Pure-red light-emitting diodes (LEDs) based on CsPbI3 quantum dots (QDs) have garnered considerable attention owing to their stable emission spectra and efficient electroluminescence. However, their operational stability presently lags far behind that of state-of-the-art perovskite LEDs. Here, we employ photoactive phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (PPO) molecules to resurface small-sized CsPbI3 QDs. The combination of sterically hindered PPO and small-sized methylacrylic acid (MA) ligands can comprehensively reduce uncoordinated Pb2+ on QD surfaces, which are related to nonradiative recombination. Moreover, the optimized QD films exhibit enhanced conductivity, showing more than 3.3-fold improvements over control QDs. Consequently, we demonstrate pure-red QD-based light-emitting diodes (QLEDs) with a maximum external quantum efficiency of up to 31.5% as well as a maximum luminance of 2434 cd m–2. More importantly, the photoactive PPO molecules release trimethylbenzoyl radicals under ultraviolet irradiation to further passivate newly generated defects in perovskites under operational conditions, thereby enabling the recovery of performance in aged devices. Based on this, we present QLEDs with an excellent operational stability (half-lifetime) of up to 300 h, representing one of the most stable pure-red perovskite QLED reported to date.

Lignin represents the most abundant source of aromatic compounds in nature, and its depolymerization holds great promise for yielding valuable aromatic products. Herein, we demonstrate the photocatalytic oxidative cleavage of β–1 bonds via the the Mars–van Krevelen (MvK) mechanism, and catalytic activity is achieved over lattice oxygen (OL)-rich WO3. A conversion of 99% is reached after reaction for 2 h under visible light, with the selectivity to benzaldehyde and benzoic acid reached 94%, surpassing the most reported catalytic systems. This photocatalytic performance stems from precise modulation of OL and oxygen vacancies (OV) sites in WO3, applicable to diverse β–1 model compounds and industrial lignin. In this MvK mechanism, the substrate adsorbs onto the OL sites, followed by activating the Cβ−H and inserting the lattice oxygen into the C–H bond to form a benzoin intermediate. Then, the desorbed benzoin undergoes a a Norrish Type I-like reaction, breaking the C–C bonds to form benzaldehyde. Concurrently, the adsorbed O2 at OV sites is reduced by photogenerated electrons, replenishing the depleted lattice oxygen and therefore manifesting stability (10 cycles). This in situ removal–regeneration strategy provides an approach for efficient lignin C−C bond cleavage and establishes the rational design principles for interfacial photocatalysts toward lignin valorization.

Organolead halide coordination polymers have emerged as promising photocatalysts owing to their attractive photophysical properties and structural tunability. However, organolead bromides typically exhibit limited photocatalytic performance due to their generally narrow light absorption range and inefficient carrier mobility. To overcome these issues, we designed and synthesized a robust layered organolead bromide coordination polymer templated by the squaric acid ligand featuring short carbon chains and broad near-UV absorption. It achieves visible light absorption and high charge separation efficiency, in contrast to the two reported lead bromide analogues with large interlayer spacing. Upon exposure to AM 1.5G simulated sunlight, the hybrid bromoplumbate exhibits enhanced photocatalytic activity for CO2–CO conversion, with high product selectivity and cycling stability. Moreover, the photocatalytic CO2 reduction performance is further promoted by in situ incorporation of trace Ag nanocrystals as reductive cocatalysts for suppressing carrier recombination, prolonging charge lifetime, and reducing free energy for the *COOH key intermediate. This work underscores the critical role of coordination chemistry in modulating the relationship between the structure and property of crystalline materials.

In this study, we describe a rationally designed light-inducible RNA-releasing protein (LIRP) capable of inhibiting mRNA translation in the dark while permitting gene expression upon exposure to blue or ambient light. This LIRP-dependent gene switch is compatible with various delivery routes of gene- and cell-based therapy, such as subcutaneous implantation of microencapsulated light-sensitive cells or expression in various light-accessible body sites using single adeno-associated virus (AAV) vectors. To exemplify a gene therapy approach that directly harnesses ambient light as a natural illumination source to induce therapeutic action, we show how intradermal delivery of AAV2 vectors carrying a LIRP-regulated gene switch controlling murine thymic stromal lymphopoietin expression was effective in enabling light-dependent prevention and treatment of diet-induced obesity. To describe another therapeutic scenario, we engineered AAV2 vectors for LIRP-dependent expression of Vascular endothelial growth factor (VEGF) inhibitors for the treatment of retinal neovascular diseases. Upon intravitreal delivery into mice suffering from wet macular degeneration, VEGF inhibitors were constantly produced when animals were exposed to daylight, but therapeutic actions could be flexibly interrupted either by exposure to dark environments or by administration of a selective blue light filter at any point in time. When compared to conventional treatment strategies based on constitutive VEGF inhibition over the course of 3 months, we show that a regulated gene therapy approach through LIRP-dependent optogenetics was advantageous in maintaining a normal retina thickness. This work not only provides a valuable addition to the optogenetic toolbox but also offers a perspective to translate light-dependent gene switches toward therapeutic usage.

The Ru/NiAl-LDH catalyst was designed for the selective hydrogenation of phenolic compounds under visible light irradiation and mild conditions (55 °C, atmospheric H₂), and it achieved 99% conversion of phenol with 99% selectivity to cyclohexanol. XPS and DFT calculations confirmed that Ni 2+ in the NiAl-LDH support donates electrons to the Ru center, creating an electron-rich Ru site that enhances H 2 activation. In situ DRIFT studies verified that visible-light irradiation promotes the heterolytic dissociation and adsorption of H 2 on Ru active sites. Additionally, surface hydroxyl groups on the NiAl-LDH facilitate phenol adsorption and concentration near active sites. The catalyst demonstrated broad applicability to substituted phenolic compounds and excellent recyclability over multiple cycles. The synergistic effect between the electron-rich Ru sites and the hydroxyl groups on the NiAl-LDH surface ensures highly efficient photocatalytic hydrogenation of phenol to cyclohexanol.

The high UV absorption of SiC and its large refractive index difference with photosensitive resin hinder fabrication via photopolymerization additive manufacturing. In this study, SiC powders were oxidized to form a SiC@SiO 2 core-shell structure, and two types of photoinitiators were combined to enhance the curing behavior of SiC slurries. Moreover, introducing polysiloxane into the resin further improved the curing ability and solid content. For fine SiC powders, slurries with up to 70 wt% solid content were successfully fabricated, achieving a curing thickness of 63 μm at 8 s exposure. Printed green bodies were pyrolyzed at 1100 °C, and SiC nanowires were in-situ formed. The resulting SiC@SiO 2 /SiOC ceramics exhibited a flexural strength of 157.8 MPa and an open porosity of 5.1%, among the highest reported values. The proposed methodology paves the way for the cost-effective production of high-performance SiC-based and other advanced non-oxide high-temperature ceramic components with high light absorption.

Perovskite light-emitting diodes (PeLEDs) are promising candidates for next-generation display and lighting technologies. However, conventional strategies for controlling morphology and crystalline structure often face challenges such as inefficient carrier transport and poor batch-to-batch reproducibility, primarily due to the presence of long organic ligands and the environment-sensitive nature of crystallization dynamics. Here, we present a localized micro-solvent field engineering strategy that simultaneously enhances device efficiency and reproducibility. By applying a nitrogen micro-gas flow, we obtain a clean nitrogen atmosphere and a lower substrate temperature for subsequent film coating. By incorporating low-boiling-point solvent acetonitrile into the precursor solution as a nucleation promoter, we precisely control the nucleation and growth kinetics. This synergistic approach, which avoids chemical hot-injection synthesis and insulating long-chain ligands, produces uniform quasi-quantum-dot perovskite films with the grain size (7–15 nm) approaching the exciton Bohr diameter with higher exciton binding energy. PeLEDs fabricated using this method demonstrate a peak external quantum efficiency of 33.79%, an average efficiency approaching 31%, excellent batch-to-batch consistency, and successful integration in pixel array devices. This strategy not only overcomes critical limitations in efficiency and reproducibility for solution-processed PeLEDs but also provides a broadly applicable framework to advance the performance and scalability of other perovskite optoelectronic devices.

Developing novel materials to improve the global food supply is vital to combat hunger, achieve food security and promote sustainable agriculture. To address this issue, we employed red-emitting Ag-In-S-Zn (AISZ) quaternary quantum dots (QDs) as light converters to fabricate AISZ QDs-loaded ethylene vinyl acetate (EVA) copolymers (AISZ/EVA) films to improve the light conditions for crop growth. The synthesis of AISZ QDs was optimized to achieve a high quantum yield (73%) and an emission band matching the absorption window of chlorophyll a and b. Using EVA resin as the matrix, efficient ultraviolet-to-red light-converting AISZ/EVA films with varying AISZ content were prepared by the solvent evaporation method. The fluorescence and transmittance of these light-conversion films along with a blank EVA control, were characterized. Subsequent 28-day lettuce cultivation under controlled light illumination revealed that the 1.0 wt.% AISZ/EVA film induced maximal growth enhancement. The fresh weight and dry weight were increased by 28.2% and 34.4%, respectively, while the contents of total chlorophyll, chlorophyll a, chlorophyll b, carotenoid, soluble sugars and proteins were increased by 48.8%, 51.3%, 43.8%, 40.8%, 33.6% and 37.2%, respectively. The results demonstrate that broad-emitting AISZ QDs served as efficient light converters to fabricate agricultural light-conversion films, highlighting their broad application prospects and promising commercial potential in controlled environment agriculture.

The geometric interplay in heterogeneous catalysis plays a crucial role in determining the catalytic performance. Based on the stronger affinity of Pd for ceria (CeO 2 ) than for titanium oxide (TiO 2 ) found in this work, we strategically engineered distinct Pd local environments by controlling the architecture of CeO x on TiO 2 through adjusting Ce content. At low Ce content, Pd preferentially assembles onto CeO x islands that are interspersed on TiO 2 ; while at high Ce content, Pd predominantly anchors onto the extensive CeO x surface. The former structure, enriched with CeO x -TiO 2 interface, exhibits superior capability in C-H bond cleavage and O 2 activation, leading to outstanding performance in the oxidation of carbon-containing gases such as light volatile organic compounds (VOCs; e.g., ethane and ethylene) and carbon monoxide (CO). In contrast, the structure dominated by continuous CeO 2 networks shows markedly lower activity. Combined analyses indicate that Pd 2+ species act as the primary active sites, and the consistent activity trend across differently Ce-modified catalysts in VOCs and CO oxidation can be explained by shared mechanistic steps, particularly through common CO and bicarbonate species intermediates. This work provides fundamental insight into the relationship between interfacial geometry and catalytic function.

Amino-density regulation was used to tune the electronic structure of UiO-67. • Diamino ligands induced electron redistribution between Zr nodes and linkers. • UiO-67-2NH 2 showed improved charge separation and interfacial transfer. • NO oxidation was enhanced while NO 2 formation remained at a low level. • Surface NO x intermediates were further converted into nitrate-related species. Functional group engineering of metal-organic frameworks provides a feasible route to tune their electronic structures, yet the specific role of amino ligands in regulating photocatalytic NO oxidation over Zr-based MOFs remains insufficiently clarified. Herein, UiO-67 derivatives with different amino densities were constructed through ligand engineering to investigate the relationship between ligand-induced electronic redistribution and visible-light-driven NO removal. Compared with pristine UiO-67, amino-functionalized UiO-67 exhibited enhanced visible-light absorption, improved charge separation, and reduced interfacial charge-transfer resistance. XPS and band-structure analyses suggest that the introduction of amino groups induces electron redistribution from Zr-oxo nodes toward ligand-related states, resulting in increased electron density near the valence band edge and more favorable photocarrier behavior. Among the prepared samples, UiO-67-2NH 2 showed the highest NO removal efficiency and maintained a relatively low NO 2 release during photocatalytic oxidation. ESR results confirmed the generation of •O 2 − and •OH under visible-light irradiation, while in-situ DRIFTS revealed the formation and evolution of NO + , NO 2 − , and nitrate-related intermediates. These results indicate that photogenerated carriers and reactive oxygen species jointly participate in the stepwise oxidation of NO toward more stable nitrate species. This work provides experimental evidence that amino ligand engineering can remotely modulate the electronic structure of UiO-67 and offers a useful strategy for improving the activity and selectivity of MOF-based photocatalysts for NO removal.

Through magnetic-field-assisted orientation printing, precise control of silver microplatelet orientation is achieved, resulting in a 23.3 μm improvement in linewidth precision and a 129.5% increase in curing depth. • Light-field finite element simulations reveal that oriented silver microplatelets suppress lateral light scattering while enhancing forward propagation, resolving the trade-off between resolution and curing depth in photocured metal pastes. • Despite the SPIONs-induced porous structure, the oriented silver microplatelets maintain good electrical performance, validated by a conformal antenna with measured results matching simulations, demonstrating their suitability for electronic circuit fabrication. The rapid miniaturization and increasing complexity of electronic components necessitate advanced manufacturing techniques capable of producing high-resolution conductive structures. Photocured printing technology, known for its high efficiency and exceptional resolution, holds great promise for fabricating cutting-edge electronics. However, the intrinsic constraints of the light-matter interactions make it challenging to achieve high-quality electrical circuits. Here, we report a magnetic-field-assisted orientation printing strategy that allows precise control of the orientation of silver microplatelets. This oriented alignment serves as the key to achieving programmable control of light penetration, which in turn improves printing quality. Compared with randomly oriented structures, the A90-oriented pastes exhibit a 23.3 μm enhancement in linewidth precision and a 129.5% increase in curing depth, facilitating the fabrication of circuits with simultaneously high resolution and thickness. Light-field simulations reveal that filler orientation directs incident light propagation, suppressing lateral scattering and promoting depth penetration. Furthermore, the electrical performance of the oriented silver microplatelets was systematically evaluated, and a conformal antenna fabricated on a silicon oxide substrate demonstrates good agreement between experimental measurements and simulated trends. This work demonstrates that magnetic-field-assisted orientation of anisotropic fillers provides an effective solution to the trade-off between printing resolution and curing depth in photocured metal pastes, enabling high-fidelity fabrication of functional electronic devices.

Uveitis poses a severe threat to vision and represents a critical clinical challenge. Conventional therapeutic approaches often exhibit limited efficacy in controlling disease progression and lack efficient mechanisms for managing localized oxidative stress. Given that molecular hydrogen (H 2 ) holds substantial promise for treating oxidative and inflammatory diseases via its selective antioxidant properties, we report a metal–organic framework (MOF) nanozyme-based hydrogen nanogenerator. This system integrates photocatalytic visible-light-triggered H 2 generation with multi-enzyme-like antioxidant functions for targeted uveitis management. The engineered Pt-embedded MOF nanozymes (Pt@MOF) concurrently catalyze hydrogen evolution under visible light and display superoxide dismutase- and catalase-like activities, achieving comprehensive scavenging of overproduced reactive oxygen species (ROS). Furthermore, camouflaging the nanozyme with M2 macrophage-derived cell membrane vesicles (CMVs) endows the nanoplatform with active inflammation-targeting ability, thereby enhancing the accumulation in inflamed ocular tissues. Following topical administration, this biomimetic nanomedicine successfully mitigates oxidative stress and suppresses pro-inflammatory cytokines both in vitro and in a rat model of acute uveitis. Overall, this study underscores the immense potential of integrating light-driven hydrogen therapy with nanozyme therapy, offering a highly effective strategy that could revolutionize future therapeutic interventions for inflammatory eye diseases.
