Polymeric Approach in Microplastic Degradation Mechanisms
Abstract: Microplastics (> 5 mm size), are silently infiltrating ecosystems on a global scale. The persistence of microplastics in terrestrial and aquatic surroundingss poses a significant ecological and surroundings challenge. Thus, understanding and development of effective degradation mechanisms to mitigate the persistence of microplastics in the surroundings is required. Natural degradation pathways, such as photodegradation, biological degradation, and abiotic degradation have been explored. Polymeric materials possess unique properties that can be …

Physicochemical Transitions and Polymerization Dynamics in Multi-Generational Dentin Adhesives: A Critical Review of the Resin-Dentin Composite Interface
Abstract: Adhesive dentistry has undergone a transformative refinement over the past three decades, transitioning from technique-sensitive, multi-step etch-and-rinse protocols to streamlined universal formulations. This narrative review critically synthesizes evidence from thirty peer-reviewed investigations to evaluate the evolution of dentin bonding agents from the fourth through the eighth generations. The analysis places particular emphasis on the physicochemical dynamics of the resin-dentin interface, including interfacial bond strength metrics, marginal integrity, and microleakage behavior. …

Hydrolysis-Driven Optimization of Hydroxypropyl Maize Starch for Improved Micro-Pellet Binding and Quick Solubility of Spirulina-Based Micro-Pellets
Abstract: Acid hydrolysis is a well-established approach for modifying the physicochemical properties of polysaccharides & macromolecules including hydroxypropyl Maize starch (HPMS). In this study, the effect of varying concentrations of hydrochloric acid on the partial hydrolytic degradation of HPMS (Lycoat RS-780) was investigated at 85°C for 4 h, yielding polymers of different molecular weights. The Acid-mediated degradation effects on polymer characteristics were systematically assessed using capillary viscometry and gel permeation chromatography …

Effect of Polymer Crosslinking on Drug Release Kinetics
Abstract: In order to improve treatment effectiveness and minimise adverse effects, polymer-based drug delivery systems are often used to produce regulated and sustained drug release. Polymer crosslinking, which alters the structural, mechanical, and degrading characteristics of the polymer matrix, is one of the key elements affecting drug release kinetics. The porosity, swelling behaviour, and rate of degradation of the polymer are all impacted by the crosslinking process, which may be accomplished …

In Vivo Biocompatibility and Interfacial Stability of Thermoplastic Polyurethanes and Nanofilled Resin Composites: A Bioanalytical Study of Polymer-Host Interactions Under Dynamic Loading
Abstract: The widespread application of thermoplastic polyurethanes (TPU) and nanofilled resin composites in biomedical devices requires rigorous assessment of their biocompatibility under mechanical stress. While nanofilled composites utilize filler particles (<100 nm) to enhance surface properties and wear resistance, the biological response to these materials in a hydrolytic, enzymatic environment remains a critical area of investigation. Objective: To analyze the in vivo bio-molecular response at the interface of TPU aligners and …
