What appear under an atomic force microscope to be tiny rings with little bits missing are actually nanoscopic rings made of double-stranded DNA with a little gap in the form of a short single-stranded fragment. This gap is a place to attach other molecules that have the potential to transform the rings into versatile nanocomposites for various applications.
Microscopic fissures in a tiny crystal open and close—on command. Researchers successfully used ultrafast electron microscopy to observe nanoscopic structures at their 'exercises', as they report in the journal Angewandte Chemie. Such switchable nanochannels could be useful for future nanoelectronics and nanoscopic 'machines'.
Not only is our body made of individual organs, our cells themselves are made of tiny organelles, a variety of separate compartments that fulfill different tasks. Such functional, nanostructured systems would also be useful for technical applications, such as biosensors, self-repairing materials, optoelectronic components, or nanocapsules. However, it has not been possible to recreate structures with sufficient complexity in the lab. Researchers in the Netherlands are now pursuing a new angle.
Qatar Foundation will organize an international symposium on applied nanomedicine in an effort to acquaint the local community with the utility of this futuristic medical science from March 9 to 10 at the Doha Sheraton Hotel.
Nanotechnology is everywhere today in consumer products, emerging medicines and scientific research. Which advances will change our lives the most? What role will regulation play as the field develops? And how can journalists best convey both the promise and potential risks of this emerging technology?
The University of Utah today announced a $1.25 million pledge from the Micron Technology Foundation to support the development of a nanofabrication teaching and research laboratory as a core facility in the new Utah Science, Technology and Research (USTAR) building now under development on the university’s campus.
The first patent awarded to Southeastern Louisiana University through one of its faculty has the potential to identify weaknesses in structures ranging from massive bridge construction to the tiniest elements of nanotechnology no larger than a speck of dust on a pinhead.
The Pentagon on Monday released its latest analysis of China's military development and strategy and says that the country spent as much as $139 billion, more than three times its announced defense budget, modernizing its military forces last year and that China has gone from virtually no research or funding in nanotechnologies and processes five years ago, to being a close second to the United States in total government investment.
Two research teams led by Dr. Michael Verkhovsky and Prof. Marten Wikstrom of the Institute of Biotechnology of the University of Helsinki have for the first time succeeded in monitoring electron transfer by Complex I in real time. In the future, this work might, for example, have medical relevance, because most of the maternally inherited so-called mitochondrial diseases are caused by dysfunction of Complex I.
Ian Appelbaum, assistant professor of electrical and computer engineering at the University of Delaware, has received the prestigious Faculty Early Career Development Award from the National Science Foundation for his pioneering research in the exciting next evolution of electronics known as spintronics.
Researchers at the University of Pennsylvania have found that, while metals tend to be stronger at nanoscale volumes, their strengths saturate at around 10-50 nanometers diameter, at which point they also become more sensitive to temperature and strain rate.
Governor Eliot Spitzer today announced the selection of the Rochester Institute of Technology as the host of the Pollution Prevention Institute, a cutting-edge research and development center to design and test 'green' manufacturing methods and provide technical support to businesses for pollution reduction measures that will help make them more competitive.
