Summary: Chitosan/aspartic acid hydrogels were synthesized for the removal of MB dye from textile aqueous effluents. The hydrogels were characterized and confirmed to have successful preparations and MB dye adsorption. Batch experiments were conducted to investigate the effects of various factors on the adsorption process. The optimized conditions were determined for each hydrogel. The adsorption capacities of the hydrogels were compared, and both followed Freundlich isotherm model and pseudo-second-order kinetics for adsorption.

Summary: Novel starch phosphate grafted polyvinyl imidazole (StP-g-PIMDZs) was synthesized by attaching a phosphate group to starch polymer and grafting 1-vinyl imidazole onto the backbone of starch phosphate. The modified starches showed diminished crystallinity and increased thermal stability. They also exhibited high adsorption capacity for methylene blue dye, with StP-g-PIMDZ 3 achieving a maximum removal percentage of 95.4%. The adsorption process followed a pseudo second order kinetic model and Langmuir adsorption isotherm, and was thermodynamically feasible, spontaneous, endothermic, and favored chemi-sorption mechanism.

Summary: The chemical cross-linking of carboxymethyl chitosan was used to obtain a novel hydrogel for efficient removal of Methylene Blue dye from aqueous solution. Factors such as temperature and pH were found to significantly impact the adsorption capacity of the hydrogel, with higher temperatures and pH values leading to increased adsorption. The pseudo-second-order mechanism was found to be predominant in the adsorption process, with the Langmuir model showing high applicability.

Summary: In this study, raw talc powder was surface modified using two different methods: acid washing and ball milling. XRD, FTIR, and SEM were used to characterize the modified talc. Adsorption experiments were conducted using methylene blue (MB) as the target contaminant, and the findings showed that both modifications increased the adsorption capacity of talc. The results indicate that modified talc can be an inexpensive and abundant candidate material for dye adsorption in industrial wastewater.

Summary: In this study, Agar-carboxymethylcellulose-silver nanoparticle (AG-CMC-AgNP) nanocomposite was successfully fabricated and characterized. The adsorption of methylene blue (MB) dye onto AG-CMC-AgNP was investigated, and the results showed that AG-CMC-AgNP had a high adsorption capacity and good adsorption performance for MB. The adsorption process followed the Langmuir isotherm and pseudo-second-order reaction kinetic model. The biosorbent was found to be reusable, although the adsorption capacity slightly decreased after multiple cycles.

Summary: This study aimed to find a biobinder for producing waterproof or water-resistant coal briquettes from Slater coal slurry of South Africa. Molasses and crude glycerol were used as raw materials for the binders, resulting in higher tensile strength when based on crude glycerol citric acid ester. Waterproof briquettes were achieved by blending phosphoric acid-hardened molasses with glycerol citric acid ester-based binders, with the best results when blended at 50%.

Summary: This study investigates the effect of the network structure of hydrogels on the performance of quasi-solid gel electrolytes in DSSCs. Increasing cross-linking during synthesis improves conductivity but does not necessarily increase energy conversion efficiency in DSSCs. Cross-linking also affects the swelling, wetting, and morphological properties of the hydrogels.

Summary: Since alkyd resins contain hazardous solvents, it is important to convert them into waterborne hybrid polymers. In this study, alkyd/styrene acrylic waterborne hybrid polymers were synthesized using synthesized alkyd resins and different biosources. The synthesized latexes and their films were analyzed, and it was found that the type and concentration of the alkyds affected various properties. Experiments on waterborne paint systems showed that the alkyd content did not affect the paint color, indicating that hybrid waterborne latexes could be used for exterior paints.
