Antibiotic residues in water environments have garnered widespread attention. Metal-organic frameworks (MOFs) found extensive applications purification. This study investigates the use of a cobalt-based MOF material, zeolitic imidazolate framework-67(ZIF-67)(Co), for activating persulfate (PMS) to remove residual antibiotic ciprofloxacin (CIP) from aqueous environments. The main findings are as follows: ZIF-67(Co) exhibits insignificant adsorption capacity CIP, and PMS alone does not degrade CIP effectively. However, ZIF-67(Co)-activated demonstrates efficient degradation following pseudo-second-order reaction kinetics. Under optimal conditions catalyst dosage (15 mg) concentration (1.0 mM), removal efficiency reaches 88% after 60 min. Comparative analysis at different initial pH levels shows that highest is reached under mildly acidic conditions, with an 86% rate achieved within min these conditions. Investigation into impact various inorganic anions on ZIF-67(Co)-catalyzed reveals significant inhibition by chloride ions (Cl−), whereas nitrate (NO3-) sulfate (SO42-) minor effects efficiency. system consistent performance across matrices, highlighting ZIF-67(Co)/PMS effective environmental waters. provides technical support residues.

This study used a simple chemical method followed by ultrasonication to make copper sulfide (CuS) nanoparticles and their carbon nanotube-based nanohybrid (CuS-CNTs). To characterize the catalysts, different methods were employed. XRD was confirm that CNTs integrated with crystalline structure, FTIR detect functional groups, SEM-EDX further verified catalysts' shape make-up. The addition of enhanced optical, optoelectronic, electrical properties CuS preventing particle adhesion. UV-Vis, photoluminescence, current-voltage tests showed material could absorb more light, stop charges from combining, move efficiently. Carbon content, moisture absorption, thermal stability evaluated through TGA analysis. had great photocatalytic activity in visible breaking down all MB dye 90 min. In comparison, bare only mineralizes 65.9% 100 reaction rate constant (k) calculated be 0.024 min-1. nanohybrid's shown fact it lost 2.15% its efficiency over five cycles reusability tests. Additionally, this shows nanotechnology composite materials can improve semiconductor photocatalysis, which useful for cleaning up environment.

ABSTRACT The preparation of phase change materials (PCMs) with excellent heat storage capacity, shape stability, and working durability is vital importance for their popularization application. In this work, a series form‐stable PCMs was prepared via blending diglycidyl ether bisphenol A (DGEBA), aliphatic anhydride octadecyl side chains (MNAO), paraffin together followed by thermal curing. Thanks to the plasticizing effect self‐assembly paraffin, crystalline behavior MNAO hardly limited epoxy network, latent EP/Pa‐50 50 wt% content high, up 92.3 J/g. Meanwhile, had low supercooling extent 11.0°C. Instead significant reduction in other properties most after being blended overall performance remained good due strong intermolecular interactions between (based on compatibility) reliable exhibited stability without leakage problem, high (remain stable below 170°C) mechanical (tensile strength 10.5 MPa). This work provides facile strategy prepare PCMs, which have promising application prospects field regulation.

Abstract The rapid development of lithium battery technology is leading to the increasing miniaturization electronic devices, thereby elevating demand for dielectric materials with exceptionally high thermal conductivity and properties. In this study, composites were fabricated by integrating multilayer core‐shell hybrid structure particles into silicone rubber (SR). These created attaching conductive polymer polypyrrole (PPy) silane coupling agent (KH570) onto surface highly thermally ceramic aluminum nitride (AlN). combination PPy KH570 serves enhance interfacial compatibility between AlN SR, concurrently enhancing properties composites. experimental results demonstrated that 50 phr AlN‐PPy‐KH570/SR composite was 0.37 W/(m · K), 1.65 times higher than pure SR (0.23 K)). Additionally, constant increased 4.59, 1.32 (3.48). Moreover, decomposition temperature elevated 475°C. synthesized hold promise widespread use in miniaturized devices operating high‐frequency high‐temperature environments.
