Investigation of corrosion and water absorption of biomass natural coir fiber/hBN reinforced epoxy hybrid composites using different optimisation approaches Agricultural waste or agro-waste, including natural fibers and particles from various crop parts, is increasingly recognized as a significant contributor to environmental issues. However, from a circular economy perspective, these materials present an opportunity to be repurposed into new, eco-friendly products. The present study, specifically focuses on understanding the effect of different factors, such as the particulate loading and the size (coir and hBN - 1 to 5 wt%; Coir Powder size (100-200 μm) of the particles on composite's corrosion rates and water absorption properties. These hybrid particulate composites (HPC) are fabricated using the hand layup process. The study uses a Box-Behnken Design (BBD-L15), a statistical experimental design tool that facilitates the effective investigation of many input parameters and their interactions, to comprehensively investigate these impacts. In addition, the study utilizes four metaheuristic algorithms-the Dragonfly Algorithm (DFO), the Salp Swarm Algorithm (SSA), Teaching Learning Optimization (TLO) and Particle Swarm Optimization (PSO)-alongside regression equations to predict the optimal characteristics of the composite material. To determine the best-performing algorithm, a comparison is made using Deng's method. The findings indicate that the composite with a higher weight% of hBN particulates exhibits reduced water absorption and corrosion rates. A larger Deng's Value often indicates better performance. Based on its higher Deng's Value, the SSO algorithm outperforms other algorithms in minimizing both corrosion resistance (CR) and water absorption (WA). The Deng's Value for SSO reached a maximum of 0.68, while the other algorithms show comparable but lower performance.

Recent advances in lyotropic liquid crystal nanoparticle formulations for drug delivery systems Lyotropic liquid crystalline (LLC) nanoparticles have gained significant attention as drug delivery systems owing to their unique self-assembly properties, biocompatibility, and ability to encapsulate both hydrophilic and hydrophobic drugs. This chapter explores recent advances in LLC formulations, focusing on their structural classification, physicochemical properties, and applications in controlled-drug delivery. Various mesophases, including lamellar, cubic, and hexagonal structures, have been discussed, highlighting their roles in controlled release. A comparative analysis reveals that cubic phases offer superior structural stability for sustained release, while hexagonal phases excel in high-viscosity applications, though their complex preparation limits scalability. In addition, key characterization techniques such as small-angle X-ray scattering, differential scanning calorimetry, and rheology are examined to offer insights into their stability and performance. Furthermore, the development of in situ gelling precursor systems and their applications in oral, transdermal, ocular, nasal, injectable, and periodontal drug delivery have been explored. The incorporation of stimuli-responsive materials into LLC systems enhances their adaptability to personalized medicine and advanced therapeutic strategies. Despite these advancements, challenges such as scalability, long-term stability, and clinical translation remain unresolved. This chapter highlights the potential of LLC nanoparticles to revolutionize modern drug delivery by improving bioavailability, therapeutic efficacy and patient compliance. Future research should focus on optimizing formulation strategies and exploring novel biomaterials to expand the clinical utility of LLC-based drug delivery systems.

Foam stabilization mechanism of core-shell particles: Insights from the gas-liquid interface theory To improve oil displacement efficiency under deep reservoir conditions, foam flooding technology represents a critical strategy through the establishment of a stable, long-lasting foam system. A central challenge in this application is to characterize the evolution dynamics of foam under extreme reservoir conditions such as high temperature and salinity. In this study, a performance evaluation experiment of foams generated by different types of surfactants was carried out by using the Waring-blender method. The foam stability characteristics were analyzed on the basis of foam volume, half-life of the liquid solution, and the foam comprehensive index and other related parameters. Based on the microscopic action mechanism of gas-liquid interface, the change pattern of foam performance with concentration, salinity and the coordinated action of core-shell particles were investigated. Both candidate surfactants exhibited good resistance to temperature and salinity. Among them, one surfactant demonstrated superior overall performance, with the foam comprehensive index reaching its peak at an optimal mass concentration of 0.5%. In high-salinity environments, the synergistic interaction between core-shell particles and surfactant molecules significantly enhances foam stability. In particular, the combination of this surfactant with core-shell particles at a mass fraction of 0.5% resulted in a notably higher foam comprehensive index, suggesting its strong application potential. This study quantitatively analyzes the synergistic stability effects of salinity, core-shell particles and surfactant, and reveals the synergistic stability mechanism of salt ion compression electric double layer and particle interface adsorption, providing important theoretical guidance for the development and application of deep reservoir foam flooding.

Dual role of microorganisms in metal corrosion: a review of mechanisms of corrosion promotion and inhibition The dual role of microorganisms in metal corrosion and corrosion inhibition reflects their complex biochemical interactions. In terms of corrosion, certain microorganisms accelerate metal oxidation by producing acidic metabolites or facilitating electrochemical processes, thereby causing damage to the material. Conversely, under specific conditions, they can form biofilms and/or biominerals that create protective layers, reducing the oxidation rate and delaying corrosion. This paper provides a comprehensive illustration of microbial corrosion promotion and inhibition, emphasizing the importance of key microorganisms involved in these corrosive processes. Microorganisms, including sulfate-reducing bacteria, nitrate-reducing bacteria, iron-oxidizing and iron-reducing bacteria and certain fungi, contribute to corrosion through their metabolic activities. Microbial corrosion mechanisms can be classified into extracellular electron transfer, microbial metabolism corrosion and the oxygen concentration cell theory. In contrast, microorganisms can effectively mitigate metal corrosion through a range of mechanisms including reduction of dissolved oxygen levels, secretion of antimicrobial substances, biological competition and biomineralization. Microbial corrosion and inhibition generally arise from multiple mechanisms working together, rather than a single cause. A deeper understanding of these mechanisms can provide a theoretical basis and practical guidance for the development of new anti-corrosion strategies.

Unravelling the use of nanotechnology for crop pest management as a green and sustainable agriculture Abstract Background Humans are looking for innovative options to combat major problematic biotic hurdles like crop pests (insect pests and diseases) in agriculture. Synthetic pesticides are widely employed to control pests and diseases, which leads to several issues, including pest resistance, eradication of natural enemies, contamination of the environment, biodiversity loss and health risks to humans. This review will shed light on future alternatives for crop pest management. Mani body Nanotechnology is one of the most innovative and promising alternatives for crop pest management to handle problems associated with chemical pesticides by converting the active element to nanoparticles (NPs). Because of the bigger surface area, NPs guarantee that a greater volume comes into touch with the surfaces. According to numerous research findings, nanopesticide formulations derived from NPs successfully manage crop pests and other biotic stress. They offer a long-term controlled release of the pesticide molecules, which are more environmentally friendly, selective, and target specific. Additionally, the quantity of nanopesticides needed to control insects is smaller, which lowers the chemical burden on the environment. Conclusion As an alternative to chemical molecules, nanopesticides act as a very important tool for managing insect pests and diseases. Technologies such as smart pest monitoring, precision delivery, nano-RNAi and target release nanopesticides create new avenues for pest surveillance and management. Therefore, adopting nanotechnology to develop nanopesticides and nanotools for crop pest management is thought to be the finest method in green farming for sustainable agriculture and the environment. So this article focuses more on the innovation in nanotechnology for crop pest management.

Multistage carbon coupling on three-dimensional multi-space biological templates: A novel strategy for multifunctional microwave absorption aerogel Nowadays, with the dramatic development of microwave absorbing materials (MAMs), broadband and lightweight are still a topic that cannot be bypassed. Considering the drawbacks of single-component materials and the necessity of magnetic - electric synergistic effect. A novel porous carbon-based aerogel composite with a three-dimensional (3D) biological template is prepared by using rational impedance matching design and multifunctional optimization. Specifically, the coupling of porous materials as well as the synergy of multilevel carbon materials. A novel aerogel of NiCo layered double hydroxide (LDH)/C@Diatomite (De) was prepared by thermal carbonization to convert Polypyrrole (PPy) into C particles deposited on the surface of magnetic LDH, coupled to form an aerogel on the basis of De carrier. The influence of the involvement of multilevel carbon on the electromagnetic wave absorption (EMWA) properties of the composites and its potential attenuation mechanism as well as the synergistic effect of the coupling of porous materials are revealed. As a result, the effective absorption bandwidth (EAB) is 8.56 GHz with a reflection loss minimum (RL<sub>min</sub>) of -47.15 dB at a thickness of 2.7 mm. with super hydrophobicity and thermal management properties. This work not only provides inspiration for the development of new aerogel MAMs with superior performance, but also has great potential for further development and practical application.

Engineering PHL7 for improved poly(ethylene terephthalate) depolymerization via rational design and directed evolution Enzymatic depolymerization of poly(ethylene terephthalate) (PET) has emerged as a promising approach for polyester recycling, and, to date, many natural and engineered PET hydrolase enzymes have been reported. For industrial use, PET hydrolases must achieve high depolymerization extent and exhibit excellent thermostability. Here, we engineered a natural PET hydrolase, Polyester Hydrolase Leipzig #7 (PHL7), through rational design and directed evolution using a high-throughput screening platform. Four new enzymes were engineered with enhanced properties compared with the parent enzyme, wild-type PHL7 (PHL7-WT), and other benchmark PET hydrolases, under the tested conditions. In bioreactors, the exemplary engineered enzyme, PHL7-Jemez, exhibited improved ability to depolymerize amorphous PET film compared with PHL7-WT at 2.9% and 20% substrate loadings, with 37% and 270% higher hydrolysis, respectively, after 48 h. This study develops several state-of-the-art PET hydrolases and demonstrates a directed evolution platform to engineer high-performance enzymes, which can accelerate enzyme discovery toward improved biocatalytic recycling.

Machine learning optimization of microwave-assisted extraction of phenolics and tannins from pomegranate peel The peel of pomegranate (Punica granatum) is rich in bioactive compounds, specifically phenolic compounds and tannin compounds. However, there is still a lot of difficulty dealing with the extraction of these substances due to the limitations of traditional methods. Microwave-assisted extraction (MAE) has shown promise, but optimizing it for maximum efficiency and yield remains a challenge. In this work, a microwave-assisted extraction improved using machine learning approaches was used to extract tannins and phenolic compounds from pomegranate peel. The experimental design consisted of four independent variables: microwave power (100-300 W), extraction time (10-40 min), temperature (35-50 °C), and food-to-solvent ratio (0.25-0.5 g/10 mL). The evaluated response variables were total phenolic (mg GAE/g), total tannin (mg CE/g), and antioxidant activity (DPPH scavenging activity). Thirty experiments were conducted using the microwave extraction system. Two machine learning models, LSBoost with Random Forest (LSBoost/RF) and LSBoost with K-Nearest Neighbors Neural Network (LSBoost/KNN-NN), were developed and compared for predicting extraction outcomes. The LSBoost/RF model demonstrated superior performance, achieving correlation coefficients (R²) of 0.9998, 0.9018, and 0.9269 for total phenolic, total tannin, and DPPH %, respectively. Feature importance analysis revealed microwave power as the most influential parameter, particularly for tannin content and antioxidant potency. The findings indicate that the combination of microwave-assisted extraction with machine learning provides an effective and accurate approach for the extraction and prediction of phenolic and tannin compounds in natural sources.
