Ice accretion on wind turbine blades critically compromises energy conversion efficiency (≤80 %) and structural integrity. Herein, we propose a fluorine-free multifunctional coating integrating synergistic photothermal and superhydrophobic mechanisms for sustainable anti-icing applications. The rationally designed P-CNT/PDMS/EP composite, synthesized via a single-step blade-coating technique, demonstrates simultaneous ultra-repellency (150.43° static contact angle, 3.94° sliding angle) and efficient solar energy conversion (94.88 % broadband absorption). Under simulated extreme conditions (−20 °C, 15 m·s−1 crosswinds), the coating achieves rapid ice shedding within 240 s through photothermal activation while maintaining 95 % hydrophobicity retention after mechanical abrasion. Notably, ice accumulation reduces to 2 % of uncoated surfaces, coupled with exceptional environmental stability (ΔCA © 2025 Elsevier B.V.

Five negatively charged organic compounds with different structures, sodium methane sulfonate(MS), sodium benzene sulfonate(BS), sodium 6-hydroxynaphthalene-2-sulfonate(NSS), sodium dodecyl sulfate(SDS), and sodium dodecyl benzene sulfonate(SDBS), were used to examine the fouling of an anion exchange membrane(AEM) in electrodialysis(ED),to explore the effect of molecular characteristics on the fouling behavior on the AEM and changes in the surface and electrochemical properties of the AEM. Results indicated that the fouling degree of the AEM by the different organics followed the order:SDBS > SDS > NSS > BS > MS. SDBS and SDS formed a dense fouling layer on the surface of the AEM, which was the main factor in the much more severe membrane fouling, and completely restricted the transmembrane ion migration. The other three organics caused fouling of the AEM by adsorption on the surface and/or accumulation in the interlayer of the AEM, and exhibited almost no influence on the transmembrane ion migration. It was also concluded that the organics with benzene rings caused more severe fouling of the AEM due to the stronger affinity interaction and steric effect between the organics and the AEM compared with organics with aliphatic chains.

This paper investigates the cooperative output regulation (COR) of nonlinear multi-agent systems (MASs) with long input delay based on periodic event-triggered mechanism. Compared with other mechanisms, periodic event-triggered control can automatically guarantee a Zeno-free behavior and avoid the continuous monitoring of triggered conditions. First, a new periodic event-triggered distributed observer, which is based on the fully asynchronous communication data, is proposed to estimate the leader information. Second, a new distributed predictor feedback control method is proposed for the considered nonlinear MASs with input delay. By coordinate transformation, the MASs are mapped into new coupled ODE-PDE target systems with some disturbance-like terms. Then, we show that the COR problem is solvable. At last, to further save the communication resource, a periodic event-triggered mechanism is considered in the sensor-to-controller transmission in every agent. A new periodic event-triggered filter is proposed to deal with the periodic event-triggered feedback data. The MASs with input delay are mapped into coupled ODE-PDE target systems with sampled data information. Then, Lyapunov-Krasovskii functions are constructed to demonstrate the exponential stability of the MASs. Simulations verify the validity of the proposed results. © 2024, CC BY-NC-ND.

The urgent demand for lithium resources has been advancing the development of highly efficient lithium extraction from brines. Aluminum-based lithium adsorbent, as the only one used in the Salt Lake industry, is limited in further improving the extraction efficiency due to the low adsorption capacity. Here, we develop a high-throughput screening framework via interpretable machine learning (ML) to rapidly determine high-performance modification strategies for the aluminum-based lithium adsorbent, avoiding the huge workload of traditional trial-and-error doping experiments in view of multiple doping schemes and the unique trade-off between performance and structural stability. Relying on the recommended modifications, a series of doped adsorbents are prepared and the structure stability and cyclic adsorption performance are verified, which match well with the uncovered correlation between dopant features and adsorption capacity. Experimental validations confirm the screened doped one exhibits an increased stable adsorption capacity by nearly 40% in various types of brine. These results indicate that ML-accelerated approach can significantly promote the upgrading of lithium resource adsorption industry in Salt Lakes.

Selective methanol oxidation reaction (MOR) to value-added formate can maximize the input energy utilization for water electrolysis by replacing the high onset-potential and kinetics sluggish oxygen evolution reaction. However, to date only first-row 3d transition metal oxides present the capacity of selective MOR, motivating the design of new kinds of electrocatalysts to further enhance the MOR performance. Herein, we show amorphous Nb2O5 as an efficient electrocatalyst, for the oxidation of methanol to formate, with a low operating potential of 1.47 V vs. RHE to achieve industry-relevant current densities (>100 mA cm-2) with a Faraday efficiency of ~100%. We demonstrate, via operando Raman measurements, this superior electrochemical MOR activity originated from the in-situ induced short Nb-O bonds from the amorphous structure, while the crystalline Nb2O5 fails to generate this active site resulting in a poor activity. This work may provide valuable insight for developing novel transition metal oxides for MOR catalysts. © 2023, The Authors. All rights reserved.

The study of ultra-high temperature ceramic materials, specifically zirconium diboride (ZrB2), is of great interest due to their potential applications in extreme environments, such as the aerospace and nuclear industries. This research aims to comprehend the reaction dynamics of ZrB2 powders in water vapor oxygen coupled environments, which is a common scenario in high-temperature applications. The study aims to provide a comprehensive insight into the behaviour of ZrB2 in a controlled water vapor oxygen environment, highlighting the two-stage reaction process and its implications for material stability and potential industrial applications. ZrB2 powders were used to investigate their reactivity in a hydrothermal kettle through a series of experiments. This study improves our understanding of ZrB2's reactivity and suggests its potential in applications such as hydrogen production. However, it also highlights the need for improved stability in such reactive environments. © 2024, The Authors. All rights reserved.

Dual activation pathways based on OH-functionalized alk-Ti 3 C 2 MXene/RuO x boosting the hydrogen generation

A meticulous design of the local environment at the interface between active species and the support, aimed at optimizing the adsorption of H 2 O molecules and BH 4 − anion, offers an ideal strategy for enhancing hydrogen generation via NaBH 4 hydrolysis through dual activation pathways. Theoretical predictions based on d-band center analysis and electron transfer calculations suggest that introducing -OH functional groups induce charge redistribution, enhancing charge concentration on alk-Ti 3 C 2 and facilitating the adsorption and activation of dual active species, H 2 O molecules and BH 4 − anion. Inspired by these predictions, the optimized alk-Ti 3 C 2 /RuO x catalyst demonstrates the highest catalytic activity, achieving a hydrogen generation rate (HGR) of 9468 mL min −1  g cat. −1 . Both experimental data and theoretical analyses confirm that the -OH functional groups promote charge enrichment on alk-Ti 3 C 2 , optimizing the adsorption of H 2 O molecules and BH 4 − anion, and reducing the dissociation energy barrier of the *OH H-TS intermediate. This dual activation pathways mechanism lowers the activation energy for NaBH 4 hydrolysis, significantly enhancing the HGR performance. These findings, guided by theoretical insights, establish alk-Ti 3 C 2 /RuO x as an efficient catalyst for NaBH 4 hydrolysis and provide a strong foundation for future hydrogen generation catalyst designs.
