  • CdS nanocrystalline thin films deposited by the continuous microreactor-assisted solution deposition (MASD) process : growth mechanisms and film characterizations

    Creator:
    Su, Yu-Wei
    Abstract:
    The continuous microreactor-assisted solution deposition (MASD) process was used for the deposition of CdS thin films on fluorine-doped tin oxide (FTO) glass. The MASD system, including a T-junction micromixer and a microchannel heat exchanger is capable of isolating the homogeneous particle precipitation from the heterogeneous surface reaction. The results show...

  • Growth, Characterizations, and Applications of Patterned Nanostructured Thin Film

    Creator:
    Gao, Zhongwei
    Abstract:
    A unique microreactor-assisted nanomaterial synthesis and printing process was studied for the fabrication of patterned metal oxide nanostructured thin films. The process uses a continuous flow microreactor to control and generate a reactive chemical flux that was transported to a patterned microfluidic channel. The microreactor-assisted nanomaterial synthesis process can generate...

  • Synthesis of titanium dioxide nanorods using a continuous flow microreactor

    Creator:
    Yen, Wei-Liang
    Abstract:
    The primary goal of this thesis is to synthesize titanium dioxide nanorods using a continuous flow microreactor. Titania powder, one of the most important particulate materials is used for many purposes owing to its excellent optical properties of a high refractive index leading to high hiding power and whiteness of...

  • Synthesis and characterization of magnetic composite materials

    Creator:
    Kimmell, Robert
    Abstract:
    Iron epoxy composite materials were made and their relative magnetic permeability was measured. A measurement device was created to measure the relative magnetic permeability for the specific application. This device proved to be accurate and reliable. The magnetic properties of composite materials have been shown to be controllable, with a...

  • Use of orthogonal collocation in the dynamic simulation of staged separation processes

    Creator:
    Matandos, Marcio
    Abstract:
    Two basic approaches to reduce computational requirements for solving distillation problems have been studied: simplifications of the model based on physical approximations and order reduction techniques based on numerical approximations. Several problems have been studied using full and reduced-order techniques along with the following distillation models: Constant Molar Overflow, Constant...

  • Numerical Methods for Upscaling Complex Transport Phenomena

    Creator:
    Taghizadeh, Ehsan
    Abstract:
    Transport phenomena specially the ones that occur in the various engineering disciplines such as tissue engineering and natural environment are often complex to analyze mostly due to the dynamic and geometric complexities; as such, they have been the subject of an active and intense area of research in past decades....

  • Exploring the Wettability States and Contact Angle Variation in Porous Media Multi-Phase Flow Systems

    Creator:
    Behnoudfar, Diba
    Abstract:
    The wetting of a surface by a liquid is a crucial part of many natural and industrial processes. Despite numerous existing studies, some elements of wetting-dewetting such as contact angle variation are still poorly understood. Knowledge of contact angle behavior during the flow is necessary for modeling fluid displacements in...

  • Functional materials for advanced energy and electronic devices

    Creator:
    Flynn, Brendan T.
    Abstract:
    Advances in energy technologies and electronics have typically occurred through either heightened performance or cost reduction. This dissertation explores both routes through a series of fundamental material studies that may contribute to the enabling of next generation devices. Solution based syntheses and deposition of chemical products offer a low cost...

    Creator:
    Pan, Changqing
    Abstract:
    As a group of promising semiconductor materials, metal chalcogenides in thin film form have been widely used in electronics and optoelectronics applications, such as solar cell devices and photon sensors. Unfortunately, the film size and product throughput are limited by the current vacuum-based thin film deposition techniques. Solution-based thin film...
