Abstract ：
The advancement of hydrogel-based epidermal sensors that integrate multifunctionality, high transparency, rapid processing, and heightened sensitivity is of significant interest. Herein, we present an efficient approach for the fabrication of flexible dual-mode epidermal sensors through the ultraviolet (UV)-curing 3-D printing of polyacrylamide (PAM)-based ionic hydrogels. The hydro-gel precursor incorporates sodium dodecyl sulfate (SDS) monomers to augment the water dispersibility of the 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO) photoinitiator, thereby substantially increasing the photocuring efficiency of the ionic hydrogel. As a result, the distinctive surface microstructures of PAM-based ionic hydrogels can be engineered for sensors with varying sensing modalities to improve detection performance. The piezoelectric tactile sensor, incorporating a concentric ring microstructure, demonstrates a sensitivity coefficient of 1.39 mV kPa(-1). Conversely, the resistive strain sensor, characterized by a high-density reticular hollow structure, exhibits the highest gauge factor of 24.87. Furthermore, each sensor modality demonstrates excellent temporal response and stability, confirming its applicability in motion monitoring and Morse code transmission.

Abstract ：
The development of diverse microstructures has substantially contributed to recent progress in high-performance electromagnetic wave (EMW) absorption materials, providing a versatile platform for the modulation of absorption properties. Exploring multidimensional microstructures and developing tailored and gentle strategies for their precise optimization can substantially address the current challenges posed by relatively unclear underlying mechanisms. Here, a series of 2D/1D heterogeneous NiO@PPy composites featuring hollow hierarchical microstructures are successfully synthesized using a straightforward strategy combining sacrificial templating with chemical oxidative polymerization. This strategy offers a facile and effective approach to fine-tune the microstructure by adjusting the thickness of the polypyrrole (PPy) coating. This enables the continuous optimization of the dielectric properties and specific microstructures to maximize EMW absorption. Remarkably, the optimized 2D/1D hierarchical hollow NiO@PPy composite demonstrates an ultrathin thickness of 2.3 mm, a wide effective absorption band spanning 5.89 GHz, and a strong absorption intensity of -71.65 dB at a minimal loading of only 10 wt.%. The proposed mild and controllable preparation strategy not only provides insights for further tailoring the optimal dielectric properties of specific structures to enhance the absorption capacity, but also enriches the exploration of the underlying absorption mechanisms from the perspective of microstructure regulation.

Abstract ：
Herein, we present the synthesis and characterization of a novel phosphorus-containing epoxy co-curing agent, ANVD, fabricated via a one-pot method utilizing vanillin, 1,5-diaminonaphthalene, and DOPO as raw materials. Structural analysis conducted through FTIR and NMR spectroscopy confirmed the composition of ANVD. Differential scanning calorimetry (DSC) results indicated ANVD has significant contribution to the curing crosslinking of DGEBA, resulting in a slightly decreased Tg value for EP/ANVD compared to EP/DOPO, albeit still notably higher. Thermogravimetric analysis (TGA) revealed a reduction in the T5% and Tmax values of EP/ANVD, yet ANVD's superior char-forming ability increased char residue mass at elevated temperatures. Combustion tests showcased the outstanding flame retardancy of EP/ANVD, with EP/ANVD-5 exhibiting a limiting oxygen index (LOI) value of 33.2 % and achieving a V-0 rating in the UL-94 test. Furthermore, EP/ANVD-5 displayed a notable decrease of 38.6 % and 32.1 % in pHRR and av-HRR, respectively, compared to pure EP, surpassing EP/DOPO with equivalent phosphorus content. Analysis of decomposition products in both condensed and gas phases revealed ANVD's role in forming dense and continuous expanded char layers during combustion, releasing phosphorus radicals and non-combustible gases, thus exhibiting dual-phase flame retardant effects. Additionally, EP/ANVD-3 exhibited enhanced mechanical properties, with tensile strength and modulus increasing from 68.5 MPa and 0.75 GPa to 76.5 MPa and 0.86 GPa, respectively, compared to pure EP. Overall, the introduction of the bio-based flame retardant ANVD presents promising opportunities for the utilization of bio-based materials in flame retardancy applications.

Abstract ：
The development of modern electronic devices necessitates the creation of materials that exhibit both excellent thermal conductivity and high electromagnetic wave absorption performance. This study focuses on the synthesis of a dual-functional composite material, Co-C@PDA@BN, by incorporating boron nitride (BN) onto a metal-organic framework (MOF)-derived Co-C core through the strong adhesion properties of polydopamine (PDA). The heterogeneous structural interface enhances interfacial polarization, thereby optimizing wave absorption. The thermal conductivity can be improved by adjusting the ratio of Co-C to BN. A composite with a Co-C to BN ratio of 1 : 5 shows a minimum reflection loss of -55.3 dB at 5 wt% and a thermal conductivity of 0.396 W m-1 K-1, while a ratio of 1 : 20 achieves a thermal conductivity value of 0.464 W m-1 K-1 with a minimum reflection loss of -44.9 dB, demonstrating the facile tunability of these two properties. This work provides a promising pathway via heterostructure design to balance thermal conductivity and wave absorption characteristics, which may offer guidance for advancing electronic device technology.

Abstract ：
The adsorption and separation behaviors of CF₄/N₂ in Li-, Na-, and K-doped covalent organic frameworks (COFs) were investigated using GCMC simulations and DFT calculations. The results demonstrated that Li, Na, and K atoms could be stably incorporated into the COF structures, with binding energies ranging from −0.7358 to −1.3720 eV, ensuring the structural stability of the metal-doped COFs. Metal doping introduced additional adsorption sites, significantly enhancing the CF₄ adsorption performance. At 298 K and 100 kPa, Li-doped COFs exhibited the highest CF₄ adsorption capacity, reaching 5.55 mol/kg, a substantial improvement compared to the pristine COF-3PD (3.63 mol/kg). Furthermore, COF-3PD-Li achieved the highest CF₄/N₂ selectivity, with a selectivity ratio of 13.26, representing a 32% enhancement over the pristine COF-3PD. Interaction analysis showed that Li doping significantly enhanced the CF₄-framework interaction. These findings highlight the potential of Li-doped COFs as advanced materials for CF₄/N₂ separation. © 2025

Abstract ：
Conformal e-tattoos have recently received widespread attention because of their great potential for precise and immediate monitoring of physiological signals. However, expensive materials or complex fabrication processes are often required to obtain e-tattoos that meet the above application requirements. Here, we propose a facile strategy for the preparation of e-tattoos via screen printing while achieving versatile parameters collection capabilities. The screen printing inks can be obtained only by mixing and stirring carboxylated MWCNTs water slurry, elastomer transparent glue, glycerin and commercial ink according to the needs of target signal detection. Furthermore, a layer of ultra-thin medical pressure-sensitive adhesive layer was subtly involved in the temperature and humidity sensitive e-tattoos, successfully avoiding the mutual interference between the physical signals and the electrophysiological signals. The continuous monitoring of sEMG signals, ECG signals, local humidity conditions, and skin temperature changes can be achieved by applying the multifunctional e-tattoo platform onto the human skin surface. This technology shows promise as a potential avenue for the advancement of electronic tattoo sensing in the future.

Abstract ：
The natural porosity architectures, polar functional groups, low density, and biocompatibility of biomass carbon materials make them highly promising for the development of lightweight electromagnetic microwave absorbers. Sugarcane bagasse served as the raw material for this investigation, and sugarcane bagasse-derived carbon/FexOy was prepared using the in-situ growth method and temperature field-directed casting. By adjusting the content of ferrite hollow spheres, magnetic conduction losses and heterogeneous interfacial polarization losses are improved. Controlling the electrical conductivity losses and multiple scattering structures of biomass-derived carbon at different annealing temperatures, impedance matching is achieved through the synergistic operation of various loss mechanisms. BDC@C-1.2-750 exhibited a minimum reflection loss (RLmin) of-46.6 dB at a filler content of only 5 wt% and a thickness of 1.9 mm and obtained a maximum effective absorption bandwidth (EABmax) of 5.52 GHz at the same thickness. The ice template directional casting formed an orderly thermal conduction path, providing channels for phonon and electron transport, which is beneficial for the efficient heat dissipation of the microwave absorber. This finding thus offers a promising technique for creating ultra-lightweight microwave absorbers that facilitate heat dissipation.

Abstract ：
As one of the most potent greenhouse gases, SF6 has a significant economic and environmental impact on the purification and recovery of exhaust gases from the semiconductor industry. The adsorption and separation performance of SF6 on a two-dimensional covalent organic framework TAT-COFs-1-AB with different functional groups (-SO3H, -Et, -NH2, -OMe, -OH, -H) was investigated by using grand canonical Monte Carlo (GCMC) simulations and density functional theory (DFT) calculations. The results show that the adsorption at low pressure depends on the interactions between the SF6 and COF frameworks, while at high pressure it is mainly affected by the porosity. The highest adsorption capacity of 8.44 mmol/g (298 K, 100 kPa) is exhibited by TAT-COF-1-AB-H, which has the highest porosity. Chemical functionalization was found to be effective in enhancing the SF6/N-2 selectivity. Among all the functionalized COFs, TAT-COF-1-AB-NH2, with the highest specific surface area and strong heat of adsorption, showed the highest selectivity. The simulation of self-diffusion also shows consistent results with the GCMC simulation. The findings highlight that the adsorption capacity is influenced by substituent and porosity, with SF6 showing a consistent preference for adsorption at hollow sites, as evidenced by binding energy and charge transfer analyses.

Abstract ：
Two-dimensional Ti3C2Tx (MXene) nanosheets with excellent electrical conductivity, a vast range of func-tional groups, and abundant surface defects reveal tremendous potential for electromagnetic wave (EMW) absorption. Nonetheless, the excessive conductivity of pure MXene may result in mismatches of electro-magnetic parameters and an inability to meet impedance matching requirements. Here, a facile self-as-sembly strategy was used to assemble MXene with ZnFe2O4 (ZFO) through polydopamine (PDA) to form ZFO@PDA@MXene (ZFPM) core/ shell/ shell composites, which solved this problem. By strong hydrogen bonding, MXene was successfully affixed to the interface of ZFO@PDA, forming a core/shell/shell structure, in which ZFO is the core, and PDA and MXene are the shells. Furthermore, the influence of MXene content on the EMW absorption performance for ZFPM composites was also investigated. Remarkably, the ZFPM composites containing 20 wt. % MXene exhibit strong EMW absorption, achieving an optimum reflection loss of -53.0 dB (99.9995 % absorption of EMWs) at a matched thickness of only 1.5 mm. The excellent EMW absorption performance is mainly attributed to the synergistic effect related to the core/shell/shell structure of the ZFPM composites and the magnetic dielectric loss. These results demonstrate that ZFPM composites are attractive candidates for EMW absorption applications and offer new ideas for the design of magnetic MXene-based absorbers.(c) 2023 Elsevier B.V.

Abstract ：
Polyimide (PI) is widely used in the communication field benefited from its low dielectric properties and good electrical insulating properties, however, its low thermal conductivity simultaneously limits its application in electronic packaging. Delayed heat dissipation can exacerbate the thermal stress generated by device operation to damage electronic structures, thereby affecting work efficiency. As a result, it is necessary to improve the thermal conductivity of polyimide and maintain excellent dielectric performance. Here, we demonstrate the polyimide (BPDA-ODA) composites with ordered structure are prepared by filling commercial polyimides with aramid nanofibers connection nitrides greatly improve thermal conductivity and maintain the low dielectric loss. When the filling amount of SBN@CN is 30 wt%, the thermal conductivity increases to 1.162 W/mK, which is 8 times higher than that of pure PI (0.0147 W/mK). Moreover, thermal stability and mechanical properties are maintained, realizing that the dielectric constant is about 3.81 and the dielectric loss is as low as 0.0034 at 100 MHz, which endows a new insight for the application of polyimide in electronic packaging.
