With the wide application of soft tissue fillers, implant material-induced inflammatory reactions have become a key factor affecting the therapeutic efficacy. This study developed an injectable filler with enhanced anti-inflammatory and antioxidant effects by adsorbing glycyl-L-histidyl-L-lysine copper complex (GHK-Cu) onto hydroxyapatite microspheres (HAPs), marking the first combination of HAPs and GHK-Cu to address inflammation caused by soft tissue fillers. GHK-Cu was successfully loaded onto HAPs by electrostatic adsorption. HAPs were then mixed with carboxymethyl cellulose (CMC), glycerol (GLY), and water to form GHK-Cu@CMHA gel. The study focus on the effective combination of HAPs as a carrier for sustained GHK-Cu delivery and the anti-inflammatory properties of GHK-Cu. GHK-Cu@CMHA exhibits sustained release properties for 7 days, which ensures prolonged therapeutic effects, minimizes peptide waste and reduces injection frequency, with good flowability and injectability. In the model of LPS-induced inflammation model in vivo and in vitro, GHK-Cu@CMHA gel reduced levels of inflammatory factors and Reactive oxygen species (ROS) levels decreased, while superoxide dismutase (SOD) activity was enhanced. In this process, H&E staining and Masson staining revealed significant collagen deposition. These findings further confirm that GHK-Cu@CMHA is a novel injectable soft tissue filler with good anti-inflammatory and antioxidant properties, which holds well potential for inflammation inhibition. © 2025, The Authors.

Self-assembly of functional units represents an important synthetic approach in the rational design of nanomaterials with precisely-controlled chemical compositions, nanostructures and desired properties, and hence finds vast applications in areas including but not limited to biomedical engineering, separation, energy storage and conversion. The functional units which can be used in self-assembly range from small molecules, metal ions, clusters, nanoparticles to large polymeric molecules. Finely tuning the functional groups of assembly units and the bonding/interactions between the units can generate versatile materials with unique structures and properties, thus leading to the desired performances for various applications. Notably, under varied external conditions, the chemical bonding, interactions between the assembly units and the structures can also be varied, which further endows these materials with responsive properties for applications in multidisciplinary areas. In recent years, I have studied a series of self-assembled nanostructured materials which are based on metal-organic coordinative compounds constructed between metal ions and organic ligands. Nanostructuring of these materials endow them with greatly enhanced properties in electrochemical energy storage. Moreover, in combination with controlled pyrolysis and understanding of the structure-property relationship, the rational design and controlled synthesis of nanocarbon composite electrode materials towards high-performance electrochemical energy storage and conversion becomes feasible. In this talk, I will present some of our recent work on the rational design of self-assembled metal-organic nanostructures and their derived nanocarbon materials for electrochemical energy storage.

Lithium-sulfur batteries have the advantages of high theoretical energy density(2600 Wh kg-1), low-cost and environmental friendliness, which is one of the most promising secondary battery systems. However, the practical application of Li-S batteries has still been restricted by the low Coulombic efficiency and rapid capacity decay deriving from the low conductivity of sulfur cathode, large volume expansion（～80%） during discharging, and serious lithium corrosion/dendrite of anode, particularly, high dissolution of the discharge intermediate polysulfides（LiPSs） in electrolyte and shuttle effect between cathode and anode.

Multi-component high-entropy carbide ceramics have emerged as a promising class of materials due to their exceptional mechanical performance, thermal stability, and chemical corrosion resistance. In this study, we employed pyromellitic acid as the carbon source and developed a metal-organic-gel method to synthesize (TiZrNbTa)C high-entropy precursors. Through carbothermal reduction at relatively low temperature of 1500°C, homogeneous single-phase face-centered cubic solid solution were obtained successfully. Subsequently, the carbide ceramics were fabricated using SPS. Characterization results demonstrate that the synthesized powders exhibit quasi-spherical morphology with uniform particle size distribution and average diameter of 57 nm. The SPS-sintered (TiZrNbTa)C high-entropy ceramics demonstrate remarkable performance, achieving relative density as high as 99.8% with uniform microstructure and particle size of 0.44 ± 0.1 μm. The material exhibited outstanding mechanical performance, with Vickers hardness and fracture toughness reaching 21.82 ± 1.5 GPa and 4.565 ± 0.5 MPa·m 1/2 , respectively.

Hydrogels are promising candidates for flexible electronics but are often constrained by narrow pressure-sensing ranges and unstable ion migration. To overcome these limitations, we developed an ionic hydrogel sensor incorporating diode-inspired bipolar architectures (PSSNa/PDACl) and poly(vinylidene fluoride)/carbon directional microchannels (PCDMC). The optimized 5-PCNPC hydrogel exhibits a broad pressure-sensing range (2.3–100 kPa) with a sensitivity of 0.360 mV·kPa−1 (a 34.8 % enhancement) and a rectification ratio of 12.9, enabled by PCDMC-guided anisotropic ion transport and rapid stress dissipation (337 ms recovery). With excellent durability over 500 cycles and a power density of 1.17 mW·m−2, the hydrogel sensor demonstrates its potential in practical applications, including a 5 × 5 touchpad for spatial pressure mapping and real-time monitoring of respiration, swallowing, grasping and locomotion. This study underscores the potential of hydrogel-based sensors with wide-range operability for next-generation wearables and interactive systems. © 2025 Elsevier B.V.

One-dimensional nanomaterials can offer large surface area, facile strain relaxation upon cycling and efficient electron transport pathway to achieve high electrochemical performance. Hence, nanowires have attracted increasing interest in energy related fields. We designed the single nanowire electrochemical device for in situ probing the direct relationship between electrical transport, structure, and electrochemical properties of the single nanowire electrode to understand intrinsic reason of capacity fading. The results show that during the electrochemical reaction, conductivity of the nanowire electrode decreased, which limits the cycle life of the devices. We have developed a facile and high-yield strategy for the oriented formation of CNTs from metal-organic frameworks（MOFs）. The appropriate graphitic N doping and the confined metal nanoparticles in CNTs both increase the densities of states near the Fermi level and reduce the work function, hence efficiently enhancing its oxygen reduction activity. In addition, we demonstrated the critical role of structural HO. The results suggest that the HO-solvated Zn possesses largely reduced effective charge and thus reduced electrostatic interactions with the VO framework, effectively promoting its diffusion. We also identified the exciting electrochemical properties（including high electric conductivity, small volume change and self-preserving effect） and superior sodium storage performance of alkaline earth metal vanadates through preparing CaVO nanowires. Furthermore, a novel assembled nanoarchitecture was also presented, which consists of VO nanoparticles embedded in amorphous carbon nanotubes that are then coassembled within a reduced graphene oxide network. The naturally integrated advantages of each subunit exhibit highly stable and ultrafast sodium-ion storage. Our work presented here can inspire new thought in constructing novel one-dimensional structures and accelerate the development of energy storage applica

Increasing the energy density, power density as well as widening the operation voltage are essential to electrochemical capacitors to meet the practical energy demands. Herein, a novel flexible quasi-solid-state dual-ion asymmetric supercapacitor(ASC) with Ni(OH)2 and Nb2O5 nanosheets directly grown on stainless steel mesh is developed. In the dual-ion ASC, Nb2O5 negative and Ni(OH)2 positive electrodes react with Li+ and OH- respectively in alkaline gel electrolyte to store energy, which is quite different from conventional alkali metal ion SCs and alkaline SCs. The as-assembled flexible device has an extended working voltage of 1.7 V and delivers a capacity of 5.37 mAh cm-2, a maximum energy density and power density of 0.52 mWh cm-3 and 170 mW cm-3 , respectively. The device maintains around 60% capacity retention after long cycling up to 1000 cycles. Moreover, our device can light up a LED light efficiently upon fast charging. The proposed quasi-solid-state dual-ion ASC has potential applications in future portable electronics and flexible energy storage devices.

Journal of materials Science: materials in Electronics 2025年第16期36卷

作者： Wu, Zhang-Wei Wang, Yu-Qin Li, Qiang-Zhi Zhou, Jing Zhao, Min-Hao Pang, Zi-Yu Huang, Guan-Long Shen, Jie Chen, Wen Hubei Longzhong Laboratory Wuhan University of Technology Xiangyang Demonstration Zone Xiangyang441000 China State Key Laboratory of Advanced Technology for Materials Synthesis and Processing School of Materials Science and Engineering Wuhan University of Technology Wuhan430070 China Sanya Science and Education Innovation Park Wuhan University of Technology Sanya572024 China Guangdong Provincial Key Laboratory of Industrial Intelligent Inspection Technology Foshan University Foshan528225 China Guangdong-Hong Kong-Macao Joint Laboratory for Millimeter-Wave and Terahertz and Faculty of Science and Technology University of Macau SAR China

Reducing the dielectric constant (Εr) of inorganic dielectrics is both a requirement and a challenge for the development of high-frequency and high-speed electronics. Although introducing the air phase (Εr ≈ 1) effectively lowers Εr, conventional pore-forming fabrication methods that introduce open pores will reduce the mechanical strength and increase the interfacial polarization loss. This study introduces a prefabricated template method using hollow microspheres to prepare closed-pore porous ceramics. Through controlled heat treatment, this approach enhances interfacial bonding to improve mechanical strength while preserving closed-pore integrity. The developed materials exhibit high flexural strength (9.9 MPa) and better dielectric properties (dielectric constant 1.86, dielectric loss 0.0015 at 30 GHz), making them ideal for high-frequency and high-speed applications. Superior performance (S11 = − 62.62 dB, gain = 7.49 dBi at 21–24 GHz) were demonstrated by an antenna fabricated on this dielectric substrate, confirming its suitability for high-frequency signal transmission. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.
