Using a mechanical grinding technique that allowed them to control the structure of a metal's surface on the nanoscale, Ke Lu and colleagues from the Chinese Academy of Science's Institute for Metal Research in Shenyang have overcome the frustrating tradeoff between strength and brittleness to produce a protective copper surface that is both strong and ductile.
Stanford researchers have developed an improved imaging method using fluorescent carbon nanotubes that allows them to see centimeters deep into a mouse with far more clarity than conventional dyes provide. For a creature the size of a mouse, a few centimeters makes a great difference.
The National Physical Laboratory (NPL) in the UK is developing three optical techniques that use light scattering to make these measurements in solid polymers: frequency-domain optical coherence tomography (FD-OCT), Fraunhofer wavefront correlation (FWC) and oscillatory photon correlation spectroscopy (Os-PCS).
At the forefront of nanotechnology, researchers design miniature machines to do big jobs, from treating diseases to harnessing sunlight for energy. But as they push the limits of this technology, devices are becoming so small and sensitive that the behavior of individual atoms starts to get in the way. Now Caltech researchers have, for the first time, measured and characterized these atomic fluctuations - which cause statistical noise - in a nanoscale device.
Nanotechnology is opening up new markets and offering novel solutions to numerous challenges in a very varied range of areas. This was the tenor of the 1st Swiss NanoConvention which took place on May 18 and 19 in Baden.
A general rule in data processing is that disturbances cause the distortion or deletion of information during data storage or transfer. Methods for conventional computers were developed that automatically identify and correct errors: Data are processed several times and if errors occur, the most likely correct option is chosen. As quantum systems are even more sensitive to environmental disturbances than classical systems, a quantum computer requires a highly efficient algorithm for error correction.
Medicine and technology are converging in patient care at a faster pace than most people realize. Space age advancements from point-of-care health technologies like telemedicine to medical robots performing surgery are fast becoming commonplace in many hospitals. What's next?
A newly released OECD document provides a snapshot of information on current/planned activities related to the safety of manufactured nanomaterials in OECD member countries and other delegations that attended the 8th meeting of OECD's Working Party on Manufactured Nanomaterials (Paris France, 16-18 March 2011).
Vanderbilt University engineers have created a "spongy" silicon biosensor that shows promise not only for medical diagnostics, but also for the detection of dangerous toxins and other tiny molecules in the environment. This innovation was originally designed to detect the presence of particular DNA sequences, which can be extremely helpful in identifying whether or not a person is predisposed to heart disease or certain kinds of cancer.
