6. Catanionic Aggregates in Gels : Prolonged Drug Release and Potential Implications for Topical Use
Abstract : Gels are popular dosage forms. This topical dosage form may be advantageous compared to oral or parenteral dosage forms. Favorable rheological or bioadhesive properties of gels might provide extended contact times at the site of administration compared to aqueous solutions. READ MORE

7. Correlating Microstructure with Texture of Particulate Biopolymer Gels
Abstract : The microstructure of particulate biopolymer gels has been studied to comprehend the effect of microstructure on textural properties. Particulate structures have been characterized at different levels by using light microscopy, scanning electron microscopy, and transmission electron microscopy. READ MORE

8. Polymer Gels and their Interactions with Ionic Surfactants
Abstract : The response on chemically crosslinked gels and polymer solutions on the addition of ionic surfactants and/or addition of salt at different temperatures have been studied. All polymers studied are water soluble and slightly hydrophobic or hydrophobically modified. READ MORE

9. Structure-Control of the Rheological Behaviour of Particulate Gels
Abstract : The focus of this thesis is the relation between the rheological and structural properties of mixed particulate gels, based on β-lactoglobulin, determined under both dynamic and static conditions. Rheological characteristics were recorded during formation of the gels, on set gels and during deformation and fracture of the gels, using viscoelastic measurements in shear and in compression and fracture mechanics in tension.

10. Synthesis and Characterization of Sec-Packings Based on Trimethylolpropane Trimethacrylate
Abstract : Suspension and bulk polymerization of trimethylolpropane trimethacrylate (TRIM) and copolymerization of TRIM with methyl methacrylate (MMA) resulted in porous, hydrophobic, and chemically crosslinked networks. Copolymerization of TRIM with acrylamide (AA) and with N,N'-methylene-bis-acrylamide (bis-AA) resulted in hydrophilic gels. READ MORE
