Researchers in the United States and Austria report an advance toward the next generation of plastic solar cells, which are widely heralded as a low cost, environmentally-friendly alternative to inorganic solar cells for meeting rising energy demands.
In yet another twist on the strangeness of the nanoworld, researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park have discovered that materials such as silica that are quite brittle in bulk form behave as ductile as gold at the nanoscale. Their results may affect the design of future nanomachines.
Bottom-up manufacturing may hold the key to production of tiny medical devices capable of testing for multiple molecules like viruses or cancer markers, according to an interdisciplinary team of Penn State researchers.
'Tehran is ready to make available to Jakarta its achievements and its valuable experience in a variety of fields, including in nuclear engineering, nanotechnology and economics,' Mahmoud Ahmadinejad said at a joint news conference with Indonesian President Susilo Bambang Yudhoyono, who is on a two-day official visit to Tehran.
IMEC reports a variability-aware modeling (VAM) flow that analyzes process variability of sub-45nm technologies which enables designers to optimize their system design for timing, energy and yield versus expected application load.
MEDi 2008, the most comprehensive medical device conference and exhibition, will be held at the new Connecticut Convention Center in Hartford, Tuesday and Wednesday, September 9-10. MEDi 2008 will showcase the latest developments in nanomedicine, drug delivery vehicles, drug/device combination products, robotic surgery, orthopedic implants and prosthetic devices, artificial organs and eHealth, while also providing conferences addressing important issues and business challenges related to the manufacture and commercialization of these devices.
Food, packaging and agricultural products containing manufactured nanomaterials pose a toxic health risk and should be suspended from sale until new safety testing, laws and appropriate labelling are created, a new report says.
Filling the major gaps that exist in the understanding of the health, safety, environmental and societal impacts of nanotechnology is critically important to its long term success, a researcher said yesterday. Lori Sheremeta, research officer at the Canadian Institute for Nanotechnology, was making a presentation on ?Nanotechnology Stewardship? on the concluding day of the first international symposium on applied nanomedicine, hosted by Qatar Foundation.
A researcher at the National University at San Diego has taken a mathematical approach to a biological problem - how to design a portable DNA detector. He describes a mathematical simulation to show how a new type of nanoscale transistor might be coupled to a DNA sensor system to produce a characteristic signal for specific DNA fragments in a sample.
