    Article Title: Scalable Fabrication of Semicrystalline Poly(ether ether ketone) Hollow Fiber Nanofiltration Membranes for Efficient Dye/Salt Separation under Harsh Conditions
    Article Snippet: Developing hollow fiber loose nanofiltration membranes (HFMs) that simultaneously achieve high dye/salt separation performance and robust operational stability remains a challenge for textile wastewater treatment under harsh conditions.. Herein, we report a laboratory-adapted kilogram-scale synthesis route for a soluble poly (ether ether ketone) precursor (PEEKI), followed by its conversion into semicrystalline PEEK HFMs via dry-jet wet spinning coupled with an acid-induced crystallization (AIC) strategy.. Furthermore, the effects of PEEKI concentration, PEG-400 content, and air-gap distance on membrane morphology, separation performance, and mechanical properties were systematically investigated.

    Article Title: ROS-responsive hydrogels functionalized with Cu/Zn MOF targeting oxidative stress mitigation and inflammation modulation to promote spinal cord injury repair
    Article Snippet: Crystalline structure was verified by X-ray diffraction (XRD) on a Rigaku D/MAX-2550 V diffractometer (Cu Kα radiation, 40 kV, 40 mA). .. The absorbance and fluorescence emission profiles of the Cu/Zn MOF were recorded on a Hitachi UH4150 UV-Vis-NIR spectrophotometer (Hitachi, Japan) and an Edinburgh Instruments FLS1000 photoluminescence spectrometer (Edinburgh Instruments, UK), respectively, to elucidate its optical characteristics. ..

    Article Title: Full-spectrum CO 2 photoreduction over nickel phytate-modified lead-free perovskite.
    Article Snippet: Biomass-derived nickel phytate(PA-Ni)is immobilized on lead-free Cs2AgBiBr6 (CABB) double perovskite to construct a full-spectrum-responsive photocatalyst for CO2 reduction coupled with water oxidation.. PA-Ni extends light absorption into the near-infrared region through Ni2+ d–d transitions, promotes interfacial electron transfer, and provides Ni active sites for CO2 adsorption and activation, thereby enabling efficient and selective CO evolution..

    Article Title: Highly efficient and recyclable pyridinium-based poly(ionic liquid)s for selective gold recovery from electronic waste
    Article Snippet: A series of pyridiniumand quaternary ammonium-based poly(ionic liquid)s (PILs) with chloride (Cl ) or bromide (Br ) counter-anions were synthesized and evaluated for the adsorption of AuCl4 from aqueous solutions.. The adsorption kinetics followed the pseudo-second-order model, and equilibrium data were well described by the Langmuir isotherm, indicating monolayer chemisorption.. Pyridinium-based PILs exhibited significantly higher gold uptake than their quaternary ammonium analogues, attributable to the synergistic contribution of anion–π interactions, and C–H⋅⋅⋅Cl hydrogen bonding.

    Article Title: Low-temperature synthesis of LaB6 powder from oxides driven by Na2SiO3 formation
    Article Snippet: Lanthanum hexaboride (LaB6) is a functional material with excellent thermionic emission and near-infrared (NIR) absorption properties but has typically required the use of temperatures exceeding 1400 C during synthesis.. The present study demonstrates the low-temperature synthesis of LaB6 powder using a novel method taking advantage of the thermodynamic driving force associated with sodium silicate (Na2SiO3) formation.. LaB6 powder was obtained by heating compacts of La2O3, B2O3, and SiO2 powders with Na metal at 600–1100 C under an argon atmosphere.

    Article Title: A novel polyurethane phase change material with intrinsically hydrophobicity and flexibility for personal thermal management in outdoor high-temperature environments
    Article Snippet: Frequent summer hot weather has accelerated the demand for high-performance cooling garments.. However, radiative cooling alone is insufficient to alleviate heat stress under strong solar irradiation and elevated ambient temperatures, highlighting the need for enhanced cooling capabilities.. Here, phase change cooling integrates with radiative cooling to develop an intrinsically hydrophobic and flexible polyurethane-based phase change material (PXHE-H).

    Article Title: A materials-science perspective on the “Purple Ding” question: Evidence from iron-rich glazes at the Lanxi kiln, China
    Article Snippet: The existence and nature of “Purple Ding” ware remain unresolved questions in Chinese ceramic archaeology.. The recent discovery of visually purple iron-rich glazes at the Lanxi kiln provides a new comparative case for exploring how such a glaze appearance could be achieved within Song-period ceramic technology.. This paper presents a systematic scientific and technological analysis of iron-rich glazes excavated from the Lanxi kiln in Fujian, China, dating to the Southern Song Dynasty.
