even between individual quantum dots and fullerenes.

|FDA Approves Cornell Dots for Human Trials |
The FDA (U.S. Food and Drug Administration) has approved the first clinical trial in humans of Cornell dots, brightly glowing nanoparticles that can light up cancer cells in PET-optical imaging. The technology aims to safely show surgeons extent of tumors in human organs. FDA’s decision arises from collaborative work between Memorial Sloan-Kettering Cancer Center (MSKCC), Cornell University, and Hybrid Silica Technologies, a Cornell business start-up.
|U.S., Chinese Nanoscientists Team Up on Novel Rechargeable Batteries |
U.S. and Chinese researchers have developed a novel method designed to improve the electrical capacity and recharge lifetime of sodium ion rechargeable batteries. The work could be a cost-effective way to connect solar and wind energy sources to the electrical grid, the team said.
The work was reported by scientists from the U.S. Department of Energy's Pacific Northwest National Laboratory and visiting Chinese researchers from Wuhan University in Wuhan.
|FEATURED RESEARCHER: Sandu Popescu Receives Bell Prize for Quantum Mechanics|
Noted quantum physicist Sandu Popescu has been named the recipient of the prestigious John Stewart Bell Prize from University of Toronto for outstanding contributions to quantum mechanics. The award recognizes work related to foundations and application of principles across information theory, computation, cryptography and control. Prof. Popescu is based at the UK’s University of Bristol.
|Ohio Researchers Advance Toward Hybrid Spintronic Computer Chips|
A team at Ohio State University has created the first electronic circuit to merge inorganic semiconductors with organic "spintronics" -- devices that utilize the spin of electrons to read, write and manipulate data.
|Graphene May Get On-Off Switch Thanks for Lasers|
International researchers have proposed a way to turn graphene into a semiconductor, enabling it to control the flow of electrons with a laser "on-off switch.” Illuminating graphene with a mid-infrared laser could be a key to switch off conduction, thereby improving the possibilities for novel optoelectronic devices, according to the team.
|Nano Devices with Bluetooth? |
Scientists report they have developed a self-powered nano-device that can transmit data wirelessly over long distances. The device consists of a nanogenerator that produces electricity from mechanical vibration/triggering, a capacitor, sensor and a radio transmitter similar to those in Bluetooth mobile phone headsets. The nanodevice sent wireless signals detectable at 30 feet by commercial radios.
