Here, we report the first study of reprocessability and properties non-isocyanate polythiourethane (NIPTU) networks in which cross-links are two types, thionourethane disulfide, latter obtained by auto-oxidation pendant thiol groups. Our NIPTU biowaste based because starting materials can be derived from cashew nutshells or rice husks. We use dynamic mechanical analysis, tensile testing, water sorption studies to compare our with structurally analogous polyhydroxyurethane (PHU) networks, polyurethanes (PUs). With significant advantages reactivity, properties, cross-link density, favorable alternatives PHU networks. biobased also exhibit better resistance, a factor ∼3 reductions relative their analogues. Due covalent cross-links, NIPTUs show excellent complete recovery density after multiple reprocessing steps as well potential self-healing polymers. Although creep viscosity activation energies differ 2, both resistance up 80–100 °C. Thus, elevated-temperature many applications, e.g., water-resistant coatings, favored substitutes for PU

The quest for sustainable and environmentally friendly fuel feedstocks has led to the exploration of green solvents extraction bio-oil from various biomass sources. This review paper provides a comprehensive analysis challenges future research outlooks different categories solvents, including bio-based water-based supercritical fluids, deep eutectic (DES). background each solvent category is discussed, highlighting their potential advantages limitations. Challenges such as feedstock sourcing, cost fluctuations, properties variability, limited compatibility, solute solubility, high costs, toxicity are identified examined in detail. To overcome these challenges, should focus on alternative abundant sources, development improved solubility separation techniques, optimization process parameters, cost-effective equipment design, standardization DES compositions, toxicological studies. By addressing advancing areas, can be further enhanced, promoting widespread adoption contributing more industrial processes.

Exopolysaccharides (EPSs) are a diverse class of biopolymers synthesized by microorganisms under environmental stress conditions, such as pH, temperature, light intensity, and salinity. They offer biodegradable environmentally friendly alternatives to synthetic polymers. Their structural versatility functional properties make them unique in various industries, including food, pharmaceuticals, biomedicine, cosmetics, textiles, petroleum, remediation. In this way, among the well-known EPSs, homopolysaccharides like dextran, bacterial cellulose, curdlan, levan, well heteropolysaccharides xanthan gum, alginate, gellan, kefiran, have found widespread applications numerous fields. However, recent attention has focused on potential role extremophile bacteria producing EPSs with novel unusual protective biological features extreme conditions. Therefore, review provides an overview commonly employed EPSs. It emphasizes their importance industries scientific endeavors while highlighting raised interest exploring compositions, structures, properties, underexplored functionalities. Nevertheless, despite benefits challenges persist. Hence, discusses these challenges, explores opportunities, outlines future directions, focusing impact developing innovative, sustainable, materials.
