Feb 24, 2023 (Nanowerk News) An unusual form of caesium atom is helping a University of Queensland-led research team unmask unknown particles that make up the Universe. Dr Jacinda Ginges, from UQ’s School of Mathematics and Physics, said the unusual atom – made up of an ordinary caesium atom and...
A new approach to stabilise perovskite solar cells without lead
Feb 24, 2023 (Nanowerk News) Solar cells made from perovskite, a material that is able to harvest sunlight and convert it to electricity, hold great potential as a replacement for silicon solar cells. Despite superior performance, efficiency and being cheaper to manufacture, perovskite solar cells have not been commercially manufactured...
Quantum mechanics could lead to stronger, more sustainable alloys
Feb 24, 2023 (Nanowerk News) It may be an abstract concept for many people, but a new study shows that quantum mechanics can play a role in reducing the carbon footprint for producing steel and other alloys while making materials stronger and lighter. Researchers at KTH Royal Institute of Technology...
Breakthrough enables battery-free smart tag technology
Feb 22, 2023 (Nanowerk News) Imagine you can open your fridge, open an app on your phone and immediately know which items are expiring within a few days. This is one of the applications that a new technology developed by engineers at the University of California San Diego would enable....
Bacteria-growen nanowires can ‘smell’ a vast array of chemical tracers
Feb 23, 2023 (Nanowerk News) Scientists at the University of Massachusetts Amherst recently announced the invention of a nanowire 10,000 times thinner than a human hair that can be cheaply grown by common bacteria and tuned to “smell” a vast array of chemical tracers—including those given off by people afflicted...
Real-life ‘quantum molycircuits’ using exotic nanotubes
Feb 23, 2023 (Nanowerk News) Molybdenum disulfide MoS2 is a groundbreaking material for electronics applications. As a two-dimensional layer similar to graphene, it is an excellent semiconductor, and can even become intrinsically superconducting under the right conditions. It's not particularly surprising that science fiction authors have already been speculating about...
New analysis method developed for quantum and nanomaterials
Feb 23, 2023 (Nanowerk News) A slow-motion movie on sports television channels shows processes in hundredths of a second. By contrast, processes on the nanoscale take place in the so-called femtosecond range: For example, an electron needs only billionths of a second to orbit a hydrogen atom. Physicists around the...
Electrodes grown in the brain
Feb 23, 2023 (Nanowerk News) The boundaries between biology and technology are becoming blurred. Researchers at Linköping, Lund, and Gothenburg universities in Sweden have successfully grown electrodes in living tissue using the body’s molecules as triggers. The result, published in the journal Science ("Metabolite-induced in vivo fabrication of substrate-free organic...
