Scientist find ways to cut nanoparticle toxicity levels

Bioengineers and biophysicists from the National Research Nuclear University MEPhI, the Sechenov First Moscow State Medical University, the Universite de Reims Champagne-Ardenne in France, and the University of Tubingen in Germany have discovered that the toxicity of nanoparticles depends more on their size and the extent to which their surface area is charged than on […]

Meeting on “Perovskite Solar Cells-Towards Commercialization”

Ministry of Science and Technology (MOST), NANOTEC (a member of NSTDA) and SCG Chemical Company Ltd organized the meeting on “Perovskite Solar Cells-Towards Commercialization” on 9 October at Queen Sirikit National Convention Center (QSNCC) in Bangkok. The aim of the meeting is to exchange knowledge and promote research on Perovskite Solar Cell for commercialization. Speakers […]

Nanosheet inks offer new route to flexible electronics

Printed electronics are viewed as a cost-effective and scalable route to new technologies, although the performance of these devices tends to rely less on the printer and more on the ink. Researchers at Trinity College Dublin, in collaboration with scientists at Delft University of Technology and Toyota Motor Europe, have now fabricated vertically stacked thin-film […]

Engineered quantum dots convert low-intensity IR light into visible light

Auger up-conversion processes can allow photovoltaic devices to harvest low-energy solar photons that are not normally absorbed. A team of researchers from the Los Alamos Laboratory in New Mexico in the US has now demonstrated such a process in thick-shell lead selenide/cadmium selenide semiconducting quantum dots in which two low-energy, core-based excitons (electron-hole pairs) are […]

‘Butterfly’ magnetoresistance seen in nonmagnetic Dirac material

Researchers in the US and Germany have observed an unusual “butterfly”-shaped and extremely large angular magnetoresistance in the nonmagnetic Dirac material zirconium silicon sulphide (ZrSiS) that they can control using an applied magnetic field. The new findings could help in the development of “fermitronic” devices for high-speed electronics and optics……. http://nanotechweb.org/cws/article/tech/67344 Stuart Parkin

Researchers Develop Simple Method for Producing Fluorescent Carbon Quantum Dots from Sugarcane Bagasse

Indian researchers pioneer an alternate use for sugarcane waste. This schematic representation illustrates the process of turning bagasse into carbon quantum dots. (Credit: Elsevier) From Britain to Mexico, countries are considering sugar taxes to reduce consumption and curb the global obesity epidemic. In 2014, about 600 million people, roughly double the population of the United […]

Semiconducting polymers could make good e-skin

Researchers at Stanford University in the US have developed new, stretchable and self-healing thin-film polymeric semiconductors. The materials, which contain dynamic intermolecular hydrogen bonds that can be easily broken and reformed, might be used to make advanced organic electronic films that mimic human skin….. http://nanotechweb.org/cws/article/tech/66996 An intrinsically stretchable and healable organic semiconductor
