Recent Advances in Mediator and Proton Relay Usage in Molecular Catalysis

Advanced Science, EarlyView.
The use of electron–proton transfer mediators, redox mediators, and proton relays in synergy with molecular catalysts in energy‐related small‐molecule and organic transformations is discussed, with a focus on recent advances. Linear free‐energy relationship and catalytic Tafel plots provide a systematic foundation for benchmarking these catalytic ...

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

Advanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

Dual‐Site Synergistic Mechanism via Single‐Atom and Vacancy Drives Lattice Oxygen Activation in Layered Double Hydroxides

Advanced Science, EarlyView.
A strategy utilizing high‐energy ion beam technology to engineer defects in layered double hydroxide (LDH) nanosheets enables the high loading of non‐noble metal Mo single atoms. The synergistic effect between oxygen vacancies and single atoms promotes a novel mechanism for lattice oxygen activation, thereby significantly enhancing the oxygen evolution
