Tactile sensory organs for three-dimensional (3D) force perception are essential for most living organisms and enable them to perform complex and sophisticated tasks to survive and evolve. Magnetic-based tactile sensors have been developed rapidly in recent years due to the exploitability of 3D force decoupling. Here, a method of magnet splicing is introduced, which can be applied to a magnetic tactile sensor to realize 3D self-decoupling of magnets’ displacements. This method enables the magnets to produce a completely consistent magnetic field distribution as the ideal magnetization model within a certain working range, eliminating the compensation and correction of the 3D magnetic flux density signal. This method carves out a new way for the practical application of 3D decoupling theory, showcasing the great potential in the fields of magnetic sensors and magnetic actuators.

Metal-organic frameworks (MOFs) are a kind of functional porous materials with the potential applications in gas adsorption and separation, catalysis, energy storage, sensor, and electrical conductivity . However, the insulating nature of the mostly MOFs limits their application in the electronic field. A new three-dimensional (3D) metal-organic framework composed of Cu 2+ centres and polyacid linkers (TATAB 3− ) was synthesized by solvothermal method , which contains two types of Cu 24 cages. The crystal structure is cubic and each Cu is coordinated by five oxygen atoms which can be confirmed by the single crystal X-ray diffraction, infrared spectra and TGA analysis. The conductivity for this 3D MOF is increased by four orders of magnitude after doping with 7,7,8,8-tetracyanoquinodimethane (TCNQ) and realizes the transformation from an insulator to semiconductor.

Ni-ethylenediaminetetraacetic acid (Ni-EDTA) poses serious threats to the ecological environment and human health, due to its acute toxicity and low biodegradability. The decomplexation efficiency of Ni-EDTA through the conventional Fenton process has been constrained to pH; thus, other appropriate approaches are required to destroy the stable chelate structure at a neutral pH. In this study, the effect of operating parameters such as the pH, Fe2+concentration, particle electrode dosage, current density, and coexisting ions was studied. The results revealed that the 3D-EF system owned advantages for the removal of Ni-EDTA in the broadening of the pH application window. The Ni-EDTA removal efficiency in the 3D-EF system reached 84.89% after 120 min at a pH of 7. In addition, the presence of coexisting ions slightly affected the decomplexation efficiency of Ni-EDTA.Keywords:Ni-EDTA;three-dimensional electro-Fenton;neutral pH;decomplexation

Three-dimensional (3D) poly(vinylidene fluoride) (PVDF)-based piezoelectric energy harvesters (PEHs) offer exceptional electromechanical conversion capabilities due to their flexible structures and customizable designs. However, how to design and construct such structures with enhanced strain for a higher piezoelectric output remains a complex challenge. This study presents a novel approach by combining the versatility of 3D printing with solvent exchange to create a unique 3D porous bamboo-structured PVDF/MXene PEH, allowing for a tailored hollow structure by adjusting the temperature and solvent concentration. This flexible design and construction of the macro- and micro-3D structures enables a synergistic amplification of stress–strain, hence a significant enhancement of the overall electromechanical conversion efficiency of the PEH. Additionally, the incorporation of MXene, with its abundant functional groups, achieves a high β-crystal content (92.6%) in the PVDF-based PEH. This coupling effect contributes to a piezoelectric output of 47 V and maximum sensitivity of 0.727 V/kPa, surpassing most PVDF-based sensors reported to date. Notably, the 3D PEH demonstrates its potential as a self-powered pressure sensor for monitoring human motions across varying amplitudes. This work unveils a universal strategy for harnessing 3D PEHs with high electromechanical conversion efficiency, paving the way for various applications in the fields of smart sensing and energy harvesting.

Two new boroantimonates, namely, KSbB2O6 and BaSb2B4O12, have been successfully synthesized through high-temperature solid state reactions. Their structures feature two types of novel anionic 3D frameworks composed of 1D chains of corner-sharing SbO6 octahedra that are interconnected by B2O5 groups. The 1D chains of corner-sharing SbO6 octahedra in polar KSbB2O6 (space group Cc) are extended along the c-axis, whereas those in the centrosymmetric BaSb2B4O12 (space group C2/c) are propagated along the [101] direction. The K+ ions are located at the 1D tunnels of the anionic frameworks along both b- and c-axis, whereas Ba2+ ions are located at the 1D tunnels of the anionic frameworks along both the a- and c-axis. KSbB2O6 is a polar material that displays weak SHG response, whereas BaSb2B4O12 is centrosymmetric and not SHG active. Studies on their optical properties, thermal stability, and band structure calculations based on DFT methods have been also performed.

A two-dimensional MXene (Ta4C3) was innovatively used herein to modulate the space group and electronic properties of vanadium oxides, and the MXene/metal–organic framework (MOF) derivative VO2(B)@Ta4C3 with 3D network cross-linking was prepared, which was then employed as a cathode to improve the performance of aqueous zinc ion batteries (ZIBs). A novel method combining HCl/LiF and hydrothermal treatments was used to etch Ta4AlC3 to obtain a large amount of accordion-like Ta4C3, and the V-MOF was then hydrothermally grown on the surface of the stripped Ta4C3 MXene. During the annealing process of V-MOF@Ta4C3, the addition of Ta4C3 MXene liberates the V-MOF from agglomerative stacking, allowing it to show additional active sites. More significantly, Ta4C3 prevents the V-MOF in the composite structure from converting into V2O5 of space group Pmmn but into VO2(B) of space group C2/m after annealing. A considerable advantage of VO2(B) for Zn2+ intercalation is provided by the negligible structural transformation during the intercalation process and the special tunnel transport channels, which have an enormous area (0.82 nm2 along the b axis). According to first-principles calculations, there is a strong interfacial interaction between VO2(B) and Ta4C3, which deliver remarkable electrochemical activity and kinetic performances for the storage of Zn2+. Therefore, the ZIBs prepared with the VO2(B)@Ta4C3 cathode material exhibit an ultra-high capacity of 437 mA h·g–1 at 0.1 A·g–1 while showing good cycle performance and dynamic performance. This study will offer a fresh approach and a reference for creating metal oxide/MXene composite structures.

Four-dimensional (4D) printing relies on multimaterial printing, reinforcement patterns, or micro/nanofibrous additives as programmable tools to achieve desired shape reconfigurations. However, existing programming approaches still follow the so-called origami design principle to generate reconfigurable structures by self-folding stacked 2D materials, particularly at small scales. Here, we propose a programmable modular design that directly constructs 3D reconfigurable microstructures capable of sophisticated 3D-to-3D shape transformations by assembling 4D micro-building blocks. 4D direct laser writing is used to print two-photon polymerizable, stimuli-responsive hydrogels to construct building blocks at micrometer scales. Denavit-Hartenberg (DH) parameters, used to define robotic arm kinematics, are introduced as guidelines for how to assemble the micro-building blocks and plan the 3D motion of assembled chain blocks. Last, a 3D-printed microscaled transformer capable of changing its shape from a race car to a humanoid robot is devised and fabricated using the DH parameters to guide the motion of various assembled compartments.

Chemical doping of MXenes with heteroatoms is expected to be a promising strategy for enhancing their electrochemical performance. Nevertheless, the synergistic effects of chemical doping and 3D structure construction have rarely been investigated in depth. Aiming to avoid MXene nanosheet restacking and further enhance the electrochemical performance, herein, we reported a simple strategy combining nitrogen doping with a 3D structure construction on MXenes via a one-step hydrothermal method. The location and types of nitrogen doping can be adjusted by hydrothermal conditions. The obtained nitrogen-doped Ti3C2Tx aerogel had an ultra-high specific surface area of 200.8 m2 g−1 with high porosity. The open reticular walls can expose more nitrogen-enriched Ti3C2Tx edges to the electrolyte. Nitrogen dopants at the edges of Ti3C2Tx nanosheets produced more number of active sites and provided higher pseudocapacitance, and the presence of N-C4 increased the electron mobility of Ti3C2Tx, which reduced charge transfer resistance evidently. As a result, the nitrogen-doped Ti3C2Tx aerogel showed an excellent specific capacitance (531 F g−1 in H2SO4 electrolyte) with good cyclic stability (remaining 96% after 5000 cycles).

In this study, we have demonstrated coordination-driven self-assembly between Fe3O4 and graphene sheets under a hydrothermal condition for the simple in situ synthesis of a 3D Fe3O4–graphene hybrid architecture (Fe3O4/G). Fine hierarchical Fe3O4 spheres were homogeneously dispersed and embedded in an interconnected mesoporous framework of graphene sheets. It can be noted that the critical concentration of GO assembly decreased dramatically during the self-assembly of Fe3O4, indicating the coordination-driven self-assembly between Fe3O4 and GO. When evaluated as an anode material for LIBs, the Fe3O4/G hybrid framework demonstrates a high reversible capacity of 1164 mA h g−1 over 500 cycles at a current density of 500 mA g−1 and a remarkable rate capability. The superior electrochemical performance is attributed to a strong adhesion force and synergistic effect between Fe3O4 and graphene sheets as well as formation of a 3D interconnected hybrid framework, which offers enhanced kinetics towards electrochemical reactions with lithium ions and provides space for alleviating the huge volume expansion that occurs during charge–discharge cycles.

Tissue clearing combined with high-resolution confocal imaging is a cutting-edge approach for dissecting the three-dimensional (3D) architecture of tissues and deciphering cellular spatial interactions under physiological and pathological conditions. Deciphering the spatial interaction of leptin receptor-expressing (LepR + ) stromal cells with other compartments in the bone marrow is crucial for a deeper understanding of the stem cell niche and the skeletal tissue. In this study, we introduce an optimized protocol for the 3D analysis of skeletal tissues, enabling the visualization of hematopoietic and stromal cells, especially LepR + stromal cells, within optically cleared bone hemisections. Our method preserves the 3D tissue architecture and is extendable to other hematopoietic sites such as calvaria and vertebrae. The protocol entails tissue fixation, decalcification, and cryosectioning to reveal the marrow cavity. Completed within approximately 12 days, this process yields highly transparent tissues that maintain genetically encoded or antibody-stained fluorescent signals. The bone hemisections are compatible with diverse antibody labeling strategies. Confocal microscopy of these transparent samples allows for qualitative and quantitative image analysis using Aivia or Bitplane Imaris software, assessing a spectrum of parameters. With proper storage, the fluorescent signal in the stained and cleared bone hemisections remains intact for at least 2–3 months. This protocol is robust, straightforward to implement, and highly reproducible, offering a valuable tool for tissue architecture and cellular interaction studies.

The reasonable design of magnetic carbon-based composites is of great significance to improving the microwave absorption (MA) performance of the absorber. In this work, ultrafine FeNi3nanocrystals (5–7 nm) embedded in a 3D honeycomb-like carbon matrix (FeNi3@C) were synthesized via a facile strategy that included a drying and carbonization process. Because of the soft magnetic property of the FeNi3nanocrystals and their unique 3D honeycomb-like structure, the FeNi3@C composites exhibit excellent MA abilities. When the filler loading ratio of FeNi3@C/paraffin composites is only 30 wt%, the maximum reflection loss (RL) value is −40.6 dB at 10.04 GHz. Meanwhile, an ultra-wide absorption frequency bandwidth of 13.0 GHz (5.0–18.0 GHz over −10 dB) can be obtained in the thickness range of 2.0–4.5 mm, and this means that the absorber can consume 90% of the incident waves. It benefits from the dual loss components, multiple polarizations, and multiple reflections for improving MA performances of FeNi3@C composites. These observations suggest that the 3D honeycomb-like FeNi3@C composites have broad application prospects in exploring new MA materials that have a wide frequency bandwidth and strong absorption.Keywords:FeNi3@C composites;3D honeycomb-like carbon;microwave absorption

Holistic catalytic reactors with fractal structures have attracted growing attention in heterogeneous reactions because of their advantages of improved mass transfer and easy separation. Herein, a cost-efficient and straightforward design strategy that combined three-dimensional printing and electroless deposition was presented to construct dynamic, holistic stirred reactors with the fractal structure. The conversion factor α of the fractal impeller is 65.01 mmol m −2 h −1 with a large volume of reactant (80 ml), which is 1.7 times that of the normal impeller with the same loading of Ag catalysts. Experimental results and simulation analysis demonstrate that the fractal impeller significantly improves the catalytic performance by enhancing mass transfer and spatial dispersion in the reaction. Moreover, the holistic impeller could be reused 10 times without obvious loss of catalytic performance, and easily separated from the reaction system. The structural design of fractal reactors will open the way for high-efficiency dynamic heterogeneous catalytic reactors.
