Researchers have demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length within 60 milliseconds - faster than the blink of an eye.
Researchers have developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology.
NIOSH has released a document titled, Current Strategies for Engineering Controls in Nanomaterial Production and Downstream Handling Processes, which provides information on how to control exposures for many of the most common processes seen in facilities that use or produce nanomaterials or nano-enabled products.
Using nanofabricated waveguides in a silicon-based platform, researchers have developed a frequency conversion interface between the optical transition wavelengths in quantum dots and in naturally occurring atoms and the telecommunications wavelength band.
A single layer takes on the job of what used to be two layers, doing away with the wet chemical process. Despite a much simplified production method, efficiencies of greater than 18 percent are well within reach.
In a survey of nano-scientists and engineers, nano-environmental health and safety scientists, and regulators, researchers at the UCSB Center for Nanotechnology in Society and at the University of British Columbia found that those who perceive the risks posed by nanotechnology as 'novel' are more likely to believe that regulators are unprepared.
The introduction of new technologies such as information technology, space technologies, nanotechnology and robotic technologies into our civil life, and into warfare, is expected to influence the application and interpretation of the existing rules of the law of armed conflict.
A new research review provides one of the most comprehensive assessments to date of research on nanotechnology-based approaches to treating cancer and offers insight into how researchers can best position nanomedicine-based cancer treatments for FDA approval.
After successfully text messaging 'O Canada' using evaporated vodka, two York University researchers and their UK-based counterpart say their simple system can be used where conventional wireless technology fails.
