  • New application of crystalline cellulose in rubber composites

    Creator:
    Bai, Wen
    Abstract:
    Rubber without reinforcement has limited applications. The strength of reinforced rubber composites can be ten times stronger than that of unreinforced rubbers. Therefore, rubber composites are widely used in various applications ranging from automobile tires to seals, valves, and gaskets because of their excellent mechanical elastic properties. Silica and carbon...

  • Investigation of Styrene-Free Unsaturated Polyester Resins for Fiber-Reinforced Composites

    Creator:
    Wu, Yili
    Abstract:
    Most of existing commercial unsaturated polyester (UPE) resins are typically composed of a UPE and a high amount of highly volatile, flammable, and toxic styrene. The emission of hazardous styrene in the handling of the UPE resins and the preparation and use of fiber-reinforced UPE composites poses severe hazards to...

  • Pressure sensitive adhesives based on oleic acid

    Creator:
    Wu, Yili
    Abstract:
    Existing pressure sensitive adhesives (PSAs) are mostly based on petrochemicals. In this study, a novel PSA based on a renewable material, methyl oleate, was prepared and characterized. Methyl oleate was first epoxidized to form epoxidized methyl oleate that was subsequently hydrolyzed and acidified to form epoxidized oleic acid (EOA) which...

  • Novel Interfacial Syntheses of Covalent Organic Frameworks

    Creator:
    Liu, Ziyan
    Abstract:
    Covalent organic frameworks (COFs) are an emerging type of microporous crystalline polymers connected by organic units via strong covalent bonds. Due to the well-defined crystalline structure and excellent chemical and thermal stabilities, COF materials are being considered as promising candidates in a variety of applications, such as gas adsorption, catalysis...

  • Fabrication and characterization of ferrimagnetic film for RF/microwave crosstalk suppression

    Creator:
    Su, Yu-Wei
    Abstract:
    The primary goal of this thesis is to fabricate a magnetic film between the coplanar transmitted stripline for crosstalk suppression. Crosstalk is caused from undesired inductive and capacitive coupling of signals between two conductors. The effective crosstalk suppression results from the inductive coupling of circuit elements through the lossy properties...

  • Formation of Cu₂ZnSnS₄ Thin Films via Reactive Sintering of Binary Metal-Sulfide Nanoparticles Using Intense Pulsed Light

    Creator:
    Zeng, Cheng
    Abstract:
    Copper zinc tin sulfide (CZTS) is a potential solar material for thin film solar cells according to its suitable band gap in the visible light range, high absorption coefficient, low toxicity, good photostability and relative earth abundance of component elements. However, the production cost of this solar thin film material...

  • Continuous flow synthesis of lead sulfide and copper indium diselenide nanocrystals

    Creator:
    Knapp, Michael W.
    Abstract:
    The use of size and shape tunable quantum confinement nanocrystals has many potential applications for use in semiconductors, optics and sensors. The synthesis of lead sulfide (PbS) and copper indium diselenide (CuInSe₂) nanoparticles are of particular interest for use in semiconductor, optoelectronics and bio-medical applications. The continuous synthesis of lead...

  • Continuous and rapid synthesis of nanoclusters and nanocrystals using scalable microstructured reactors

    Creator:
    Jin, Hyung Dae
    Abstract:
    Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...

  • Investigation of low temperature solution-based deposition process for flexible electronics

    Creator:
    Chang, Yu-Jen
    Abstract:
    The critical contribution of this dissertation is to provide a better understanding of the fundamental Chemical Bath Deposition (CBD) growth kinetic and mechanism for the well known II-VI semiconductor CdS using the newly developed continuous flow microreactor. This continuous flow microreactor provides the temporal resolution to control the homogeneous reaction...

  • Solution-based Chalcogenide Thin Film Deposition

    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...
