Jul 04, 2023 (Nanowerk News) A research group led by Professor Minoru Osada at the Institute for Materials and Systems for Sustainability (IMaSS), Nagoya University in Japan, in collaboration with NIMS, has developed a nanosheet device with the highest energy storage performance yet seen. Their results were published in Nano...
3D printing biodegradable sensors and displays with nanomaterials
Jul 04, 2023 (Nanowerk News) An elastic material that changes color, conducts electricity, can be 3D printed and is also biodegradable? That is not just scientific wishful thinking: Empa researchers from the Cellulose & Wood Materials laboratory in Dübendorf have produced a material with these exact properties on the basis...
Unlocking quantum potentials with Rydberg moire excitons
Jul 04, 2023 (Nanowerk News) Rydberg states occur in a range of physical systems including atoms, molecules, and solids. In particular, Rydberg excitons, which are highly energetic electron-hole pairs, were first found in the Cu2O semiconductor material in the 1950s. Recent research published in Science ("Observation of Rydberg moiré excitons")...
Researchers create CO2 measurement tool to calculate emissions caused by digital data
Jul 04, 2023 (Nanowerk News) A unique carbon footprint tool has been created to allow businesses to measure the CO2 output of their digital data ("Is there a role for knowledge management in saving the planet from too much data?"). Each day, the average person creates 10 DVDs-worth of data...
Targeted control of growth dynamics of tin nanocoatings
Jul 04, 2023 (Nanowerk News) Nanometer-scale coatings with functional materials play an important role in many sensory, electronic and photonic applications. An international team of researchers – coordinated by Leibniz IPHT in Jena, Germany – has succeeded for the first time in observing novel growth effects of tin coatings on...
Laser-based method could help scientists discover new puncture-resistant materials
Jul 03, 2023 (Nanowerk News) A bullet piercing the protective armor of a first responder, a jellyfish stinging a swimmer, micrometeorites striking a satellite: High-speed projectiles that puncture materials show up in many forms. Researchers constantly aim to identify new materials that can better resist these high-speed puncture events, but...
Cutting edge transistors for semiconductors of the future
Jul 03, 2023 (Nanowerk News) Transistors that can change properties are important elements in the development of tomorrow’s semiconductors. With standard transistors approaching the limit for how small they can be, having more functions on the same number of units becomes increasingly important in enabling the development of small, energy-efficient...
Quasar ‘clocks’ show Universe was five times slower soon after the Big Bang
Jul 03, 2023 (Nanowerk News) Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein’s expanding universe. Einstein’s general theory of relativity means that we should observe the distant – and hence ancient – universe running much slower...
Astrophysicists propose a new way of measuring cosmic expansion: lensed gravitational waves
Jul 03, 2023 (Nanowerk News) he universe is expanding; we’ve had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate. It’s no small feat to measure the rate at which objects move away from each other...
An unexpected antenna for nanoscale light sources
Jul 03, 2023 (Nanowerk News) The fast switching and modulation of light is at the heart, among other things, of modern data transfer, in which information is sent through fibre optic cables in the shape of modulated light beams. It has been possible for several years now to miniaturise light...
