Lithium (Li) metal anodes (LMAs) that employ three-dimensional lithiophilic frameworks are among the most promising options for constructing high-energy-density rechargeable batteries. Herein, hollow ZnS nanosheets with the coating of N-doped carbon are modified on the surface of carbon cloth (NCHZS@CC) to serve as the host material for Li metal. It is revealed that the high surface area of NCHZS@CC can significantly reduce local current density and mitigate volume change during cycling. More importantly, the lithiated product of ZnS, confined within the carbon cage, facilitates the uniform deposition of Li metal on carbon fibers and promotes the formation of a stable solid electrolyte interphase enriched with Li 2 S, thereby improving long-term performance as the cycling progresses. Consequently, the LMAs based on NCHZS@CC demonstrate an impressive cycle life beyond 560 h with an ultralow overpotential of 38 mV at a current density of 5 mA cm −2 with a capacity of 1 mAh cm −2 in the symmetric cell. In addition, when matched with a high mass loading cathode of LiFePO 4 (11.5 mg cm −2 ), the assembled full cell displays outstanding performance, achieving 900 cycles at a rate of 2C.

In this paper, a molecular imprinted metal-organic framework was prepared by a simple one-pot method using lanthanide terbium ions as the metal source, 2-aminoterephthalic acid as the organic ligand, and 4-nitrophenol as the template molecule at 120 °C. The materials of imprinted and non-imprinted metal-organic framework were characterized and analyzed by Scanning Electron Microscope, X-ray photoelectron spectroscopy, X-ray Diffraction, Brunauer-Emmett-Teller Specific Surface Area Analysis and fluorescence methods, etc., respectively. The fluorescence of the imprinted metal-organic framework was quenched by 4-nitrophenol in water, and there was a linear correlation between the fluorescence quenching efficiency of molecular imprinted metal-organic framework and the logarithm of 4-nitrophenol concentration in the range of 10–500 µmol L − 1 . The limit of detection was 3.3 µmol L − 1 (3σ) and the limit of quantitation was 11.0 µmol L − 1 (10σ). The molecular imprinted metal-organic framework was used for the determination of 4-nitrophenol concentration in water samples with the recoveries of 93.5-102.9% and the relative standard deviations less than 3.63%. The molecular imprinted metal-organic framework has the advantages of easy preparation, high stability, good sensitivity and selectivity, which has potential application for the detection of 4-nitrophenol in the environment samples.

The ability to manipulate acoustic fields in a real-time and high-resolution manner can open up many opportunities for engineering and medical applications. Realising this would demand an acoustic metamaterial that can modulate acoustic waves in a programmable manner. We achieve this goal using a crosslinked semi-crystalline polymer for which any arbitrary modulus pattern can be repeatedly encoded/erased in roughly 13 minutes. Critically and surprisingly, the material allows acoustic wave transmission with low attenuation, despite its multiphase nature. With the modulus pattern and acoustic transparency, reconfigurable phase holograms can be created. Combined with an electrically switchable and compact partitioned piezo-electric transducer, the device allows generating acoustic fields with a high modulation resolution of 10000 pixels/cm 2 at an ultra-fast switching rate of 50000 fps for specified dynamic holography, far exceeding existing approaches. By programming the semi-crystalline polymer with different phase holograms, together with the selective excitation of partitioned piezo-electric transducer for incident wavefront modulation, it allows an unprecedented opportunity to create acoustic movies and remote thermal writing, with strong implications for many other future technological possibilities.

A magnetic double-layer metal-organic framework composite (Fe 3 O 4 @ZIF-8@ZIF-67) was successfully synthesized through a facile layer-by-layer self-assembly method at room temperature and thoroughly characterized using various techniques. The composite Fe 3 O 4 @ZIF-8@ZIF-67 was explored as an adsorbent for the removal of two harmful organic pollutants, Congo red (CR) and tetracycline hydrochloride (TC). Some essential parameters, including initial concentration, adsorbent dose, contact time, pH, and temperature, were systematically optimized. Under optimal conditions, Fe 3 O 4 @ZIF-8@ZIF-67 demonstrated the maximum adsorption capacities of 276.77 mg/g for CR and and 356.12 mg/g for TC, respectively. The double-layer structure endowed Fe 3 O 4 @ZIF-8@ZIF-67 high adsorption efficiency for CR (99.44%) than the pristine Fe 3 O 4 @ZIF-8 (73.26%). Adsorption kinetics and isotherms studies revealed that the adsorption process followed pseudo-second-order kinetics and Langmuir model, indicating a monolayer chemisorption-dominated mechanism. Furthermore, the spent Fe 3 O 4 @ZIF-8@ZIF-67 was regenerated through a Fenton-like oxidative degradation reaction, maintaining a removal efficiency above 70% after three consecutive cycles. With its facile synthesis, cost-effectiveness, mild operating conditions, and high selectivity for anionic dyes, Fe 3 O 4 @ZIF-8@ZIF-67 emerges as a highly promising material for advanced wastewater treatment applications.

Aqueous zinc-ion batteries (AZIBs) have promising for large-scale energy storage due to their low cost and high safety. However, the slow migration rate and strong electrostatic repulsion of Zn 2+ impose stringent requirements on the selection of cathode material. Therefore, the development of suitable cathode materials is crucial for the further advancement of AZIBs, playing a vital role in reducing costs and enhancing electrochemical performance. Vanadium pentoxide (V 2 O 5 ) exhibits potential for energy storage due to its relatively high theoretical specific capacity. This study proposes an in-situ synthesis strategy to directly grow V 2 O 5 nanostructures onto a graphite felt (GF) substrate, constructing a self-supported, binder-free V 2 O 5 @GF composite cathode. The high electrical conductivity of GF serves as a three-dimensional conductive network, effectively promoting electron transfer kinetics between the active material and the electrolyte, and enhancing the structural integrity of the cathode material, thus significantly improving electrochemical cycling stability. As a cathode material for AZIBs, V 2 O 5 @GF demonstrates impressive discharge specific capacity (507 mAh/g at 0.2 A/g), along with outstanding rate capability (165 mAh/g at 5 A/g), and a long-cycling life (86.5% capacity retention after 2000 cycles at 4 A/g). This study provides a new approach and direction for the high-specific-capacity development of AZIBs.

Advanced sensation and actuation abilities of various living organisms in nature have inspired researchers to design bioinspired somatosensory soft actuators. However, the majority of conventional soft actuators primarily possess actuation capabilities while lacking real-time sensing signal feedback. Here, a promising strategy is reported to develop highly stretchable and conductive hydrogels for bioinspired somatosensory soft actuators, which integrate actuation and strain-sensing functions into a single materials system. The conductive hydrogels are designed and synthesized by in situ copolymerization of polydiallyldimethylammonium chloride functionalized MXene (P-MXene) nanosheets and poly N-isopropylacrylamide-co-acrylic acid (PNIPAm/PAA) hydrogels. The resulting hydrogels exhibit the dual-crosslinked conductive network and porous microstructure, enabling the seamless combination of excellent strain sensitivity, high conductivity, rapid responsiveness, high stability, and extensive stretchability. Interestingly, the anisotropic network structure, formed by electrically driven nanosheet gradient distribution of P-MXene nanosheets, endows the hydrogel with shape-programmable deformation, light-driven remote control, and self-sensing capability. As a proof-of-concept application, a soft gripper based on self-sensing hydrogel actuators has been developed, which can not only grasps, lifts, and releases objects but also detects its movement states by monitoring resistance variations. The proposed somatosensory soft actuator can offer promising perspectives for the advancement of smart soft robotics and other artificial intelligent devices.

Current approaches for bone repair predominantly target localized delivery of growth factors that are aimed at the coupling of angiogenesis and osteogenesis. However, delayed revascularization and regeneration of critical-sized bone defects are still challenging. In this study, we engineer an ossification center-like organoid (OCO) that consist of an inner-core bone morphogenetic and neurotrophic spheroid generated via MSCs-loaded 3D printing, alongside the interstitially distributed outer-shell proangiogenic neurotrophic phase. Our results demonstrate that collective implantation of OCOs achieves rapid bone bridging with successive OC-like bone ossicles formation across the bone defect in a “divide-and-conquer” way. Single-cell RNA sequencing analysis unveils a developmentally mimicking stem cell community that dominated with Krt8 + skeletal stem cells (SSCs) is uniquely recruited by the pro-regenerative in-situ organoid fusion and maturation. Particularly noteworthy is the specific expansion of Krt8 + SSCs concomitant with the simultaneous reduction of Has1 + migratory fibroblasts (MFs) post-OCO implantation. Furthermore, cross-species comparisons employing machine learning reveal high resemblance of the relative Krt8 + SSCs/Has1 + MFs composition in bone regeneration with that in public data from developmental bone tissues. Our findings advocate an approach akin to “divide-and-conquer” utilizing engineered OC-like organoids for prompt regeneration of large-sized bone defects.

Flash sintering has revolutionized the field of advanced ceramic preparation with the low heating temperature and extremely short sintering time. The difference of doped ions radius can influence the defect structure and resistivity of the sample through lattice distortion, subsequently altering the parameters and dielectric properties of flash sintering samples. By flash sintering technology, co-doped TiO 2 ceramics with the acceptor ions (Mg 2+ , Ca 2+ , Sr 2+ , Ba 2+ ) and donor ions (Nb 5+ ) were successfully prepared at 1100 °C for 24 min. According to the blackbody radiation model, Mg 2+ and Nb 5+ co-doped TiO 2 ceramics exhibit the highest surface temperature at the moment of flash sintering, approximately 1852 °C. Additionally, the co-doped TiO 2 ceramics with Ba 2+ and Nb 5+ ions exhibit the strongest polarization effect, with a dielectric constant above 10 5 . The acceptor ions with larger ions increase oxygen vacancies by enhancing the stability of defect complexes. The excellent giant dielectric properties are attributed to the combined action of the electron-pinned defect dipole effect and the internal barrier layer capacitor effect.

Ideal laminar membrane reactors (LMR) necessitate the rational construction of 2D nanoconfined channels and regulation of microenvironment. The intrinsic structure-activity relationship of laminar membrane reactors essentially remains unclear. Herein, amorphous/crystalline HTiNbO 5-X nanosheets (NS) with abundant oxygen vacancy (V O ) are successfully prepared and stacked as 2D sub-nanoconfined membrane flow reactors with different interlayer spacings. When the interlayer spacing is decreased to 11.0 Å, the representative HTiNbO 5-X membrane exhibits impressive conversion of ≈ 100% within 26.6 s and turnover number of up to 306.42 for the esterification of benzyl alcohol at 23 °C. The combination of structural characterizations and theoretical calculations reveals that the synergistic effect of V O and sub-nanoscale confinement greatly promotes the adsorption and orbital symmetry matching of reactants, and reduces the overall energy barrier. Furthermore, the HTiNbO 5-X LMR is accessible for other alcohol derivatives, indicating the efficient and green synthesis of acetate ester flavours under mild conditions. This work demonstrates the promising potential of the metal oxide nanosheets to create inorganic laminar membrane reactors for continuous organic synthesis.

Understanding the fundamental properties of actinide-based materials is pivotal in unlocking new solutions for challenges in nuclear waste management. In this work, we showcase a novel thorium cluster ( Th-npc ) that exhibits an extremely rare Th–N bond capping the square antiprismatic Th 4+ metal center. Remarkably, Th-npc exhibits both photochromic and radiochromic behaviors under UV and X-ray radiation, respectively, allowing for distinct, measurable colorimetric shifts that facilitate a red-green-blue (RGB) radiation dosimetry method. The integration of Th-npc with a custom-built optoelectronic device enables on-site radiation dosimetry, offering the advantages of simple operation and rapid data acquisition. Additionally, this work pioneers the application of actinide materials in photothermal conversion, opening new avenues for the strategic utilization of thorium-based compounds.

Living cationic polymerization of 4-acetoxystyrene (STO) was conducted in CH 2 Cl 2 at −15 °C using a dicumyl chloride (DCC)/SnCl 4 / n -Bu 4 NBr initiating system. Impurity moisture initiation was inhibited by adding proton trap 2,6-di-tert-butylpyridine (DTBP), and the controlled initiation of DCC was confirmed by 1 H nuclear magnetic resonance ( 1 H-NMR) spectroscopy and matrix-assisted laser desorption ionization time-of-flight mass (MALDI-TOF-MS) spectrometry. The polymerization kinetics were analyzed to for optimizing the polymerization rate. Allyl-telechelic PSTOs (allyl-PSTO-allyl) with molecular weight ( M n ) range of 3540–7800 g/mol and narrow molecular weight dispersity ( M w / M n ) about 1.25 were prepared through nucleophilic substitution with allyltrimethylsilane (ATMS) at approximately 40% monomer conversion. The experimental results indicate that the substitution efficiency of ATMS increased with higher ATMS concentration, temperature, and extended reaction time. Nearly unity ally-functionality for allyl-PSTO-allyl was achieved by adding sufficient SnCl 4 prior to the substitution.

High levels of nitrates and nitrites not only threaten aquatic ecosystems and drinking water safety but also impair the biodegradation efficiency of industrial wastewater. In this study, micro-nano-MoS 2 -1013 (0.04 g/L) enhanced denitrification by 56.9% and 29.6% in steel pickling and meat processing wastewaters, respectively, and improved chemical oxygen demand (COD) removal by 136.7% in refinery cooling wastewater under continuous-flow conditions using a 3.5 L upflow anaerobic sludge blanket (UASB) reactor. The catalytic effect of micro-nano-MoS 2 on denitrification was achieved by stimulating an increase in the abundance of denitrification genes and the transcript levels of narL (93.82 times), narG (16.34 times), and nirK (12.27 times) within the bacterial cells, which led to an increase in the expression levels of denitrifying enzymes. These findings have significant implications for the design and optimization of biodegradation processes and bio-denitrification systems, particularly for the treatment of high-concentration nitrate wastewater.
