Technology Update
The 2014 Nobel Prize for Chemistry has gone to Eric Betzig, Stefan Hell and William Moerner for developing super-resolution microscopy techniques based on the fluorescence of molecules. The prize is worth SEK 8m (£690,000) and will be shared by the three winners, who will receive their medals at a ceremony in Stockholm on 10 December….. […]
Researchers in France have developed a new way to create cylindrical vector (CV) beams by electrically exciting a “plasmonic lens” with low-energy, tunnel electrons
Studying interactions between individual micromotors can help in understanding the fundamental principles of matter in dynamic steady states far from equilibrium.
Nanophotonic resonators attract interest for a range of potential applications and fundamental studies.
Researchers at the University of Toronto in Canada and Tsinghua University in China have made a solar cell based on n-type colloidal quantum dot “ink”
Researchers at the University of California at Los Angeles in the US and Hunan University in Changsha, China, have come up with a new way to grow 2D-layered semiconductor heterostructures
Graphene’s host of impressive attributes includes several properties that are ideal for sensing.
A new way to grow high-quality, wafer-scale graphene measuring between 100 and 300 mm across has been developed by researchers in the US and UK. The feat is a major advance since a size of 300 mm represents the silicon wafer-scale standard and means that the carbon material might now be easily integrated with silicon – a […]
Functionalized gold nanoparticles could be used to combat multi-drug-resistant pathogenic bacteria according to new experiments by researchers at the University of Massachusetts at Amherst. The nanoparticles can kill both Gram-negative and Gram-positive pathogens, including multi-drug-resistant strains while being non-toxic to mammalian cells. The particles do not induce bacterial resistance either – even after 20 generations….. […]
A new type of glucose sensor that works using a magnetically polarizable nanoemulsion could help change the way blood sugar is measured. The new device does not rely on glucose oxidase enzymes, unlike conventional glucometers, but instead simply changes colour when it comes into contact with glucose….. http://nanotechweb.org/cws/article/tech/58705 With and without glucose
Understanding how charge carriers (electrons and holes) behave at material interfaces is important for a number of energy-based technology applications such as fuel cells, batteries, electro- and photo-catalysts, and photovoltaic devices. Such applications rely on rapid charge transfer between these boundaries to drive energy-conversion processes. Now, a team of researchers at the University of California […]
Researchers in Japan have succeeded in making the first ionic atomic chain in which two chemical elements line up alternately
A new design for a cavity-free nanolaser has been proposed by physicists at Imperial College London
Researchers at the University of California at Berkeley and the Lawrence Berkeley National Laboratory are the first to have observed strong inter-tube coupling in “incommensurate” double-walled carbon nanotubes
Researchers at Rice University in the US have built a new supercapacitor based on a 3D nanoporous nickel hydroxide thin film.
Researchers in the UK, Russia and Korea say that they have made a new type of “quantum tunnelling” transistor from an ultrathin barrier of hexagonal boron nitride
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 […]
