Apr 12, 2022 (Nanowerk News) Probing the world of the very, very small is a wonderland for physicists. At this nano-scale, where materials as thin as 100 atoms are studied, totally new and unexpected phenomena are discovered. Here, nature ceases to behave in a way that is predictable by the...
A new method for atomic-resolution electron microscopes
Apr 11, 2022 (Nanowerk News) Electron microscopy enables researchers to visualize tiny objects such as viruses, the fine structures of semiconductor devices, and even atoms arranged on a material surface. Focusing down the electron beam to the size of an atom is vital for achieving such high spatial resolution. However,...
Using AI to expand the quality and fairness of urban data
Apr 12, 2022 (Nanowerk News) The sparse and inconsistent availability of urban data is currently hampering efforts to manage our cities fairly and effectively – but this could be solved by exploiting the latest advances in artificial intelligence. Our cities are remarkably complex systems. Every day, they host countless numbers...
Intense laser light modifies the pairing of electrons
Apr 12, 2022 (Nanowerk News) Electrons form the bonds in molecules and play a decisive role in chemical reactions. In atoms and molecules, the electrons are arranged on a sequence of energy levels that are characterised by quantum numbers. For their occupation, the interaction of these electrons with each other...
World’s first LED lights developed from rice husks
Apr 12, 2022 (Nanowerk News) Milling rice to separate the grain from the husks, produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum...
Converting solar energy to electricity on demand (w/video)
Apr 11, 2022 (Nanowerk News) The researchers behind an energy system that makes it possible to capture solar energy, store it for up to eighteen years and release it when and where it is needed have now taken the system a step further. After previously demonstrating how the energy can...
Light-powered microbes are super-producing chemical factories
Apr 11, 2022 (Nanowerk News) Sharing is key to living in society, whether it’s toddlers sharing toys or nations sharing natural resources; but there’s no avoiding the fact that one side getting more means that the other side gets less. Now, researchers from Osaka University, in collaboration with the University...
Researchers obtain a bioactive and sustainable plastic material by reusing pineapple residues
Apr 11, 2022 (Nanowerk News) A group of researchers from the University of Alicante Department of Analytical Chemistry, Nutrition and Food Sciences has been working, since the end of 2021, on a project on development of natural bioaromas to increase the shelf life of fresh food and reduce food waste....
Protecting the human intestinal microbiome with synthetic biology
Apr 11, 2022 (Nanowerk News) Many of us have experienced our gut thrown off-balance as a result of an unavoidable antibiotic therapy. Antibiotics not only kill the pathogenic bacteria causing an infection, they also indiscriminately wreak havoc on the trillions of “good” bacteria making up the human microbiota. Known as...
Optical vortex crystals for photonic simulations of complex systems
Apr 11, 2022 (Nanowerk News) Water whirlpools, smoke rings, violent tornados and spiral galaxies are all examples of twists in fluids, although very different each other. Analogous twists, but in the realm of light, have been created by the research group coordinated by Antonio Ambrosio at the IIT-Istituto Italiano di...
