7. Alkoxide complexes of rhenium - precursors of nanomaterials
Abstract : The thesis presents the work constituted by two major parts: (1) – synthesis of new mono-, bi- and trimetallic complexes based on Re, Nb and Ta and their physical-chemical characterization, and (2) – preparation of nanostructural functional materials derived from these complexes. The precursors and materials were characterized by FTIR, NMR, MS, SEM–EDS, TEM and X-ray diffraction. READ MORE

9. UDP-sugar metabolizing pyrophosphorylases in plants : formation of precursors for essential glycosylation-reactions
Abstract : UDP-sugar metabolizing pyrophosphorylases provide the primary mechanism for de novo synthesis of UDP-sugars, which can then be used for myriads of glycosyltranferase reactions, producing cell wall carbohydrates, sucrose, glycoproteins and glycolipids, as well as many other glycosylated compounds. The pyrophosphorylases can be divided into three families: UDP-Glc pyrophosphorylase (UGPase), UDP-sugar pyrophosphorylase (USPase) and UDP-N-acety lglucosamine pyrophosphorylase (UAGPase), which can be discriminated both by differences in accepted substrate range and amino acid sequences.

10. Biobased carbon fibers from solution spun lignocellulosic precursors
Abstract : Carbon fibers (CFs) have excellent mechanical properties and a low density, making themattractive as a reinforcing fiber in composites. The use of CFs is limited to high-end applications,since they are produced from an expensive fossil-based precursor via an energy-intensivemanufacturing process, explaining the need for cheaper CFs from renewables.
