Scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first time, the imaging of nanoscale processes, such as the engulfment of nanoparticles into cells.
The energy sector is currently facing important technological challenges, not only to incorporate renewable energies but also to modify and make the entire energy production and distribution system more efficient. Nanotechnology developments offer unique solutions which are applicable to the generation, distribution, transportation and storage of energy and the numerous technological developments in this field are numerous.
Researchers have been able to improve the efficiency of solar cells by coating the cell surface with extremely small nanoscale structures. The new technology has been shown to nearly eliminate the reflection losses of solar radiation.
Researchers at Tyndall National Institute at UCC in Cork, Ireland are leading an international project in advanced nanoelectronics which is aimed at maintaining Europe's position as a world leader in innovative automotive power electronic systems for both conventional and electric cars.
Changes in the bases that make up DNA act as markers, telling a cell which genes it should read and which it shouldn't. A British team has now introduced a new method that makes it possible to enrich the rare gene segments that contain the modified base hydroxymethylcytosine and to identify individual hydroxymethylcytosine molecules in DNA.
University of Nebraska-Lincoln materials engineers have developed a structural nanofiber that is both strong and tough, a discovery that could transform everything from airplanes and bridges to body armor and bicycles.
Researchers at Northeastern University in Boston have developed a gene therapy approach that may one day stop Parkinson's disease (PD) in it tracks, preventing disease progression and reversing its symptoms. The novelty of the approach lies in the nasal route of administration and nanoparticles containing a gene capable of rescuing dying neurons in the brain.
A successful project to educate school pupils across Bristol and South Gloucestershire about nanotechnology has climaxed in a debate about whether the manipulation of very small particles could be the answer to the world's energy problems.
Already renowned for its beneficial effects on human health, green tea could have a new role - along with other natural plant-based substances - in a healthier, more sustainable production of the most widely used family of nanoparticles, scientists say.
