The design of novel materials with superior characteristics by entropy stabilization is a very dynamic emerging research area in materials science. However, despite recent advances in entropy-stabilized metals and insulating ceramics targeted for structural applications, there is still a dearth of high-entropy semiconductors, which poses a major obstacle for the adoption of high-entropy materials in semiconducting functional applications. Our study aims to realize a novel class of the semiconducting entropy-stabilized chalcogenide alloys.
A material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing -- and potentially exploitable -- conductive properties. University of Texas at Dallas physicists are studying how the ability of twisted bilayer graphene to conduct electrical current changes in response to mid-infrared light.
Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have demonstrated a record setting quantum protocol for sharing a secret amongst many parties.
Scientists at the Max Planck Institute of Microstructure Physics have discovered one of the largest anomalous Hall effects (15,506 siemens per centimeter at 2 Kelvin) ever observed in the new compound, KV3Sb5. This material has a never-before-seen combination of properties: Dirac physics, frustrated magnetism, 2D exfoliatability, and chemical stability. Aside from future fundamental research studying the interplay of these ingredients, the unique combination has potential for next-generation computing technologies like spintronics and quantum computing.
A Nagoya University team has developed a new method of synthesis for three-dimensional nanocarbons, utilizing a catalytic reaction to connect benzene rings and create an eight-membered ring structure. This represents a breakthrough in the synthesis of these nanocarbons, which are expected to be valuable next-generation functional materials.
Tungsten atoms are seen to come together in a way that is similar to an outer space ion. The finding suggests many more types of electron sharing between atoms could exist in nature.
Prof. WANG Guanghui and Prof. JIANG Heqing from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. LIU Jian from the Dalian Institute of Chemical Physics (DICP) of CAS, recently proposed a nanoreactor strategy for scalable synthesis of the supported ultrafine bimetallic nanoparticles (BNPs).
A Chinese-Australian collaboration has demonstrated for the first time that interlayer coupling in a van der Waals (vdW) material can be largely modulated by a protonic gate, 'injecting' protons into the device. The same weak interlayer forces that make vdW materials so easy to separate (eg, the famous Scotch-tape method of isolating graphene) also limit these materials' applications in future technology. Stronger interlayer coupling would significantly increase these materials' potential uses.
Kyoto University researchers develop a safer and more efficient way to produce dicarboxylic acid. Using an iridium catalyst bound to a bipyridonate ligand, researchers were able to synthesize dicarboxylic acids from aqueous diols, with the added benefit of generating hydrogen as a byproduct.
"Core-shell" clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient.
