Advanced Science, EarlyView.Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Advanced Science, EarlyView.A direct cascaded utilization strategy for spent LiFePO4 batteries efficiently extracts lithium from brine, embodying the “urban mining” concept. Phase fraction modulation revealed its significant impact on local bond lengths of crystal structure and the Li/Na diffusion energy barrier, identifying the best material (Li0.19FePO4) for lithium extraction.

Atroposelective Construction of Axially Chiral Tetraarylethenes Via NHC‐Catalyzed Desymmetrization
Advanced Science, EarlyView.We report the first NHC‐catalyzed atroposelective synthesis of axially chiral TAEs via oxidative desymmetrization of prochiral TAE dialdehydes. This catalytic strategy operates under mild conditions and accommodates a broad range of phenolic and nitrogen nucleophiles, delivering diverse axially chiral TAEs in good yields and up to 99% ee.
