  • This dissertation will outline solution processable materials and fabrication techniques to manufacture flexible electronic devices from them. Conductive ink formulations and inkjet printing of gold and silver on plastic substrates were examined. Line patterning and mask printing methods were also investigated as a means of selective metal deposition on various flexible substrate materials. These solution-based manufacturing methods provided deposition of silver, gold and copper with a controlled spatial resolution and a very high electrical conductivity.

  • Global competition has caused the US textile industry to modernize and become cost competitive because developing nations have discovered that exporting textile products to the USA is an attractive way to enhance their economic growth. Their low labor costs have pressured domestic producers into replacing labor intensive manufacturing equipment with automated, sophisticated, efficient, hightechnology machinery. The industry has focused on reducing costs, improving quality and developing quick turnaround and response scenarios.

  • Freeform fabrication technology does not require pre-formed mandrels or tooling; instead, it builds physical objects directly from computer graphical data. This type of technology is also known as layer manufacturing, since it constructs the three- dimensional object layer by layer (Jacobs, 1992; Beaman et al., 1997). The technology has proved that it can help to rapidly provide feedback on design concepts, discover inconsistencies in the design, modify the design, and eliminate inconsistency before fabricating the design.

  • Natural photoprotection is provided by structural proteins in the epidermis, particularly keratins and melanin. The amount of melanin and its distribution in cells is genetically regulated, and individuals of darker complexion (skin types IV–VI) are at decreased risk for the development of acute sunburn and cutaneous malignancy. Other forms of photoprotection include clothing and sunscreens. Clothing constructed of tightly woven sun-protective fabrics, irrespective of color, affords substantial protection. Wide-brimmed hats, long sleeves, and trousers all reduce direct exposure.

  • Semiconductor nanostructures are currently one of the largest and most exciting areas in solid state physics. Low-dimensional electron systems (realized in semiconductor quantum structures) are particularly appealing because they allow one to study many-particle effects in reduced dimensions. Inelastic light scattering gives direct access to the elementary excitations of those systems.

  • The electrophoretic deposition (EPD) method was adopted for a fabrication of nanocomposite layers composed of ZnO particles covered by the polythiopene shell in a reduced state. This composite was prepared by oxidative polymerization of thiophene monomer with iron (III) chloride as a catalyst in the presence of ZnO particles. After polymerization, polythiophene in oxidized form was reduced by the extraction in methanol. Electrochemical properties of the obtained composite were measured by cyclic voltammetry and electrochemical impedance spectroscopy.

  • Before the Modular Wetlands Device was installed, the boat wash water was treated by StormCeptor vaults installed in 2003. After installation, bacteria levels still exceeded action levels. Further attempts to reduce bacteria levels resulted in a pilot study conducted by the City of Oceanside. According to the Bacterial Reduction Pilot Program – Oceanside Harbor, XTEX AM antimicrobial fabric filters were installed on the separator vaults in addition to more frequent cleaning of the boat wash out separation vaults and drains as part of the study.
