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.
Scientists unveiled an unprecedented spin relaxation mechanism unique to graphene, and related with entanglement of spin and pseudospin quantum degrees of freedom in presence of weak spin-orbit coupling effects. This phenomenon revisits years of controversies and opens a new window into the challenge of manipulating spin degree of freedom in future information-processing technologies.
Researchers have determined the microscopic origin of an unusual form of magnetic heat transport. The team reports on how magnetic 'quasi-particles', known as magnons, propagate in Lu2V2O7, the first material to exhibit the thermal magnon Hall effect: the magnetic transport of heat perpendicular to a temperature gradient.
