The utilization of renewable materials has raised worldwide interest regarding biodegradable polymers, proving important scientific, ecological, and economic relevance. Biopolymers are versatile materials used in various applications due to their high strength, low weight, and minimal environmental impact. However, their characterization for understanding their properties requires extensive experimental measurement. In this context, conventional research is improved by the integration of artificial intelligence (A...

The presence of nitrate concentration in drinking water can cause high toxicity to the human body, being considered among the most important pollutant in the environment. Among the many methods available such as biological treatment, electrodialysis, reverse osmosis, adsorption, ion exchange, adsorption is the most used technique due to its low cost and simplistic design. Therefore, the aim of this paper was to study the retention of nitrate anion from high concentration aqueous solutions on a novel magnetic adsor...

Fish oils with a high content of polyunsaturated fatty acids (PUFAs) are gaining increasing interest in the food and nutraceutical industry, due to their important functional properties for human beings- health improvement. The most important PUFAs have at least two double bonds placed on the carbon chain. These include ?-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahaxaneoic acid (DHA). Microencapsulation is a technique used to protect the bioactive compounds from oxidative damage, to ensure their ...

The aim of this work is to optimize the growth parameters of D. salina by altering nutritional factors, in order to maximize production of antioxidants and lipid fraction by the microalgae strain. For this purpose, the concentrations of different salts in the growth medium were varied. The biomass obtained was analyzed quantitatively and qualitatively in order to determine biomass concentration and bioactive compounds concentrations in respect to the growth medium composition. Pigments were extracted from the drie...

One of the most abundant renewable resources with a great potential as raw materials for production of fuels and bulk chemicals are carbohydrates derived from biomass. Among these, esters levulinates have been widely used as solvents and plasticizers in food industry or as fuels additives for transportation. The direct synthesis of methyl levulinate from fructose over solid superacid SO42?/TiO2-La2O3 catalyst was investigated in this study. The influence of different reaction parameters such as reaction temperatur...
