Scientists have demonstrated for the first time how electrons are transported from a superconductor through a quantum dot into a metal with normal conductivity. This transport process through a quantum dot had already been calculated theoretically in the nineties, but scientists at the University of Basel have now succeeded in proving the theory with measurements.
Scientists have developed a new catalyst material, graphene containing oriented metal nanoparticles, for organic reactions in the manufacture of drugs and pesticides. Aside from the material itself, the work's main contribution lies in the single-step process by which it is obtained.
By slipping springy polystyrene molecules between layers of tough yet brittle composites, researchers made materials stronger and more flexible, in the process demonstrating the theoretical limits of how far this toughening technique could go.
Scientists have developed a new method that can 'see' inside dispersed cubosomes (dispersed cubic liquid crystalline phases) with unprecedented detail. The breakthrough can help to improve their design significantly for better drug or nutrient delivery.
A new type of symmetry operation has the potential to quicken the search for new advanced materials that range from tougher steels to new types of electronic, magnetic, and thermal materials. With further developments, this technique could also impact the fields of computational materials design.
Scientists have also been able to steer this trapped light across the surface of the graphene, without the need for any nanoscale devices. This dual breakthrough opens up a host of opportunities for advances in pivotal electronic products, such as sensors and miniaturised integrated circuits.
The 2015 RUSNANOPRIZE Nanotechnology International Prize was awarded to Dr. Yury Gogotsi, Professor of Drexel University, Director of the Anthony J. Drexel Nanotechnology Institute and Dr. Patrice Simon, Professor of Paul Sabatier University.
Materials such as epitaxial graphene and MoS2, are films made of a few layers, with each layer only one atom thick. The films are characterized by strong in-plane bonds and weak interactions between the layers. Researchers used sub-angstrom-resolution indentations to measure the forces between the atomic layers.
