Technology Update
A stumbling block for developing flexible solar cells has been the need for a smooth growth substrate to ensure high device efficiency. While glass is readily available, smooth and non-porous, it is also brittle, which makes the flexible properties of the other materials in the device redundant. Now researchers at the Institute of Photonic Sciences […]
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 […]
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
NanoMet is measurement tool for converting images of nanoscale materials to quantitative size data. It includes modules for particle and fiber diameters, as well as a module for object areas…..
Nanotechnology manufacturers seeking ways to measure and analyze nanoparticles now have a simple, fast, accurate and cost-effective tool thanks to the recent release of NanoMet by developer FullScaleNANO. ….. http://www.azonano.com/news.aspx?newsID=35207
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 […]
