Seeds and nanomaterials: seed-assisted synthesis, nanotoxicity, and seed-associated nanotechnology innovations Seeds are the cornerstone of agricultural crop production. They are sources of many valuable materials that can be used to convert bulk materials into nanoforms, thus supporting sustainability in nanomaterial (NM) synthesis and circular farming. The use of seeds in innovative nanotechnology is based on the theoretical knowledge about seed-NM interactions and NM toxicity on seeds. The results show that the internalization of NMs into seeds and their effect on seed physiology depend on several properties of both the NM and the plant species. Nanotechnology innovations including seed-associated strategies for improving abiotic stress tolerance, facilitating pathogen protection, effectively transferring genetic information into embryos, and converting seed oils into biodiesel have been recently developed. This review aims to provide an overview of the current knowledge regarding the complex, multidirectional interactions of seeds with NMs, and suggest directions for future research of seed nanobiology.

Nanoparticle-Based Assays for Antioxidant Capacity Determination Thanks to both endogenous and exogenous antioxidants (AOs), the antioxidant defense system ensures redox homeostasis, which is crucial for protecting the body from oxidative stress and maintaining overall health. The food industry also exploits the antioxidant properties to prevent or delay the oxidation of other molecules during processing and storage. There are many classical methods for assessing antioxidant capacity/activity, which are based on mechanisms such as hydrogen atom transfer (HAT), single electron transfer (SET), electron transfer with proton conjugation (HAT/SET mixed mode assays) or the chelation of selected transition metal ions (e.g., Fe<sup>2+</sup> or Cu<sup>1+</sup>). The antioxidant capacity (AOxC) index value can be expressed in terms of standard AOs (e.g., Trolox or ascorbic acid) equivalents, enabling different products to be compared. However, there is currently no standardized method for measuring AOxC. Nanoparticle sensors offer a new approach to assessing antioxidant status and can be used to analyze environmental samples, plant extracts, foodstuffs, dietary supplements and clinical samples. This review summarizes the available information on nanoparticle sensors as tools for assessing antioxidant status. Particular attention has been paid to nanoparticles (with a size of less than 100 nm), including silver (AgNPs), gold (AuNPs), cerium oxide (CeONPs) and other metal oxide nanoparticles, as well as nanozymes. Nanozymes belong to an advanced class of nanomaterials that mimic natural enzymes due to their catalytic properties and constitute a novel signal transduction strategy in colorimetric and absorption sensors based on the localized surface plasmon resonance (LSPR) band. Other potential AOxC sensors include quantum dots (QDs, <10 nm), which are particularly useful for the sensitive detection of specific antioxidants (e.g., GSH, AA and baicalein) and can achieve very good limits of detection (LOD). QDs and metallic nanoparticles (MNPs) operate on different principles to evaluate AOxC. MNPs rely on optical changes resulting from LSPR, which are monitored as changes in color or absorbance during synthesis, growth or aggregation. QDs, on the other hand, primarily utilize changes in fluorescence. This review aims to demonstrate that, thanks to its simplicity, speed, small sample volumes and relatively inexpensive instrumentation, nanoparticle-based AOxC assessment is a useful alternative to classical approaches and can be tailored to the desired aim and analytes.

Exploring Tailored Fiber Placement in Biocomposite Modular Structures Tailored Fiber Placement (TFP) is an advanced additive manufacturing technology in which fibers are precisely stitched onto a 2D base material to create variable-axial preforms. Sustainable biocomposites are produced by combining natural fibers with polymeric matrices, addressing the growing demand for eco-friendly materials. However, the scalability of this process remains challenging due to the limited stitching areas of TFP machines. This paper discusses the design approach and fabrication of biocomposite gyroid modules, which, through their aggregation, can overcome the limitations of the machines and address a design-for-deconstruction approach. This project demonstrates the potential of a digitally integrated design process using TFP for fabricating lightweight modular biocomposite structures.

Microbial Valorization of Agricultural and Agro-Industrial Waste into Bacterial Cellulose: Innovations for Circular Bioeconomy Integration Agricultural and agro-industrial waste, produced in vast quantities worldwide, presents both environmental and economic challenges. Microbial valorization offers a sustainable solution, with bacterial cellulose (BC) emerging as a high-value product due to its purity, strength, biocompatibility, and biodegradability. This review highlights recent advances in producing BC from agricultural and agro-industrial residues via optimized fermentation processes, including static and agitated cultivation, co-cultivation, stepwise nutrient feeding, and genetic engineering. Diverse wastes such as fruit peels, sugarcane bagasse, cereal straws, and corn stover serve as cost-effective carbon sources, reducing production costs and aligning with circular bioeconomy principles. Advances in strain engineering, synthetic biology, and omics-guided optimization have significantly improved BC yield and functionalization, enabling applications in food packaging, biomedicine, cosmetics, and advanced biocomposites. Process innovations, including tailored pretreatments, adaptive evolution, and specialized bioreactor designs, further enhance scalability and product quality. The integration of BC production into circular bioeconomy models not only diverts biomass from landfills but also replaces petroleum-based materials, contributing to environmental protection and resource efficiency. This review underscores BC's potential as a sustainable biomaterial and identifies research directions for overcoming current bottlenecks in industrial-scale implementation.

To guarantee operational reliability, the thermal conductivity and electrical insulation properties of packaging materials (such as epoxy resin and silicone gel) must align with the demands of high‐performance devices. This review centers on the encapsulation needs of electrical equipment and addresses the inherent conflict between thermal conductivity and dielectric breakdown strength. It systematically examines recent progress in the electrical insulation and heat transfer performance of packaging materials, with a specific emphasis on liquid crystalline epoxy‐based systems. Firstly, the underlying physical mechanisms and associated theoretical models related to thermal conduction and breakdown strength are analyzed. Subsequently, a focused overview of recent advancements in the thermal and electrical properties of liquid crystalline epoxy resins and their composite materials is provided. Finally, current challenges and prospective research directions for liquid crystalline epoxy resins in packaging applications are outlined, along with a discussion of potential hurdles and future opportunities for further development.

Oxidation-Active Radical TTM-DMODPA for Catalysis-Free Hydrogen Peroxide Colorimetric Sensing As a crucial reactive oxygen species, hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) serves as both a physiological regulator and a pathological indicator in human systems. Its urinary concentration has emerged as a valuable biomarker for assessing metabolic disorders and renal function. While conventional colorimetric determination methods predominantly employ enzymatic or nanozyme catalysts, we present an innovative non-catalytic approach utilizing the redox-responsive properties of organic neutral radicals. Specifically, we designed and synthesized a novel radical TTM-DMODPA based on the tris (2,4,6-trichlorophenyl) methyl (TTM) scaffold, which exhibits remarkable optical tunability and oxidative sensitivity. This system enables dual-mode H<sub>2</sub>O<sub>2</sub> quantification: (1) UV-vis spectrophotometry (linear range: 2.5-250 μmol/L, LOD: 1.275 μmol/L) and (2) smartphone-based visual analysis (linear range: 2.5-250 μmol/L, LOD: 3.633 μmol/L), the latter being particularly suitable for point-of-care testing. Validation studies using urine samples demonstrated excellent recovery rates (96-104%), confirming the method's reliability for real-sample applications. Our work establishes a portable, instrument-free platform for urinary H<sub>2</sub>O<sub>2</sub> determination, with significant potential in clinical diagnostics and environmental monitoring.

In situ Electrochemical‐Triggered Dopamine Enzymatic Polymerization for Self‐Revealing and Self‐Erasing Information Storage Hydrogels are emerging as revolutionary information storage media due to their unprecedented responsive and reprogrammable properties. To address the challenge of dynamic information storage without the necessity for external stimuli, electrical writing techniques are adopted for creating dopamine-modified chitosan pattern hydrogel with both self-revealing and self-erasing capabilities, which is realized by modulation the oxidation rate of dopamine spatiotemporally. Specifically, the in situ electrochemical reaction on the surface of electrode initiates the cascade enzymatic canalization of dopamine confining the fast reaction within the writing area, which leads to quick information self-revealing. However, the subsequent air oxidation of dopamine in the unwritten area generally results in self-erasing information. This work pioneers the use of electrical methods to produce hydrogen peroxide on hydrogels, enabling rapid oxidation of dopamine and effective information storage within the hydrogel, which opens new avenues for patterned hydrogels with information storage capabilities.

Improved Insulation Properties of Polypropylene With Highly Orientated Lamellar Induced by NonIsothermal Shear Stress ABSTRACT Polypropylene plays an irreplaceable role in electrical insulation and electrostatic capacitors and has been extensively studied with its microstructure and insulation properties optimised for high‐power density miniaturised devices. The extrinsic modifiers or industrial upgrading have not yet achieved a remarkable breakthrough in either concise theory or comprehensive performance. Here, we develop a nonisothermal shear process on melt to regulate the nucleation density and the lamellar orientation along the surface and reveal pore defects in disorder boundaries between spherulites as the microscopic nature of the property bottleneck. The high‐rated shear process induces a crystallographic surface texture of (1 1 0) planes from which the elimination of micro‐defect benefits. Our high‐rated shear strategy achieves an excellent dielectric strength of 573.7 MV/m with an increase of 33% and an improved insulation resistance by 130% at 100 MV/m with the minimised absorption of injected current.

Decoding the Interplay of Hydrogen Bonding, Dispersion, and Steric Interactions in Conformational Isomerism Among Functionalized Pillar[<i>n</i>]arenes Pillar[n]arenes have garnered popularity due to their unique pillar-shaped structure, which results in hydrophobic cavities. These cavities facilitate the formation of inclusion complexes with guest molecules through non-covalent interactions such as π - π stacking, hydrogen bonding, and van der Waals interactions. Such host-guest interactions enable diverse functionalities in pillar[n]arenes, including molecule recognition, self-assembly, and encapsulation. Nevertheless, it is important to note that the host-guest properties of pillar[n]arenes can be influenced by conformational changes, primarily driven by the rotation of hydroquinone units about their methylene bridge axis. These structural changes can lead to variations in underlying non-covalent and steric interactions, impacting the overall stability of the host-guest system and potentially leading to selective uptake of guest molecules. Additionally, due to relative energy differences, we expect a distribution of pillar[n]arene conformations at thermal equilibrium. In this work, we employ density functional theory (DFT) to evaluate ground state electronic structures of pillar[n]arene conformations across pillar[n]arenes of various sizes and functionalizations. We have aimed to explore the impact of dispersion interactions, hydrogen bonding, and steric interactions on the overall energetics of pillar[n]arene conformations and determine the dominant conformation at 298 K using a Boltzmann-weighted distribution. The relative strengths of hydrogen bonds across various pillar[n]arene conformations have been examined using Bader's QTAIM topological analysis. Furthermore, we have also assessed the solvation of pillar[n]arenes in water using an implicit solvent model that unveils quantitative distinctions in hydrogen bonding and relative dispersion contributions among various pillar[n]arene conformations. Finally, pillar[n]arene conformations with more complex functional groups such as primary amine, alkyl bromide and carboxylic acid, have been studied to evaluate the interplay between underlying interactions such as hydrogen bonding, dispersion, and steric interactions, and their collective impact on the structure and energetics of pillar[n]arene conformations.
