Experimental and theoretical investigation of indium phosphide quantum dot growth mechanisms
… to study growth mechanisms of InP QDs from precursor conversion to final nanocrystal formation. As the key experimental platform, a high temperature and high pressure microfluidic system was first applied to study the effect of group V precursor reactivity on the QD growth. High-pressure …

Synthesis and characterization of infrared quantum dots
… This approach led me to explore the role of precursor conversion rate in the growth of III-V QDs and to develop a continuous injection synthesis method that I used to make both III-V and cadmium arsenide QDs. Cadmium arsenide (Cd 3As 2 ) is a narrow gap semiconductor that can form QDs with …

Wildfire Impacts on Water Quality and Implications for Disinfection Byproduct Formation
… though questions remain about changes in the reactivity of fire-affected DOM to form these. Less attention has been paid to unregulated nitrogenous DBPs (N-DBPs), such as haloacetonitriles (HANs), and currently, no studies have investigated the effect of wildfire on haloacetamide (HAM) …

Role of growth inhibitors in nucleation and growth of thin film deposited by chemical vapor deposition in high aspect ratio structures
… the processing conditions, which influence the precursor reactivity with the surface. It is possible to deposit a coating within a deeply recessed feature by chemical vapor deposition. However, when the goal is to obtain a very smooth film of very uniform thickness, there are two main problems: …

Connecting Thermodynamics and Kinetics of Ligand Controlled Colloidal Pd Nanoparticle Synthesis
… bindings to different metal species, i.e., metal precursor and nanoparticle surface, affect the nucleation and growth pathways and rates and connecting the binding thermodynamics to the kinetics quantitatively. The first part of the work (Chapters 4 and 5) is establishing isothermal titration …

Heavy-metal-free colloidal nanocrystal heterostructures – synthetic chemistry and growth mechanisms
… nanocrystals. We first examine how different Cu precursors in the synthesis of colloidal copper sulfide (Cu2-xS) nanocrystals affect the resulting shape and phase. Decreasing aspect ratio in 1D nanorods (eventually transitioning to 2D nanodisks) observed is consistent with the expected effects of …
