Electrical engineers at The University of Texas at Arlington and at the University of Wisconsin-Madison have devised a new laser for on-chip optical connections that could give computers a huge boost in speed and energy efficiency.
Researchers from the FOM Foundation and Eindhoven University of Technology have successfully made a 'magnetic domain-wall ratchet' memory, a computer memory that is built up from moving bits of magnetised areas. This memory potentially offers many advantages compared to standard hard disks, such as a higher speed, lower electricity consumption and much longer life.
Sixteen students from ten different countries are currently taking part in the 'Nano Summer Program' organized by the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen. Over the course of the seven-week program, these students will expand their knowledge of all things 'nano' and have an opportunity to network with leading experts in the field.
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.
