Graphene flakes for future transistors

Tiny and very promising for possible applications in the field of nanoelectronics: they are the graphene nanoflakes. These hexagonal shaped nanostructures would allow to exploit quantum effects to modulate the current flow. Thanks to their intrinsic magnetic properties, they could also represent a significant step forward in the field of spintronics, which is based on the electron spin.

Laser-heated nanowires produce micro-scale nuclear fusion

Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. It’s also happening — at a smaller scale — in a lab. Using a compact but powerful laser to heat arrays of ordered nanowires, scientists have demonstrated micro-scale nuclear fusion in the lab. They have achieved record-setting efficiency for the generation of neutrons – chargeless sub-atomic particles resulting from the fusion process.

Scientists observe nanowires as they grow

Scientists have succeeded in monitoring the growth of minute gallium arsenide wires. Their findings do not only provide for a better understanding of growth, they also enable approaches to customizing nanowires with special properties for certain applications in the future. Gallium arsenide is a semiconductor material widely used in infrared remote controls, high-frequency technology for mobile phones, conversion of electric signals into light in glass-fiber cables, and solar cells for space technology.

Nanospears deliver genetic material to cells with pinpoint accuracy

In a step toward accelerating the production of new gene therapies, scientists report that they have developed remote-controlled, needle-like nanospears capable of piercing membrane walls and delivering DNA into selected cells. They say the new technique, which can ferry biological materials to cells with pinpoint accuracy, overcomes many of the existing barriers to effective gene modification.
