Oxygen Vacancy‐Rich S‐Scheme Heterojunction Photocatalyst With Enhanced Interfacial Charge Transfer for Round‐the‐Clock Formaldehyde Degradation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work addresses the critical challenges of severe charge recombination and the dependence on constant light illumination in photocatalysis. We propose a strategy centered on an oxygen vacancy‐rich S‐scheme heterojunction, which enables precise regulation of charge carrier behavior and achieves long‐lasting photocatalytic performance.

Programmable luminescent platform based on carbon quantum dots enables wavelength‐multiplexed optical data storage and encryption

open access: yesFlexMat, EarlyView.
A carbon‐quantum‐dots (CQDs)‐based programmable luminescent platform is proposed for multidimensional optical information encryption and high‐capacity data storage by leveraging wavelength‐division multiplexing. Furthermore, a prototype tri‐layer optical disk is demonstrated, where data written via laser ablation on different CQD layers are retrieved ...

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

open access: yesJournal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?
