Recent advances in corrosion behaviour and interfacial failure of rubber–metal composites G. Aswin, V. Prakash, N. Subasree, V. Arul, Prabhu Paramasivam, Lalitha Gnanasekaran, M. Santhamoorthy, K. Radhakrishnan Npj Materials Degradation, 2026 Rubber- Metal Composite are extensively used in automotive, aerospace and offshore industry as well as in the industry due to its flexibility, damping, and mechanical strength. Their work is however limited regularly through failure between interfaces and corrosion in highly aggressive conditions such as exposure to saline, thermal cycling, and mechanical fatigue. The review highlights recent advances in the study of corrosion behavior and interfacial degradation mechanisms of rubber-metal systems, as well as the effects of different formulations, vulcanization processes, surface modification, and filler engineering on adhesion, fatigue, and wear resistance. The new tendencies reflect a shift away from descriptive observation and toward mechanism-based insights, which are aided by the use of multi-scale modeling and real-time sensing to forecast crack initiation and interfacial delamination. New corrosion mitigation technologies are being reinterpreted in sustainable directions such as bio-based fillers, recycled rubber, and circular material design, with the goal of generating greener, more durable solutions. This review integrates experimental and computational insights to map the pathways to improved interfacial dependability, environmental resilience, and next-generation performance of rubber-metal composites.
Process Engineering Strategies for Enzyme- and Microbial-Based Food Waste Valorization Towards Circular Food Manufacturing V. Prakash, N. Subasree, V. Arul, P. Saravanan, G. Lakshmi, K. Radhakrishnan, Jothi Vinoth Kumar, S. Munusamy, Baskaran Stephen Inbaraj, S. Rajkumar Journal of Food Process Engineering, 2026 Food waste is a key sustainability issue in the world, and it leads to environmental pollution, inefficient use of resources, and financial loss. The concept of biological valorization has been identified as one of the promising approaches to transform food and agro‐industrial wastes into high‐value products in a circular bioeconomy and supports sustainable production systems. Although each of the studies has been conducted with the purpose of examining enzymatic or microbial processing alone, there is little in the way of an integrated insight into the combined and process‐engineered applications. This review gives a broad and process‐based view of what has been achieved in enzyme‐ and microbe‐assisted food waste valorization with an emphasis on the recent developments in enzymatic hydrolysis, microbial fermentation, and new hybrid platforms that combine these two catalytic systems through innovative manufacturing processes. Special attention is given to multi‐enzyme cascades, co‐culture fermentation, electrofermentation, and bioelectrochemical systems, which contribute to an increase in substrate conversion efficiency, product selectivity, and overall sustainability. Next‐generation techniques that are discussed in the review include the engineering of enzymes, microbial selection by metagenomics, genetically engineered microorganisms, and process optimization through artificial intelligence. In addition, urban biorefineries represent promising platforms for integrated waste management, enabling efficient conversion of food residues into value‐added bio‐based products. Combining enzymatic and microbial methods with contemporary process engineering mechanisms, this review suggests a comprehensive framework of systems design in creating an efficient system of biological valorization, which can guide researchers and industry to sustainable management of food waste and bioreactor product development.
Materials Engineering of Elastomer–Metal Interfaces Under Corrosion, Wear, and Adhesion Stressors S. Bhuvanesh, V. Prakash, V. Arul, P. Saravanan, N. Subasree, K. Radhakrishnan, R. Suriyaprakash, Mohammed Alsawat, M. Sherlin Nivetha, Jothi Vinoth Kumar JOM, 2026 Elastomer–metal interfaces find applications in the automotive, aerospace, and biomedical industries, and are affected by environmental degradation, which is mainly corrosion, wear, and adhesion failure. Harsh service conditions, such as wet conditions, changes in temperatures, chemicals, mechanical forces contribute to the interfacial weakening process due to electrochemical reactions, crack propagation, and delamination, eventually cause a failure of the system. This review highlights the fundamental pathways of interfacial degradation and the interaction effect that occur between chemical, mechanical, and environmental stressors. An integrated system of chemo-mechanical–environmental degradation is considered, whereby corrosion, wear, loss of adhesion, and mechanical fatigue are not considered independent processes but rather they interact. This model emphasizes the acceleration of other stressors, which is caused by the damage of one stressor and by the feedback of other stressors at the elastomer–metal interface. The methods of mitigation are discussed, as well as surface treatment, incorporation of nanoparticles to strengthen the composite, the application of special adhesives, and bioinspired alternatives, such as sacrificial bonding and self-healing. Recent development of multifunctional elastomer–metal composites exhibit toughness and damping, corrosion resistance, and bond durability. Other issues highlight the importance of additional studies to solve the complexity of synergistic degradation in real-life scenarios. Smart coatings, predictive modeling, and resilient, sustainable, and adaptive materials are some of the future opportunities.
Visible-Light-Driven Photocatalytic Degradation of Amoxicillin Using FeMoO2/Chitosan/CdO Nanocomposite for Sustainable Water Treatment V. Arul, K. Radhakrishnan, N. Kasthuri, D. Senthil Vadivu, J. Vinoth Kumar, M. Sherlin Nivetha, R. Mythili, Sandhanasamy Devanesan Polymers for Advanced Technologies, 2025 This work focused on the photocatalytic degradation of amoxicillin using the recently developed FeMoO4/chitosan/CdO nanocomposite (FeMoO4/CS/CdO). The most typical antibiotic, amoxicillin, raises environmental threats due to its persistence in aquatic environments. Amoxicillin, extensively utilized as an antibiotic, has environmental concerns due to its existence in aquatic environments. The nanocomposite, comprising iron molybdate (FeMoO4), chitosan (CS), and cadmium oxide (CdO) nanoparticles, was synthesized to couple the distinct properties of each constituent, enhancing its overall functionality. FCC‐NC was characterized by the presence of clearly defined peaks in the infrared (IR) spectra, ultraviolet–visible (UV–Vis) spectra, and x‐ray diffraction (XRD) patterns. We studied the photocatalytic degradation of amoxicillin (AXM) using the FeMoO4/CS/CdO nanocomposite. Under ideal conditions (40 mg catalyst dosage and 10 mg/L initial AXM concentration), we achieved a degradation efficiency of roughly 90.8%, following pseudo‐first‐order kinetics with a rate constant of 0.0222 min−1. The immobilized FeMoO2/chitosan/CdO nanocomposite was more photocatalytically active than bare FeMoO2 because it exhibited less charge carrier recombination, according to EIS and PL analysis. Hence, the FeMoO4/chitosan/CdO nanocomposite has a vast opportunity in the long‐term mechanism of eradicating pharmaceutical pollutants in water. This study shows that the obtained results may be useful in the field of environmental cleanliness and water purification technologies.
