The amount of damage that radiation causes in electronic materials may be at least ten times greater than previously thought. That is the surprising result of a new characterization method that uses a combination of lasers and acoustic waves to provide scientists with a capability tantamount to X-ray vision: It allows them to peer through solid materials to pinpoint the size and location of detects buried deep inside with unprecedented precision.
A University of Nebraska Medical Center research team's progress toward developing weekly or twice-monthly injectable antiretroviral therapy (ART) nanomedicines for patients with human immunodeficiency virus (HIV) infection.
UCLA researchers have developed a new transparent solar cell that is an advance toward giving windows in homes and other buildings the ability to generate electricity while still allowing people to see outside.
A new concept of electrode fabrication based on sealing nanoparticles between layers of pure carbon nanotubes was developed. When this novel electrode was used as a cathode, the inherent iron vacancies allowed for significantly increased performance in a lithium-ion battery.
Researchers are designing, by means of laser application, nanostructured reliefs on surfaces so that they acquire antibacterial properties and are more resistant to the formation of bacterial biofilms.
Researchers have made a significant step in utilizing the electrons' spin for transistor action. If spin-based electronics prevails the new switching concept might turn out to be useful as it allows for switching the spin-polarization of an electric current on and off, tuning it continuously or reading it off electrically by simple resistance measurements.
A new experiment conducted at the Joint Quantum Institute examines the relationship between quantum coherence, an important aspect of certain materials kept at low temperature, and the imperfections in those materials. These findings should be useful in forging a better understanding of disorder, and in turn in developing better quantum-based devices, such as superconducting magnets.
Im Forschungsprojekt 'nanoEES3D' werden Forsche ganz genau betrachten, wie sie das Zusammenspiel von Oberflächenstruktur und Poren von Hochleistungskohlenstoffen für den schnellen Transport von Ionen verbessern können.
Researcher from the University of West Florida has designed an ultracapacitor that maintains a near steady voltage. The novel constant-voltage desig may one day help ultracapacitors find new uses in low-voltage electric vehicle circuits and handheld electronics.
KU Leuven researcher Ventsislav Valev and an international team of colleagues have developed a new method for manipulating light at the nanoscale in order to optically detect single molecules. By shining circularly polarised light on a gold, square-ring shaped nanostructure, the researchers were able to 'activate' the entire surface of the nanostructure, thereby significantly increasing the opportunity for interaction with molecules.
