Physiker der Universität Leipzig haben gemeinsam mit Wissenschaftlern aus Göttingen eine Laserapparatur zur Erzeugung extrem kurzwelliger UV-Strahlung an Nanostrukturen im Labor entwickelt und damit einen wichtigen Schritt zur Erforschung extrem schneller oder sehr kleiner Objekte getan.
Using swarms of untethered grippers, each as small as a speck of dust, engineers and physicians have devised a new way to perform biopsies that could provide a more effective way to access narrow conduits in the body as well as find early signs of cancer or other diseases.
Researchers from North Carolina State University have solved a long-standing materials science problem, making it possible to create new semiconductor devices using zinc oxide -- including efficient ultraviolet lasers and LED devices for use in sensors and drinking water treatment, as well as new ferromagnetic devices.
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have taken an important step toward harnessing that heat and converting it for practical use. The advance could lead to more energy-efficient appliances and information processing devices.
An international team of scientists has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level.
Each year, twice as many people die in Europe from hospital acquired infections than from road accidents. These infectious diseases have developed antibiotic resistance and spread despite the best efforts of staff, mainly through textiles like bed linen. But the technology developed by a European research project helps fight back against the so-called superbugs, by using a revolutionary nanotechnology to treat bed linen and other textiles.
Pioneering biophotonics technology developed at Northwestern University is the first screening method to detect the early presence of ovarian cancer in humans by examining cells easily brushed from the neighboring cervix or uterus, not the ovaries themselves.
The latest advances in microtechnologies for smart sensors, energy harvesting, smart power, reconfigurable multimedia, wireless communication, and biomedical applications will be presented next month in Grenoble at SPIE Microtechnologies. The event attracts researchers and developers for an interdisciplinary exchange of technology advances and discussion of future applications.
A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize specific kinds of polarized light and accordingly send the signal in one direction or another.
