Technology Update
Researchers in the US have succeeded in chemically assembling the electronic junctions between a 2D semiconductor (molybdenum sulphide) and graphene, and have made an atomic transistor with good properties. They have also assembled the heterostructures into 2D logic circuits, such as an NMOS inverter with a voltage gain as high as 70…………. http://nanotechweb.org/cws/article/tech/65627 The graphene–MoS2 […]
A 3D artificial scaffold network made from multi-walled carbon nanotubes (MWCNTs) could help locally “rewire” nerve tissue. This is the new finding from researchers in Italy and Spain, who say that the technology could be exploited as a neural interface to help repair nerve fibres after injury or disease……. http://nanotechweb.org/cws/article/tech/65631 3D carbon nanotube framework scaffolds […]
Although using catalysts in production leaves materials prone to impurities, with the extreme temperatures sometimes required for catalyst-free synthesis, their use has seemed unavoidable. Not according to BNNT, a company whose catalyst-free boron nitride nanotube synthesis at the whopping temperature of 4000 °C won this year’s NASA Invention of the Year Award…….. http://nanotechweb.org/cws/article/tech/65309 Production engineer […]
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) […]
