Electronic and Steric Tuning of Molecular Acidity toward Unified Models for Excited State Proton Transfer

Advanced Science, EarlyView.
Conventional excited‐state proton transfer (ESPT) theories explain the kinetics of fluorescent photoacids, but face challenges for weakly or nonfluorescent ones. This missing link is bridged by making and dissecting series of green fluorescent protein chromophore derivatives with varied photoacidities via strategic substitutions. Structure‐photoacidity

Manipulating Spin States by Metal Axial Coordination of Active Sites for Generating Valuable CH4 in CO2 Reduction

Advanced Science, EarlyView.
By encapsulating Ni atoms into Mn zeolitic imidazolate framework‐8, the spin‐state transition of Mn 3d3 from low‐spin to high‐spin was facilitated upon Ni axial coordination via Mn 3d orbital splitting. This facilitates the electronic donation and induces the closing of Mn d‐band center toward Fermi level to strengthen *CO adsorption, thereby ...

Dual‐Emulsifier Coated Photocatalyst for H2O2 Synthesis in Emulsion via Water Oxidation

Advanced Science, EarlyView.
A dual‐emulsifier coated photocatalyst facilitates efficient synthesis of H2O2 in water and the hydrogenation in oil via water dissociation. Abstract Photocatalysis provides a sustainable approach for on‐site production of H2O2, yet single‐phase systems generally display unsatisfactory efficiency and low concentration of H2O2 due to rapid reverse ...

Molecular Assembly Unlocks Dual‐Defect Synergy in Carbon Nitride for Efficient H2O2 Photosynthesis

Advanced Science, EarlyView.
A long‐standing puzzle in making catalysts for hydrogen peroxide is broken. The innovation is a synthesis strategy that creates two synergistic defect sites (cyano defects and N vacancy defects). This synergy enables highly efficient and selective H2O2 production.

Leucine‐Dependent SLC7A5–PGAM5 Interaction Promotes Advanced Atherosclerosis Through Hindering Mitochondrial Function of Macrophages

Advanced Science, EarlyView.
Higher plasma leucine is associated with increased risk of new‐onset myocardial infarction. Leucine deprivation alleviates advanced atherosclerosis in mice. Tumor‐induced leucine deprivation reprograms macrophage metabolism and increases CD5Lhi macrophages in mouse plaques. Mechanistically, leucine deficiency reduced SLC7A5‐PGAM5 binding in macrophages,
