Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

Summary: A novel multifunctional composite based on Inter-Woven Wire Fabric (IWWF) was manufactured and investigated. The composite showed improved electrical conductivity and interlaminar fracture toughness compared to conventional laminates.

Summary: Mesoscale simulations of woven composites are used to connect constituent material properties and their geometric arrangement to effective composite properties and performance. However, the as-manufactured materials often differ from the ideal, resulting in variations in composite properties. The study compares idealized analytical and as-manufactured woven composite materials and evaluates the sensitivity of their effective properties to mesoscale geometry. The findings show that analytical and sub-unit cell geometries provide reasonable approximations of full-scale predictions for effective thermal properties of production composites.

Summary: In order to meet the diversified requirements for polymer-based composites in modern electronic devices and electrical systems, the simultaneous enhancement of thermal-electrical-mechanical properties is a great challenge. The gradient structured composites, designed by adjusting the distribution of temperature, electric and stress fields in polyethylene (PE) based composites with different Al2O3 contents, demonstrated superior through-plane thermal conductivity, high breakdown strength, and good tensile strength. Finite element simulation provided evidence for the action mechanism on gradient structure regulating temperature and electric field. The strategy of constructing gradient structure provides a feasible route to meet the comprehensive performance requirements of PE based composites in massive manufacture scenario for practical insulation applications.

Summary: Utilizing organic structures to combine with TiO2 is an effective strategy for improving the photo-catalytic performance of TiO2. However, there is limited research on the impact of modulation at the organic molecular level for COF construction on the optical and electronic features of TiO2-COF heterostructures. In this study, a nitrogen-rich covalent organic framework (COF) was covalently integrated with amino-propyltriethoxysilane modified TiO2 (APTES-TiO2) through a Schiff-base reaction. The hybridized TiO2@TMP-COF with honeycomb-like morphology showed enhanced intramolecular charge transfer and photocatalytic CO2 reduction reaction (CO2RR) compared to the structure-similar COF established hybrid, TiO2@TM-COF. The study demonstrates the potential of creating heterostructures to improve light absorption and charge delivery in photocatalysis.

Summary: Compared to traditional single-axis motors, reluctance spherical motors (RSMs) can generate rotational torque in three spatial latitudes on a single motor, enabling three degrees-of-freedom (DOF) motion. This paper addresses the problem of consuming huge computational resources and long computation time in calculating the torque of RSM using the finite element method (FEM) by developing a torque model using the virtual work method. The results show that this method greatly reduces the amount of computing and simulation work with accurate modeling, providing a theoretical basis for the study of energization strategies and real-time control of RSM.

By using magnetron sputtering, columnar and zig-zag y-Mo2N thin-film electrodes were prepared, with the latter exhibiting a 4 times higher capacitance than the former. Both electrodes showed excellent cycling stability and the zig-zag y-Mo2N electrode demonstrated a higher power density and volumetric capacitance compared to the columnar y-Mo2N electrode. Additionally, the zig-zag y-Mo2N supercapacitors displayed mechanical flexibility up to a bending angle of 107 degrees.

Summary: In this study, Z-scheme ZnFe2O4-SrTiO3 nanocomposite was prepared and used for tetracycline hydrochloride (TCH) degradation and CO2 conversion. The nanocomposite showed significantly higher TCH degradation efficiency and CO2 photoreduction activity compared to pure ZnFe2O4 and SrTiO3. The enhanced activities were attributed to improved solar energy utilization and efficient electron-hole pair separation through a Z-scheme charge transfer model. The results suggest that ZnFe2O4-SrTiO3 nanocomposite has great potential for wastewater purification and CO2 reduction to renewable solar fuels.

Summary: In this study, Fe doped Bi2O2S nanosheets were synthesized for TCH photo-Fenton degradation. The optimized 2mol%Fe-BOS achieved greatly enhanced TCH degradation efficiency up to 81.01% under visible light irradiation. The enhanced catalytic performance of Fe-BOS was mainly attributed to the migration of photoinduced electrons to Fe3+ to generate Fe2+ and the rapid production of hydroxyl radicals (center dot OH) via the reaction between Fe2+ and H2O2.

Summary: In this study, a potential regulator of HSAF biosynthesis, RecX, was identified. Deletion of recX increased HSAF production, while overexpression of recX suppressed HSAF production. It was found that RecX directly binds to the promoter region of the lafB gene to inhibit its transcription and thus decrease HSAF production in L. enzymogenes.

Summary: In this study, we propose a method to encapsulate rhodium nanoparticles (NPs) on a palladium metallene film using a bromine initiator for catalyzing both the oxidation and reduction reactions. The Rh/Pd film exhibits excellent hydrogen evolution and hydrazine catalytic activities due to its abundant active sites and rapid charge transfer rate. In the hydrazine-assisted water splitting system, the Rh/Pd film only requires a low overpotential to produce hydrogen.
