Advanced Science, EarlyView.This work demonstrates a paradigm‐shifting strategy to simultaneously achieve broadband wavelength tunability and single‐mode control within a single perovskite microwire structure. Using a facile heating‐assisted solid–solid anion‐exchange strategy, we synthesized phase‐pure CsPbClxBr3‐x microwires that exhibit the widest reported continuous lasing ...

Advanced Science, EarlyView.This study demonstrates a Bi2WO6/SrBi2Ta2O9 heterojunction where light‐driven ferroelectric polarization reversal couples with persistent photoconductivity, enabling exclusive NO2 selective room‐temperature sensing. The device achieves a two‐order‐of‐magnitude sensitivity enhancement over an unpolarized device, a sub‐ppb detection limit, and robust ...

Advanced Science, EarlyView.A NIR‐II light‐activatable thermoelectric nanoreactor converts surface‐bound Cu2+ into bioactive Cu+ via directed electron flow. This spatiotemporally controlled reduction triggers potent cuproptosis and immunogenic cell death, eradicating primary tumors and, together with aPD‐1 therapy, suppressing metastases while establishing durable immune memory ...

Advanced Science, EarlyView.A programmable coupled‐resonator‐induced transparency (CRIT) platform is proposed, generalizing classical electromagnetically induced transparency (EIT) via a spinor representation. By utilizing dual‐channel gauge fields and universal unitary operations, this architecture enables dynamically engineered, reconfigurable slow‐light bands on a silicon ...

Advanced Science, EarlyView.Schematic diagram showing compressive stress triggers glycolytic reprogramming and lactate accumulation in macrophages. Lactate mediates TRAF6 lactylation at K171/K180 dual sites, which enhances its K63‐linked ubiquitination to activate the NF‑κB pathway and promote M1 polarization. This cascade drives orthodontic tooth movement (OTM) and alveolar bone
