Recent advances in nanoparticle-modified zeolites: functionalization strategies and diverse applications Nanoparticle-modified zeolites (NPZs) are multipurpose materials that combine the special functions of nanoparticles with the structural benefits of zeolites. They present a variety of applications in energy, environmental remediation, adsorption, and catalysis. Surface area, porosity, ion-exchange capacity, stability, and other physicochemical properties are enhanced by structural alterations and nanoparticle incorporation, as highlighted in this review of recent developments in the design, synthesis, and use of NPZs. Because pore size, Si/Al ratio, framework type, and natural or synthetic origin all have a significant impact on performance, special attention is paid to how zeolites are classified. Rather than offering an exhaustive survey, the review highlights representative and application-relevant examples that demonstrate how rational nanoparticle incorporation significantly enhances adsorption capacity, catalytic activity, and selectivity. Key application domains-including CO<sub>2</sub> capture, pollutant removal, catalytic conversions, hydrogen production, and selected biomedical uses-are discussed to illustrate the multifunctionality of NPZs while maintaining a clear thematic focus on performance enhancement mechanisms. Current challenges, such as nanoparticle leaching, diffusion limitations, high synthesis cost, and scalability constraints, are critically assessed. Emerging strategies to address these issues, including hierarchical zeolite structuring, green and template-free synthesis approaches, and hybrid nanocomposite engineering, are also examined. In addition, a concise techno-economic perspective is presented to evaluate the feasibility of large-scale implementation and industrial translation. By integrating fundamental structural insights with application-driven considerations, this review clarifies key design principles and outlines future research directions for the sustainable development and commercialization of nanoparticle-modified zeolites.

Functionalized Metal–Organic Frameworks Integrated with Plasmonic Nanoparticles: From Synthesis to Applications Plasmonic nanoparticles (NPs) exhibit exceptional optical and electromagnetic (EM) properties that are, however, confined to their near-field region, limiting effective interactions with non-adsorbed species. Metal-organic frameworks (MOFs), renowned for their high surface area and tunable pores, provide an ideal complement through surface enrichment and subsequent molecular enrichment within their pores. The integration of plasmonic NPs with MOFs into nanohybrids overcomes this spatial constraint. This architectural synergy creates a synergistic effect, yielding properties superior to either component alone. This review summarizes recent advances in NP-MOF nanohybrids, with a focus on synthesis strategies for diverse architectures and their emergent functionalities. We highlight how this synergistic effect enables breakthrough applications in chemical sensing, cancer therapy, and catalysis. Finally, we conclude our discussion and present a critical outlook that explores the challenges and future opportunities in the design and applications of NP-MOF nanohybrids.

Microwave-Assisted One-Pot Synthesis of Medium-Entropy Oxides for Dual-Mode Electrochemical and Colorimetric Analysis of Sweat Biomarkers Enzyme-mimicking nanomaterials (nanozymes) promise robust alternatives to biological catalysts for continuous health monitoring, yet achieving sufficient catalytic activity remains challenging. Here, multimetallic medium-entropy oxide (MEO) nanoparticles incorporating five transition metals (Fe, Co, Mn, Ni, Cu) demonstrate exceptional dual-mode biosensing capabilities. A facile, one-pot microwave-assisted synthesis process yields nanoparticles (12 nm diameter, configurational entropy of 1.41 R) with abundant oxygen vacancies and mixed-valence states that serve as highly active catalytic centers. When integrated with graphene oxide, the MEO creates a robust platform for nonenzymatic electrochemical detection of the stress hormone cortisol, achieving a low limit of detection (LOD) of 1.9 nM and a high sensitivity of 46.5 ± 1.9 μA μM<sup>-1</sup> cm<sup>-2</sup>. The material also exhibits powerful peroxidase-like activity, enabling dual-mode colorimetric sensing. This system provides a "signal-on" response for hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) detection with a LOD of 2.2 μM and a selective "signal-off" response for glutathione (GSH) quantification (LOD: 0.01 μM) through an inhibitory binding mechanism. Mechanistic studies establish that the versatile catalytic performance originates from the synergistic interplay between M(II)/M(III) redox cycling, superoxide radical generation at oxygen vacancies, and efficient electron transfer. The entropy-stabilized structure maintains 92% of its activity over 20 days without refrigeration. These findings establish multimetallic entropy engineering as a powerful strategy for creating stable, high-performance nanozymes suitable for wearable biosensors and point-of-care diagnostics.

sp‐Hybridized Carbon Modulates the Spin States of Ir Nanozyme for Efficient Oxygen Activation The kinetics of oxidase-like (OXD-like) nanozymes are significantly influenced by the electronic configuration of their active sites. In this study, a nanozyme that features unique electronic interactions was created by in situ construction of iridium nanoparticles on graphdiyne-coated carbon nanotube (Ir/GDY/CNT). This configuration enables efficient and specific oxygen activation through a spin-state modulation mechanism. The incorporation of sp-hybridized carbon (sp-C) facilitates a transition in the electronic structure of the Ir sites from low-spin to high-spin states via electronic metal-support interactions. This enhances the adsorption strength and electron transfer between the Ir sites and reactants/intermediates, leading to an improved OXD-like activity. The Ir/GDY/CNT nanozyme demonstrates a 6.2-fold enhancement in OXD-like activity compared to pristine iridium nanoparticles, and a 2.5-fold improvement over Ir/CNT. Capitalizing on this improved catalytic performance, a colorimetric sensor was developed for the detection of organophosphorus pesticides. The sensor exhibits a wide linear range (0.1-1200 ng mL<sup>-1</sup>) and ultralow detection limit (0.03 ng mL<sup>-1</sup>), outperforming previously reported systems. This work establishes a generalizable strategy for developing high-performance OXD-like nanozymes through spintronics-level engineering, which presents significant potential for environmental and diagnostic applications.

Emphasis on the importance of Ga-doped ZnO thin film gas sensors fabricated by the SILAR approach for ammonia detection Abstract This study highlights the importance of ZnO-based thin film sensors in gas-sensing applications and examines the impact of gallium concentration on their ability to detect ammonia. Ga-doped ZnO thin films were fabricated using the successive ionic layer adsorption and reaction (SILAR) method with varying doping concentrations. A series of samples was prepared, ranging from pure ZnO to films doped with 2%, 4%, 6%, and 8% Ga. The structural, morphological, and optical characteristics of the synthesized ZnO sensors were examined using various physical and chemical characterization techniques. XRD analysis confirmed that increasing the Ga doping concentration enhanced the degree of crystallization within the ZnO lattice. As the lattice parameter c increased, a corresponding decrease in the (002) diffraction intensity was observed, accompanied by a slight shift of the diffraction peaks toward lower angles. SEM observations revealed that the incorporation of Ga significantly influenced both the size and morphology of the ZnO nanostructures, likely due to its role in nucleation and crystal growth processes. Notably, a morphological transition from nanoflower-like structures to hexagonal nanodiscs was detected as the Ga doping concentration increased. Raman spectroscopy further verified the successful incorporation of Ga ions into the ZnO lattice through the observed shifts in the E 2 (high) phonon mode. The phonon mode at 439 cm⁻1, characteristic of pure ZnO, exhibited a redshift with increasing Ga content. FTIR spectra displayed distinct peaks in the low-wavenumber region (400–800 cm⁻1), corresponding to Ga–O and Zn–O vibrations, indicative of metal–oxygen bonding. With increasing Ga incorporation, minor variations in peak intensity and position were observed, confirming the substitution of Zn atoms by Ga within the lattice. Gas sensing measurements demonstrated that the fabricated films exhibited high sensitivity toward ammonia (NH 3 ) gas at room temperature. The improved response was attributed to both the morphological evolution and the electronic contribution of Ga dopants. Notably, the 6GZO sensor achieved a maximum response of 198% to 100 ppm NH 3 at 25 °C, along with fast response and recovery times of 7 and 8 s, respectively, and excellent selectivity compared to other target gases.

Unraveling the physical genome of biochar Biochar, a porous carbonaceous material produced through the thermochemical conversion of biomass, is garnering significant attention for its critical roles in carbon sequestration, sustainable energy solutions, and advanced materials engineering. The strategic and precise manipulation of its intrinsic physical properties—such as hierarchical porosity, mechanical robustness, thermal conductivity, electrical transport behavior, and tunable optical response—has now emerged as a fundamental enabler for designing next-generation multifunctional carbon systems. This review provides a comprehensive, integrated, and multiscale examination of these physical characteristics, with a particular focus on elucidating the complex, often synergistic relationships among them. By establishing robust correlations spanning from the atomic-level molecular structure and chemical functionality to the microstructural morphology and ultimately the macroscopic performance, a coherent structure-property-function framework is constructed. This framework is essential for guiding the rational design of biochar-based materials. Furthermore, persistent knowledge gaps and the challenges posed by these gaps are critically highlighted. Finally, future pathways toward precision-engineered biochar for high-value applications in energy storage, photothermal conversion, environmental remediation, and beyond are proposed.

Hierarchical transfer learning: an agile and equitable strategy for machine-learning interatomic models Machine-learned interatomic models are growing in popularity due to their ability to afford near quantum-accurate predictions for complex phenomena with orders-of-magnitude greater computational efficiency. However, these models struggle when applied to systems of many element types due to the approximately exponential increase in number of parameters that must be determined. To mitigate this challenge, we present a new hierarchical transfer learning approach that allows the fitting problem to be decomposed into smaller independent and reusable parameter blocks that enable development of explicitly chemically extensible ML-IAM. Application of this strategy is demonstrated for C and N mixtures under conditions ranging from nominally ambient to ~10,000 K and 200 GPa for compositions from 0 to 100% N. Ultimately, this strategy makes model generation for chemically complex systems more tractable and efficient, facilitates comprehensive model validation, and makes ML-IAM development for problems of this nature more accessible to users with limited access to extreme computing infrastructure.

Advancing Bioconjugated Quantum Dots with Click Chemistry and Artificial Intelligence to Image and Treat Glioblastoma Glioblastoma (GB) is one of the most aggressive and invasive cancers. Current treatment protocols for GB include surgical resection, radiotherapy, and chemotherapy with temozolomide. However, despite these treatments, physicians still struggle to effectively image, diagnose, and treat GB. As such, patients frequently experience recurrence of GB, demanding innovative strategies for early detection and effective therapy. Bioconjugated quantum dots (QDs) have emerged as powerful nanoplatforms for precision imaging and targeted drug delivery due to their unique optical properties, tunable size, and surface versatility. Due to their extremely small size, QDs can cross the blood-brain barrier and be used for precision imaging of GB. This review explores the integration of QDs with click chemistry for robust bioconjugation, focusing on artificial intelligence (AI) to advance GB therapy, mechanistic insights into cellular uptake and signaling, and strategies for mitigating toxicity. Click chemistry enables site-specific and stable conjugation of targeting ligands, peptides, and therapeutic agents to QDs, enhancing selectivity and functionalization. Algorithms driven by AI may facilitate predictive modeling, image reconstruction, and personalized treatment planning, optimizing QD design and therapeutic outcomes. We discuss molecular mechanisms underlying interactions of QDs with GB, including receptor-mediated endocytosis and intracellular trafficking, which influence biodistribution and therapeutic efficacy. Use of QDs in photodynamic therapy, which uses reactive oxygen species to induce apoptotic cell death in GB cells, is an innovative therapy that is covered in this review. Finally, this review addresses concerns associated with the toxicity of metal-based QDs and highlights how QDs can be coupled with AI to develop new methods for precision imaging for detecting and treating GB for induction of apoptosis. By converging nanotechnology and computational intelligence, bioconjugated QDs represent a transformative platform for paving a safer path to smarter and more effective clinical interventions of GB.
