Researchers at Rice University in the US have built a new supercapacitor based on a 3D nanoporous nickel hydroxide thin film.

The “hot electron photothermoelectric” effect in graphene could be exploited to detect terahertz radiation, according to new experiments by researchers in the US and Australia. A new device based on this effect is as sensitive as the best THz radiation detectors available today but it is a million times faster….. http://nanotechweb.org/cws/article/tech/58559 How to make a […]

Nanostructured ceramic materials have already been shown to be stronger and stiffer than bulk ceramics, but their brittleness has remained a major problem that can lead to catastrophic failure. Now, a team of researchers at the California Institute of Technology have successfully produced a structural ceramic metamaterial offering ultralow density along with high strength and […]

Researchers at the King Abdullah University of Science and Technology in Saudia Arabia are continuing with their experiments to transform traditional rigid electronic wafers made from silicon into mechanically flexible and transparent ones. In their new work, they have succeeded in transforming silicon-on-insulator (SOI) FinFETS (the semiconductor industry’s most complex transistor) into flexible FinFETs using […]

Metal nanoclusters, also known as plasmonic oligomers, could be used as efficient “Fano resonance-based” biosensors and for detecting and identifying single molecules. So say researchers in the UK, Germany, Singapore and Hong Kong who have studied the behaviour of plasmonic pentamers and quadrumers that have been functionalized with nanometre-thick alkanethiol monolayers. The oligomers interact with […]

Researchers in the US and the UK have succeeded in synthesizing high-quality 2D semiconductor heterojunctions between monolayers of molybdenum selenide and tungsten selenide – two new and technologically important materials. The junctions are the 2D analogues of epitaxial 3D semiconductor heterostructures, which make up most modern light-emitting diodes, lasers and high-speed transistors…. http://nanotechweb.org/cws/article/tech/58453 WSe2-MoSe2 heterostructures

Recent experimental observations of nucleation, the point where a solid first forms, contradict the predictions of classical nucleation theory. As a result uncertainty exists over a number of possible mechanisms for the formation of crystals from liquids. Now a team of researchers have used transmission electron microscopy to observe the formation of the mineral calcium […]

Devices made from resonating graphene “drums” could be used as sensors in applications such as mobile phones and also as memory chips in quantum computers. So say researchers at the Kavli Institute of Nanoscience at the Delft University of Technology in the Netherlands whose resonator works using a phenomenon called optomechanical induced transparency….. http://nanotechweb.org/cws/article/tech/58477 The […]

Cadmium telluride nanocrystal colloids could be used as the photovoltaic “ink” in solar cells, according to new experiments by researchers at the National Renewable Energy Laboratory and the University of Chicago. Devices made using CdTe layers as thin as just 330 nm have a sunlight-to-power conversion of efficiency of 10% while those made with 550 nm thick […]
