The low electrical transport performance of flexible thermoelectric (TE) films is the bottleneck that restricts the development of in-plane heat dissipation technology based on the Peltier effect. The architectonics of magnetic units in TE materials have been proven to be an effective method to improve the efficiency of TE conversion. In this study, a series of Bi0.5Sb1.5Te3 (BST)/Fe/BST thermoelectromagnetic (TEM) films were successfully prepared by ordered architectonics of ferromagnetic Fe nanoparticles (Fe-NPs) as magnetic units with different distribution shapes between two layers of BST/epoxy films through screen-printing combined with hot-pressing curing. The study focused on the effects of the architectonic shapes of Fe magnetic units on the microstructure and electrothermal transport properties of TEM films. The ordered architectonics of magnetic units could optimize the carrier transport pathways and reduce carrier scattering due to the altered carrier trajectories induced by the magnetic field generated by the Fe magnetic unit, which has been confirmed by the magnetoresistance test, thus effectively enhancing σ. The introduction of the Fe magnetic unit preserved a large α through magnetic scattering and spin entropy contributions. The TEM film with Fe magnetic units patterned as rhombic shapes (BST-RhoFe-BST film) realized a 36.5% enhancement in the maximum power factor (PF), attributing to the largest negative magnetoresistance. The cooling temperature difference of the single-leg film device fabricated by the BST-RhoFe-BST film reached 1.8 K, 125% higher than that of the device fabricated by the BST-BST film. Furthermore, the cascade device based on the TEM film realized a temperature drop of 2.8 K and exhibited excellent in-plane heat dissipation capability. This work reveals that the ordered architectonic shapes of magnetic units could effectively regulate the electrothermal conversion performance of TE films, and the magnetoresistance theory can reve

Urea oxidation is a significant reaction for utilizing urea-rich wastewater or human urine as sustainable power sources which can ease the water eutrophication while generate electricity. A direct urea-hydrogen peroxide fuel cell is a new kind of fuel cell employing urea as fuel and hydrogen peroxide as oxidant which possesses a larger cell voltage. Herein, this work tries to promote the kinetics process of urea oxidation by preparing low-cost and high-efficient NiCo2S4 nanowires modified carbon sponge electrode. The carbon sponge used in this work with a similar three-dimensional multi-channel structure to Ni foam, is prepared by carbonizing recycled polyurethane sponge which is also a process of recycling waste. The performance of the prepared catalyst in an alkaline solution is investigated in a three-electrode *** the introduction of Co element to the catalyst, a reduced initial urea oxidation potential and a high performance are obtained. Furthermore, a direct urea-hydrogen peroxide fuel cell is assembled using the NiCo2S4 nanowires modified carbon sponge anode. Results indicate that the prepared catalyst provides a chance to solve the current problems that hinder the development of urea electrooxidation(high initial urea oxidation potential, low performance, and high electrode costs).

High entropy metallic glasses（MGs） have attracted tremendous attentions owing to high entropy that benefits the probing of new MG-forming systems. However, the micro-formability of high entropy MGs is lack of investigation in comparison with these conventional MG counterparts, which is crucial to the development of this kind of metallic alloys. In this work, the thermoplastic mciro-formability of TiZrHfNiCuBe high entropy MG was systemically investigated. Time-Temperature-Transformation（TTT）curve was first constructed based on isothermal crystallization experiments, which provides thermoplastic processing time of the supercooled high entropy MGs. By comparison with the deformation map,Newtonian flow was found beneficial to the thermoplastic formability. While the thermoplastic forming becomes arduous with reducing mould size to tens micrometer, because of the strong supercooled TiZrHfNiCuBe high entropy MG（fragility = 27）. Fortunately, the micro-formability of TiZrHfNiCuBe high entropy MG could be improved by vibration loading, as demonstrated by finite-element-method simulation. Our findings not only systemically evaluate the thermoplastic micro-formability of high entropy MG, but also provide fundamental understanding of the phenomenon.

Conductive hydrogel has garnered significant fascination for its potential as wearable sensor. However, designing a wearable sensor with excellent electrical conductivity, self-healing capability, mechanical strength and recyclability is still difficult to accomplish. Herein, a multifunctional composite hydrogel was fabricated via a one-pot method with cellulose microcrystals (CMCs) and MXene. The introduction of CMCs to the hydrogel composite provided mechanical strength and assisted in homogeneous distribution of MXene resulting the high electrical conductivity. The subsequently prepared conductive composite hydrogel exhibited improved tensile strength (87.4 kPa) and elongation at break (424 %) with optimum composition, outstanding electrical conductivity (1.11 S/cm) and quick electrical self-healing efficiency without external stimuli. The temperature responsiveness of the conductive composite hydrogel was mainly accredited for reducing interfacial thermal resistance ensuing of continuous heat conduction pathways. It also demonstrated the notable fire resistance offering quick fire-warning signals within ∼1 sec. The developed conductive composite hydrogel could monitor subtle human movements efficiently as well as possessed the ability to track human body temperature, indicating effective means of electronic skin (E-skin) for smartphone interfacing. This work introduces a feasible approach in designing an electrically conductive, biodegradable wearable composite hydrogel with potential applications as versatile motion, temperature and fire sensor. © 2025 The Authors
