Near-infrared (NIR) light devices have great potential in non-destructive testing and biomedicine fields. However, the lack of stable and efficient long wavelength NIR phosphors hinders their development. In this work, utilizing the compositional flexibility of antimonate double perovskites, we realized efficient and tunable broadband NIR emissions based on A2MSbO6:Cr3+ materials (A = Ca, Sr, and Ba; M = Ga, In, Sc, and Y). The NIR emission peaks ranged from 825 to 1010 nm by a composition modulation. In particular, Ca2ScSbO6:Cr3+ exhibits an 850 nm-centering broadband NIR emission with an internal quantum efficiency of 84.5% and a high thermal quenching temperature, retaining ∼71% at 410 K of the initial intensity at 80 K. Comparatively, Sr2InSbO6:Cr3+ with a 920 nm-centering broadband emission has 63.2% internal quantum efficiency. This work could help in discovering novel NIR phosphors with long-wavelength emissions and high efficiency.

Aqueous Zn–Mn2+ electrolysis batteries utilizing the two-electron-transfer reaction between Mn2+ and MnO2 attract great attention because of their superior theoretical capacity (616 mAh g–1). However, the low conductivity of deposited MnO2 and the poor conversion efficiency of Mn2+/MnO2 inevitably result in limited areal capacity and unsatisfied cycling stability, which have become the main hurdles of aqueous Zn–Mn2+ batteries’ applications. Herein, we propose a novel Mn2+/I– hybrid cathode that couples the triiodide/iodide redox with the Mn2+/MnO2 redox to optimize the electrolysis kinetics. Because of the synergistically enhanced conversion reaction between Mn2+/I– and the promoter effect of I– to the dissolution of MnO2, this hybrid cathode not only exhibits fast reaction kinetics, thus demonstrating ultrahigh rate capability (100 mA cm–2), but also displays observably enhanced conversion efficiency up to 96.0% with excellent reversibility of 2000 cycles. Especially the superhigh areal capacity of 20 mAh cm–2 with more than 100 cycles among the reported static Zn–Mn2+ electrolysis batteries is demonstrated. The excellent battery performance as well as the facile electrode hybridization approach designed here paves the way for the practical applications of aqueous Zn batteries.

Formamidinium lead iodide (FAPbI 3 ) perovskite is a leading candidate for high-efficiency solar cells, but its application is hindered by the kinetic instability of its α-phase crystallization. Here, a highly effective strategy for directing the ordered crystallization of α-FAPbI 3 in the n-i-p architecture is developed by incorporating a self-assembled molecule (SAM) into the anti-solvent, unlike conventional phosphate-based SAMs requiring polar protic solvents, the -SCN SAM are processed from non-polar, aprotic solvents compatible with perovskite surfaces. An in-situ formed, self-assembled layer acts as a dynamic template, guiding the top-down crystallization process to yield highly ordered α-phase films. Through a series of in-situ measurements, it is rigorously demonstrated that this SAM treatment suppresses undesirable intermediate phases, accelerates the δ-to-α transition, and strategically slows crystal growth, promoting highly ordered films. This meticulously designed strategy culminates in high-quality perovskite films, enabling single-junction devices with a champion power conversion efficiency (PCE) of 26.18% (certified at 25.67%) and mini-modules with a PCE of 21.70%. These results underscore the power of directed self-assembly in fabricating highly efficient and stable n-i-p perovskite solar cells.

Near-infrared (NIR) luminescence capable of covering NIR-I and NIR-II is highly promising for biomedical imaging and non-invasive inspection. However, achieving both broadband and long-wavelength emission remains challenging due to the activator ion site-occupation constraints. In this work, we report La 3 TiGa 5 O 14 :Cr 3+ (LTG:Cr 3+ ) phosphor that exhibits an ultrawideband NIR emission spanning the spectral range of 650–1400 nm. The underlying mechanism involves Ti and Ga site exchange, which triggers local polyhedral reorganization. This structural transformation creates a weak crystal field, large Stokes shift, lower energy barrier of activator ion site occupancy, and more sites favorable for Cr 3+ incorporation ─ collectively relaxing Cr 3+ site-occupation constraints. The optimized LTG:0.03Cr 3+ phosphor exhibits NIR emission at 1017 nm with an exceptionally broad full width at half maximum (FWHM) of 476 nm. Moreover, introducing Ta 5+ as a charge-compensating dopant boosts NIR emission intensity by nearly 3.9-fold. A prototype NIR LED device fabricated with this phosphor demonstrates effective multi-channel signal detection. This work advances site-occupancy engineering from extrinsic doping to intrinsic polyhedral reorganization, providing a molecular design framework for high-performance NIR phosphor.

Two cationic functional woods with highly density nitrogen functional group are synthesized. • Q-BW and Gua-BW exhibit the fast uptake adsorption kinetics (within 5 min) of I - and IO 3 - through strong electrostatic interactions. • Gua-BW containing guanidine groups achieves roughly ten times the maximum IO3- sorption capacity of Balsa wood via electrostatic and redox. • Gua-BW, derived from renewable Balsa wood with low cost, displays excellent adsorption capacity and favorable reusability. Compared to conventional adsorbent carriers, Balsa wood (BW) has the superiority of being low-cost and environmentally friendly. Herein, quaternary ammonium-functionalized Balsa wood (Q-BW) and guanidine-functionalized Balsa wood (Gua-BW), as two cationic functional woods, are synthesized directly from natural Balsa wood via grafting high-density nitrogen-containing groups. The two modified woods exhibited remarkably high adsorption rates for I - and IO 3 - through electrostatic interactions, reaching adsorption equilibrium within 5 min. The maximum adsorption performance reached 120 mg·g −1 for I - and 220 mg·g −1 for IO 3 - , which was 10 times higher than that of natural Balsa wood. Notably, grafting with guanidino groups endows Gua-BW with redox ability, thereby significantly enhancing its adsorption performance for IO 3 - . Furthermore, Gua-BW demonstrates excellent reusability, retaining stable adsorption efficiency after 5 cycles. As a cationic porous wood material with ultrahigh positive charge density, Gua-BW possesses properties of being green, low-cost, renewable, and having significantly higher adsorption rates for I - and IO 3 - , which provides a new approach for applications in the field of iodine-containing wastewater purification.

Ergothioneine (ESH) is one of the most abundant antioxidants in the human body, but its biological functions remain unclear. In this work, we elucidated the detailed mechanism of the deactivation of divalent copper ions Cu(II) by ESH using optical spectroscopy, NMR, and LC-MS. We found that the reduction of Cu(II) ions to Cu(I) by ESH occurs in a bimolecular reaction of CuII(ES−)2complexes, leading to the formation of the disulfide ESSE. Cu(I) ions remain bound in stable complexes with ESH, preventing their reactions with molecular oxygen. Over longer timescales, ESSE decomposes, regenerating reduced ESH and forming the final reaction product, hercynine (EH). The conversion of one ESH molecule to EH causes the reduction of four Cu(II) ions. We determined the rate constants of the bimolecular reaction between CuII(ES−)2complexes to be k3= (8 ± 4) × 104M−1s−1and of ESSE hydrolysis to be k4= (1.7 ± 0.4) × 10−5s−1and also estimated the formation constant K12≈ 1.2 × 1017M−2for the CuII(ES−)2complex. The high efficiency of Cu(II) reduction and the chelation of the resulting Cu(I) ions in a stable complex supports the hypothesis that protecting cells from oxidation by metal ions is likely one of the main functions of ESH.

The solubility and thermodynamic profile of anastrozole (I) were comprehensively examined across diverse solvent systems through equilibrium gravimetric measurements conducted between 283.15 and 323.15 K under ambient pressure. The measured solubility of anastrozole (I) showed a positive correlation with temperature. Subsequently, the experimental data were correlated using four thermodynamic models, namely, the van’t Hoff, modified Apelblat, RK-4, and λh models. The results indicated that all models can reproduce the experimental data with high accuracy, among which the Apelblat equation exhibited a superior fitting performance compared with the other models. Then, thermodynamic analysis based on the van’t Hoff and Gibbs equations indicated that the dissolution process of anastrozole (I) is endothermic and enthalpy-driven in all the studied systems. Moreover, FT-IR, PXRD, and TG-DSC analyses indicated that anastrozole (I) possessed a stable structure during the solubility experiments. Furthermore, molecular simulation results supported the experimental observations by indicating that hydrogen bonding and dispersion forces play key roles in solute–solvent interactions. The dissolution behavior was dependent on solvent polarity and the solvation free energy.

The CsCu 2 I 3 /ZnO-heterojunction-based sensor enables H 2 S detection with a response value of 0.83 at 1 ppm, with response and recovery times of 240 s and 834 s. • The CsCu 2 I 3 /ZnO heterojunction improves structural stability and ensures continuous and stable sensor response. • The CsCu 2 I 3 /ZnO-heterojunction-based sensor achieves self‐calibration for different H 2 S concentrations with 99% detection accuracy. Hydrogen sulfide (H 2 S), a colorless and toxic gas, poses serious health risks upon prolonged exposure, including damage to respiratory and cardiovascular systems, which can be fatal in severe cases. Current H 2 S sensors suffer from limited response, particularly in detecting ultra‐low concentrations. To overcome this limitation, we developed a CsCu 2 I 3 /ZnO heterojunction‐based gas sensor via vacuum evaporation. This composite material enables highly responsive H 2 S detection at room temperature. The heterojunction not only improves structural stability but also ensures continuous and stable sensor response. At 1 ppm H 2 S, the sensor exhibits a sensitivity of 0.72, the response value of 0.83, the limit of detection (LOD) of 14.25 ppb, with response and recovery times of 240 s and 834 s, respectively. Furthermore, an intelligent calibration framework was developed by integrating Gramian Angular Summation Fields with the AlexNet algorithm, operating as a robustness enhancer. The sensor achieves self‐calibration for different H 2 S concentrations with 99.33% detection accuracy through 5-Fold Cross-Validation, significantly enhancing quantification capability. These results demonstrate the excellent potential of our CsCu 2 I 3 /ZnO-heterojunction-based sensor in H 2 S monitoring. The combination of responsive materials with machine learning offers a robust strategy for advancing ultra‐low concentration gas detection technologies.

Cellulose beads are produced through dissolution–regeneration processes that are solvent- and water-intensive and disrupt the native microfibrillar organization by converting cellulose I to cellulose II. Here, we establish a dissolution-free chemomechanical pathway that converts lignocellulosic biomass into spherical cellulose assemblies via architecture-governed cell-wall remodeling and shear-driven consolidation. Six feedstocks spanning agricultural residues (date palm, rice straw, corn straw, soybean straw) and woody biomasses (pine and peach wood) were subjected to sequential alkaline extraction, oxidative bleaching, and high-shear agitation. Comparative compositional, structural, and morphological analyses reveal that successful spheronization does not depend solely on cellulose content but requires the formation of a deformable continuity-preserving fibrillar intermediate. In this state, partial matrix removal induces wall swelling and delamination while maintaining load-bearing connectors that enable fibrillar bending, entanglement, and densification under hydrodynamic shear. Date palm and rice straw satisfy these criteria and produce stable cellulose I beads with fiber-assembled interiors. In contrast, corn and soybean residues undergo excessive fragmentation into fines that disperse as pulps/flocs, whereas pine and peach wood retain stratified, locked wall domains and yield irregular, rigid fragments. These findings establish an architecture-based mechanistic framework and selection rules for solvent-minimal, dissolution-free manufacturing of cellulose beads directly from low-value lignocellulosic biomass.

Fusarium head blight (FHB) is a devastating wheat disease
causing
yield losses and mycotoxin contamination. Phenamacril, a myosin I-targeting
fungicide, has a limited antifungal spectrum. Using structure-based
drug design focusing on M375 in Fusarium graminearum myosin I (FgMyoI), we synthesized 25 phenamacril derivatives. The II-2 emerged as the most potent inhibitor (EC 50 = 0.0077 mg/L against F. graminearum ), with broad-spectrum activity against various phytopathogens. Biochemical
and computational analyses confirmed that II-2 tightly
binds FgMyoI and inhibits its ATPase activity. In vivo tests demonstrated excellent protective and curative efficacy against
FHB in wheat and corn, while toxicity assays revealed low risk to
nontarget organisms. These results identify II-2 as a
promising myosin inhibitor and a novel candidate for FHB management.
This work also provides a foundation for the rational design of myosin-targeting
fungicides against diverse plant fungal diseases.

Drug repurposing has received increasing attention in the field of oncology drug development as an alternative strategy to de novo drug synthesis. Disulfiram (DSF) has a long history of clinical application in alcohol withdrawal, and recent studies have revealed that its metabolite diethyldithiocarbamate (DDTC) can be coordinated with copper ions in vivo to form Cu-DDTC complexes with anticancer activity. However, the insufficient in vivo stability of DSF remains a challenge. In this study, the nanomedicine Cu-BTC@DDTC with DDTC-Cu(I) chemical valence and polycrystalline structure was prepared by incorporation of DDTC into the nanosized metal–organic framework (MOF) Cu-BTC. The in vitro cellular evaluation results showed that Cu-BTC@DDTC exhibited high inhibition of tumor cell growth, migration, and invasion. Animal experiments on the xenograft tumor model further demonstrated the excellent antitumor activity and biosafety of Cu-BTC@DDTC, and the antitumor activity was found to be closely related to the regulation of the SLC7A11/GPX4 signaling pathway to induce ferroptosis. This study provides a feasible option for antitumor drug development based on a drug repurposing strategy.

Graphical The inclusion of carboxylic acid ligands significantly impacts the structural arrangement of the metal core in Cu(I) alkynyl clusters, thereby affecting their fluorescence properties. Furthermore, the incorporation of ferrocene into these clusters has been noted to induce modifications in the electrochemical performance of the Cu(I) alkynyl clusters. Surface ligands play a pivotal role in the functional design of atomically precise Cu(I) nanoclusters. They act as protective agents, ensuring the stability of the Cu(I) clusters, while also influencing their structure and properties. This study delves into the synthesis, structure, and properties of innovative Cu(I) nanoclusters co-stabilized by carboxylic acid and alkynyl ligands. The findings reveal that these surface ligands wield a significant impact on the cluster's structure and can even modulate the luminescent characteristics of the Cu(I) alkynyl clusters. Moreover, density-functional theory (DFT) calculations shed light on how different carboxylic acid ligands affect the UV-visible absorptivity of paired Cu(I) clusters. In addition, ferrocene carboxylic acids were employed as protective ligands to impart electrochemical properties to the Cu(I) clusters. This research presents an effective methodology for synthesizing atomically precise Cu(I) clusters shielded by carboxylic acid ligands.
