An expected effect, known as zero field switching, could enable lower-power memory and computing devices than presently possible.
A novel quantum effect observed in a carbon nanotube film could lead to the development of near-infrared lasers and other optoelectronic devices, according to scientists at Rice University and Tokyo Metropolitan University.
The Future Science Group (FSG) published journal, Therapeutic Delivery, today announced the release of its Special Focus Issue, which offers readers of the journal an insight into some of the recent developments, unanswered questions and future potential of nanotechnology in drug delivery.
UCLA scientists have developed a new method that utilizes microscopic splinter-like structures called 'nanospears' for the targeted delivery of biomolecules such as genes straight to patient cells.
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 Colorado State University laboratory. Using a compact but powerful laser to heat arrays of ordered nanowires, CSU scientists and collaborators 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.
Zero-emissions cars zipping into a sustainable energy future are just one dream powered by fuel cells. But cell technology has been a little sluggish and fuel prohibitively pricey. This new catalyst could offer a game changer. And there are more developments to come.
Scientists of Karlsruhe Institute of Technology (KIT) 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.
Javier Vela of Iowa State University and the Ames Laboratory has worked with two of his graduate students to synthesize a new material for semiconductors. The chemists think the material will work well in solar cells, but without the toxicity, scarcity or costs of other semiconductors. They report their discovery in a paper recently published online by the Journal of the American Chemical Society.
Tiny and very promising for possible applications in the field of nanoelectronics: they are the graphene nanoflakes studied by a SISSA's team and protagonists of a study recently published in the Nano Letters journal. 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.
In a step toward accelerating the production of new gene therapies, scientists report in ACS Nano 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.
