Strain sensing is one of the important functions of intelligent fabric, which can transform the external stress (or strain) into visible electrical signals and monitor the characteristics of human physiology and motion. At present, the flexible strain sensor has low sensitivity, small strain range and unstable performance after repeated stretching. In this work, core-spun yarns with polyurethane (PU) filament as core and long silver nanowires (AgNWs) loaded cotton fiber as shell was fabricated by spinning technology. The results showed that when the loading of AgNWs was 10 wt%, the strain range of the PU/cotton@AgNWs core-spun yarn was 0-60%, the gauge factor of 12.6 was linear, and the strain sensing and mechanical properties were stable after repeated stretching. This strain sensing elastic core-spun yarns constructed by spinning technology could be used as one of the important materials for intelligent wearable devices. © 2021 Institute of Physics Publishing.

polymerized poly(1,3-dioxolane) (PDOL) electrolytes endow excellent interfacial contact and satisfactory compatibility in lithium metal batteries (LMBs). However, their limited oxidative stability hinders compatibility with high-voltage cathodes. Herein, an effective molecular weight modulation-induced strategy via multifunctional subnanowires (SNWs) was proposed to realize the superior oxidative stability of PDOL electrolytes with narrow molecular weight distribution (MWD). Specifically, the ring-opening polymerization of DOL was promoted by oxygen vacancies (Ov) on SNWs, which enhanced the monomer conversion rate. Simultaneously, the polymerization speed during the process was regulated by the weak adsorption of monomers induced by protonated oleylamine (PO). Furthermore, the dual Lewis acid sites (Ov and PO) of the SNWs facilitate lithium salt dissociation, releasing more movable Li for transport. Thus, the SNWs-induced polymerized PDOL electrolytes with an MWD of 1.42 exhibit remarkable oxidative stability exceeding 5.1 V while achieving a lithium-ion transference number of 0.81. Consequently, the assembled NCM811||Li cells maintain a stable operation for 100 cycles at 4.5 V with a capacity retention rate of 89.2%. This research first modulates the MWD of polymerized PDOL electrolytes using subnanowires to enhance their oxidative ability, presenting a unique strategy to inspire the development of high-performance LMBs.

Phase engineering is a critical strategy in electrocatalysis, as it allows for the modulation of electronic, geometric, and chemical properties to directly influence the catalytic performance. Despite its potential, phase engineering remains particularly challenging in thermodynamically stable perovskites, especially in a 2D structure constraint. Herein, we report phase engineering in 2D LaNiO 3 perovskite using the strongly non-equilibrium microwave shock method. This approach enables the synthesis of conventional hexagonal and unconventional trigonal and cubic phases in LaNiO 3 by inducing selective phase transitions at designed temperatures, followed by rapid quenching to allow precise phase control while preserving the 2D porous structure. These phase transitions induce structural distortions in the [LaO] + layers and the hybridization between Ni 3 d and O 2 p states, modifying local charge distribution and enhancing electron transport during the six-electron urea oxidation process (UOR). The cubic LaNiO 3 offers optimal electron transport and active site accessibility due to its high structural symmetry and open interlayer spacing, resulting in a low onset potential of 1.27 V and a Tafel slope of 33.1 mV dec −1 for UOR, outperforming most current catalysts. Our strategy features high designability in phase engineering, enabling various electrocatalysts to harness the power of unconventional phases.

In this study, the role of microstructure in tailoring the mechanical properties and corrosion behaviors of as-rolled dilute Mg–Bi binary alloys(MB-x, where x = 0.2 and 0.8 wt.%) without/with Mg3Bi2 phase was systemically explored. The MB-0.8 alloy with Mg3Bi2 phases exhibited superior strength, ductility, and anticorrosion synergy (with a tensile yield stress = of 235 MPa, ultimate tensile strength = of 285 MPa, elongation = of 10.3%, and corrosion rate stabilized at 0.105 mm/y). Strength–ductility synergy was achieved owing to the grain boundary strengthening and activation of prismatic and/or pyramidal slip systems. The transformation of the corrosion mode inhibited the corrosion of the MB-0.8 alloy. Therefore, it provides an effective strategy for developing superior comprehensive performance of Mg alloys. © 2023, The Authors. All rights reserved.

In this paper, we investigate the nonautonomous bright/dark solitons in a quasi-one-dimensional spin-1 Bose-Einstein condensates through a three coupled Gross-Pitaevskii (GP) system with space-time-dependent external potential and temporally modulated gain/loss distributions. Based on the Hirota bilinear method, we analytically construct the bright soliton solutions when the coupled GP system exhibits attractive interactions, while we obtain the dark soliton solutions when the coupled GP system exhibits repulsive interactions. The influence of spatiotemporal modulated external potentials, such as the gain/loss distribution Γ(t), on bright/dark soliton dynamics is analyzed in detail via the analytical solutions. By taking different Γ(t), we obtain different types of bright solitons, including periodic, dromion-like and parabolic solitons, and also derive dark solitons on different backgrounds, such as periodic, parabolic and kink backgrounds. We analyze the regulatory effects of different wavenumber ratios on the attraction and squeezing of bound-state solitons. Through the asymptotic analysis, we find that the interactions between two solitons are elastic. In addition, we conduct research on the forward and inverse problems of the above results via the parallel hard-constraint physical informed neural network (phPINN) method. The predicted solitons and potential functions are in good agreement with the exact solitons and potential in the system. © 2024, The Authors. All rights reserved.

In photocatalysis, reducing the exciton binding energy and boosting the conversion of excitons into free charge carriers are vital to enhance photocatalytic activity. This work presents a facile strategy of engineering Pt single atoms on a 2D hydrazone-based covalent organic framework (TCOF) to promote H2 production coupled with selective oxidation of benzylamine. The optimised TCOF-Pt SA photocatalyst with 3 wt% Pt single atom exhibited superior performance to TCOF and TCOF-supported Pt nanoparticle catalysts. The production rates of H2 and N-benzylidenebenzylamine over TCOF-Pt SA3 are 12.6 and 10.9 times higher than those over TCOF, respectively. Empirical characterisation and theoretical simulation showed that the atomically dispersed Pt is stabilised on the TCOF support through the coordinated N1-Pt-C2 sites, thereby induing the local polarization and improving the dielectric constant to reach the low exciton binding energy. These phenomena led to the promotion of exciton dissociation into electrons and holes and the acceleration of the separation and transport of photoexcited charge carriers from bulk to the surface. This work provides new insights into the regulation of exciton effect for the design of advanced polymer photocatalysts. © 2023 Wiley-VCH GmbH.

Sponge-based FeS x triggers enhanced and durable water decontamination from Cr(VI): Accelerated electron transfer and slow-releasing property

引用

Environmental Research 2025年 283卷

作者： Shou Mei Longjie Liu Yiqing Du Rongling Wang Ziyi Zhan Aoxue Qin Shenglan Zhao Yuxuan Ye Yuwei Deng Qiang Li Fei Pan School of Resources and Environment Wuhan Textile University Wuhan 430200 China State Key Laboratory of New Textile Materials and Advanced Processing Wuhan Textile University Wuhan 430200 China

Developing strategies for efficient and durable reduction of Cr(VI) in wastewater is still a desirable and challenging task. Herein, we successfully load the iron-sulfur composite (FeS x ) uniformly on the melamine sponge (MS) through in-situ deposition to form a three-dimensional composite FeS x /MS. Compared with typical iron minerals (e.g., FeS 2 ), FeS x /MS was significantly better at removing Cr(VI) in water, with the removal rate increased from 14.78 % to 99.44 %. The reaction kinetics of FeS x /MS (0.1011 min −1 ) was 37 times that of FeS 2 (0.0027 min −1 ). SEM-EDS results showed that FeS x was uniformly loaded on the sponge, forming a high density of active sites. XPS analysis displayed that the proportion of SO 4 2− was increased from 39.22 % to 61.18 %, implying the involvement of FeS x /MS in the reduction of Cr(VI). Tafel scanning and cyclic voltammetry (CV) results confirmed that the enhanced reduction performance was attributed to the accelerated electron transfer and sufficient electron supply capability. Additionally, the deposition of Cr(OH) 3 on FeS x /MS is evidenced to be responsible for eliminating total Cr from water. The influence of water chemistry, i.e., pH, Cr(VI) concentration, and co-existed substances, on Cr(VI) removal during FeS x /MS treatment was systematically examined. The removal capacity of Cr(VI) in tap water, natural water, and industrial wastewater, is more than 90 %, suggesting a strong anti-interference ability of FeS x /MS. The rapid flow dynamic simulation experiment demonstrates that FeS x /MS can achieve efficient removal of Cr(VI) and slow-releasing of Fe. The removal rate of Cr(VI) reached 100 % in the first 10 cycles, whereas the final effluent concentration was only 0.14 mg/L. This study provides a rational design of corresponding approaches to deal with Cr(VI) pollution.

Path planning and tracking control are important modules of mobile robots, which have outstanding advantages in improving the flexibility of mobile robots. However, in the existing applications, these two modules are usually processed separately, which makes the obstacle avoidance process of the mobile robot uncontrollable and reduces the adaptability of the application scenario. In order to realize collision-free high-precision trajectory tracking control of mobile robots in dynamic scenes, this paper proposes an adaptive MPC control method based on curvature constraints, which can improve the safety of operation and reduce the chattering caused by unreasonable paths in the process of operation. Firstly, according to the kinematic constraints of general mobile robots, the constraint model of mobile robot path planning is constructed. At the same time, the adaptive parameter adjustment rules are adopted to realize the balance between the calculation efficiency and the control cycle. Finally, a smooth safe path is obtained by re-fitting the planned path and reprocessing the nodes with excessive curvature. Compared with traditional methods, the proposed method has better advantages.

In the framework of the model of a spatially non-uniform Bose-Einstein condensate with helicoidal spin-orbit (SO) coupling, we find abnormal Peregrine solitons (PSs) on top of flat and periodic backgrounds, with ultra-high amplitudes. We explore the roles of the SO coupling strength and helicity pitch in the creation of these anomalously tall PSs and find that their amplitude, normalized to the background height, attains indefinitely large values. The investigation of the modulation instability (MI) in the same system demonstrates that these PSs exist in a range of relatively weak MI, maintaining the feasibility of their experimental observation.

In response to the green development trend of the textile and dyeing industry, it is essential to reduce environmental pollution and resource waste during the inkjet printing process. In this study, alkali-resistant disperse dye inks with high color fastness and stability were prepared using C.I. Disperse Blue 291, dispersant 85A, alcohol ether carboxylate, fatty alcohol polyethylene glycol ether, and polyvinylpyrrolidone. The performance of the prepared disperse dye ink was systematically tested and analyzed to determine the optimal formulation. The impact of each component in the ink on its physicochemical properties was investigated, along with the ink's alkali resistance, printing performance, and fixation process. The experimental results demonstrate that the formulated disperse dye ink exhibits excellent performance under alkaline conditions, enabling direct inkjet printing on polyester fabrics with good fixation. Specifically, after treatment with 2.5 wt% NaHCO₃ solution, the ink retained over 90% of its K/S value on polyester fabric. Under the curing conditions of 200 °C and 90 s, the printed fabric exhibited a relatively higher K/S value. Additionally, the inkjet-printed fabric showed excellent fastness and clear printed patterns. This study provides foundational research data and accumulated experience for the development of alkali-resistant disperse/active inkjet printing inks in the future.
