Superhydrophobic sponge materials offer a promising solution for treating oily wastewater. To address the challenges of hydrophobic modifier leaching and process complexity, this study developed a composite sponge by immobilizing hydrophobically modified mesoporous silica nanoparticles (H-DMNH) onto a polydopamine (PDA)-modified melamine sponge (MS) framework. Hydrophobic long-chain siloxanes were grafted onto the mesoporous silica nanoparticles (DMNH) via hydrothermal synthesis, and the resulting H-DMNH was firmly anchored onto the PDA coated MS sponge through electrostatic interactions, hydrogen bonding, and hydrophobic interactions. The obtained H-DMNH/PDA@MS sponge exhibits integrated and durable superhydrophobicity with a water contact angle (WCA) of 154°, antifouling properties, high oil absorption capacity (36.2–118 g/g), efficient separation of oil/water mixtures and emulsions (>97%), and good recyclability. Under simulated solar irradiation, the H-DMNH/PDA@MS sponge surface temperature rapidly rises to 65 °C within 1 min, achieving a photothermal conversion ability of 88.3%, thereby promoting adsorption through reducing oil viscosity. Furthermore, the H-DMNH/PDA@MS sponge shows certain flame-retardant characteristics (loss rate is 25.6%), which substantially enhance operational safety in flammable environments. With this multifunctional attribute, the H-DMNH/PDA@MS sponge emerges as a robust and sustainable material for practical oil-water separation applications.

Latent fingerprint visualization on complex substrates typically suffers from interference from background patterns and fluorescence. Carbon dots (CDs) with room-temperature phosphorescence (RTP) provide an effective route to eliminate background interference due to their long-lived emission. However, most fingerprint reagents based on phosphorescent CDs are limited to single ultraviolet (UV) lamp excitation, resulting in poor operational flexibility and restricted anti-interference performance on complex substrates. While visible light excitation is safer and more flexible, current visible-light-excited phosphorescent fingerprint powders require tedious multi-step preparation. In this study, CDs with alumina matrix (CDs@Al 2 O 3 ) composite emitting RTP under both visible and UV light excitation is synthesized in situ through one-step calcination. The prepared composite features visible RTP lasting for 12 s and 6 s to the naked eye after 365 nm UV and visible light excitation, respectively. With dual-mode excitation properties, the CDs@Al 2 O 3 is applied to imaging of latent fingerprints (LFPs) on various complex substrates. Additionally, background interference from different substrates is effectively eliminated by flexibly switching the light source, which significantly enhances the contrast and detail resolution of fingerprint images. This strategy simplifies the preparation procedure while greatly improving the applicability and reliability of latent fingerprint development in complex scenarios, providing a facile and versatile approach for background-free visualization of LFPs.

Co-loaded CNT with high Co 2+ content of 61.07% exhibited enhanced nanozyme activity. • P2 possessed a safe Co-ion release content far below the threshold of 20 ppm. • P2 exhibited good well-rounded properties and excellent anti-inflammatory activity. Excessive reactive oxygen specie (ROS) is not conducive to bone repair, which is prone to generate during the initial hematoma inflammatory phase following poly( L -lactic acid) (PLLA) bone scaffold implantation and the potential inflammation caused by its acidic degradation products. This study proposed introducing cobalt (Co)-based nanozyme into the PLLA scaffold, and focused on improving the dispersion between nanozyme and the PLLA matrix as well as enhancing the activity of nanozyme itself for efficiently scavenging ROS. The Co was loaded on the surface of carbon nanotube (CNT) for achieving uniform dispersion, and then calcined under different atmospheres for enhancing nanozyme activity via regulating the Co 2+ /Co 3+ ratio and optimizing the electronic structure. It was found that the nanozyme that was calcined in an N 2 atmosphere followed by phosphorylation exhibited a superior ROS-scavenging ability, which was attributed to its high Co 2+ content of 61.07% that facilitating the redox cycling and the optimization of its electronic structure by P doping. As a result, the composite scaffold (P2) at a nanozyme loading of 2 wt% possessed superior intracellular ROS-scavenging ability and downregulation of key inflammatory cytokines compared to the pure PLLA scaffold. It also possessed good cytocompatibility for cell adhesion and proliferation, and exhibited upregulated expression of the pro-angiogenic VEGF factor.

Light-driven micro/nanorobots (LMNRs) offer on-demand propulsion governed by light direction, wavelength, and polarization, yet their architectures and navigation behaviors have been constrained by limited fabrication strategies. Here, we present a general and scalable strategy for geometry-programmable silicon LMNRs based on plasma-enhanced chemical vapor deposition. This approach yields libraries of silicon microrobots with deterministically tailored 0D, 1D, 2D, and 3D geometries, greatly expanding the accessible design space. Under visible and near-infrared illumination, the LMNRs exhibit efficient propulsion and precise, light-programmable trajectories, with guidance further augmented by magnetic steering. Surface functionalization with bacteriophages imparts species-selective bacterial capture, enabling targeted biointeractions. By integrating structural programmability, multimodal actuation, and bioselective interfaces in a silicon platform, this work establishes a versatile foundation for multifunctional LMNRs, paving the way for micro/nanorobotic applications in precision therapy, environmental monitoring, and micro/nano-manufacturing.

Excessive back interface interdiffusion and absorber defects are the primary limitations to the performance of Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cells. In this study, we address these limiting factors by introducing an ITO interlayer at the back interface. During the initial stage of selenization, the ITO functions as a diffusion barrier, effectively suppressing the migration of metal elements toward the Mo electrode and thereby mitigating elemental loss. In the middle and final stages of selenization, the ITO acts as a self-sacrificing layer, supplying Sn and In elements to compensate for the absorber layer. The dual-functional ITO interlayer facilitates the redistribution of elemental composition within the absorber layer. It reduces Sn-related vacancy defects through supplemental Sn supply and alleviates Sn-related substitutional defects via trace In doping. Through the optimization in this work, the defects in the absorber layer were effectively reduced. The reverse saturation current density decreased from 4.14 × 10 −7 to 2.67 × 10 −8 A/cm 2 , indicating effective suppression of carrier recombination. Finally, the ITO-10 sample achieved a photoelectric conversion efficiency of 13.11%. This work presents a new interlayer material that reveals the synergistic mechanism of bulk doping and defect regulation in transparent conductive oxide ITO for CZTSSe.

Rechargeable zinc–air batteries (ZABs) are promising candidates for sustainable energy storage; however, their performance is severely limited by sluggish oxygen reduction and evolution (ORR/OER) kinetics. Here, a hard-templating etching strategy was employed to construct nitrogen-doped hollow mesoporous carbon spheres embedded with NiCo nanoparticles (NiCo@N-HMCS). The hollow nanostructure, together with a strong electronic coupling between NiCo alloys and N-doped carbon, provides abundant accessible active sites, optimized charge transfer, and robust structural stability. As a result, NiCo@N-HMCS delivers remarkable bifunctional electrocatalytic activity in alkaline media, with a half-wave potential of 0.84 V for the oxygen reduction reaction and an overpotential of 330 mV at 10 mA cm −2 for the oxygen evolution reaction. When applied in ZABs, the catalyst delivers a high open-circuit voltage of 1.56 V, a peak power density of 185.53 mW cm −2 , and durable cycling over 300 h. The flexible ZAB configuration also delivers a power density of 79.06 mW cm −2 and stable operation of 120 h. This study demonstrates a robust platinum-group-metal-free strategy for advancing next-generation rechargeable and flexible energy storage systems.

Transition metal-catalyzed C-C couplings have the potential to provide complex molecules, however, the formation of selective C–C bonds for symmetric/unsymmetric dihalogenated aromatics remains being a challenge. To explore the specificially selective Suzuki monocoupling of symmetrical/unsymmetrical dibromopyridines, a set of cross-linked cyclodextrin polymers ( CD-P ) were synthesized by CuAAC reaction and coordinated with Pd ( CD-P-Pd (II) ). Numerous cavities with pocket-like catalytic sites were designed in its structure and the narrow rims of cyclodextrin were connected and enclosed by triazole rings coordinated with Pd. Meanwhile, the wide rims were kept open to recognize the reactants and products for association and dissociation with the cavity. The use of CD-3-P-Pd (II) under mild conditions can obtain monosubstituted products with yield of up to 79% and specific selectivity (mono−/bis- = 100:0 for symmetrical dibromopyridines, monoaty−/monoty−/bis- = 80:0:20 for unsymmetrical dibromopyridines). This mechanism study supports the hypothesis that the first oxidation addition step can be effectively regulated by the structural design of the catalyst to obtain monosubstituted products. Cyclodextrin polymers offered exciting possibilities for the specificity of coupling reactions by facilitating host-guest recognition.

Developing high-performance Ni-based catalysts is critical for the practical application of dry reforming of methane (DRM). Herein, the 10wt%Ni/CeO 2 catalyst was mediated by CeAlO 3 formed by interfacial reaction between impregnated Al species and the CeO 2 support. The resultant CeAlO 3 has a significant influence on the structural properties and the catalytic performance. CeAlO 3 can enhance the dispersion of Ni, introduce more oxygen ion vacancies and medium basic sites, which contribute to the high activity and high coking resistance. Furthermore, the enhanced interaction between Ni and the support impedes the sintering of Ni nanoparticles, leading to improved stability. The sample with Al:Ce molar ratio of 0.1 demonstrates impressive performance, at 800°C and 120,000 mL/(h·g cat ), the CH 4 , CO 2 conversion and H 2 /CO ratio are 94.3%, 90.7%, and 0.92, respectively. The activity decreases by <5% over 200 h test at 750°C with a carbon accumulation rate of only 0.54 mg C/(g cat ·h).

UV-curing-assisted direct ink writing (DIW) is an established additive manufacturing technique for composite solid propellants, facilitating the development aerospace propulsion systems. However, direct application to aluminum (Al)-containing propellant slurries leads to limited curing depth, attributed to the high UV absorbance of aluminum powder. To address this limitation, we propose a novel surface modification strategy in which aluminum powders are coated with polytetrafluoroethylene (PTFE), yielding PTFE@Al composite powders with a core-shell structure. UV absorbance measurements show that PTFE coatings reduce the absorbance of aluminum powder by approximately 63%. Scanning electron microscopy (SEM) confirmed the uniformity and integrity of the PTFE coatings. Thermogravimetric (TG) and differential scanning calorimetry (DSC) analyses indicate that PTFE coating significantly enhances the energy release of aluminum powder, achieving an exothermic heat output of 2.19 kJ·g -1 below 1400 °C-approximately three times that of uncoated aluminum. Furthermore, curing tests on formulations containing PTFE@Al powders demonstrated an approximate 15% increase in curing depth. These results demonstrate that PTFE@Al composite powders not only overcome the limitations of aluminum’s UV absorption but also significantly enhance photocuring efficiency and energetic output. This work presents an innovative material design strategy and a practical route for additive manufacturing of high-performance solid propellant grains.

This study successfully synthesizes a highly efficient and stable electrolyte material for low-to-medium temperature solid oxide fuel cells, LaSrBaCeFeO x . It addresses issues of material degradation, high costs, and slow startup commonly associated with conventional electrolytes at elevated temperatures. Research reveals that the material forms a thermodynamically stable biphasic structure, composed of perovskite and Ruddlesden-Popper phases at the nanoscale. This unique microstructure results from the interplay between high configurational entropy and strong chemical driving forces within the multi-component system. X-ray diffraction and high-resolution transmission electron microscopy confirm the uniform coexistence of both phases. The material demonstrates remarkable electrochemical performance at moderate to low temperatures. A single cell with this electrolyte achieves a peak power density of 873 mW cm −2 at 550 °C, with a low ohmic resistance of 0.14 Ω cm 2 . Proton conduction experiments further confirm its potential as a mixed conductor. The high-entropy biphasic structure enhances performance through synergistic effects, as evidenced by X-ray photoelectron spectroscopy, electron paramagnetic resonance, and thermogravimetric analysis, which indicate abundant oxygen vacancies and high oxygen exchange activity. The system’s configuration entropy stabilizes the structure, optimizing oxygen vacancy formation and migration. This study provides a promising electrolyte material for next-generation SOFCs and demonstrates the potential of high-entropy design in multifunctional ion conductors, offering new solutions for sustainable clean energy technologies aligned with carbon neutrality goals.

A two-step synthesis strategy was employed to synthesize TiO 2 particles with distinct morphologies and crystallinities for electrorheological (ER) fluids. Amorphous TiO 2 (A-TiO 2 ) and non-calcined urchin-like mesoporous TiO 2 spheres (UMTS) were successfully synthesized via sol-gel and hydrothermal reactions, respectively. Subsequently, calcination further enhanced the crystallinity of the non-calcined UMTS. The TiO 2 particles suspended in silicone oil (10 % volume fraction) were evaluated for their ER performance under varying electric fields (0-3 kV/mm). The ER properties of three variants were characterized in terms of shear stress, shear viscosity, reversibility, and ER efficiency with respect to shear rate under different electric field strengths. As a result, a well-defined chain-like structure is confirmed through an optical microscope (OM). The morphological characteristics of these microstructures were examined using scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and Zeta potential, which showed spherical particles (480 nm in average diameter) with urchin-like morphology featuring radially oriented nanotips on their surface. Critically, Fourier transform infrared spectroscopy (FTIR) verified the successful surface modification, confirming the presence of functional groups (OH, Ti-O-Ti) essential for the electrorheological (ER) effect and Brunner Emmett Teller (BET) analysis confirmed the high surface area (up to 214 m 2 g −1 ) of the synthesized non calcined UMTS, which results to achieve an excellent electrorheological response. X-ray powder diffraction (XRD) analysis revealed the phase conversion from an amorphous to a crystalline anatase structure. Furthermore, the results indicate that heat treatment on crystalline structure significantly influences the ER characteristics, including dielectric loss factor and charge accumulation behavior. The results indicated that the non-calcined UMTS exhibits a higher shear stress, 1270 Pa at 3 kVmm −1 than A-TiO 2 and calcined UMTS. These findings reveal a complex interplay between microstructure and ER performance, offering valuable insights for optimizing ER fluids.

Silicon heterojunction (SHJ) solar cells employ a hydrogenated amorphous silicon (a-Si:H) layer to achieve highly efficient passivation of the crystalline silicon (c-Si) surface, thereby enabling high open-circuit voltage (V OC ). However, during long-term operation, the intrinsic amorphous silicon (i-a-Si) passivation layer is susceptible to degradation under ultraviolet (UV) irradiation, resulting in performance decline. To mitigate this issue, the present study develops a ZnO-based anti-reflective (AR) UV cutoff multilayer film. A zinc oxide (ZnO) precursor is prepared via a simple sol-gel method, and subsequently subjected to high-temperature curing to form a uniform coating on the glass surface. An additional AR layer is then deposited using the same process to further enhance transmittance and weather resistance. Experimental results demonstrate that the fabricated ZnO-AR film exhibits significantly reduced transmittance in the 250 nm - 380 nm UV band while maintaining an average transmittance of 94.52% in the 380 nm - 1100 nm visible-to-near-infrared range. The film also shows excellent environmental stability, with performance retained after high-temperature, high-humidity, and UV aging tests. SHJ cells coated with this film achieve a short-circuit current density of 37.27 mA cm −2 , representing a 5.16% improvement compared to cells with uncoated glass. Given its straightforward fabrication process and robust weather resistance, this approach offers effective technical support for the practical outdoor deployment of SHJ solar cells.
