Self-Assembly of Block Copolymers to Prepare Advanced Materials with Hierarchical Functional Nanostructures Block copolymers with diverse compositions and topologies can self-assemble into multi-hierarchical structures, yielding materials with a wide range of functional properties. By adjusting external stimuli such as temperature, solvent polarity, mechanical force, and light exposure, these polymers form various nanostructures—including nanocrystals, micelles, and vesicles in solution; spherical, cylindrical, and lamellar microphases in bulk; and even “fractal” morphologies at interfaces. These hierarchical materials exhibit tailored functionality based on molecular design, enabling broad applications in nanomedicine, electronic devices, optical elements, and catalytic systems. In this review, we first summarize synthetic strategies for block copolymers with varying compositions and architectures. We then discuss their self-assembly behaviors and resulting nanoscale morphologies in bulk, solution, and interfacial environments. Several representative examples of assembled block copolymer systems and their practical applications are highlighted. Finally, we offer perspectives on future developments in the fabrication and application of block copolymer-based nanomaterials. This review provides an overview of strategies and examples for constructing precision nanostructures via block copolymer self-assembly, aiming to inspire further advances in nanomanufacturing technologies.

Interfacial Synthesis of an Electro-Functional 2D Bis(terpyridine)copper(II) Polymer Nanosheet Coordination polymers are attractive materials for various fields of practical application. The high degree of freedom of choice of metal ions and organic ligands plays a critical role in functional diversification. In the present study, we report the liquid-liquid interfacial synthesis of a 2D bis(terpyridine)copper(II) polymer thin film, Cu-tpy. The synthesized Cu-tpy was characterized by various microscopic observations such as TEM, SEM, and AFM, and spectroscopic measurements such as XPS, Raman spectroscopy, SEM/EDS, and UV-Vis spectroscopy. Synchrotron-radiated X-ray scattering confirmed that Cu-tpy was oriented crystalline films. Moreover, Cu-tpy showed electrochemical micro-supercapacitor behavior in the solid-state owing to its ionic nature. This study expands the potential of bis(terpyridine)metal(II) polymers as electro-functional materials.

To detect and monitor these pollutants, gas sensors have become a critical technology. Researchers have developed numerous gas-sensitive materials, among which MXenes-a novel class of two-dimensional materials-have garnered significant attention. Owing to their excellent electron transport properties, abundant surface functional groups, and large specific surface area, MXenes find wide applications in catalysis, sensing, electromagnetic shielding, water treatment, and beyond. However, despite these outstanding properties, MXenes' susceptibility to environmental degradation has hindered their broader development and application as long-term stable gas-sensitive materials. While recent studies have investigated degradation mechanisms and explored various stability enhancement strategies, comprehensive reviews specifically focusing on stability improvements for gas-sensing applications remain scarce. This review first examines the current research on MXene oxidation processes in different environments. Subsequently, it systematically summarizes existing strategies to enhance MXene's long-term stability and its implementation in gas sensing, including optimization of preparation methods, surface protection and modification, composite construction, and other approaches.

Synthesis of acidic–basic Y zeolite from kaolin: catalytic and mechanism study in the cracking of polyethylene Cracking of plastic waste by the acidic FAU-type zeolites faces challenges of low production of light olefins, a high amount of coke formation, and expensive process. Basic zeolites might be a better alternative; however, their preparation is difficult and the related cracking mechanism is unknown. We addressed these difficulties by direct synthesis of a hierarchical acidic-basic FAU-type zeolite (HY-BS) using silica extracted from a low-grade kaolin containing alkaline (earth) metals and investigated the impact of basicity in the linear low density polyethylene (LLDPE) cracking mechanism and products distribution. Compared to an acidic HY zeolite, the HY-BS presented comparable density of Brønsted acidity but a drastically higher density of the basicity. The HY-BS had comparable activity to the reference HY zeolite, but it produced twice light olefins (30.5 <i>vs.</i> 16.2%), triple lighter aromatics (41.0 <i>vs.</i> 13.8%), and less coke in LLDPE cracking. The thermodynamic investigation of thermal and zeolitic cracking of LLDPE was conducted based on the TGA results, along with kinetic analysis using four model-free techniques and a differential method. According to kinetic and thermodynamic parameters and product distribution, the HY-BS exhibited a dual cracking pathway that first followed a carbocation mechanism before switching to a radical mechanism as the reaction progressed, accounting for the reason behind improved light olefins selectivity. Consequently, direct promotion of the basicity of the zeolites synthesized from impure kaolin was effective to overcome difficulties facing plastic waste cracking.

Polyvinylpyrrolidone-Capped CuInS2 Colloidal Quantum Dots: Synthesis, Optical and Structural Assessment Ternary metal chalcogenide quantum dots (QDs), such as CuInS2, have attracted significant attention due to their lower toxicity compared to binary counterparts containing cadmium or lead, making them promising candidates for biomedical imaging and solar energy applications. The surfactant choice is critical for controlling nanocrystal nucleation, growth kinetics, and functionalization. This directly affects the toxicity and applications of QDs. In this work, we report a synthesis protocol for PVP-capped CuInS2 QDs in an aqueous solution. Using density functional theory (DFT) calculations, we predicted the coordination patterns of PVP on the CuInS2 QDs surface, providing insights into the stabilization mechanism. The synthesized QDs were characterized using TEM, XRD, XPS, and FTIR to assess their morphology, chemical composition, and surface chemistry. The QDs exhibited dual photoluminescence (PL) maxima at 550 nm and 680 nm, attributed to defect-related emissions, making them suitable for cell imaging applications. Cytotoxicity studies and cell imaging experiments demonstrate the excellent biocompatibility and effective staining capabilities of the PVP-capped CuInS2 QDs, highlighting their potential as fluorescent probes for long-term, multicolor cell imaging including two-photon microscopy.

Optimization and Mechanistic Insights of Zinc Ascorbate Catalyst for Ring‐Opening Polymerization of Caprolactone Using <scp>RSM</scp> Methodology and <scp>DFT</scp> Calculations ABSTRACT Polycaprolactone (PCL) is an aliphatic polyester recognized for its exceptional versatility and biodegradability, which has garnered significant attention for a wide range of applications. This study presents an innovative methodology for the synthesis of PCL through the ring‐opening polymerization (ROP) of ε‐caprolactone (CL). The approach employs a biocompatible and environmentally benign organometallic zinc ascorbate complex as a catalyst. Derived from ascorbic acid, a well‐established reducing agent, zinc ascorbate serves as a sustainable alternative to conventional tin‐based catalysts, thereby mitigating environmental impact and enhancing safety measures. The catalyst operates effectively under solvent‐free conditions and does not require initiators, achieving a high polymer conversion rate of approximately 79%. The optimization of the reaction parameters was conducted using response surface methodology (RSM) employing a central composite design (CCD). The structural and chemical characterization of the catalyst as well as the resulting polymers was performed using proton nuclear magnetic resonance ( 1 H NMR), Fourier‐transform infrared spectroscopy (FTIR), and x‐ray diffraction (XRD) analyses. Additionally, density functional theory (DFT) calculations elucidated a four‐step coordination‐insertion mechanism for the polymerization of cyclic lactones, with findings supported by Gibbs free energy, electrostatic potential, and non‐covalent interactions. This study underscores the potential of zinc ascorbate as a reliable, nontoxic, and cost‐effective catalyst, fulfilling the increasing demand for sustainable and efficient polymerization processes in commercial and biomedical applications.
