  • 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...

  • Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

    Creator:
    Alemu, Yagenetfere A.
    Abstract:
    The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...

  • Spray drying for erythrocyte preservation at room temperature

    Creator:
    Leu, Hsuan-Yu
    Abstract:
    Spray drying has been widely used in food science for long-term storage of products such as powdered milk, and it has recently been used for preservation of more temperature sensitive products such as human blood plasma and single-cell organisms. However, there are no previous reports of successful spray drying of...

  • Analysis and modeling of substrate noise coupling for NMOS transistors in heavily doped substrates

    Creator:
    Hsu, Shu-ching
    Abstract:
    This thesis examines substrate noise coupling for NMOS transistors in heavily doped substrates. The study begins with the analysis of an NMOS transistor switching noise in a digital inverter at the device level. A resistive substrate network for the NMOS transistor is proposed and verified. Coupling between N+- P+ contacts...

  • A comprehensive integration of first year engineering education

    Creator:
    Shuman, Matthew W.
    Abstract:
    Retention of engineering students is a problem for many universities, especially during the first year. The problem of introducing students to engineering while increasing retention rates has recently been addressed by many different universities. Implementing novel lab structures, adjusting the lecture to incorporate more effective teaching techniques, and using orientation...

  • Fabrication of Biological Pigment Nanowires by Inkjet Printing

    Creator:
    Cao, Yu
    Abstract:
    Digital inkjet printing is developing quickly today because inkjet printing processes consume less energy and water and produce less waste discharge than traditional dyeing and other printing technologies. Inkjet printing provides more versatility and flexibility in terms of printing patterns and colors. Natural pigments are gaining more attention today as...

  • Investigating the Effect of Tetrahydrofuran (THF) Plasticizer on the Crystallization and Solvent Seaming of PET/NPG Copolymer Films

    Creator:
    Srivastava, Aarushi
    Abstract:
    Polyethylene terephthalate (PET) polymer has been the material of choice for packaging industry as a result of its excellent mechanical and physical properties. These properties are highly dependent on the microstructure, chemistry, and processing conditions of this material. PET is often oriented in the machine direction (MD), the transverse direction...

  • Experimental Study of Nucleate Boiling Bubble Dynamics and Heat Transfer Enhancement on Printed Bi-functional Surfaces

    Creator:
    David, Michele
    Abstract:
    Boiling heat transfer is studied for its ability to dissipate high fluxes and achieve heat transfer coefficients two orders of magnitude greater than single-phase heat transfer systems. Heater surface enhancement with increased surface area, varied geometry, wettability contrast and micro/nano-structures can further enhance boiling heat transfer performance through bubble nucleation...

  • Development of a test method for assessing water repellency and derived physical stability of preservative systems for railroad ties

    Creator:
    Beck, H. Greeley
    Abstract:
    Resistance to moisture uptake is an important attribute of some wood preservatives and can help reduce moisture cycling that leads to the development of deep checks. While the potential for preservative treatments to help improve wood/moisture interactions is acknowledged, there are no tests that specifically evaluate this performance parameter. Checking...

  • Microchannel extraction of Te⁴⁺ from a stream of CdTe via MIBK in supported liquid membrane

    Creator:
    Liburdy, Heather Johnson
    Abstract:
    A new technique is developed to recover elemental tellurium (Te) from cadmium telluride (CdTe) which is abundantly available in photovoltaic semiconductor waste. The method is based on microchannel fluid flow with the use of a supported liquid membrane (SLM) between the donor (feed) and acceptor (strip) channels. A predictive theoretical...
