    Abstract: Three solvents of different polarities (water, methanol and 1% NaOHsolution) were used to extract dyes that produced different shades fromdried sunflower (Helianthus annuus) petal. The extraction proceduresusing different solvent types were carried out separately. The dye extractswere thereafter subjected to Fourier Transform Infrared Spectrometry(FT-IR) analysis for characterization in terms of functional groups. Theintensities of the... More

    Abstract: In this research, the structural characteristics, specific surface area, sorption of water vapor, and wetting enthalpy of various polysaccharides (cellulose, hemicelluloses, starch, pectin, chitin, and chitosan) have been studied. It was confirmed that crystallites are inaccessible for water, and therefore water molecules can interact only with polar groups in noncrystalline (amorphous) domains of biopolymers. The... More

    Abstract: There are two common types of polymers (thermoplastics and thermosets), which have been classified by various methods depending on their molecular structures. The bonding of molecular chains is the fundamental physical difference between these two polymer types. The polymer types are named based on their general thermal and processing characteristics, and chemical structure,... More
