The phase behavior of anisotropic nanodiscs of different aspect ratio in their individual and mixed states in aqueous and hydrophobic media is investigated. Distinct phase separation, equilibrium fluid and equilibrium gel phases are observed in nanoclay dispersions with extensive aging. The work then explores solution behavior, gelation kinetics, aging dynamics and temperature-induced ordering in the individual and mixed states of these discotic colloids. Anisotropic ordering dynamics induced by a water-air interface, waiting time and temperature in these dispersions were studied in great detail along with aggregation behavior of nanoplatelets in hydrophobic environment of alcohol solutions.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Amorphous substancesComplex fluidsCeramicsGlassComposite materialsComposite materialsChemistry, Physical and theoreticalNanotechnologySoft and Granular Matter, Complex Fluids and Microfluidicshttps://scigraph.springernature.com/ontologies/product-market-codes/P25021Ceramics, Glass, Composites, Natural Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z18000Physical Chemistryhttps://scigraph.springernature.com/ontologies/product-market-codes/C21001Nanotechnologyhttps://scigraph.springernature.com/ontologies/product-market-codes/Z14000Amorphous substances.Complex fluids.Ceramics.Glass.Composite materials.Composite materials.Chemistry, Physical and theoretical.Nanotechnology.Soft and Granular Matter, Complex Fluids and Microfluidics.Ceramics, Glass, Composites, Natural Materials.Physical Chemistry.Nanotechnology.541.345Pujala Ravi Kumarauthttp://id.loc.gov/vocabulary/relators/aut791799MiAaPQMiAaPQMiAaPQBOOK9910300384503321Dispersion Stability, Microstructure and Phase Transition of Anisotropic Nanodiscs1770412UNINA
