Nanowire solar cells raise efficiency limit

Scientists from the Nano-Science Center at the Niels Bohr Institut, Denmark and the Ecole Polytechnique Fédérale de Lausanne, Switzerland, have shown that a single nanowire can concentrate the sunlight up to 15 times of the normal sun light intensity. The results are surprising and the potential for developing a new type of highly efficient solar cells is great.

Scientists discover new nanotechnology technique to charge memory chips

IBM today announced a materials science breakthrough at the atomic level that could pave the way for a new class of non-volatile memory and logic chips that would use less power than today's silicon based devices. Rather than using conventional electrical means that operate today's semiconducting devices, IBM's scientists discovered a new way to operate chips using tiny ionic currents, which are streams of charged atoms that could mimic the event-driven way in which the human brain operates.

Researchers use metamaterials to observe giant photonic spin Hall effect

Researchers have once again demonstrated the incredible capabilities of metamaterials - artificial nanoconstructs whose optical properties arise from their physical structure rather than their chemical composition. Engineering a unique two-dimensional sheet of gold nanoantennas, the researchers were able to obtain the strongest signal yet of the photonic spin Hall effect, an optical phenomenon of quantum mechanics that could play a prominent role in the future of computing.

Innovative graphene technologies: Developments and characterisation

In order to collect vital information on graphene, this book is compiled in two volumes. Volume 1 is specifically meant for the beginners who want to understand the science and technology associated with the nanomaterial. The first objective of this book is to furnish detailed information on the manufacturing or syntheses of graphene and related materials in the lab without the need of special equipments. The chapters are written systematically so that it is easy to understand science, engineering and technology behind the material.
