High-sensitivity piezoelectric response enabled by heterogeneous stress–electric field distribution in 3D interconnected porous ceramics Porous piezoceramics are attractive for high-sensitivity sensing and energy conversion due to their low density, reduced dielectric constant (<em>ε</em><sub>r</sub>), and good mechanical compliance. However, increasing porosity is often accompanied by a significant reduction in the piezoelectric charge coefficient (<em>d</em><sub>33</sub>), creating an intrinsic trade-off that limits the practical use of porous structures in high-sensitivity piezoelectric devices and leaves their overall performance advantages under debate. In this work, we overcome this challenge by developing a fully open-cell, three-dimensionally interconnected PZT-PZN-PNN porous piezoceramic (3D-PPC). Despite an ultrahigh porosity of 92%, the material maintains a high <em>d</em><sub>33</sub> of ~470 pC N⁻¹, about 90% of that of the dense ceramic. While its effective <em>ε</em><sub>r</sub> is reduced to ~140 (a 94% decrease), leading to an approximately 14-fold enhancement in the piezoelectric voltage constant <em>g</em><sub>33</sub> (~380 × 10<sup>-3</sup> Vm/N). Combined microstructural characterization, domain analysis, defect studies, and multiphysics simulations show that the exceptional performance arises from synergistic effects of heterogeneous stress and electric fields, multiscale domain structures, and defect-mediated regulation within the three-dimensionally interconnected porous architecture. Finally, the material generates peak output voltages up to 200 V under subtle mechanical excitation and achieves an ultrahigh sensitivity of 38.7 V/kPa. These results show that three-dimensionally interconnected porous architectures are not merely passive means of reducing dielectric permittivity, but active structural strategies for tuning local fields and polarization behavior.

Advancements in post-harvest techniques for preserving fresh produce: a comprehensive review One of the biggest constraints in the food industry is the economic transportation of healthy food products with reduced post-harvest losses. Edible coatings are bio-based films applied to fruits and vegetables to enhance their shelf life during post-harvest storage and distribution. This review critically evaluates recent advances in edible coating and packaging technologies for post-harvest preservation of fruits and vegetables. Food packaging designed from nature's building blocks, such as sugars, amino acids, and fats, has long reflected exemplary success in maintaining the freshness and quality of fresh foods. The literature is categorised into polysaccharide, protein, lipid-based, and composite edible coatings, as well as active and intelligent packaging systems. Emerging technologies, especially 3D printing, hold great promise for developing unprecedented surface topography and tailored features, enabling the controlled addition of beneficial compounds. In contrast, food packaging is a functional barrier, offering essential protection against environmental assailants such as UV light, oxygen, microbial penetration, and water vapor. Freshness-retaining packaging technologies employ agents such as antioxidants, charcoal for gas management, and moisture managers, which play a valuable role in preserving the quality and nutritional content. Across the reviewed studies, these systems demonstrated shelf-life extensions ranging from several days to multiple weeks, along with reduced weight loss, delayed microbial spoilage, and improved physicochemical quality. Further, the growing use of intelligent packaging with sensors and freshness indicators enables real-time quality and safety inspections along the supply chain. Despite these advancements, challenges remain regarding large-scale applicability, cost-effectiveness, sensory acceptance, and regulatory standardisation. This study concludes that a sensible, well-designed blend of tailored food wraps and advanced storage protocols forms a strong alliance with high potential to jointly provide robust protection, conserve nutrients, and substantially prolong the freshness of a variety of fresh produce.

Effect of Different Magnetite Nanoparticle Coatings on Blood Circulation, Biodistribution, Tumor Accumulation and Penetration <b>Background/Objectives:</b> Magnetite nanoparticles represent promising candidates for a broad spectrum of biomedical applications, ranging from in vitro diagnostic assays to in vivo imaging, hyperthermia, and targeted drug and gene delivery, with some nanoagents already approved for clinical use. A critical determinant of their functionality is the nanoparticle coating, which facilitates beneficial interactions within biological systems. In the context of tumor-targeted therapeutic delivery, key design parameters-particularly surface coatings-can be optimized to enhance treatment efficacy by modulating blood circulation kinetics, biodistribution, and other critical properties. However, current preclinical screening methods primarily rely on cell culture models to identify potential nanocarriers, yet these systems often poorly correlate with actual in vivo performance. This discrepancy highlights the necessity of incorporating more biologically relevant testing platforms, such as high-throughput in vivo assays. <b>Methods:</b> In this work, we employed an original magnetic particle quantification (MPQ) technology to systematically evaluate the blood circulation kinetics and biodistribution patterns for magnetite nanoparticles with 17 different coatings across multiple organs and tissues, including the liver, spleen, lungs, kidneys, heart, tumor, brain, peripheral blood, muscle, and bone. This methodology offers high sensitivity, user-friendly operation, and provides quantitative measurements across a broad dynamic range of nanoparticle concentrations. These advantages enabled high-throughput acquisition of precise blood circulation and biodistribution data. In addition, histological analysis was conducted to evaluate nanoparticle penetration depth within tumor tissue. <b>Results:</b> Here we conducted a comprehensive study of the effect of 17 different polymer-, lectin-, and small molecule-based coatings on the behavior of magnetite nanoparticles in vivo. For each type of obtained nanoparticles, we implemented passive targeting as well as magnetic targeting, the latter using an external magnetic field localized in the tumor area. <b>Conclusions:</b> The collected dataset provides critical insights into how surface modifications influence nanoparticle performance in complex biological systems, offering valuable guidance for optimizing therapeutic nanocarrier design.

Wearable Inorganic Yarn Thermoelectric Generator Based on Solution-Processed Silver Selenide Abstract Thermoelectric generators (TEGs) are a promising strategy for harvesting body heat to power wearable electronics. However, the development of a TEG that combines high mechanical durability, effective utilization of vertical temperature gradients, and scalable fabrication remains a major challenge exacerbated by the inherent brittleness of most inorganic thermoelectric materials. We report a TEG where cotton yarn serves as a flexible substrate that is coated with silver selenide (Ag 2 Se), which is an intrinsically ductile thermoelectric material. Ag 2 Se is coated on cotton yarns by a simple solution process that eliminates the need for high temperatures while preserving scalability and mechanical flexibility. Systematic optimization of the Ag 2 Se-coated yarns resulted in a figure of merit of 0.343 at 295 K. A yarn-based TEG was fabricated that maintained excellent durability over 5000 bending cycles with a 6 mm radius of curvature. Under real-world conditions for wearable applications, the yarn TEG generated 0.326 µW at a temperature difference of 2.8 K (stationary) and 0.604 µW at a temperature difference of 4.4 K (walking). This work establishes a scalable and practical platform for integrating high-performance inorganic thermoelectric materials into flexible and wearable energy-harvesting systems.

Oriented diffusion tailors interfacial strain-polarization coupling for broadband electromagnetic absorption Repurposing the interfacial strain from a hindrance to synergism empowers critical advances for magnetoelectric composites in the application of next-generation energy storage and electromagnetic devices, by reconstructing the interfacial activity and local field distributions. However, its deterministic creation, pivotal for optimizing interfacial electron transport and emergent functionality, is impeded by the uncontrollable atomic distortion and arrangement. Here, we report an oriented-diffusion strategy that tailors interfacial strain by orchestrating atomic migration within a carbon-confined Fe<sub>3</sub>C/ZnO magnetoelectric heterointerface. Engineering the outward effusion of dielectric ZnO generates a progressive strain gradient, driving a transition in the interfacial strain from compressive to tensile prior to eventual relaxation. This programmed strain state reconfigures atomic-scale electric fields at the heterointerface, thereby enhancing electron transports and interfacial polarization properties. Consequently, this enhancement enables the strain-mediated metamaterial outperforms conventional electromagnetic absorbers, exhibiting an ultrabroad effective absorption bandwidth covers the wireless communication and radar stealth spectra (2.0-18.0 GHz) with an over 95% radiation reduction. These findings provide a novel perspective on deciphering strain-polarization coupling mechanism and guide the development of advanced broadband magnetoelectric functional materials.

In situ high temperature X-ray diffraction and dilatometric analysis of CGO–Cu composites for solid oxide devices Understanding the thermo-mechanical compatibility of composite electrodes is essential for the long-term reliability of solid-oxide electrochemical devices. In this study, we demonstrate a combined in situ synchrotron X-ray diffraction (XRD) and simultaneous dilatometry approach as a rapid and predictive method to quantify both phase-resolved and bulk thermal expansion while tracking microstructural evolution at operational temperatures. Ce<sub>0.8</sub>Gd<sub>0.2</sub>O<sub>2-δ</sub>-Cu (CGO-Cu) composites with varying CGO: Cu ratios (39:61-70:30 vol%) were synthesized as potential anode materials compatible with CGO electrolytes up to 800 °C. In situ XRD confirmed only the CGO and Cu phases, with Rietveld refinement revealing a slight lattice expansion and reduced CGO crystallite size with increasing CGO content. Concurrent dilatometry indicated systematic changes in the macroscopic thermal expansion and densification behavior, which correlated with the phase and microstructural evolution observed during heating. The CGO-Cu (59:41) composite exhibited a nearly temperature-independent coefficient of thermal expansion consistent with the rule-of-mixtures predictions and minimal high-temperature shrinkage. These findings validate the combined in situ synchrotron XRD + dilatometry methodology as a powerful approach for characterizing and capturing the TEC characteristics of cermets, and for guiding the design of thermomechanically compatible oxide-metal composites for high temperature electrochemical applications.

Development of environmentally friendly dyeing technology for textiles: DBD plasma management and green tea leaf extracts toward multifunctional cotton fabric This research explores the antimicrobial effects of dielectric barrier discharge (DBD) oxygen plasma curing combined with Zinc oxide nanoparticles (ZnO NPs) on the cotton fabric, focusing on various treatment durations (5, 10, 15, 20, and 30 min) and discharge powers (15.5-17.35 W) at a flow rate of 0.5 L/min. Green tea leaves ( Camellia sinensis ) were used to extract natural pigments, and those pigments were applied in a patterned way onto fabric, creating a printed textile design using only natural materials. After treatment with oxygen plasma and ZnO NPs, the fabric was printed with dye extracted from green tea at five different concentrations. The study evaluated the treatment’s effectiveness by analyzing surface wettability, specifically through wet-out time and hydrophilicity, as well as measuring contact angles. This comprehensive approach aims to understand how DBD oxygen plasma treatment and ZnO NPs change cotton fabric properties and enhance its antimicrobial potential, paving the way for innovative applications in textiles. The chemical analysis and surface morphology of the oxygen plasma/ZnO NPs-treated fabric were examined using scanning electron microscopy (SEM). Fourier transform infrared (FTIR) analysis revealed an increase in polar functional groups (-COOH, -OH, and -C≡O) on the fabric surface, contributing to enhanced hydrophilicity and functionality. The results demonstrated a significant improvement in antimicrobial effectiveness for cotton fabric treated with plasma and printing with natural extracts. Notably, this enhanced efficacy was retained even after four washing cycles, highlighting the treatment durability.

Accelerating Instrument Troubleshooting: An AI-Driven Approach to Eliminating O The analysis of trace impurities in ultra-high purity oxygen (UPO) via GC-HDID is critically dependent on the O2 trap’s performance, where recurring breakthroughs pose a significant challenge. This paper presents an innovative troubleshooting framework that dramatically accelerates problem resolution by integrating AI, contrasting sharply with traditional, time-consuming methods. Conventional approaches involve laborious cycles of manual review, broad internet and literature searches, and multiple consultations before a testable solution can be proposed. Our novel workflow bypasses these inefficiencies. We fed instrument manuals and raw failure data from a ’T Instrument’ directly into an AI model (Gemini) for a “deep research” phase. However, initial AI outputs were too broad, identifying general-purpose purifiers rather than the specific, regenerable O2 trap in question, as many manufacturers do not disclose these proprietary details. Here, operator expertise became crucial. We iteratively tuned the AI’s research, refining our queries to focus on the specific context of regenerable, copper-based catalysts used for GC matrix removal. This expert-guided “deep research” successfully filtered out irrelevant information and led the AI to confirm a universal, underlying chemical principle—the copper redox reaction (2Cu+O2→2CuO; CuO+H2→Cu+H2O)—across different manufacturers’ traps. This pivotal, AI-generated insight, achieved through expert-led refinement, enabled a swift and accurate diagnosis when combined with operator experience. The root cause was not the regeneration reaction itself, but the incomplete removal of its H2O byproduct. The solution was therefore clear: significantly extend the total duration of the high-temperature helium purge across both the ’Heater’ and ’Standby’ phases. This optimized protocol completely eliminated breakthrough events. This AI-augmented methodology, where human expertise directs AI’s powerful analytical capabilities, represents a paradigm shift, saving considerable time on unfocused research and meetings, and presents a powerful, transferable framework for rapidly solving complex instrumentation challenges in gas analysis.
