Polymer Foam /Fly Ash Composites: Evaluation Of Mechanical, Interfacial, Thermal, Viscoelastic And Microstructural Properties, Parisa Khoshnoud
Theses and Dissertations
Fly ash, a byproduct of coal combustion process in power plants, consists of fine, powdery particles that are predominantly spherical in shape, either solid or hollow, and mostly glassy (amorphous) in nature. It is capable of being recovered and used as a low-cost reinforcing filler. Adding fly ash particles to a thermoplastic foam poses many challenges to understanding the physical, mechanical, viscoelastic, thermal, and morphological changes to the composite. The effects of fly ash particles on the foaming process; e.g. nucleating and growth steps, cell types and size, and microstructure need to be evaluated in order to develop a commercial …
Wetting, Superhydrophobicity, And Icephobicity In Biomimetic Composite Materials, Vahid Hejazi
Wetting, Superhydrophobicity, And Icephobicity In Biomimetic Composite Materials, Vahid Hejazi
Theses and Dissertations
Recent developments in nano- and bio-technology require new materials. Among these new classes of materials which have emerged in the recent years are biomimetic materials, which mimic structure and properties of materials found in living nature. There are a large number of biological objects including bacteria, animals and plants with properties of interest for engineers. Among these properties is the ability of the lotus leaf and other natural materials to repel water, which has inspired researchers to prepare similar surfaces. The Lotus effect involving roughness-induced superhydrophobicity is a way to design nonwetting, self-cleaning, omniphobic, icephobic, and antifouling surfaces. The range …
