How dissolved black carbon moves electrons
2+ day, 17+ hour ago (102+ words) image: Electron transfer kinetics and molecular structural basis of dissolved black carbon as an electron shuttle view more Credit: Image Credit: Yufei Wu, Peng Zhang, Hanxue Li, Ting He, Wenmei Tao, Zhaofeng Chang & Bo Pan Tracking a Missing Kinetic Dimension…...
Dual‑ion co‑storage via solvation structure tuning toward ultrafast and durable zinc‑organic batteries
2+ day, 19+ hour ago (627+ words) Why This Electrolyte Matters KCl is introduced into a 2 M ZnCl2 aqueous electrolyte. The high concentration of KCl not only provides additional Cl⁻ ions but also fundamentally reorganizes the Zn2+ solvation environment and the hydrogen-bonding network of water. In the conventional ZnCl2 electrolyte,…...
Blue light boosts key medicinal compounds in Astragalus, study finds: Multi-omics and genetic tools uncover light-driven isoflavonoid biosynthesis
2+ day, 19+ hour ago (224+ words) EurekAlert! A working model illustrating how red and blue light promote isoflavonoid biosynthesis in the roots of A. mongholicus. Astragalus mongholicus, a cornerstone of traditional Chinese medicine, produces isoflavonoids—bioactive compounds with anti-inflammatory, immune-boosting, and antiviral properties. However, the molecular machinery…...
Viologen-linked covalent organic frameworks: A charged and redox-active platform for functional materials
2+ day, 21+ hour ago (538+ words) Researchers from Shenzhen University and collaborating institutions have provided a comprehensive review of viologen-linked covalent organic frameworks (Vio-COFs) as an emerging class of charged and redox-active porous materials. With their unique combination of permanent positive charges, reversible viologen redox chemistry,…...
Ultrathin niobate sheets combine UV detection, imaging and two-wavelength information encoding
2+ day, 22+ hour ago (184+ words) Researchers at Wuhan University developed a molecular-sieve-assisted confined molten-salt route to grow 2.66 nm Na2Nb4O11 single-crystal sheets. Devices made from the material combined sensitive ultraviolet detection with millisecond response and stable cycling, and enabled UV imaging and proof-of-concept two-wavelength physical-layer information encoding....
Tailor-made nanopores: Vienna team shapes "white graphene" at the atomic scale
2+ day, 22+ hour ago (71+ words) Physics and chemistry unlock a wide range of applications through nanopore engineering image: A simulated microscopy image of hexagonal boron nitride with a circular pore surrounded by triangular ones. Darker circles correspond to individual boron and brighter circles to nitrogen…...
Assembly of 2D organic crystals into vertical heterostructures for tunable light emission
3+ day, 1+ min ago (348+ words) Researchers from Soochow University in China have developed a fast vapor-deposition strategy to fabricate twisted vertical heterostructures (TVHs) from two-dimensional organic crystals. By precisely controlling the deposition temperature through adjusting diffusion distance, the yield of vertical epitaxial structures is dramatically…...
Crystal structure evolution from SBF to SCBF via Ca2+ doping
3+ day, 10+ hour ago (68+ words) (IMAGE) EurekAlert! Schematic illustration showing how Ca2+ doping at the Sm3+ site widens the Fe-O-Fe bond angle and shortens the Fe-O bond length, improving electron transport and oxygen kinetics in the SCBF electrode material. Huang Lab, Xinjiang University News organizations may use…...
Molecular antennae make light-activated molecular switches more sensitive
3+ day, 12+ hour ago (169+ words) Many cutting-edge technologies rely on molecules that can be switched on and off with light, but making them respond efficiently to visible light without losing stability has long been a challenge. Researchers at Tohoku University, working with Heinrich Heine University…...
