Researchers in the US, Italy and Spain have developed a new technique to write fully reconfigurable magnetic nanopatterns in continuous multilayer films in which the magnetization can be oriented at will. The method allows magnetism to be controlled at the nanoscale in a way that was not possible before, and could be used to fabricate […]
Nanotechnology will be one of the highlight topics at the 25th NSTDA Annual Conference (NAC 2016) “The Power of R&D” which will take place from March 31 – April 1 at Thailand Science Park. A press conference chaired by Dr. Thaweesak Koanantakool, President of NSTDA was organized this morning at the Ministry of Science and […]
By embedding colloidal quantum dots in a high-mobility perovskite matrix, researchers at the University of Toronto in Canada and ShangaiTech University in China have succeeded in making a near-infrared (NIR) light-emitting diode (LED) with a record electroluminescence power conversion efficiency of nearly 5% for this type of device. The NIR LED could find use in […]
Tunable, flexible electronic and photovoltaic devices place some tough requirements on component materials. Recent reports of successful synthesis and characterization have suggested tungsten chalcogenides such as WS2(1–x)S2x could fit the bill, but to harness the properties of these materials in practical devices, stability is key. Now researchers have not only demonstrated tunable p-type electrical transport […]
A team of physicists in the US, Japan and Belgium say they have discovered a new way to control and guide electrons in graphene by removing a single carbon atom from its perfect honeycombed lattice. The vacancy produced can host a local charge and this charge can be built up gradually by applying voltage pulses […]
Graphene nanoribbons can slide across gold atoms without almost any friction, according to new experiments by researchers in Switzerland, Japan and Germany. Graphene’s superlubricity means that it could be used as an ultrasmooth coating in machine components, so drastically reducing energy losses in these machines. Nanoribbon coatings might also help to considerably increase the lifetime […]
Researchers in Moldova, Australia, the UK and Germany have developed a new way to improve the electrical and optical properties of gallium nitride by photoelectrochemically etching the material once it has been grown by a technique known as hydride vapour phase epitaxy (HPVE). Gallium nitride is a wide gap semiconducting compound and is the second […]
Polymeric nanoparticles called Accurins reduce the toxicity of a group of anti-cancer drugs known as aurora kinase inhibitors. So say researchers at Bind Therapeutics and AstraZeneca, who have used the nanoparticle formulation to treat colorectal tumours in rats. The technology might be extended to other small-molecule anti-cancer drugs……. http://nanotechweb.org/cws/article/tech/64049 Improving the balance of risks and […]
Encapsulating the chemotherapy drug irinotecan in lipid-coated silica nanocarriers could reduce its toxicity, according to new experiments by researchers at the University of California at Los Angeles. The strategy might be used to treat patients suffering from pancreatic cancer………. http://nanotechweb.org/cws/article/tech/64048 MSNPs deliver irinotecan
When a magnetic field is applied perpendicular to a graphene sheet, electrons in the material move in circular cyclotron orbits. These circular orbits have been imaged for the first time by researchers at Harvard University in the US and the National Institute for Materials Science in Japan. Imaging electron motion in this way could help […]
Researchers at the University of California at Berkeley and the Lawrence Berkeley National Lab have made the first high-performance and robust lasers from caesium lead halide nanowires that could be used in on-chip photonic and spectroscopic applications, such as optical communications, imaging and sensing. The lasing colour of the devices can also easily be tuned […]
