Theses and Dissertations
Commercial use of engineered nanomaterials (ENMs; materials in the range of 1-100 nm) has grown dramatically since the discovery of the means to observe, characterize, and controllably synthesize these materials at the end of the 20th century. Today, ENMs represent a global market valued in the trillions of dollars, incorporated into products because of the unique properties they confer, including increased strength, catalytic activity, and interactions with light. In this time, ENMs have also grown from relatively simple first-generation materials, such as Au, Ag, and carbon ENMs, to complex next-generation materials incorporating numerous elements into materials with complex secondary structures, …

Theses and Dissertations
Combining vibrating mesh nebulizers with additional new technologies leads to substantial improvements in pharmaceutical aerosol delivery to the lungs across therapeutic administration methods. In this dissertation, streamlined components, aerosol administration synchronization, and/or Excipient Enhanced Growth (EEG) technologies were utilized to develop and test several novel devices and aerosol delivery systems. The first focus of this work was to improve the poor delivery efficiency, e.g., 3.6% of nominal dose (Dugernier et al. 2017), of aerosolized medication administration to adult human subjects concurrent with high flow nasal cannula (HFNC) therapy, a form of continuous-flow non-invasive ventilation (NIV). The developed Low-Volume Mixer-Heater (LVMH) …
