Garcia, Helga Margarida Correia FerreiraDissertation presented to obtain the Ph.D degree in Chemistry ; Development of suberin films driven by an ionic liquid-based depolymerisation process Renewable resources are currently under intense investigation for a variety of different uses, for example as energy sources, for the extraction of value-added chemicals and for the production of novel materials. Nature offers an outstanding diversity of inimitab...
Characterization of dextrin hydrogels by FTIR spectroscopy and solid state NMR ...
Garcia, Helga; Barros, António; Gonçalves, Catarina; Gama, F. M.; Gil, Ana M.Fourier transform infrared (FTIR) and 13C solid state nuclear magnetic resonance (NMR) spectroscopy were used to study dextrin structural changes occurring upon hydrogel formation by vinyl acrylate (VA) grafting and subsequent free radical polymerization. The degrees of VA substitution (DS) and polymerization (DP) were quantified up to 40%VA by FTIR intensity measurements and partial least squares (PLS)/FTIR, t...
