Symmetry Breaking of Molecules Triggered by Chiral Inorganic Nanostructures Without Organic Components

open access: yesAdvanced Science, EarlyView.
Chiral nano‐inorganics, free of organic chiral ligands, provide a novel platform to direct symmetry breaking in molecular systems, through inorganic‐to‐organic chirality transfer via enantiospecific inorganic–organic interactions, circularly polarized light, and electron spin‐driven enantiopreferential reactions governed by chiral‐induced spin ...

Current Approaches and Challenges in Advanced Oxidation Processes for Nanoplastic Degradation

open access: yesAdvanced Science, EarlyView.
This review explores recent progress in advanced oxidation processes (AOPs) for the degradation of nanoplastics (NPs) in water. It presents a comparative assessment of key AOP technologies and identifies current limitations in analytical methods and treatment efficiency.

Exosomal CMTM4 Induces Immunosuppressive Macrophages to Promote Ovarian Cancer Progression and Attenuate Anti‐PD‐1 Immunotherapy

open access: yesAdvanced Science, EarlyView.
In ovarian tumors with high CMTM4 expression, exosomes transfer CMTM4 to macrophages, upregulating ICAM1 and promoting M2 polarization via p65 nuclear translocation. This suppresses immunity by increasing PD‐1 and Tregs while reducing CD8+ T cells.

Organocatalytic C─O Bond Cleavage and Asymmetric Transformations via [1,3]‐Sigmatropic Rearrangement

open access: yesAdvanced Science, EarlyView.
A direct asymmetric strategy for fulfilling the functional group transfer by aryl ether cleavage and migration is developed, representing the first Brønsted base‐catalyzed asymmetric [1,3]‐sigmatropic rearrangement reaction. The resulting chiral benzofuran products generated through this strategy exhibit significant 3D‐dimensionality and demonstrate ...

Magnesium‐Mediated Electrochemical Synthesis of Ammonia

open access: yesAdvanced Science, EarlyView.
This study demonstrates a lithium‐free, magnesium‐mediated electrochemical process for converting nitrogen (N₂) to ammonia (NH₃) under mild conditions. Using abundant materials, the system achieves ≈27% Faradaic efficiency at lower voltages than Li‐ and Ca‐mediated systems.
