Advanced Science, EarlyView.Rare‐earth catalysts regulate lithium–sulfur battery chemistry through f‐orbital–mediated interactions, enabling simultaneous polysulfide adsorption and catalytic conversion on conductive carbon hosts. This synergistic control suppresses the shuttle effect, accelerates redox kinetics, and guides stable Li2S nucleation, providing a mechanistic framework

Advanced Science, EarlyView.An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

Advanced Science, EarlyView.A ZnIn2S4–carbon dot heterojunction enables photocatalytic H2O2 production coupled with furfuryl alcohol oxidation. In this redox system, furfuryl alcohol acts as both the electron donor and oxidation substrate, producing furoic acid with 100% selectivity and 98% conversion while supporting efficient H2O2 generation with a solar‐to‐chemical conversion (

Sen'i Gakkaishi, 1984 Substituent effect on the ozonation of anthraquinones was discussed. Reactivity of anthraquinones with ozone increased as greater was the electron donative property of the substituent. When the unsymmetrical anthraquinones were ozonized, the remarkable selectivity of ozone attack on the both aromatic rings was observed.

The Direct Chlorination of Anthraquinone Oxime. The Regioselective Chlorination of Anthraquinone [PDF]
Bulletin of the Chemical Society of Japan, 1977 Abstract The reaction of anthraquinone oxime with chlorine in the presence or absence of a catalyst was investigated. In concentrated sulfuric acid, the direct chlorination of anthraquinone oxime takes place easily at 100 °C. The chlorination occurs selectively in the β-position in the absence of a catalyst and in the α-position in the ...
