Polymer materials

Is a branch of polymer science dealing with analysis and characterisation of polymers. üThe complication of macromolecular chains, the dispersion in molecular weight, tacticity, crystallinity, orientation, composition of polymers etc. and complex morphological systems ⇒ analysis of polymer ≠ the small organic materials ⇒ Focus on viscoelastic properties, dynamic mechanical testing.

- Polysaccharides are macromolecules, polymers with a few hundred to a few thousand monosaccharides joined by glycosidic linkages. - Some polysaccharides serve as storage material, hydrolyzed as needed to provide sugar for cells. - Other polysaccharides serve as building material for structures that protect the cell or the whole organism. - The architecture and function of a polysaccharide are determined by its sugar monomers and by the positions of its glycosidic linkages.

Currently, the ability to convert raw materials from lignocellulose-rich biomass by traditional methods has many limitations. Therefore, the objective of the thesis is to exploit a variety of biocatalysts (hydrolases) from fungi to efficiently convert lignocellulose-rich biomass from ABP into sugars (C5 and C6) capable of fermenting for bioethanol production. The thesis uses "enzyme cocktail" synergistic catalyst to increase the ability of biological transformation.

Composite materials show different mechanical properties in different directions which leads to complications in the prediction of their behavior. In addition to being inhomogeneous, behavior of composite materials is highly dependent on the curing process and many studies have tried to address these issues.
