Electrochemical Impedance Spectroscopy (EIS) constitutes a powerful tool to evaluate physicochemical changes in fruits and their quality during ripening and rotting. However, its widespread application is limited by the use of non-biodegradable, short-term adhesive electrodes and low-throughput, contact-inconsistent setups. Here, we present an EIS platform combining edible adhesive electrodes and a food-safe sensorized soft gripper for monitoring fruit without damage. The electrodes are fabricated from food-derived materials such as zein and activated carbon (E153) and are key to allow safe and reproducible access to fruit bioimpedance. The soft gripper, coated with food-contact safe conductive materials including gold foil (E175), polydimethylsiloxane, and activated carbon, allows reliable electrical probing. Table grapes were selected as a non-climacteric study case crop to evaluate post-harvest physiological changes under different storage temperatures. Our system enabled continuous monitoring over several days and detected significant impedance changes within the first 24 h, with refrigerated grapes showing a slower spectral variation with respect to those stored at room temperature. These findings demonstrate the potential of the proposed food-compatible EIS platform for real-time fruit quality monitoring in sustainable post-harvest supply chains.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"10 6","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.70524","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148174012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The engineered layered nanosheet morphology shortens ion diffusion pathways and enhances charge transfer kinetics. Optimizing Cr content in the Ni-LDH framework significantly improves electrochemical performance compared to pristine Ni-LDH and Cr-LDH. Structural and compositional analyses confirm effective nitrate and water intercalation, which act as pillars to prevent restacking and preserve structural integrity. The optimized NiCr-LDH exhibits a high specific capacitance of 1697 F g−1 (679 C g−1) at 1 A g−1, governed mainly by a diffusion-controlled battery-type charge storage mechanism involving partial ion intercalation.

Rising pollution stems directly from expanding mining and industrial activities, contaminating air, water, and soil. Conventional remediation relies on costly physical extraction and chemical precipitation, which require extensive infrastructure. Bioremediation using biological systems offers a sustainable, eco-friendly, and efficient alternative. This review highlights protein-based systems designed for effective bioremediation. In nature, metalloproteins like metallothioneins, phytochelatins, P-type ATPases, phosphatases, and self-assembling cages such as ferritins evolved mainly by bacteria over millions of years to remove heavy metals. These proteins sequester metals via high-affinity binding sites, while ferritin cages encapsulate them through electrostatic interactions and oxidation. Metal sequestration mechanisms are explored and studied, optimizing these via protein engineering, synthetic biology, and AI techniques for efficient biomaterials. Over the last two decades, protein systems have been used for cadmium, lead, mercury, arsenic, and uranium biomineralization. Despite successes, challenges like reusability, scalability, and cost persist. Recent advances in protein engineering and AI have yielded selective, scalable protein cage designs with engineered metal-binding sites, inspired by metalloproteins. This interdisciplinary field promises effective solutions to heavy metal pollution, gaining momentum and attracting multidisciplinary researchers for an exciting future.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"10 6","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.70495","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148174049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show that project profitability is highly sensitive to carbon credit prices. Under high-price scenarios, positive NPVs can be achieved, whereas medium and low-price scenarios consistently result in negative outcomes. Break-even thresholds are estimated at approximately 1177–1472$/tCO2 for the TEW configuration and 1300–1602$/tCO2 for the SE configuration, depending on inflation assumptions and the opportunity cost of capital. The TEW configuration appears more economically robust, exhibiting a higher likelihood of financial viability under favorable market conditions.

This complexity makes it difficult to optimize the material's morphology and phase purity using conventional single-factor methods.

This optimized TNO (denoted as O-TNO) features low-energy barriers for rapid Li+ migration and enables a highly reversible solid-solution transition mechanism. As a result, the O-TNO anode delivers a reversible specific capacity of 175.5 mAh g−1 at a high rate of 10C, with a capacity retention of 73.6% after 500 cycles.

Structural analyses confirmed that the incorporation of melamine and urea significantly influences the pore structure, surface chemistry, and electronic properties. The electrochemical behavior of these activated carbons is examined in symmetric supercapacitors and aqueous zinc (Zn)-ion capacitors (ZICs). All devices exhibited typical electric double-layer capacitor (EDLC) behavior with minor faradaic contributions. Among all samples, SAC-U ZIC delivered the highest specific capacitance (451.1 F g−1 at 0.1 A g−1), which can be attributed to its more developed porous structure and higher defect density, while SAC-M demonstrated enhanced rate capability and cycling stability in ZIC configurations. The SAC-U-based ZIC achieved a remarkable energy density of 203.0 Wh kg−1 at 90.0 W kg−1, outperforming many reported aqueous ZIC systems.
