Unveiling Formation Pathways of Ternary I–III–VI CuInS<sub>2</sub> Quantum Dots and Their Effect on Photoelectrochemical Hydrogen Generation Understanding the formation mechanisms of semiconductor nanocrystal quantum dots (QDs) is essential for fine-tuning their optical and electrical properties. Despite their potential in solar energy conversion, the synthesis processes and resulting properties of ternary I-III-VI QDs remain underexplored due to the complex interplay among their constituent elements. Herein, the formation mechanism of ternary I-III-VI CuInS<sub>2</sub> QDs is investigated, and a direct correlation between their synthesis pathways and photoelectrochemical hydrogen generation performance is established. Two distinct formation pathways governed by the Lewis acid strength of the precursors are revealed. Precursors with weaker Lewis acid strength, such as indium acetate-alkylamine complexes, induce the nucleation of Cu <sub>x</sub> S phases, which subsequently transform into CuInS<sub>2</sub> QDs. Conversely, exemplified by indium iodide-alkylamine complexes, precursors with stronger Lewis acid strength enable the simultaneous incorporation of all elements during nucleation, resulting in the direct formation of CuInS<sub>2</sub> QDs. Notably, QDs synthesized through this direct pathway exhibit significantly improved electrical properties with lower electron trap densities, resulting in outstanding photoelectrochemical hydrogen production with an excellent photocurrent density of 11.3 mA cm<sup>-2</sup> at 0.6 V<sub>RHE</sub> when used as sensitizers in photoanodes. These findings highlight the critical role of formation pathways in tailoring the properties of ternary I-III-VI QDs.

Plastic Pores for Switchable and Optimized Adsorption Behaviors Similar to conventional solids, porous materials have demonstrated rigid and flexible behaviors. Here, we show that flexible pores can be not just elastic but also plastic. By variation of the hydrogen-bonding ability and steric hindrance of ligand side groups, the energy difference and barrier between metastable states of a porous framework are fine-tuned to enable the plastic behavior. All metastable pore structures can transform to the target ones in atmospheres of the target guests with sufficiently high pressures, and all shaped pores can remain unchanged after guest removal, resulting in optimized host-guest recognitions for the target guests. Up to a 6-fold increase of adsorption selectivity and 9-fold increase of purification productivity for CO<sub>2</sub> capture and coalmine CH<sub>4</sub> upgrading, and even inversion of CO<sub>2</sub>/C<sub>2</sub>H<sub>2</sub> selectivity, have been achieved by reversible pore-shaping of a single plastic-pore adsorbent. The realization of plastic pores creates an opportunity for on-demand switching of adsorption and separation functions with optimized performances.

Mechanistic study on the photocatalytic degradation of rhodamine B <i>via</i> Mn–Schiff-base-modified Keggin-type polyoxometalate composite materials Organic-inorganic hybrid materials have significant potential in the photocatalytic degradation of Rhodamine B (RhB). In this study, five hybrid materials were successfully synthesized by modifying silicotungstic acid (H<sub>4</sub>SiW<sub>12</sub>O<sub>40</sub>, abbreviated SiW<sub>12</sub>O<sub>40</sub>) with diverse MnL [L = Salen(L<sup>1</sup>), 5-Br-Salen(L<sup>2</sup>), 5-Cl-Salen(L<sup>3</sup>), 3-Me-Salen(L<sup>4</sup>), di-<i>t</i>Bu-Salen(L<sup>5</sup>)] complexes, specifically derivatives featuring various substituents. All the compounds are characterized by IR spectra, elemental analyses and thermogravimetric analyses (TGA). The band gaps of 1.33-1.52 eV and energy bands are obtained through the measurement of UV-Vis DRS and Mott-Schottky. Photocatalytic experiments of (MnL<sup>1</sup>)<sub>4</sub>SiW<sub>12</sub>O<sub>40</sub> (compound 1), (MnL<sup>2</sup>)<sub>4</sub>SiW<sub>12</sub>O<sub>40</sub> (compound 2), (MnL<sup>3</sup>)<sub>4</sub>SiW<sub>12</sub>O<sub>40</sub> (compound 3), (MnL<sup>4</sup>)<sub>4</sub>SiW<sub>12</sub>O<sub>40</sub> (compound 4) and (MnL<sup>5</sup>)<sub>4</sub>SiW<sub>12</sub>O<sub>40</sub> (compound 5) indicate that compound 2 catalyst exhibits the best photocatalytic properties (RhB degrades to 6% during 70 min) while all of them possess catalytic activity for photodegradation of RhB under UV irradiation. Free radical trapping experiments show that the addition of PBQ (·O<sub>2</sub> <sup>-</sup> trapping agents) makes the RhB residual ratio increase from 6% to 60% and indicates that ·O<sub>2</sub> <sup>-</sup> is playing a pivotal role. A possible mechanism of RhB photodegradation in the presence of compound 2 is proposed based on free radical trapping experiments and the energy bands. Future work could focus on fine-tuning the molecular architecture through strategic modification of the organic ligands and precise control of the metal-to-POM ratio, potentially leading to optimized electronic structures and enhanced charge transfer kinetics for superior photocatalytic performance in environmental applications.

Metalations on 2,2′‐bipyridine‐functionalized metal–organic frameworks for catalytic platforms Abstract 2,2′‐Bipyridine (BPY) is a versatile organic ligand, well known for its strong metal‐chelating properties, which make it a crucial component in coordination chemistry. When integrated into metal–organic frameworks (MOFs), BPY significantly enhances the material's properties, particularly in catalysis, due to its ability to coordinate with a wide range of metal ions. This review focuses on the metalation of BPY‐incorporated MOFs (MOF‐BPYs), with an emphasis on the coordination of secondary metal cations at BPY sites. The metals are categorized into first‐, second‐ and third‐row transition metals, and other metals, highlighting key examples such as Pd, Mo, Cu, and Fe. The synergistic interactions between the metal centers and the MOF framework, which contribute to the enhanced catalytic performance of MOF‐BPYs, are explored in detail. The review also addresses mixed‐metal systems, emphasizing their unique properties and applications. Furthermore, strategies for metalation, including the pre‐functionalization of BPY prior to MOF synthesis and post‐synthetic modification, are critically examined. Finally, the stability of parent MOFs—particularly Zr‐based frameworks, known for their robustness—is discussed in relation to the overall performance of MOF‐BPY materials.

Self‐Assembled Hydroxypropyl Celluloses With Structural Colors for Biomedical Applications Hydroxypropyl cellulose (HPC), a cellulose derivative with biocompatibility, edibility, and exceptional solubility in many polar solvents, holds significant potential for biomedical applications. Within a specific concentration range, HPC undergoes self-assembly to form cholesteric liquid crystals, which display distinct structural colors. These colors result from the interaction between incident light and the periodic nano-architecture of HPC, providing long-lasting visual effects that can be dynamically adjusted by factors such as concentration, temperature, and functional additives. This review includes the mechanisms underlying the genesis of structural colors and the regulation of HPCs while summarizing advanced techniques for fabricating HPC-based materials with diverse configurations. Furthermore, through representative examples, we highlight the multifaceted applications of these materials in sensors, bionic skins, drug delivery, and anti-counterfeiting labels. We also propose strategies to address current research and application challenges with the goal of exploring the potential of structural color HPCs for scientific breakthroughs and societal well-being. We hope this review catalyzes HPC-based structural color materials' advancement and future biomedical applications.

Controllable Fabrication of <scp>MnCo<sub>2</sub>O<sub>4</sub></scp>@Polypyrrole@<scp>MXene</scp> Ternary Composites for Electromagnetic Wave Absorption ABSTRACT Nowadays, excessive microwave radiation has become one of the urgent factors affecting human health. To solve the negative effects, electromagnetic wave‐absorbing materials have gradually become indispensable applications. Here, MnCo 2 O 4 @polypyrrole (PPy)@MXene (MPM) ternary composites are successfully synthesized by the combination of hydrothermal synthesis, high‐temperature sintering, in situ polymerization method, and low‐temperature freeze drying. The synergistic effect between dielectric loss and magnetic loss of MnCo 2 O 4 , Ppy, and MXene is studied in detail, showing the prepared composites have excellent absorption properties. MPM‐1 exhibits minimum reflection loss (RL min ) of −62.99 dB at 16.04 GHz under the ultra‐thin thickness (1.21 mm, 50 wt%), and the effective absorption bandwidth (EAB) is 3.94 GHz (13.44–17.38 GHz) at 1.28 mm (50 wt%). The prepared MPM composites have ultra‐thin thickness, wide absorption bandwidth, and excellent microwave absorption properties, which are ascribed to the combination of dielectric loss, magnetic loss, and multiple reflection and scattering effects of core–shell structure. These composites can be used as a significant electromagnetic wave absorbing material, and provide a new research idea for the application of ternary composite materials in electromagnetic wave absorbing materials.

Conventional methods using sutures and gauze often pose constraints in healing effectiveness and cost. Emerging materials, particularly cellulose-based nanofibers, offer a favorable choice due to their biodegradability, biocompatibility, and structural similarity to the extracellular matrix. Cellulose, being an abundant, naturally available biopolymer, forms the basis for modern materials for wound dressing. It is a very resourceful material due to its capability to be processed into films, fibers, and membranes with tailored properties. Surface modification of cellulose membranes with nanoparticles or bioactive compounds assists in enhancing the antimicrobial properties and supports sustained drug release, essential in chronic wound infections. Electrospinning and other modern fabrication techniques allow for controlling the fiber morphology and drug-delivery characteristics. This review highlights the properties, fabrication techniques, surface functionalization, and biomedical applications of cellulose-based materials in wound care. With increasing demand for effective and cost-effective wound treatments, cellulose nanofibers stand out as a sustainable, multifunctional platform for cutting-edge wound dressings, offering improved healing, reduced scarring, and potential for amalgamation with several drug delivery and tissue engineering approaches.

Nano-enhanced Fenton/Fenton-like chemistry: integrating peroxidase nanozymes, MOFs, and MXenes for next-generation colorimetric biosensors Colorimetric biosensors exhibit promising potential toward molecular analysis with a wide range of sample types such as clinical, environmental, animal, and plant samples due to their high portability, sensitivity, specificity, and accuracy. Colorimetric biosensors rely on chromogenic reactions to transduce biochemical signals into visible color changes. Among the various signal transduction mechanisms, the Fenton/Fenton-like reaction is an outstanding reaction that can be used to detect a broad spectrum of analytes under diverse conditions. The ability to detect a wide range of analytes expands the application of the Fenton/Fenton-like reaction; this comes at the cost of specificity. This review highlights how integrating nanomaterials, such as peroxidase nanozymes, metal-organic frameworks (MOFs), and MXenes, can improve conventional Fenton/Fenton-like reactions, significantly enhancing specificity, selectivity, and catalytic efficiency. Besides, we demonstrated that the terms "Fenton/Fenton-like reaction" and "peroxidase-mimic nanozyme activity" fundamentally describe the same catalytic process, providing a unified perspective for researchers in the field. Moreover, the incorporation of MOFs and MXenes offers abundant active sites and enhanced electron transfer, resulting in improved sensitivity and selectivity in Fenton-based colorimetric assays.
