Graphene: not just a geek gamble

Graphene FET Flagship is an ambitious European project to move graphene out of academic labs and into society, where its applications are expected to have a strong technological and economic impact. Jani Kivioja, a Finnish scientist, is leading the industrial activities within the project. His group looks to solve scientific challenges in order to transform the converging Internet and communications industry.

Surface plasmon resonance in interfaced heterodimers

A surprising enhancement was observed in this size regime when two different materials (silver and gold) were interfaced. Through theoretical modeling and quantum-mechanical calculations, quantum effects were determined to be responsible for this enhancement by creating a stronger condition for a "charge-transfer plasmon" resonance. The insight gained about this new mechanism may suggest general strategies for overcoming losses in plasmonic performance in the quantum size regime.

Cells' 'molecular muscles' help them sense and respond to their environments

Johns Hopkins researchers used suction to learn that individual "molecular muscles" within cells respond to different types of force, a finding that may explain how cells "feel" the environment and appropriately adapt their shapes and activities. A computer model the researchers developed also lets them predict what a cell will do in response to altered levels of those "muscles," a common occurrence in a variety of cancers.

Controlled arrangement of nanoparticles for improved electrical conductivity

Flexible displays, cost-efficient solar cells for a new era of energy production, futuristic lighting at home - all require thin layers with specific properties. Scientists at the Leibniz Institute for New Materials are exploring new routes to such coatings in NanoSPEKT, a project funded by the German Federal Ministry of Education and Research (BMBF).
