- 'Magic wand' reveals a colorful nano-world 30/12/2021 Researchers describe a revolutionary imaging technology that compresses lamp light into a nanometer-sized spot. It holds that light at the end of a silver nanowire like a Hogwarts student practicing the 'Lumos' spell, and uses it to reveal previously invisible details, including colors, in nanomaterials such as carbon nanotubes.
- New layer-by-layer built inorganic-organic material enables optical switching of magnetic properties 28/12/2021 Materials chemists have developed a facile process for piling ultrathin inorganic and organic layers in a pre-designed manner into flexible room-temperature thin-film magnets, whose magnetic properties can be controlled with successive external light illuminations.
- Quantum confinement discovered in porous nano-photocatalyst 23/12/2021 Green hydrogen production from solar water splitting has attracted a great deal of interest in recent years because hydrogen is a fuel of high energy density. A research team discovered the quantum confinement effect in a photocatalyst of a 3D-ordered macroporous structure. The quantum confinement effect was found to enable hydrogen production under visible light. The findings offer an option for addressing energy and environmental challenges.
- Resolving the puzzles of graphene superconductivity 21/12/2021 A single layer of carbon atoms arranged in a honeycomb lattice makes up the promising nanomaterial called graphene.
- Estado fundamental da matéria visto pela 1ª vez ajudará a computação quântica 16/12/2021 Um novo estado da matéria foi observado em um estudo que pode ajudar os cientistas no aprimoramento dos computadores quânticos. Previsto em 1973 pelo físico Philip W. Anderson, o líquido de spin quântico é um estado fundamental de um determinado sistema de spins. Alguns candidatos a líquido de spin quântico já foram analisados, mas esta é a primeira vez que os cientistas estão seguros de que estão lidando com este estado da matéria.
- Predicting high temperature Bose-Einstein condensation of excitons 14/12/2021 National University of Singapore researchers have predicted that an exotic state of matter known as a Bose-Einstein condensate can exist at relatively high temperatures (around 50 K to 100 K) in systems comprising organic molecules on two-dimensional (2D) semiconducting materials.
- Machine learning solves the who's who problem in NMR spectra of organic crystals 09/12/2021 Solid-state nuclear magnetic resonance (NMR) spectroscopy—a technique that measures the frequencies emitted by the nuclei of some atoms exposed to radio waves in a strong magnetic field—can be used to determine chemical and 3D structures as well as the dynamics of molecules and materials.
- A new dimension in magnetism and superconductivity launched 07/12/2021 An international team of scientists has launched a new paradigm in magnetism and superconductivity, putting effects of curvature, topology, and 3D geometry into the spotlight of next-decade research.
- Scientists are one step closer to error-correcting quantum computers 02/12/2021 Multiple quantum bits were combined into one ‘logical qubit’ to detect mistakes
- Spintronics: Exotic ferromagnetic order in two-dimensions 30/11/2021 An international team has detected an unusual ferromagnetic property in a two-dimensional system, known as 'easy-plane anisotropy.' This could foster new energy efficient information technologies based on spintronics for data storage, among other things.
- ESR-STM on single molecules and molecule-based structures 25/11/2021 Scaling down information devices to the atomic scale has brought the interest of using individual spins as a basic unit for data storage. This requires precise detection and control of spin states and a better understanding of spin-spin interactions.
