-
(2015-07-29)Department: Chemical EngineeringNanofiber particle/polymer cathode mats, with an average fiber diameter in the 400-600 nm range, were fabricated by electrospinning mixtures of a proton exchange polymer and commercial Pt/C catalyst particles, incorporated ...
-
(2017-01-04)Department: Chemical EngineeringSince their commercial debut in 1991, Li-ion batteries (LIBs) have revolutionized the functionality of portable electronic devices, and the LIB industry continues to grow today due emerging applications such as electric ...
-
(2023-03-24)Department: Chemical EngineeringThe majority of breast cancer patients receive radiation therapy. Although this treatment improves overall outcomes, patients with triple negative breast cancer (TNBC) have a significantly higher risk of distant and ...
-
(2011-04-16)Department: Chemical EngineeringDNA microarrays have become an increasingly important tool for genomic investigations. This work is directed toward establishing methods and surface architectures that allow the monitoring of DNA hybridization and ...
-
(2021-12-01)Department: Chemical EngineeringThe development of cancer occurs when immunosuppression inhibits the naturally occurring process through which the immune system recognizes and eliminates cancer cells (i.e. the cancer-immunity-cycle). While clinically ...
-
(2008-02-22)Department: Chemical EngineeringIn this dissertation we describe a strategy to molecularly optimize the cathode side of a proton exchange membrane fuel cell. This new cathode consists of a porous gold membrane with pores that function as gas diffusion ...
-
(2024-03-11)Department: Chemical EngineeringInspired by swarming motion of living organisms in nature, active particles use the stored energy in the environment to initiate self-propulsion. Successful use of active particles in different applications, including cargo ...
-
(2014-05-27)Department: Chemical EngineeringPhase transitions (i.e. transitions from one state to another) play a crucial role in most natural processes, as well as industrial operations such as evaporation. Molecular simulation has emerged as an important tool for ...
-
(2018-01-11)Department: Chemical EngineeringSkin plays the vital role in human physiology of providing a barrier from the external environment. This barrier function is localized to the lipid matrix of the outermost layer, the stratum corneum. While much has been ...
-
(2010-02-11)Department: Chemical EngineeringCeramic materials in the Al-O-C and Hf-O-C systems were fabricated for electrical or thermal protection applications. AlOxCy films were produced via high-vacuum chemical vapor deposition (CVD) using dimethylaluminum ...
-
(2015-03-26)Department: Chemical EngineeringExtracted from green plants, Photosystem I (PSI) is a nanoscale protein complex that can be incorporated into biohybrid devices to convert solar irradiation into usable power. In previous research, our group has shown that ...
-
(2005-10-24)Department: Chemical EngineeringThe work presented herein focuses on the growth of poly(hydroxyethyl methacrylate) (PHEMA) films on gold by water-accelerated, surface-initiated atom transfer radical polymerization and derivatization of these films with ...
-
(2013-12-04)Department: Chemical EngineeringThere is a compelling clinical need for grafts with initial bone-like mechanical properties that remodel and promote healing of bone defects. This dissertation describes the development and characterization of biodegradable ...
-
(2023-06-01)Department: Chemical EngineeringThe hydrogen/air proton-exchange membrane fuel cell (PEMFC) is a clean and energy-efficient alternative to internal combustion engines in motor vehicles. A significant obstacle to the large-scale commercialization of such ...
-
(2019-03-25)Department: Chemical EngineeringGold nanostars (AuNS) have been utilized in cancer imaging and therapeutics for over decade due to the tunability of their optical resonance in the near-infrared, which allows deep tissue penetration, as well as their ...
-
(2008-08-15)Department: Chemical EngineeringThis work focuses on three different aspects of adsorption equilibrium: the measurement of adsorption equilibrium into the Henry's law region for n-pentane, the calculation of the maximum isosteric heat of adsorption ...
