Synthesis and Characterization of Polymer-Based Organic–Inorganic Hybrid Materials viaSol–Gel Processing: A Review of Gelatin–Silica, Gelatin–Silica–Titania and HPMA-Based Systems
Abstract: Organic–inorganic hybrid materials have emerged as a versatile class of advanced materials that integrate the flexibility and functionality of organic polymers with the thermal, mechanical, and chemical stability of inorganic networks. Among the available fabrication routes, the sol–gel process has gained considerable attention because of its simplicity, low processing temperature, compositional flexibility, and ability to tailor material properties at the molecular level. The present review discusses the synthesis and characterization …

Design and Commercial Validation of a Hierarchical Three-Tier Quality GradingSystem for Post-Industrial and Post-Consumer Recycled Thermoplastic Resins in US Industrial SupplyChains
Abstract: Quality grading systems for recycled thermoplastic resins providing industrial buyers with a standardized, documented quality classification framework for secondary raw material procurement are a foundational requirement for the reliable integration of recycled materials into industrial supply chains. Despite this requirement, no standardized grading scale has been established for post- industrial and post-consumer PP, HDPE, and LDPE resins in industrial supply chain contexts. This paper presents the design, operational implementation, and …
