In-situ restructuring of Ni-based metal organic frameworks for photocatalytic CO2 hydrogenation As the global quest for sustainable energy keeps rising, exploring novel efficient and practical photocatalysts remains a research and industrial urge. Particularly, metal organic frameworks were proven to contribute to various stages of the carbon cycle, from CO<sub>2</sub> capture to its conversion. Herein, we report the photo-methanation activity of three isostructural, nickel-based metal organic frameworks incorporating additional niobium, iron, and aluminum sites, having demonstrated exceptional CO<sub>2</sub> capture abilities from thin air in previous reports. The niobium version exhibits the highest performance, with a CO<sub>2</sub> to CH<sub>4</sub> conversion rate in the order of 750-7500 µmol*g<sub>catalyst</sub><sup>-1</sup>*h<sup>-1</sup> between 180 °C and 240 °C, achieving 97% selectivity under light irradiation and atmospheric pressure. The in-depth characterization of this framework before and after catalysis reveals the occurrence of an in-situ restructuring process, whereas active surface species are formed under photocatalytic conditions, thus providing comprehensive structure-performance correlations for the development of efficient CO<sub>2</sub> conversion photocatalysts.

MOF-based nanocomposites in polymer matrix: progress and prospects Metal–organic frameworks (MOFs), an emerging class of crystalline microporous functional fillers, have garnered significant attention in materials science owing to their tunable pore architecture and abundant coordinatively unsaturated sites. However, MOF materials encounter substantial challenges in practical applications, including poor spatial dispersion, severe agglomeration, and insufficient interfacial compatibility with polymer matrix, which substantially impede their incorporation into polymer composite materials. Building upon the foundational research of our group in MOF surface modification and nanocomposite engineering, this work systematically investigates the hierarchical integration strategies of MOFs with dimensionally controlled nanomaterials (encompassing 0D nanoparticles, 1D nanofibers/nanotubes, 2D nanosheets, and 3D interconnected networks). Through precise modulation of interfacial chemistry and architectural design, we have successfully addressed the dispersion limitations of MOFs and significantly enhanced the synergistic effects within the composite matrix. Experimental results demonstrate that this novel integration approach effectively mitigates nanofiller aggregation and substantially enhances the flame retardancy, mechanical strength, and electrical conductivity of the resultant composites. A detailed examination has been conducted exploring how MOF-based nanocomposites integrate within the polymer matrix, encompassing fabrication approaches, physical and chemical properties, and prospective uses. Our investigation addresses existing obstacles while evaluating future directions within this expanding research domain. By offering both fundamental scientific understanding and concrete recommendations, this work aims to facilitate advances in developing advanced functional materials incorporating MOF-based nanomaterials. The findings presented serve as a foundation for researchers working toward innovative composite systems with enhanced capabilities and performance metrics.

Biosynthesized metallic nanoparticles for sustainable environmental remediation: mechanisms, applications, and future perspectives Increasing environmental pollution crisis due to toxic pollutants such as heavy metals, synthetic dyes, and hazardous waste necessitates the urgent establishment of environmentally benign and sustainable remediation technologies. This review summarizes recent advances in the biosynthesis of metallic nanoparticles (BMNPs) application of green pathways involving biological agents such as plants, bacteria, fungi, and enzymes. These biogenic nanoparticles have superior physicochemical characteristics such as high surface area, stability, reactivity, and catalytic activity, making them extremely effective in contaminant degradation, adsorption, and sequestration. We elucidate the basic principles and mechanisms of biosynthesis, emphasising the contributions of varied biological agents towards metal ion reduction and stabilization into nanoparticles. Further their applications in controlling environmental pollution, such as removal of heavy metals (mercury ions, Hg2⁺), degradation of dyes (methylene blue), and decontamination of toxic gases (nitrogen oxides, NOₓ) has been illustrated in detail. Additionally, critical analysis of the environmental fate, ecotoxicity, and regulatory issues of biogenic nanoparticles, as well as toxicity assessment methods has been carried out. It also highlights the recent development on nanoparticle functionalization and nanocomposite synthesis to extend their reactivity and stability. Despite promising outcomes, challenges such as scalability, control over nanoparticle properties, variability in biological sources and the need for a complete understanding of ecotoxicological behaviour still remains unresolved. To address this gap, integrating biosynthesis with advanced engineering tools and real-time monitoring technologies becomes very crucial. Such integration pivots on the incorporation of green nanotechnology into conventional remediation techniques. It further emphasizes the necessity of regulatory framework, standardized protocol, and interdisciplinary collaboration to facilitate the transition of these green nanomaterials from laboratory to widespread field application. Such a holistic approach offers sustainable solution to address global environmental challenges and achieving effective environmental restoration and pollution management.

A pseudo-cubic metal–organic cage with conformationally switchable faces for dynamically adaptive guest encapsulation The creation of hosts capable of accommodating different guest molecules may enable these hosts to play useful roles in chemical purifications, among other applications. Metal-organic cages are excellent hosts for various guests, but they generally incorporate rigid structural units that hinder dynamic adaptation to specific guests. Here we report a conformationally adaptable pseudo-cubic cage that can dynamically increase its cavity volume to fit guests with differing sizes. This pseudo-cube incorporates a tetramine subcomponent with 2,6-naphthalene arms that cooperatively adopt a non-planar conformation, enabling the cage faces to switch between endo and exo states. A wide range of guest molecules were observed to bind within the cavity of this cage, spanning a range of sizes from 46% to 154% of the cavity volume of the empty cage. Experimental and computational evidence characterizes the flipping of cage faces from endo to exo, expanding the cavity upon binding of larger guests.

Nanoscience in Action: Unveiling Emerging Trends in Materials and Applications Since their inception in the early 1960s, the use of nanoscale materials has progressed in leaps and bounds, and their role in diverse fields ranging from human health to energy is undeniable. In this report, we utilize the CAS Content Collection, a vast repository of scientific information extracted from journals and patent publications, to identify emerging topics in this field. This involves understanding trends, such as the growth of certain topics over time, as well as establishing relationships among emerging topics. We achieved this by using a host of strategies including a quantitative natural language processing (NLP) approach to identify over 270 emerging topics and subtopics across three major categories-materials, applications, and properties-by surveying over 3 million documents spanning across two decades in the nanoscience landscape. This wealth of information has been condensed into several conceptual Trendscape maps and other data visualizations, providing metrics related to the growth of identified emerging concepts, and grouped into hierarchical classes, and the connections between them have been explored. Our extensive analysis taking advantage of an NLP-based approach along with robust CAS indexing provides valuable insights in the field that we hope can help to inform and drive future research efforts. In a series of interconnected papers, we will present our findings from this project, with a focus on four major applications of nanoscale materials-drug delivery, sensors, energy, and catalysis-to provide a more comprehensive and detailed picture of the use of nanotechnology in these fields.

Hollow engineering of core–shell Fe3O4@MoS2 microspheres with controllable interior toward optimized electromagnetic attenuation The development of electromagnetic wave absorbing materials with wideband absorption and thin thickness confronts huge challenges in addressing the aggravating problem of electromagnetic pollution. Herein, hollow core–shell Fe3O4@MoS2 microspheres with controllable interior and tunable shell are constructed to precisely regulate the electromagnetic wave attenuation. The results demonstrate that hollow Fe3O4 microspheres exhibit strong absorption in C–X bands owing to their strong ferromagnetic resonance. By structural regulation, hollow core–shell Fe3O4@MoS2 microspheres not only ensure superior electromagnetic wave absorption intensity at thin thickness, but also endow wideband absorption. Benefiting from the cooperative merits of manipulated Fe3O4 interior and controllable MoS2 shells, the as-synthesized microspheres display obvious interface polarization, defect/dipole polarization, and multiple scatterings, thereby resulting in ameliorated impedance matching and outstanding attenuation performance. Especially for Fe3O4@MoS2-2, the minimum reflection loss is − 69.01 dB at 2.66 mm and the effective absorption bandwidth reaches 8.40 GHz when the thickness is 3.0 mm. This study systematically investigates the balance relationships between core–shell structures and absorption attenuation, and simultaneously provides a referable strategy to modulate the electromagnetic wave absorption by structural optimization.

All‐Dielectric Ultra‐Broadband Microwave Absorbing Aerogel with Optimized Dielectric Dispersion via Dielectric Relaxation Time Regulation The limited conceptual understanding and lack of effective techniques for optimizing dielectric dispersion continue to hinder the development of all-dielectric broadband microwave-absorbing materials (MAMs) with minimal thickness. In this study, a strong theoretical correlation between dielectric relaxation time and dielectric dispersion behavior is established by applying the ideal dielectric dispersion law in conjunction with Debye theory. This led to a strategic approach aimed at extending the relaxation time to optimize dielectric dispersion and achieve broadband microwave absorption without incorporating magnetic components. To realize this, fluorinated graphene (FG) is engineered to stack with MXene nanosheets, resulting in the fabrication of MXene/fluorinated graphene/cellulose nanofibers (MXene/FG/CNFs) aerogels. This configuration significantly extended the dielectric relaxation time of interfacial dipoles from 9.2 ps in MXene/CNFs to 19.5 ps in MXene/FG/CNFs aerogels, corresponding to a fluorine content of 35% in FG. This extension is attributed to increased interfacial dipole moments from strong electronic delocalization induced by highly electronegatively fluorine atoms. The improved structure yield progressively optimized dielectric dispersion, resulting in a maximum effective absorption bandwidth (EAB<sub>max</sub>) of 9.08 GHz at a thickness of 2.54 mm and a low density of 34.4 mg cm<sup>-3</sup>. Moreover, the hybrid aerogel also exhibited fascinating Joule heating, thermal insulation, and compressive strength.
