Reenvisioning the De Mayo Reaction: A Boron‐Enabled Cycloaddition Approach
Angewandte Chemie, EarlyView.An oxa‐boracycle conformational lock strategy enables photocatalytic [2+2] cycloaddition to afford densely substituted cyclobutylboronates. The conformational constraint suppresses triplet relaxation and promotes productive bimolecular reactivity.

Advanced Science, EarlyView.This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Angewandte Chemie, EarlyView.H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates

Femtosecond Transient Absorption Spectroscopy on the Light-Adaptation of Living Plants
EPJ Web of Conferences, 2013 The photoprotection reaction of the photosynthetic system under excessive sun light has been resolved for the first time by femtosecond absorption spectroscopy from the visible to near-infrared in intact leaves of Arabidopsis thaliana.

Influence of cadmium on photosynthesis of Brassica campestris ssp. chinensis L
浙江大学学报. 农业与生命科学版, 2005 Effects of different concentrations of Cd on photosynthesis and chlorophyll fluorescence in Pakchoi (Brassica campestris ssp. chinensis L.) were studied in solution culture. The results showed that low concentrations of Cd (0.01, 0.1 mg/L) promoted plant

Advanced Science, EarlyView.Employing a digital single‐molecule activity tracker (dSMAT), this research demonstrates that high‐photon‐flux irradiation drives progressive oxidative scarring in polymerases. Unlike simple thermal denaturation, real‐time kinetic tracking dynamically visualizes enzymes degrading into multiple impaired subpopulations.

Advancing Energy Materials by In Situ Atomic Scale Methods
Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Dynamics of photosynthetic complexes in the thylakoid membranes from higher plants
, 2011 PhDPhotosynthetic machinery in higher plants is localised in the thylakoids enclosed in a chloroplast. To optimise and regulate the photosynthetic efficiency under different, rapidly changeable environmental conditions the dynamics of the thylakoid
