  2. Studies of polysaccharide adsorption onto model cellulose surfaces and self-assembled monolayers by surface plasmon resonance spectroscopy

    Kaya, AbdulazizVirginia Tech2009

    … at the air/water and solid/water interfaces, surface tension measurements and surface plasmon resonance (SPR) spectroscopy have been identified as key methods for the acquisition of structural and thermodynamic information. These techniques were used to determine air/water and cellulose/water …
