- Quest to deliver ultra-fast and energy efficient magnetic recording moves step closer 06/01/2022 The quest to deliver ultra-fast and energy efficient magnetic recording could be a step closer to fruition, due to pioneering new research on all-optical switching of magnetization.
- Toward achieving megatesla magnetic fields in the laboratory 04/01/2022 Recently, a research team at Osaka University has successfully demonstrated the generation of megatesla (MT)-order magnetic fields via three-dimensional particle simulations on laser-matter interaction. The strength of MT magnetic fields is 1–10 billion times stronger than geomagnetism (0.3–0.5 G), and these fields are expected to be observed only in the close vicinity of celestial bodies such as neutron stars or black holes. This result should facilitate an ambitious experiment to achieve MT-order magnetic fields in the laboratory, which is now in progress.
- '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.
