Using three-dimensional (3D) printing technology to make the porous tantalum plate and modify its surface. The physicochemical properties, cytocompatibility, antioxidant capacity, and histocompatibility of the modified materials were evaluated to prepare for the repair of craniomaxillofacial bone defects. The porous tantalum plates were 3D printed by selective laser melting technology. Tantalum plates were surface modified with a metal polyphenol network. The surface-modified plates were analyzed for cytocompatibility using thiazolyl blue tetrazolium bromide and live/dead cell staining. The antioxidant capacity of the surface-modified plates was assessed by measuring the levels of intracellular reactive oxygen species, reduced glutathione, superoxide dismutase, and malondialdehyde. The histocompatibility of the plates was evaluated by animal experiments. The results obtained that the tantalum plates with uniform small pores exhibited a high mechanical strength. The surface-modified plates had much better hydrophilicity. In vitro cell experiments showed that the surface-modified plates had higher cytocompatibility and antioxidant capacity than blank tantalum plates. Through subcutaneous implantation in rabbits, the surface-modified plates demonstrated good histocompatibility. Hence, surface-modified tantalum plates had the potential to be used as an implant material for the treatment of craniomaxillofacial bone defects.

Synergistic catalysis, where distinct active species collaboratively activate different substrates, provides a powerful strategy for achieving chemical transformations with enhanced efficiency. Although Al 2 O 3 and bulk aluminum species are widely employed as catalyst supports, they are seldom regarded as active centers, especially in hydrogenation. Here, we show that atomically dispersed Al species can catalyze acetylene conversion at elevated temperatures. Building on this insight, we have designed a synergistic catalyst featuring precisely controlled Al dual-atom sites paired with Ni nanoclusters, synthesized via a solid-transformation-coupled gas-adsorption strategy to overcome the typical activity-selectivity trade-off. Under mild, cost-effective conditions, this catalyst achieves nearly full acetylene conversion with ~90% ethylene selectivity and excellent long-term stability. In situ spectroscopy and theoretical calculations reveal a cooperative mechanism: Ni nanoclusters efficiently dissociate H 2 into active hydrogen species (H*), while adjacent Al dual-atom sites shuttle the H* species to π-adsorbed acetylene, lowering the energy barrier for ethylene formation compared to over-hydrogenation and coke formation.

Adopting compostable materials that return to nature akin to organisms can mitigate concerns regarding the ecological footprint associated with the widespread deployment of soft robots across various fields, including medicine, agriculture and environmental exploration. Nevertheless, current implementations are constrained by the lack of reliability of sustainable soft actuators, difficulties in achieving multifunctionality of biodegradable electronics, and uncertain eco-compatibility of by-products. Here we address these challenges by providing a framework that integrates sophisticated transient inorganic electronics with durable yet degradable elastomer (polyglycerol sebacate) and polyanhydride-based adhesive in compostable soft embodiments. Our soft electronic fingers withstand over 1,000,000 actuation cycles and feature 21 high-density electronic components that enable proprio-/exteroceptive sensing and environmental intervention. The high survival rates of oats germinated in soils containing feedstock composted from not only polymers but also electronic materials, such as Si, Mo and Mg, indicate that our robot is seamlessly integrated into the ecosystem. All these advances bridge the gap between sustainability and performance in soft robots.

Electronic transition/motion coupled with proton transfer has a key role in natural and artificial energy conversion and storage materials. Previous examples include proton-coupled electron transfer and singlet energy transfer, but not triplet energy transfer. Here we report a mechanism termed proton shuttle-assisted triplet energy transfer. The system comprises ZnSe-based quantum dots surface anchored with phenol–pyridine dyadic acceptors. Ultrafast measurements and kinetic isotope effects establish that the photoexcitation of ZnSe leads to hole transfer from ZnSe to phenol, which is coupled with proton transfer from phenol to pyridine. A subsequent step of electron transfer from ZnSe to phenoxyl radical, coupled with back proton transfer from pyridinium, accomplishes a net process of spin-triplet migration from ZnSe to phenol–pyridine. Adding a strongly electron-withdrawing trifluoromethyl substituent on pyridine can switch the sequence of proton-coupled electron and hole transfer steps. Compared with a methylated analogue acceptor lacking the shuttle, the assistance of proton shuttle substantially increases the energy transfer rate and efficiency.

Azole-linked covalent organic frameworks have drawn a lot of attention in photocatalytic synthesis of hydrogen peroxide, yet remain challenged by complex and costly synthetic routes. Here, we present a light-induced structural transformation strategy to facilely construct azole-linked covalent organic frameworks. We find that benzisoxazole linkages can be in-situ formed from imine linkages under light irradiation. As expected, the evolved partially benzisoxazole-linked covalent organic framework achieves a high hydrogen peroxide yield rate of 1986.9 μmol·g −1 ·h −1 in pure water. Theoretical calculations and spectral characterizations reveal significantly enhanced charge carrier separation and transfer efficiency, due to the formation of donor-acceptor structure. Furthermore, the in-situ formed benzisoxazole unit acts as both electron acceptor and catalytic center, promoting the reduction of dioxygen to superoxide radical, which is then converted into hydrogen peroxide, ultimately enhancing the yield. This work demonstrates a pioneering strategy for constructing benzisoxazole-linked covalent organic frameworks with high performance on hydrogen peroxide photo-synthesis.

Membrane materials and fabrication methods often need to be co-developed to meet the specific permeance and selectivity requirements of different gas separation application, which limits the adaptability of membrane technology. Here we propose a post-regulation strategy—adjusting the pore structures of a standard “primitive” membrane to meet various separation needs—that greatly simplifies membrane preparation and accelerates technological advancement. Graphene quantum dots (GQDs) are introduced as innovative building blocks: a continuous GQD membrane is constructed by tightly stacking GQDs, and then its pore structure is tuned via heat treatment and in-situ cross-linking with small amine molecules. Combining adjustable angstrom-scale pores with preferential CO 2 adsorption, the resulting GQD membranes exhibit widely tunable CO 2 /N 2 and CO 2 /CH 4 separation performances. The CO 2 permeance and separation factors surpass most reported membranes and can be tuned to exceed industrial targets for CO 2 capture. By varying the heat treatment temperature, the separation scope of the membrane is further extended to challenging gas pairs such as C 3 H 6 /C 3 H 8 , demonstrating the high potential of this customizable post-regulation pore structure strategy.

The intrinsic phase instability of CsPbI 3 perovskites necessitates stringent fabrication conditions, significantly hindering the practical deployment. In the DMA-mediated CsPbI 3 nucleation system, the Cs + /DMA + ion exchange critically governs the resulting film quality. Here, we employ a moisture-responsive crystallization strategy utilizing propyltriethoxysilane (PTES) to deposite CsPbI 3 under ambient air with high humidity (55%). We demonstrate that the siloxane groups can capture DMA + in the intermediate DMAPbI 3 , facilitating DMA + extraction and Cs + incorporation, thereby accelerating crystallization kinetics. This approach enables CsPbI 3 PSCs to achieve a power conversion efficiency (PCE) of 21.00% with an impressive fill factor (FF) of 86.1% while processing perovskite under relative humidity (RH) of 55%. Higher PCEs of 21.85% and 22.60% (certified 22.02%) were achieved for devices fabricated at a lower RH of 25% and for films spin-coated under an N 2 atmosphere followed by annealing in ambient air, respectively. Furthermore, PTES-treated devices exhibit excellent operational stability under ambient conditions.

Anisotropic materials with intrinsic one-dimensional architectures, where chains or tubes align along a crystallographic axis, exhibit direction-dependent optical responses and serve as ideal building blocks for polarization-sensitive optoelectronics. While progress exists in engineered compounds, discovering elemental crystals with naturally ordered one-dimensional building blocks exhibiting giant optical anisotropy remains challenging. Here, we report the synthesis of a direct-bandgap semiconducting one-dimensional phosphorus single crystal composed of unique wavy polygonal tubes. The monoclinic lattice structure is revealed by single-crystal X-ray diffraction and advanced transmission electron microscopy. The crystal exhibits giant birefringence in the visible and near-infrared regions, stemming from electron localization and anisotropic transitions of the phosphorus 3 p orbital along the tube axis. The low-symmetry structure endows remarkable linear and nonlinear optical anisotropies, including orientation-dependent photoluminescence, Raman scattering, and second-harmonic generation. This study establishes a paradigm for designing giant optical anisotropies, opening avenues for on-chip polarization devices and nonlinear photonic circuits.

Oxidative stress and excessive inflammatory responses are major drivers of atherosclerosis (AS) formation and progression. In this study, we report a nature-inspired nanoreactor (named USPB@SeDMSN@NM) with superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) multienzymatic activities for targeted atherosclerosis therapy. The confined cascade nanocatalyst (USPB@SeDMSN) is designed by assembling ultrasmall Prussian blue nanoparticles (USPB NPs, SOD and CAT mimics) into the large pores of selenium (Se)-doped dendritic mesoporous silica nanoparticles (SeDMSNs, GPx mimics). The DMSN provides abundant immobilization sites for USPB NPs and Se to sequentially scavenge reactive oxygen species (ROS) in a cascade manner and forms confined reaction environments to significantly increase the local concentration of substrates and overall catalysis efficiency, which is inspired by multienzyme complexes (MECs) in nature. The neutrophil membrane was coated onto USPB@SeDMSN to endow the nanoplatforms with the ability to target atherosclerotic plaques. In vitro and in vivo results demonstrated that this nature-inspired enzyme cascade nanoreactor efficiently mitigated inflammation in macrophages and endothelial cells by scavenging various radicals and inhibited foam cell formation by reducing lipid accumulation in macrophages. Moreover, it has significant antiaging effects, protecting DNA from oxidative damage and slowing the onset of cell senescence. By conducting confined SOD-CAT/GPx cascade reactions for high-efficiency plaque microenvironment modulation, the USPB@SeDMSN@NM nanoreactor offers a powerful modality for targeted atherosclerosis therapy. This work highlights the potential of this biomimetic confined nanoreactor with cascaded multienzyme-like activities as an antioxidant and antisenescence agent for atherosclerosis treatment.

The intrinsically low solubility of fatty alcohols in aqueous electrolytes imposes critical mass transport limitations for electrocatalytic oxidation. Conventional anodic electrocatalysts typically suffer from poor activity along with severe oxygen evolution reaction due to their hydrophilicity. Here, we present a ligand engineering strategy utilizing nickel-based metal-organic frameworks (Ni-MOFs) to construct hydrophobic microenvironments. Precise modulation of the aromatic structures of organic ligands promotes local enrichment of fatty alcohols and enhances structural robustness through π - π stacking interactions. Consequently, the optimized Ni-MOF exhibits enhanced activity for octanol oxidation compared to Ni(OH) 2 , achieving a threefold higher production rate and significantly improved Faradaic efficiency (84.7% versus 30.8%). The octanoic acid production rate is competitive with that of state-of-the-art thermocatalytic aerobic oxidation. This work highlights a general design principle for hydrophobic microenvironment to overcome mass transport barriers in organic electrocatalysis, demonstrating its potential for practical applications.

The nucleating agent 1,3:2,4-Bis(3,4-dimethylbenzylidene) sorbitol (DMDBS) improves the transparency of polypropylene (PP) but often induces yellowing. In this study, a complementary color strategy was employed by incorporating trace amounts of commercial blue dyes, including Acid Blue 74, Pigment Blue 15, and Pigment Blue 29, into DMDBS-nucleated isotactic polypropylene (iPP). Their effects on optical properties, mechanical properties and crystallization behavior were investigated. In terms of optical properties, all dyes effectively reduced the yellowness index (YI). Pigment Blue 15 exhibited the strongest effect by fully counteracting yellowing induced by DMDBS at only 5 × 10 − 5 wt%. Meanwhile, the dyes acted synergistically with DMDBS to reduce haze. Pigment Blue 15 and Pigment Blue 29 decreased haze from 32.3% to 21.3%. Regarding mechanical properties, Pigment Blue 29 showed the most pronounced synergistic effect with DMDBS, increasing the flexural modulus by 8.6%. Differential scanning calorimetry (DSC) and polarized optical microscopy (POM) results indicated that all blue dyes promoted the crystallization of DMDBS-nucleated iPP. Pigment Blue 15 exhibited the best performance, increasing the crystallization temperature by approximately 4 °C, and accelerating crystallization rates. Finally, analysis of the Avrami exponents (n) of iPP and nucleated iPP showed that the addition of dyes did not change the crystallization growth patterns of the nucleated iPP. This study provides a simple and efficient strategy to counteract the yellowing induced by DMDBS and enhance the transparency of the iPP, which shows great potential for industrial production.

Bacterial resistance, recurrent infections, and impaired wound healing pose significant challenges in clinical wound management. Natural biomass-derived carbon dots (CDs) have attracted considerable attention due to their synergistic antibacterial, anti-inflammatory, and biosafety, which facilitate the healing of infected wounds. In this study, carbon dots derived from Toona sinensis gum polysaccharide (TGP-CDs) were integrated into a gelatin-chitosan hydrogel to construct TGP-CDs@Gel. Experimental results demonstrated that TGP-CDs@Gel exhibits strong light-activated ROS generation capability, effectively disrupting bacterial biofilms and compromising membrane integrity through photodynamic antibacterial mechanisms. The composite also significantly promoted L929 fibroblast migration and protected RAW264.7 macrophages and N2 nematodes from oxidative stress. Importantly, TGP-CDs@Gel exhibited potent photodynamic antibacterial activity, as well as the regulation of pro-inflammatory cytokines and angiogenesis-related proteins (i.e., CD31, VEGF) in MRSA-infected wound, thereby significantly accelerating wound healing. Moreover, comprehensive biosafety evaluation confirmed its excellent biocompatibility across multiple models, including in vitro cell cultures, zebrafish, and nematodes. Collectively, TGP-CDs@Gel demonstrates promising photodynamic antibacterial and anti-inflammatory functions, providing a novel strategy for tissue regeneration and extending the application of Toona sinensis gum in biomaterials.
