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.
Ulsan National Institute of Science and Technology (UNIST) announced a method for the mass production of boron/nitrogen co-doped graphene nanoplatelets, which led to the fabrication of a graphene-based field -effect transistor (FET) with semiconducting nature. This opens up opportunities for practical use in electronic devices.
In the quest to shrink motors so they can maneuver in tiny spaces like inside and between human cells, scientists have taken inspiration from millions of years of plant evolution and incorporated, for the first time, corkscrew structures from plants into a new kind of helical 'microswimmer'.
The world's largest scientific centers are losing some of their prominence due to geographical decentralization at the global scale, according to a team of researchers who conducted a systematic statistical analysis of millions of articles and papers published in thousands of scientific reviews between 1987 and 2007.
The new Australian Research Council (ARC) Center of Excellence for Nanoscale BioPhotonics will cross the boundaries of biology, lasers and nanoscience, using light-based sensors to probe molecular processes within living systems.
