New research reveals that pure gold nanoparticles found in everyday items such as personal care products, as well as drug delivery, MRI contrast agents and solar cells can inhibit adipose (fat) storage and lead to accelerated aging and wrinkling, slowed wound healing and the onset of diabetes.
In a scientific two-for-one deal, Cornell researchers have created compartment nanoparticles that may carry two or more different drugs to the same target. Meanwhile, the same technology gets applied to fuel cells, where catalysts may be formed into porous structures to expose more surface area.
Sales of chicken products in China plummeted recently during an outbreak of a deadly new strain of bird flu. From bird flu to mad cow disease, numerous food scares have made global headlines in recent years. A technique developed by University of Missouri Professor of Engineering Shubhra Gangopadhyay's group may make food contamination testing more rapid and accurate. The detection test also could accelerate warnings after bioterrorism attacks.
An advanced nanofocusing optic dubbed multilayer Laue lens is being developed by the optics fabrication group at Brookhaven National Laboratory's National Synchrotron Light Source II for nanoscale imaging.
An Indiana University School of Medicine breast cancer surgeon is pursuing research that will utilize glass, gold, nanotechnology and Greek mythology hoping to vanquish breast cancer that has metastasized to the brain.
The goal of INFINITEX (the Spanish acronym for Research into New Functions and Incorporated Intelligence in Textiles) project is to provide a boost to a national value chain for working with high added value functional and intelligent fabrics, as well as increasing their functions performances in terms of protection and comfort.
Researchers have created a simpler, greener bottom-up method that replaces some of the carbon atoms with boron and nitrogen. This enables them to 'grow' graphene-like honeycomb lattices, simply by exposing the compounds to light.
Like spreading a thin layer of butter on toast, Cornell scientists have helped develop a novel process of spreading extremely thin organic transistors, and used synchrotron X-rays to watch how the films crystallize.
Nanosilver in wastewater can cause severe environmental damage if it occurs as a metal. A study now shows that nanosilver is quickly transformed into less problematic substances on its way to the wastewater treatment plant.
A team of researchers from the NIST Center for Nanoscale Science and Technology, the University of Maryland, and Korea University (Seoul, Korea) has measured the nanoscale distribution of photoacid molecules in photoresists using a fluorescence technique originally developed to provide images of biological structures smaller than the wavelength of light.
Researchers from the National Institute of Standards and Technology (NIST) and Kansas State University have demonstrated a spray-on mixture of carbon nanotubes and ceramic that has unprecedented ability to resist damage while absorbing laser light.
Call it the ultimate nature documentary. Scientists at the University of Toronto have recorded atomic motions in real time, offering a glimpse into the very essence of chemistry and biology at the atomic level.
