TEMPO-oxidized Nanocelluloses: Surface Modification and use as Additives in Cellulosic Nanocomposites
… the work, covalent (amidation) and non-covalent (ionic complexation) coupling were compared as treatment techniques for the hydrophobization of TONc surfaces with octadecylamine (ODA). Subsequently, TONc and its covalently coupled derivative were evaluated as nanofiber reinforcements in a …

Novel Carbopol-Wax Blends for Controlled Release Oral Dosage Forms
… that incomplete drug release is a result of ionic complexation and absence of tablet erosion. Thus, by selecting appropriate carbopol grade, extent of ionic complexation was reduced and by using soluble filler in the formulation, an USP compliant controlled release oral formulation of …

Self-assembly and selective swelling in Lamellar block copolymer photonic gels
… in the lamellar BCP film. Proteins can form ionic complexation with polyelectrolytes. The P2VP block in the lamellar PS-P2VP is converted into a polycation QP2VP by quatemization reactions. The ionic complexation between proteins and QP2VP triggers the swelling/deswelling of the QP2VP gel …

Potential Applications of Graphene-Based Membrane in Solution Purification Processes
… nanospacer. The next study evaluated synergistic ionic complexation between 1D-CNT (carbon nanotubes), 2D-GO, and PVA to overcome the permeability-selectivity trade-off. Thermal treatment of GO membranes was also investigated in this study. Later, part of this thesis is focused on developing a …

Polysaccharide-Based Nanocarriers for Improved Drug Delivery
… (PCL). Nanoparticles were fabricated via ionic complexation of the negatively charged PSA with positively charged N, N, N-trimethyl chitosan (TMC). All three nanocarriers possessed sizes close to 100 nm with low polydispersity (PDI) and high zeta potential values. Literature suggested that …

Analytical method development for structural studies of pharmaceutical and related materials in solution and solid state. An investigation of the solid forms and mechanisms of formation of cocrystal systems using vibrational spectroscopic and X-ray diffraction techniques
… solution is essential for the understanding of ionic complexation. The Raman spectroscopic technique was chosen for this purpose because it allows the identification of compounds in different states and it can give information about the molecular geometry from the analysis of the vibrational …
