Wearable textile-triboelectric nanogenerators (t-TENGs) faced impediments in terms of the inadequate heat dissipation and moisture permeability performance. Specifically, actively heat-dissipating TENG devices exhibited intricacies, while passively heat-dissipating t-TENGs were considered unsatisfactory in sustaining optimal body temperature ranges for comfort. Herein, solvent-free titanium dioxide nanofluids (TiO2 nfs) were prepared to in-situ enhance the radiation cooling performance of electrospun TiO2 nfs@cellulose acetate (TiO2 nfs@CA) t-TENGs by grafting flexible chains on the TiO2 surface. TiO2 in the core layer of TiO2 nfs enhanced the infrared emission, hydrophilicity, and dielectric properties of TiO2 nfs@CA t-TENGs. Moreover, TiO2 nfs demonstrated a phase transition by absorbing energy within the physiological temperature ranges of the human body. TiO2 nfs enhanced the infrared emission, hydrophilicity, and dielectric properties of TiO2 nfs@CA t-TENGs by grafting flexible long chains ion on the TiO2 surface. The large-scale fabricated TiO2 nfs@CA membranes showcased remarkable radiation cooling performance (dropped 4 °C ~ 8 °C under 45 °C environments) in authentic and humid environments (like indoors, house and car). And TiO2 nfs@CA endowed a substantial enthalpy change within body temperature ranges, manifesting an exceptionally comfortable skin temperature (34 °C ~ 38 °C) even under scorching sunlight. Besides, TiO2 nfs@CA t-TENGs accurately monitored and pridicted foot movements in humid and enclosed environments by support vector machine (SVM). This made it promising as self-powered wearable devices. TiO2 nfs@CA t-TENGs provided a novel strategy for large scale fabricating of t-TENGs with comfort. © 2024, The Authors. All rights reserved.

Aqueous zinc batteries offer significant potential for large-scale energy storage, wearable devices, and medium-to low-speed transportation due to their safety, affordability, and environmental friendliness. However, the uneven zinc deposition at the anode side caused by localized reaction activity from the passivation layer presents challenges that significantly impact the battery's stability and lifespan. In this study, we have proposed an expandable and maneuverable gel sustained-release (GSR) treatment to polish the Zn metal, which in situ converts its native passivation layer into a composite interphase layer with nanocrystal zinc phosphate and flexible polyvinyl alcohol. Such a thin and uniform interface contributes to fast and homogeneous Zn ion transport and improved anti-corrosion ability, enabling uniform zinc deposition without dendrite growth and thereby improving the battery performance with high-rate ability and long cycle life. This GSR treatment method, characterized by its simplicity, low cost, and universality, facilitates the widespread application of aqueous zinc batteries. © 2025 Institute of Process Engineering, Chinese Academy of Sciences

The Forming Mechanism and Optimizing of Natural Polymer Foam Based on Magnolol Extracted from Chinese Herbal Medicine

Magnolol a Chinese medicinal herb that has been used for treating cough, phlegm and inflammation for a thousand years. Appreciating its low absorption rate that limits its use, there is need to develop porous magnolol foams that are light weight, low density, portable while maintaining tissue integrity to expand its application. This study proposes an innovative method for creating a biocompatible foam through a one-pot process involving reacting magnolol with sulfhydryl compounds, utilizing a thiol-ene click reaction to create a foam. Various foams were systematically formulated by adjusting the degrees of cross-linking, concentrations of the foaming agent 2,2'-azobis(2-methylpropionitrile) (AIBN), and the temperature and pressure conditions during the foaming. AIBN acted both as a blowing agent and initiator, triggering cross-linking in the polymer solution by releasing free radicals and nitrogen gas. This initiated rapid expansion when a critical viscosity threshold was reached, ultimately curing the foam. The optimal foaming efficiency was achieved when the molar ratio of allyl to mercapto groups was maintained at 1:1, pentaerythritol tetrakis(3-mercapto-propionate) (PETMP) identified as the optimal sulfhydryl compound. Increasing the dosage of AIBN enhanced gas generation, further expanding foam volume, pore size and porosity, the foam is lightest when the amount of AIBN is 7.5%. When magnolol-based foams were prepared under sealed conditions at 100°C, without external pressure, they exhibited large, uniformly distributed pores and excellent water-absorbing properties. Moreover, the resulting foams demonstrated remarkable thermal stability and resilience. These findings offer a new design strategy for engineering high-performance functional magnolol foams with high biomass content. © 2025, The Authors. All rights reserved.

Carbazole-based self-assembled molecules have been widely adopted as hole-transporting layers（HTLs） in high-performance organic solar cells（OSCs）. However, their practical implementation has been constrained by their limited concentration in solutions and poor solvent tolerance. Herein, to address these limitations, we designed two novel trimeric molecules（TPACz-1and TPACz-2） that synergistically integrate the structural merits of small molecules with the processing advantages of ***, TPACz-2 showed exceptional hole-transporting capacity with uniform coverage on indium tin oxide（ITO） substrates,coupled with robust processability characterized by an extended concentration tolerance range(0.2–1.0 mg mL-1) and compatibility with a broad range of solvents. Binary OSCs based on TPACz-2 showed an excellent power conversion efficiency（PCE） of 19.65% with a short-circuit current density of 27.49 mA cm-2and a fill factor of 80.9%. At the same time, the corresponding ternary devices exhibited a high PCE exceeding 20%. Furthermore, the TPACz-based devices demonstrated superior ambient stability, retaining ～80% of their initial PCE after 680 h at 25% relative humidity, substantially outperforming conventional PEDOT:PSS-based counterparts. This work offers valuable guidance and highlights the crucial role of oligomeric molecular design as a pivotal strategy for the development of innovative HTLs in OSCs.
