Einzelne Photonen in einem Quantenpunkt erzeugen und seine Information zerstörungsfrei auslesen: Diese Technologie eröffnet neue Wege in der Quanteninformationsverarbeitung und -übertragung, die für künftige Computeranwendungen wegweisend sein können.
New work demonstrates that varistors and transistors are inherently coupled devices. These hybrid devices can simultaneously be used in the same electronic circuit as a varistor to protect the circuit elements against overshoot of prescribed voltage supply and as a transistor for signal amplification and electronic switch.
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought - and that the benefits of slow draining and charging may have been overestimated. The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.
In future, some diseases might be diagnosed earlier and treated more effectively. Researchers have developed an optical method that makes individual proteins, such as the proteins characteristic of some cancers, visible.
Researchers have developed a methodology for quantitatively describing the dynamic behaviors of complicated sugar chains in solution at atomic resolution by combining a sophisticated NMR spectroscopic approach with an ingenious molecular dynamics simulation technique.
Researchers have determined for the first time the mechanism by which nanometer-sized particles of palladium take up hydrogen. Because the properties of nanoparticles change greatly with their size, choosing the right types of nanoparticle allows you to fine-tune the properties of materials.
The EU project PIEZOVOLUME focused on speeding the production of piezoelectric film material. The research team worked to develop high-volume production tools and methods that are expected to help make the high-tech devices and systems of the future faster, lighter and more efficient.
An international collaboration of research teams has shown how an electron beam can move silicon atoms through the graphene lattice without causing damage. The research combines advanced electron microscopy with demanding computer simulations.
In the race to find more effective ways to treat cancer, Boise State University biophysicist Daniel Fologea is working outside the rules of general mathematics that say one plus one equals two. In his world, one plus one adds up to a whole lot more.
