Summary: Researchers have developed novel antifouling LNMs by codeposition of AMTHBA and PDA on PSf. The loose selective layers of the LNMs can be improved by introducing hydrophilic and antimicrobial AMTHBA, resulting in enhanced permeability and antifouling capacities. The optimized PSf/PDA-AM 1.5 LNM achieved high water permeance, excellent dye rejection, and low salt retention, as well as outstanding antifouling properties and sterilization efficacy.

Summary: This study focuses on the development of hybrid ultrafiltration membranes using Poly(vinylidene fluoride) (PVDF) with zeolitic imidazolate framework-8 (ZIF-8) nanocrystals. The study investigates the surface morphology and distribution of ZIF-8 in the PVDF matrix, as well as its antibacterial activity and chemical functionality. The addition of ZIF-8 enhances the hydrophilicity and porosity of the membranes, resulting in increased pure water permeability and improved rejection and permeate flux for bovine serum albumin (BSA) and humic acid (HA). The PVDF hybrid membrane with 2 wt% of ZIF-8 demonstrates excellent permeability, antifouling, and antibiofouling abilities, making it a promising choice for water treatment applications.

Summary: This paper investigates the cooperating mode selection problem of a manufacturer selling products through offline and online channels. The study finds that demand disruptions and cross-channel effects significantly influence the manufacturer's optimal operational decisions and platform mode selection. The presence of demand disruptions complicates the manufacturer's mode selection, and higher cross-channel effects can lead to increased production. Furthermore, demand disruptions have a significant impact on the profits of both the manufacturer and the platform.

Summary: A novel fluorescent probe L, composed of beta-Cyclodextrin (beta-CD) and thiosemicarbazide moieties, was designed for the detection of copper ions. The fluorescence of probe L was significantly quenched in the presence of Cu2+ in Tris-HCl (pH = 7.4) solution, while other interfering ions had no effect. The probe L formed a 1:1 complex with Cu2+ and the detection limit was calculated to be 1.37 µM. These results indicate that probe L may offer a convenient method for visual detection of Cu2+ in environmental and biological systems.

Summary: In this study, a simple green preparation method was designed to synthesize polymer-derived N,O-doped bowl-like hollow carbon microspheres (BHCMs) for enhanced electromagnetic wave absorption performance. BHCMs were fabricated using copolymerized microspheres of allyl methacrylate and acrylonitrile (P(AMA-AN)) synthesized through soap-free emulsion polymerization as a template and polydextrose as the carbon source. The unique structure of BHCMs-2 provides excellent electromagnetic wave attenuation and impedance-matching characteristics. The study proposes a new and green preparation method for carbon materials to improve their absorption properties.

Summary: This study used grand canonical density functional theory (GC-DFT) and CANDLE continuum solvation model to accurately simulate the performance of Cobalt-doped phthalocyanine monolayer (Co-Pc) catalyst in electrochemical CO2 reduction. The calculation results were in excellent agreement with experimental values, explaining the competition between CO2 activation and hydrogen evolution reaction and predicting the potential determined step and onset potential. The study also revealed the potential-dependent competition between physical and chemical adsorption of CO2 and H formation, as well as the reason for high selectivity of CO2 reduction at a specific potential range.

Summary: This paper presents a fiber end-face integrated lithium niobate (LN) crystal probe with a reflective design. The probe utilizes the pyroelectric and thermo-optic effects of LN to achieve a steep temperature response in a narrow range, which is ideal for temperature measurement applications. By mapping the ambient temperature to the output light using the polarization state modulation (PSM) method, the sensitivity of the probe reaches 5.37 K-1cm-1, 447 times higher than that of a polarization-maintaining fiber (PMF). The compact size and efficient light transmission make the probe suitable for various applications, including measuring core temperature and remote monitoring in the biological and industrial fields.
