The stability and reversibility of Zn anode can be greatly improved by in situ construction of solid electrolyte interphase (SEI) on Zn surface via a low-cost design strategy of ZnSO 4 electrolyte. However, the role of hydrogen bond acceptor -SO 3 accompanying ZnS formation during SEI reconstruction is overlooked. In this work, we have explored and revealed the new role of -SO 3 and ZnS in the in situ formed sulfide composite SEI (SCSEI) on Zn anode electrochemistry in ZnSO 4 aqueous electrolytes. Structure characterization and DFT demonstrate that the introduction of -SO 3 can not only reduce the dehydration energy of [Zn(H 2 O) 6 ] 2+ , but also enhance the stability of the ZnS/Zn interface and homogenize the ZnS/Zn interface electric field, thereby significantly improving the dynamic kinetics and uniform deposition of Zn 2+ . Owing to the synergistic effect of ZnS and -SO 3 , a high cycling stability of 1500 h with a cumulative-plated capacity of 7.5 Ah cm −2 at 10 mA cm −2 has been achieved within the symmetrical cell. Furthermore, the full cell with NH 4 V 4 O 10 cathode exhibits outstanding cyclic stability, exceeding 2000 cycles at 5 A g −1 and maintaining a Coulombic efficiency of 100 %. These new insights into anionic synergistic strategy could significantly enhance the practical application of zinc-ion batteries.

Sintering inhibition of a catalyst at high temperatures is a challenge during heterogeneous catalysis. In this paper, we report that hexagonal boron nitride(h-BN) is an optimal material for anti-sintering γ-Al_(2)O_(3)-supported Pt nanoparticles(NPs) originating from the high thermal conductivity of h-BN. The high thermal conductivity of h-BN ensures maximal heat dissipation from Pt NPs to γ-Al_(2)O_(3),thereby causing both Ostwald ripening and particle coalescence of Pt NPs to be decelerated at elevated *** of Pt NP sintering is also shown in the reducible TiO^(2-)supported Pt NPs with the help of h-BN. The proposed anti-sintering strategy using thermal management is universal, providing new insight into the design of anti-sintering materials and structures for a wide range of applications in heterogeneous catalysis.

Polymer electrolytes incorporated with fillers possess immense potential for constructing the fast and selective Li + conduction. However, the inhomogeneous distribution of the fillers usually deteriorates the microdomain consistency of the electrolytes, resulting in uneven Li + flux, and unstable electrode-electrolyte interfaces. Herein, we formulate a solution-process chemistry to in situ construct gel polymer electrolytes (GPEs) with well-dispersed metal–organic frameworks (MOFs), leading to a uniform microdomain structure. Through the integration of X-ray computed tomography analyses and theoretical simulations, our research identifies that the improvement of microdomain consistency in GPEs is beneficial for enhancing its mechanical strength, homogenizing ionic/electronic field distribution and upgrading the interface stability with the elctrodes. Moreover, consistently spread MOFs bind effectively with Lewis-base anions of Li salts, enhancing Li + kinetics. Owing to these advantages, the developed GPEs achieve a high conductivity of 1.51 mS cm −1 and a Li + transference number of 0.66, resulting in exceptional cyclability of lithium metal electrodes (over 1800 hours). Additionally, the solid-state NCM811//Li pouch batteries exhibit an impressive capacity retention of 94.2 % over 200 cycles with an N/P ratio of 1.69. This study emphasizes the significant impact of microdomain structural chemistry on the advancement of solid-state batteries.

TiNi-based shape-memory alloys are known to exhibit a strain glass state under certain conditions, generally in the presence of high-density defects such as excess solute atoms or alloying elements, dislocations, and nanoprecipitates. In this paper, we report a strain glass transition in a nanocrystalline Ti50Ni35Pt15 alloy. The nanocrystalline strain glass state is achieved by a combined effect of high-density grain boundaries and high concentration doping of Pt atoms in the B2 matrix. The nanocrystalline Ti50Ni35Pt15 strain glass alloy showed a large near-complete progressive superelasticity with a recovery strain of about 6% and a low apparent Young's modulus of about 30 GPa in a wide temperature range of over 200 °C. In situ synchrotron x-ray diffraction measurement showed that the strain glass B2 [B2(SG)] phase experienced B2(SG)→R→B19 transformation upon loading and B19→B2(SG) upon unloading. The findings of this study provide insight for the development of nanocrystalline strain glass shape-memory alloys.

The rapid advancement of flexible electronics imposes escalating demands on high-performance thermoelectric materials, particularly in extreme environments such as fire rescue operations, where mechanical stability and multifunctionality must be synergistically integrated. This study, developed a polyimide (PI)-based core sheath thermoelectric fiber (PT-SCF) with adjustable pore networks using non-solvent induced phase separation assisted coaxial wet spinning technique. The fiber sheath layer uses PI as the substrate, and polyvinyl alcohol (PVA) as the pore regulator agent to regulate the pore size (∼1.77–3.23 µm), while the introduction of 2D MXene nanosheets endowed the fiber with the ability of temperature sensing (maximum output voltage of 7.9 mV). The fiber core layer combines thermoplastic polyurethane (TPU) and ultraviolet (UV) photosensitive materials (UVs) to achieve fiber damage detection through a UV light-driven mechanism. The optimized PT-SCF has excellent mechanical properties (4.1 MPa, (R-R0)/R0 2 = 0.99). In addition, the PT-SCF realizes fast high-temperature warning in 1.6 s. Its integration with a multi-level temperature threshold high-temperature warning system highlights its potential for applications in smart fire-fighting systems and wearable electronic devices. This work presents a novel approach for designing and developing multifunctional thermoelectric fibers tailored to various harsh environments. © 2025 Elsevier B.V.

We have developed a controlled-release drug carrier. Smartly controlled-release polymer nanoparticles were firstly synthesized through RAFT polymerization as the controlled-release core. The structural and particle properties of polymer nanoparticles were characterized by nuclear magnetic resonance spectroscopy (1H-NMR), scanning electron microscope (SEM) and X-ray spectroscopy (EDX). Mesoporous materials were selected as the shell materials to encapsulate the smart core as the stable shell. The mesoporous shell was characterized by transmission electron microscopy (TEM) and scanning electron microscope (SEM). All the results showed that a well-defined core-shell structure with mesoporous structure was obtained, and this controllable delivery system will have the great potential in nanomedicine.

A method for measuring and characterizing the surface exchange reaction rate of CO2 reduction reaction (CO2RR) with porous two-phase cathode in solid oxide electrolysis cell (SOECs) was established. This method is based on electrical conductivity relaxation (ECR) and applied to mixed electron-ion conducting Sr2Fe1.5Mo0.5O6−δ-Sm0.2Ce0.8O1.9 (SFM-SDC) composites, whose microstructure characteristics such as permeable probability, three-phase boundary (TPB) length, and surface area are determined through numerical simulation using scanning electron microscopy images. Analysis the ECR data with characteristic time distribution (DCT) model shows that the CO2RR process involves a combination of three steps: gas diffusion, surface exchange, and their interactions. The gas diffusion contributes 18–29 % of the total resistance CO2RR, demonstrating its significant in SOEC cathode reactions that take place in porous structures. Adding SDC generates additional active reaction sites of TPBs and thus effectively enhance the CO2RR rate with a strengthening factor up to 10. Meanwhile, the chemical surface exchange coefficient of CO2RR increases with the increase of TPB length, indicating that the presence of TPB significantly enhances the CO2RR surface reaction of porous composite cathode. © 2025 Elsevier B.V.

Polycyclic aromatic hydrocarbons (PAHs) are serious organic pollutions and important industrial raw materials which are abundant in fluid catalytic cracking (FCC) diesel. Therefore, it is necessary to find suitable approach to remove PAHs from FCC diesel under mild condition. In this study, a series of deep eutectic solvents (DESs) were designed and synthesized as PAHs extractants. The tetraoctyl ammonium bromide (TOAB) and ethylene glycol (EG) with the molar ratio of 1:2, TOAB:2EG, exhibited great single extraction efficiency towards naphthalene (NAP, 55.6 %) and anthracene (ANT, 92.3 %). The orthogonal experiment proved the alkyl chain length of quaternary ammonium salt influenced PAHs extraction mostly. The high extraction efficiency was attributed to the hydrogen bonds, p-π and π-π interactions between PAHs and DESs. This work advances the DESs as PAHs extractants with high extraction efficiency and broadens the applications of DESs. © 2025 Elsevier B.V.
