Researchers at the University of Massachusetts Amherst in the US have succeeded in fabricating organic photovoltaic (OPV) devices from water-based dispersions of polymer nanoparticle spheres using an innovative technique that allows them to control component assembly at different length scales. Devices made using the new technique appear to be as good as those in terms […]

Researchers in California have measured the elastic properties of atomically thin heterostructures made from molybdenite and tungstenite for the first time. These new, technologically important 2D materials and their heterostructures could be ideal for making flexible optoelectronics and photonics devices…. http://nanotechweb.org/cws/article/tech/58302 In the lab Two-dimensional semiconducting transition metal 

Multilayers of tungsten selenide – a new, technologically important 2D material – can strongly emit light if strain is applied to them. This result, from researchers at the University of California and the Lawrence Berkeley National Lab, also in California, means that such strained structures might now be used in applications such as LEDs, lasers […]

Lead halide perovskites can be used as light-emitting semiconductors in an LED structure, according to new experiments by researchers at the universities of Cambridge and Oxford in the UK and at the Ludwig-Maximilians-University in Munich, Germany. The light emitted by the perovskites can be easily tuned – something that could make the devices ideal for […]

Gene therapy can offer an effective treatment for drug-resistant radio-insensitive cancer. However, progress has been hampered by the difficulties in developing an appropriate delivery mechanism. Now researchers have demonstrated for the first time that magnetic nanoparticles provide safe, effective and targeted “suicide-gene” delivery to cells of a particularly prevalent and highly resilient type of liver […]

A new solar cell made from carbon nanotubes (CNTs) that is nearly two times better at converting sunlight into power than the best previous such cells has been unveiled by a team of researchers in the US. The National Renewable Energy Laboratory (NREL) has already independently certified the performance of the device – a first […]

A nanogel of a naturally occurring anticancer compound called triptolide coated with folate could be used to treat hepatocellular carcinoma, the most common form of primary liver cancer. So say researchers from Korea and Singapore who have found that the compound can be selectively taken up by tumour cells and once there lose its coating, […]

Silicene, a two-dimensional honeycomb lattice of silicon atoms with similarities to graphene, has attracted interest both in terms of the fundamental physics behind its properties and new technologies that might exploit them. However, a stable form of the material has proved elusive, making it hard to pin down its characteristic properties and possible applications. Now […]
