To harness the abundant lithium (Li)-containing aqueous resources and meet the growing demand for Li, membrane-based processes for selective Li recovery have garnered extensive attention. The incorporation of sulfonate groups into membranes is a crucial strategy for fine-tuning ion selectivity, which has been widely used in nanofiltration and electrodialysis for Li separation;however, its potential in the membrane capacitive deionization (MCDI) process for Li recovery remains largely unexplored. This study bridges this research gap by integrating activated carbon (AC) electrodes of capacitive deionization (CDI) with sulfonate poly ether ketone (SPEK) membranes, featuring varying degrees of sulfonation (SPEK-20, SPEK-40, and SPEK-60), and evaluating their Li recovery performance using Li/M (M representing competing cations such as Na, K, Mg, Ca) binary solutions. The synthesized membrane electrodes underwent thorough characterization, confirming the successful formation of sulfonate groups in the SPEK membrane, revealing the SPEK layer with a cross-section thickness below 10 µm, and identifying the hydrophilicity of the AC/SPEK electrode surface. The MCDI results unveiled the significant impact of incorporating SPEK membranes on Li recovery performance in monovalent-cation competing feeds compared to bare AC electrodes, boosting the Li removal rate and Li selectivity in Li/K feed by over 210% and 120%, respectively. Meanwhile, SPEK membranes demonstrate a preferable affinity for capturing and releasing divalent ions, with the variations in sulfonation degree exerting a greater influence on cases involving divalent cations. © 2024, The Authors.

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

Pickering emulsion loading essential oil has demonstrated a promising strategy as delivery system in food preservation, but localization in stability and antimicrobial activity limits application. In this study, Pickering emulsions co-loaded with tannic acid and cinnamon essential oil (ZTC) have been developed based on zein and tannic acid complexes (ZT) mediated interfacial engineering. Fourier transform infrared, fluorescence spectroscopy, and molecular docking results indicated tannic acid altered the structural of zein. Interfacial tension results indicated that tannic acid accelerated the adsorbed speed of zein particles by decreased interfacial tension (11.99-9.96 mN/m). ZT5 formed a viscoelastic and dense layer in oil-water interface than that for other ZTs, which improved stability and control release performance of ZTC. Furthermore, the ZTC showed an effective antimicrobial activity against spoilage organisms Pseudomonad paralactis MN10 and Lactobacillus sakei VMR17. These findings provide new insight for developing co-loaded multiple antimicrobial agents within Pickering emulsion as a delivery system. © 2023, The Authors. All rights reserved.

Cu9S5 possesses high hole concentration and potential superior electrical conductivity as a novel p-type semiconductor, whose biological applications remain largely unexploited. Encouraged by our recent work that Cu9S5 has enzyme-like antibacterial activity in the absence of light, which may further enhance the near infrared (NIR) antibacterial performance. Moreover, vacancy engineering can modulate the electronic structure of the nanomaterials and thus optimize their photocatalytic antibacterial activities. Here, we designed two different atomic arrangements with same VCuSCu vacancies of Cu9S5 nanomaterials (CSC-4 and CSC-3) determined by positron annihilation lifetime spectroscopy (PALS). Aiming at CSC-4 and CSC-3 as a model system, for the first time, we investigated the key role of different copper (Cu) vacancies positions in vacancy engineering toward optimizing the photocatalytic antibacterial properties of the nanomaterials. Combined with the experimental and theoretical approach, CSC-3 exhibited stronger absorption of surface adsorbate, higher separation of photogenerated charge carriers, and lower reaction active energy than those of CSC-4, leading to the generation of abundant ·OH for attaining rapid drug-resistant bacteria killed and wound healed under NIR light irradiation. This work provided a novel insight for the effective inhibition of drug-resistant bacteria infection via vacancy engineering at the atomic-level modulation. © 2022, The Authors. All rights reserved.

Microbial electrolysis cells (MECs) are a new bio-electrochemical method for converting organic matter to hydrogen gas (H-2). Palm oil mill effluent (POME) is hazardous wastewater that is mostly formed during the crude oil extraction process in the palm oil industry. In the present study, POME was used in the MEC system for hydrogen generation as a feasible treatment technology. To enhance biohydrogen generation from POME in the MEC, an empirical model was generated using response surface methodology (RSM). A central composite design (CCD) was utilized to perform twenty experimental runs of MEC given three important variables, namely incubation temperature, initial pH, and influent dilution rate. Experimental results from CCD showed that an average value of 1.16 m(3) H-2/m(3) d for maximum hydrogen production rate (HPR) was produced. A second-order polynomial model was adjusted to the experimental results from CCD. The regression model showed that the quadratic term of all variables tested had a highly significant effect (P < 0.01) on maximum HPR as a defined response. The analysis of the empirical model revealed that the optimal conditions for maximum HPR were incubation temperature, initial pH, and influent dilution rate of 30.23 ?, 6.63, and 50.71%, respectively. Generated regression model predicted a maximum HPR of 1.1659 m(3) H-2/m(3) d could be generated under optimum conditions. Confirmation experimentation was conducted in the optimal conditions determined. Experimental results of the validation test showed that a maximum HPR of 1.1747 m(3) H-2/m(3) d was produced.

In recent years, nanophononic metamaterials (NPMs) have attracted great interest from researchers. Theoretical calculations and experimental studies have revealed the mechanism of reducing thermal conductivity through localized resonant hybridization. In addition, researchers have studied the effects of nanopillar height, spacing, and atomic mass in nanopillars on surface localization. The atomic mass mismatch in nanopillars has important application in practice. Taking the silicon-based nanopillar structure as an example, this paper studies the effects of atomic mass mismatch in nanopillars on surface localization effect and heat flux. The results show that atomic mass mismatch in nanopillars can enhance the surface localization effect, and the greater the difference in atomic mass in nanopillars, the stronger the surface localization. Finally, the effect of atomic mass mismatch in nanopillars on heat flux was calculated by nonequilibrium molecular dynamics. The results of this study can provide useful guidance for the design of nanoscale heat flux regulation devices.

Journal of Energy Storage 2025年 130卷

作者： Hang Zhang Ziran You Ruiting Wang Jianrong Liang Yachu Song Ying Gao Yanhao Duan Zhengzheng Li College of Chemical Engineering and Materials Science Tianjin University of Science and Technology Tianjin 300457 PR China Key Laboratory of Advanced Energy Materials Chemistry (Ministry of Education) Nankai University Tianjin 300071 PR China State Key Laboratory of Molecular Engineering of Polymers (Fudan University) Shanghai 200433 PR China State Key Laboratory of Bio-based Fiber Materials Tianjin University of Science & Technology Tianjin 300457 PR China

Advances in wearable technology have driven the development of flexible energy storage devices. Hydrogel electrolytes have been attempted to be applied in flexible supercapacitors for their high flexibility, good mechanical stability and ionic conductivity. However, due to factors such as the ordinary mechanical properties, poor adhesion and degradation of electrochemical properties at high and low temperatures of hydrogel electrolytes, their application in supercapacitors can be affected. Herein, Polyacrylamide/Polyvinyl alcohol/Chitosan quaternary ammonium salt (PAM/PVA/HACC, PPH) hydrogel electrolytes with multiple cross-linked network structures of chemical cross-linking, hydrogen bonding and electrostatic interactions were synthesized by one-pot method. The optimal PPH-0.15 hydrogel electrolyte has good tensile strength (977 kPa) and high ionic conductivity (43.23 mS cm −1 ). More importantly, the supercapacitor assembled from the PPH-0.15 hydrogel electrolyte shows high area capacitance of 183.44 mF cm −2 and high energy density of 16.31 μWh cm −2 , as well as excellent cyclic durability, with a capacitance retention of 81.8 % after 10,000 charge-discharge cycles. In addition, the prepared supercapacitor maintains good electrochemical performance under certain folding conditions and different temperature environments. This work possesses guiding significance for the preparation of hydrogel electrolytes with physical and chemical double cross-linking, and exhibits good application prospects in flexible energy storage devices.
