1. Synthesis, Vibrational Spectroscopic and Thermal Properties of Oxocarbon Cross‑Linked Chitosan
In this work specimens of chitosan which have been cross-linked covalently and ionically with different oxocarbon and pseudo-oxocarbon anions have been synthesised and characterized using infrared and Raman spectroscopic techniques, solid state 13C nuclear magnetic resonance (NMR) and by thermogravimetry. According to the spectroscopic and thermal results, i

2. Characterization of squaric acid and derived materials by enhanced Raman spectroscopy (use of high performance metallic SERS substrates) / Caracterização do ácido esquárico e materiais derivados por espectrocopia Raman intensificada (uso de substratos metálicos SERS de alto desempenho)
In this Thesis Surface-Enhanced Raman Scattering (SERS) and resonance Raman spectroscopy were used for monitoring the adsorption and faradaic behavior of squaric acid and its derived species. In addition, the charge transfer salt of squarate and tetrathiofulvalene and the copolymers of squarate and pyrroles were also studied. Another theme developed in this
