High technology is now at our fingertips – literally. A new type of disposable glove emits chlorine dioxide when exposed to light or moisture, killing potentially harmful microbes and making it ideal for use among health care and food workers, according to a study in the March 15 issue of Clinical Infectious Diseases, now available online.
The vinyl or polyethylene gloves contain microspheres that release chlorine dioxide, a water-soluble gas used to disinfect drinking water and processed f
A team of American and British scientists has demonstrated an artificially made material that can provide a magnetic response to Terahertz frequency radiation, bringing the realisation and development of novel ‘T-ray’ devices a step closer.
The advance, reported in the journal Science (5 March), suggests many applications in biological and security imaging, biomolecular fingerprinting, remote sensing and guidance in zero visibility weather conditions, say the authors.
Researchers at the University of Pennsylvania have devised a new method for aligning isolated single wall carbon nanotubes and, in the process, have created a new kind of material with liquid crystal-like properties, which they call nematic nanotube gels. The gels could potentially serve as sensors in complex fluids, where changes in local chemical environment, such as acidity or solvent quality, can lead to visible changes in the gel shape. The researchers describe their findings in the current i
High-quality nanopowders made of refractory ceramics are a rare and very expensive material. All known methods of their manufacturing face the same problems – scanty quantities, extensive variety of particle sizes and expensive production. Researchers from the town of Tomsk have invented and manufactured a device to produce a choice selection of particles – all particles are equal to the required size and inexpensive. The project has been funded by two foundations – the Russian Foundation for Basic R
For nanoelectronics, biotechnology
An article to be published in the February 27 issue of the journal Science introduces “nanorings” as the newest member of a growing family of nanometer-scale structures based on single crystals of zinc oxide, a semiconducting and piezoelectric material that has important technological applications.
The rings, complete circles formed by a spontaneous self-coiling process, could serve as nanometer-scale sensors, resonators and transducers – a
“Nature was nano before nano was cool,” stated Henry Fountain in a recent New York Times article on the proliferation of nanotechnology research projects. No one is more aware of this fact of nature than Dan Morse of the University of California, Santa Barbara. His research groups have been studying the ways that nature builds ocean organisms at the nanoscale for over ten years.
For example, they have studied the abalone shell for its high-performance, super-resistant, composite mineral str
