In this study, a novel flowerball-like CdS/O-g-CN heterostructure was successfully synthesized using an in-situ solvothermal method and evaluated for its photocatalytic performance in methylene blue (MB) degradation, hydrogen (H) evolution, and photostability. Owing to its gradient band alignment, the heterostructure exhibits enhanced visible-light absorption and efficient separation of photogenerated charge carriers. Among the prepared structures, the optimized CdS/OCN-10 m demonstrated superior photocatalytic efficiency, completely degrading 10 mg/L of MB within 120 min under visible light. The apparent rate constant for MB degradation by CdS/OCN-10 m was calculated as 0.0123 min, which is approximately 2.5 times and 2.1 times higher than those of O-g-CN (0.00479 min) and CdS (0.0057 min), respectively. Moreover, CdS/OCN-10 m exhibited an outstanding hydrogen evolution rate of 48,000 μmol/g, outperforming pure CdS and O-g-CN by factors of 5.8 and 3.2, respectively. These enhanced properties were further confirmed through various characterization techniques, including photoluminescence (PL) spectroscopy, UV-vis diffuse reflectance spectroscopy (DRS), electrochemical impedance spectroscopy (EIS), and transient photocurrent response measurements. Importantly, the CdS/OCN-10 m photocatalyst showed excellent stability, retaining its flowerball-like morphology and exhibiting negligible performance loss over five photocatalytic cycles spanning 25 h, underscoring its strong resistance to photocorrosion.

Imide functionalization has been widely proved to be an effective approach to enrich optoelectronic properties of polycyclic aromatic hydrocarbons (PAHs). However, appending multiple imide groups onto linear acenes is still a synthetic challenge. Herein, we demonstrate that by taking advantage of a “breaking and mending” strategy, a linear pentacene tetraimides (PeTI) was synthesized through a three-step sequence started from the naphthalene diimides (NDI). Compared with the parent pentacene, PeTI shows a deeper-lying lowest unoccupied molecular orbital (LUMO) energy level, narrower band gap and better stability. The redox behavior of PeTI was firstly evaluated by generating a stable radical anion specie with the assistance of cobaltocene (CoCp 2 ), and the structure of the electron transfer (ET) complex was confirmed by the X-ray crystallography. Moreover, due to the presence of multiple redox-active sites, we are able to show that the state-of-the-art energy storage performance of the dealkylated PeTI (designated as PeTCTI) in organic potassium ion batteries (OPIBs) as an anode. Our results shed light on the application of multiple imides functionalized linear acenes, and the reported synthetic strategy provides an effective way to get access to longer nanoribbon imides with fascinating electronic properties.

Carbide boronizing is a promising approach to obtain fine grained boron carbide based ceramics with improved mechanical properties. In this work, reaction process, microstructural characteristics and mechanical properties of BxC-TaB2(x = 3.7, 4.9, 7.1) ceramics were comprehensively investigated via this method. Dense BxC-TaB2 ceramics with refined microstructure were obtained from submicro tantalum carbide and boron powder mixtures at 1800℃/50 MPa/5 min by spark plasma sintering. The stoichiometry of boron carbide was determined from lattice parameters and Raman shift. It was found that uniformly distributed TaB2 grains in the BxC matrix is favor of the densification process and restricting grain ***, planar defects with high density were observed from the as-formed B7.1 C grains and transient stress was considered to contribute to the densification involved with plastic deformation. Microstructural observations indicate the dissolution of oxygen in the TaB2 lattice and most of the B7.1 C/TaB2 phase boundaries were clean. Owing to the highly faulted structure and finer grain size, as-obtained BxC-TaB2 ceramics exhibit high Vickers hardness(33.3–34.4 GPa at 9.8 N) and relatively high flexural strength ranging from 440 to 502 MPa.

Improving the oxygen transport ability without sacrificing proton conductivity in cathode catalyst layer is an essential way to increase the performance, thereby reducing platinum usage of proton exchange membrane fuel cells (PEMFCs). Herein, we report the influence of equivalent weight of dioxole-contained highly oxygen permeable perfluorosulfonic acid ionomers as catalyst binder and proton conductor in cathode catalyst layer on the performance of PEMFC. The results reveal that the increase in the fraction of dioxole segments leads to the enhanced oxygen permeation but the decreased proton conductivity in catalyst layer. With optimization of equivalent weight of the synthesized ionomers, the accordingly assembled cell with platinum loading of 0.125 mg cm−2 for both anode and cathode exhibits an improved concentration polarization, leading to an increased peak power density by 166 mW cm−2 at current density of 2900 mA cm−2 compared to Nafion ionomer-based PEMFC at 2800 mA cm−2 using hydrogen and air as reactant gases. © 2025 Elsevier Ltd

Major advances in molecular detection are being driven by goals associated with the development of methods that are amenable to miniaturization and automation, and that have high sensitivity and low interference. The new detection methods are confronted by many interfacial issues, which when properly addressed can lead to improved performance. One interfacial property, special wettability, can facilitate precise delivery and local enrichment of molecules to sensing elements. This review summarizes applications of unique features of special wettability in molecular detection including (1) chemical and electrochemical reactions in anchored microdroplets on superwetting surfaces, (2) enrichment of analytes and active materials at low contact areas between droplets and superwetting surfaces, (3) complete opposite affinities of superwetting surfaces toward nonpolar/polar solutes and oil/water phases, and (4) directional droplet transportation on asymmetric superwetting surfaces. The challenges and opportunities that exist in design and applications of special wettability in interfacial delivery and enrichment for detection of a few molecules are also discussed.

Hydrogen (H2) production from alkaline water electrocatalysis is economically appealing yet significantly hindered by the sluggish H2O adsorption and H* binding kinetics on active sites during hydrogen evolution reaction (HER). Herein, we interfacially immobilize Ru clusters on the hierarchical nickel nitride (Ru-Ni3N) nanosheet arrays via the filling of Ru3+ species into the metal vacancies of nickel hydroxide precursors and the subsequent controllab.e nitridation. The optimized Ru-Ni3N shows the outstanding HER performance, affording a 30-fold rise in the intrinsic activity of Ni sites, a outperforming-Pt/C overpotential at ≥125 mA cm-2 while remaining a robust stability. We further establish by a combined study of density functional theory (DFT) calculations with experimental analyses that long-range Ni sites around Ru sites act as active sites via the electron delocalization, remarkably weakening the H2O adsorption and H* binding barriers for enhancing the alkaline HER kinetics. Moreover, it also demonstrates an excellent pH-universal HER and overall water splitting performance. © 2022, The Authors. All rights reserved.

I am fully aware of the critical importance of accuracy in academic publishing and the hard work that goes into the editorial process. I assure you that these errors were unintentional. I kindly ask you to consider the necessary corrections to ensure the integrity of the published work. Below are the specific corrections needed: 1. Author Affiliation Correction: I have noticed that the affiliation of author b needs to be more precisely stated to accurately reflect the research context and origin. The original affiliation was not specific enough, which might cause confusion for readers. Original Text: "School of materials Science and Engineering, Wuhan University of technology, Wuhan 430070, China". Corrected Text: "state key lab.ratory of advanced technology for materials synthesis and processing, Wuhan University of technology, Wuhan 430070, China". I sincerely apologize for any inconvenience this may have caused to the readers and the editorial team. This correction is essential to ensure the accuracy of the article information and to prevent any misunderstandings due to vague affiliation details.2. Correction in the Abstract on Page 1, Line 1: Original Text: "Bismuth telluride, a leading thermoelectric material in the medium-to-low temperature range, is widely used in thermoelectric cooling and power generation". This may mislead readers regarding its application temperature range. In fact, bismuth telluride is primarily an efficient thermoelectric material in the near-room-temperature range. Corrected Text: "Bismuth telluride, a leading near room temperature thermoelectric material, is widely used in thermoelectric cooling and power generation". This change will not affect the overall research content or conclusions but will ensure that the information is presented more accurately. This correction is necessary to enhance the accuracy of the statement. The original description might mislead readers about the specific temperature range where bismuth telluride is m
