Researchers have engineered a nanowire system that could pave the way for this ability, combining two light waves to produce a third with a different frequency and using an optical cavity to amplify the intensity of the output to a usable level.
Researchers visualized the electronic interactions of magnetic impurities in metals. In doing so, they discovered that the electron patterns which arise around magnetic foreign atoms as a result of the Kondo effect interact over greater distances than previously thought. The insights from the examination of a simple model system could be beneficial in understanding materials with complex electronic structures. (in German)
The National Physical Laboratory (NPL) and The University of Manchester have signed a memorandum of understanding to help move the potential benefits of graphene closer to practical use, by accelerating the commercialisation of the remarkable 2D material.
An optical oscilloscope with 20 times the resolution of conventional electronics has been developed by the ARC Centre for ultrahigh bandwidth devices for optical systems (CUDOS) at the University of Sydney and the Australian National University.
University of Arkansas for Medical Sciences researcher Vladimir Zharov recently was awarded a $1.5 million R01 grant by the National Institutes of Health to investigate his diagnostic concept - 'in vivo reading written in blood' - with new stimuli-responsive nanoparticles circulating in blood.
A research team in Japan has shown that a molecular electronic switch with multi-conductance states (for example, high, medium and low states) is possible using a single quarter thiophene-based junction. In this new switch, the switching behavior is triggered by external mechanical force.
Researchers have shown that small size pure graphene nanosheets may work as an effective catalyst for breaking oxygen molecules - a reaction, which is of importance in the operation of fuel cells and air batteries, both of which have the potential to power electronic devices, vehicles, aircrafts and equipment.
Fraunhofer FEP presents latest approaches to fabricate OLED devices for lab-on-a-chip-applications using either near UV electroluminescence or optically modulated green light to stimulate fluorescent dye markers.
Applying a thin film of metallic oxide significantly boosts the performance of solar panel cells. Researchers have developed a new class of materials comprising elements such as bismuth, iron, chromium, and oxygen. These multiferroic materials absorb solar radiation and possess unique electrical and magnetic properties.
The loss of eyesight, often caused by retinal degeneration, is a life-altering health issue for many people, especially as they age. But a new development toward a prosthetic retina could help counter conditions that result from problems with this crucial part of the eye.
Chemists have succeeded in twisting a molecule by combining molecular strands of differing lengths. The longer strand winds around a central axis like a staircase banister, creating a helical structure that exhibits special physical properties.
Researchers showed it is possible to create an electrical channel a few atoms wide within two-dimensional insulating materials. Their simulations open new perspectives for the production of new electronic and photovoltaic devices.
Designkriterien für nachhaltige Nanomaterialien (DENANA) - so heisst das neue Verbundprojekt, das das Bundesministerium für Bildung und Forschung in den kommenden drei Jahren mit über 3,2 Millionen Euro foerdert.
