By making an optical cavity as small as just 40 cubic nanometres in volume, researchers in the UK have succeeded in mixing light with the optical transition of a single molecule placed inside the cavity so that the two become completely indistinguishable. Such intense cavity/single-molecule coupling could be used to probe the quantum properties of […]

Researchers at the University of Maryland have made the first flexible, solid-state membrane based on a 3D lithium-ion conducting ceramic nanofibre network. The membrane could replace conventional flammable organic liquid electrolyte systems in lithium-ion batteries…….. http://nanotechweb.org/cws/article/tech/65338 Solid-state electrolyte

Metal-free carbon-based electrocatalysts for dye-sensitized solar cells (DSSCs) are active enough in one type of commonly used (cobalt-based) electrolyte but not in another (iodide-based) one. Now, researchers at UNIST in Korea say they may have overcome this problem with their new catalyst made from edge-selenated graphene nanoplatelets, which has a high power conversion efficiency (PCE) […]

Researchers in Ireland have succeeded in making few-layer black phosphorus (a 2D semiconductor with a direct bandgap that stretches across the near to the mid-infrared) using a simple and scalable liquid-phase exfoliation technique. They have also measured how the material absorbs light. The near to mid-infrared wavelength region is becoming increasingly important for a wide […]

The replication of DNA involves conformational changes are that are greatly affected by its mechanical properties. Tethering DNA has profound effects on its mechanical properties, but there are few studies that attempt to quantify this change. Researchers at Virginia Tech have developed and refined a technique that allows high-sensitivity force measurements of dynamic systems, and […]

Single-crystal graphite appears to be a better contact material for graphene than conventional metals. So say researchers at Columbia University in New York who have found that the contact resistivity of the graphite–graphene interface can be as low as 6.6 Ωμm2. A reduced contact resistance could not only be useful for improving devices made from […]

Bringing together the best of two types of quantum computer for the first time, researchers at Google have created a prototype that combines the architecture of both a universal quantum computer and an analogue quantum computer. By digitizing the traditionally analogue computations that can be done with an adiabatic quantum computer, the team’s system is […]

Nanoparticles containing silencing RNA (siRNA) molecules could help reduce vascular inflammation after a heart attack and so lessen the risk of dangerous complications that might result. This is the new finding from researchers at the Massachusetts General Hospital (MGH) in Boston and the German Heart Center Munich, who have succeeded in supressing inflammation within atherosclerotic […]

Researchers at the Chinese Academy of Sciences in Beijing and the University of Cambridge in the UK have accidently discovered how to enhance the charge-carrier mobility in conjugated polymer thin films by simply adding an ionic additive. The new films, which have a hole mobility that is 24 times higher than those without the ionic […]

The handedness of individual chiral nanoparticles made of metallic dumbbells can be determined by their optical properties alone. So say researchers in Texas in the US and Donostia-San Sebastian in Spain, whose new work could help in the development of highly efficient miniaturized nanoscale sensors for studying the structure of chiral molecules and biomolecules like […]

The natural, high-strength glue found in English ivy is made up of nanospherical arabinogalactan proteins, according to new experiments by researchers at the Ohio State University in the US. The finding might help make artificial adhesives for military, medical and cosmetic applications……. http://nanotechweb.org/cws/article/tech/65147
