Summary: Nanocomposite anion exchange membranes were prepared based on poly(sulfone trimethylammonium) chloride, with hybrid semi-interpenetrating silica networks containing a large amount of quaternary ammonium groups. The degradation behavior, mechanical properties, and ion conduction activation energy were studied, showing that composite materials prepared using a mixture of precursors exhibited better alkaline resistance and ion exchange capacity.

Summary: The study investigated the removal of methylene blue from aqueous solutions using TiO2 as a catalyst in a photocatalytic process with external UV light. The experimental data showed that adsorption reached equilibrium at 60 minutes and was well fitted by the pseudo-second-order model. The isotherm study indicated that dye uptake by TiO2 is a chemisorption process with a maximum retention capacity of 34.0 mg/g, and the photodegradation of MB was assessed under various experimental conditions.

Summary: The Sol-gel method was used to prepare a Si-Ti-epoxy organic-inorganic hybrid composite sol, which was cured on the carbon steel surface to form a transparent film with excellent electrochemical protection performance and hydrophobicity. The Si-Ti-epoxy hybrid film has a denser structure, higher impedance modulus, and lower corrosion current density compared to a double-thick epoxy film.

Summary: Pollutant treatment is critical in modern society. In this study, hierarchically organized Fe3O4/poly(GMA-EDMA) meso-particles (UPPs) were synthesized and modified with iminodiacetic acid (IDA) to be used as an adsorbent for heavy metal ions. The IDA-modified UPPs showed high adsorption capacities and fast adsorption rates for Cu2+ and Pb2+, and they could also be loaded with beta-FeOOH nano-catalyst for photocatalytic degradation of methylene blue.

Summary: This work focuses on the modification of properties of nanocomposite inorganic-organic films using the nano building blocks (NBBs) approach. Different sols were prepared using acid-catalyzed reactions and various procedures. The size of particles in the sols and the properties of the film surface were observed to be affected by the sol preparation procedure and reaction conditions. The surface morphology of the prepared nanocomposite inorganic-organic films was significantly influenced by the sol preparation procedure.

Summary: In this study, one-dimensional titania-based nanofilaments were synthesized via a hydrothermal method. It was found that regardless of the precursor materials and processing conditions, these nanofilaments served as the essential building blocks in all microstructures. This discovery is of significant importance for understanding and controlling the self-assembly process of nanomaterials.

Summary: The study presents a simple and easy method to stabilize the lactone (L) form of Rhodamine B (RB) on the surface of a polytetrafluoroethylene porous film. The results show that the L-form of RB can be stabilized in the porous film under low polarity environment, and this phenomenon is not observed on polyethylene film and cellulose filter paper. Furthermore, a chemical stability test demonstrates that the equilibrium of RB immobilized on the porous film shifts from the L-form to the zwitterion (Z) form with an increase in environmental humidity.
