Fabrication and characterization of inverse opals with tunable stopbands
Madduma-Bandarage, Ujith S. K. (2018-12)Inverse opals, a major type of self-assembled structures, provide good examples of photonic crystals that result from the periodic arrangement of voids. The periodic arrays of voids interfere with the light passing through ... -
Fabrication, swelling, and biological properties of surface-patterned hydrogels based on poly(2-hydroxyethyl methacrylate)
Jaysinghe Arachchige Dona, Hasani G. J. (2018-12)Hydrogels are networks of hydrophilic polymers which can retain large amounts of water. Poly(2-hydroxyethyl methacrylate) [poly(HEMA)] is a synthetic hydrogel well known for various biomedical applications due to excellent ... -
Improved stem cell retention and mechanical stability in a chitosan-gelatin hydrogel
Tormos, Christian Jose (2016-07)Due to the heart's poor regenerative ability, new treatments need to be developed in order to repair damaged cardiac tissue after cardiac arrest. A common approach is to deliver adult stem cells combined with injectable ... -
Novel syntheses and applications of layered transition metal hydroxides
Russel Rahman, Dewan (2022-07)The dissertation herein reports the serendipitous discovery of hydrolysis reactions of later 3d transition metal acetates that deposit nanostructured thin films of corresponding layered metal hydroxides, M(OAc)2-x(OH)x·nH2O ... -
Solution-based synthetic strategies, characterizations, and applications of nanoparticles
Wang, Yi-Wei (2019-05)Nanomaterials have attracted great attention in the past decades due to their unique properties. Up to the present time, various nanoparticles with tunable size and shape have been produced using solution-based synthetic ... -
Superhyrophobicity and structures of adsorbed silane coupling agents on silica and diatomaceous earth
Perera, M. A. Helanka Jayani (2016-07)Superhydrophobic coatings were prepared using fluorosilane treated diatomaceous earth (DE) with either polyurethane or epoxy binders and the results were compared. The water contact angles were studied as a function of the ... -
Synthesis and applications of tungsten and vanadium oxides/oxyhydroxides in both bulk and nanoparticulate forms
Alothman, Asma Abdullah (2016-12)The reactions of tungstic acid towards alkenes, alkynes, and nitriles were explored in order to determine the scope of its reactions with unsaturated hydrocarbons. The chemistry was found to be complex with small changes ... -
Synthetic strategies for generating inorganic nanoparticles with optical, catalytic, and biological importance
Fernando, Kachchakaduge Deshani Gihanthika (2017-12)Solution-based synthesis methods have been widely used to synthesize nanocrystals as it provides control over the size and shape. As a result of the rapid success of the solution based synthesis methods, new applications ...
