An Open-Source, Automated Chemical Vapor Deposition System For The Production Of 2d Materials, Dale Brown
An Open-Source, Automated Chemical Vapor Deposition System For The Production Of 2d Materials, Dale Brown
Boise State University Theses and Dissertations
While interest in two-dimensional materials has exploded in recent years, the high cost of chemical vapor deposition (CVD) systems can act as a barrier to entry for some researchers interested in studying these materials. This thesis presents an open-source design for an automated CVD that can be built for a fraction of the cost of similarly capable commercial systems and that can easily be customized and expanded.With a CVD built as described,growth of high quality graphene and graphene foam is demonstrated.These results highlight the flexibility of the open-source design in producing a variety of nanomaterials, which are at the forefront …
Electrolyte Optimization Study For Tio2 Nanotube Electrode In Sodium Ion Batteries, Richard Wendel Cutler
Electrolyte Optimization Study For Tio2 Nanotube Electrode In Sodium Ion Batteries, Richard Wendel Cutler
Boise State University Theses and Dissertations
Batteries are ubiquitous in daily life. Sodium-ion batteries have the potential to become inexpensive alternatives to the current market products such as Lithium-ion batteries. TiO2 nanotubes have proven potential as an anode for Na-ion batteries. Electrolytes made by NaClO4 salt and carbonate-based solvents make up commonly used electrolytes in sodium ion battery research. We used electrochemical and physical characterization tests to evaluate the optimum electrolyte for this anode material in the Na system. We determined that the ClO4- ion decomposes at the TiO2 surface and promotes the formation of an unstable solid electrolyte interphase. A …

Plastic Deformation And Effective Strain Hardening Coefficient Of Irradiated Fe-9wt%Cr Ods Alloy By Nano-Indentation And Tem, Corey Kenneth Dolph
Boise State University Theses and Dissertations
The objective of this study is to characterize changes in the yielding, and effective strain hardening coefficient of an oxide dispersion strengthened (ODS) alloy upon exposure to irradiation. It is well known that irradiation produces a supersaturation of defects, which alters the mechanical properties of a material. In order to engineer materials for use in advanced nuclear reactors, the long-term effects of neutron irradiation on mechanical performance must be understood. However, high-dose neutron exposure is often simulated using ion bombardment. Unfortunately, ion irradiation results in a shallow damage layer that prevents traditional bulk mechanical characterization methods from being utilized. A …
Reaction Kinetics Of Rare Earth And Actinide Materials, Brian Jon Jaques
Reaction Kinetics Of Rare Earth And Actinide Materials, Brian Jon Jaques
Boise State University Theses and Dissertations
This dissertation presents the effects of atmosphere, time, and energy input (thermal and mechanical) on the kinetics of gas-solid and solid-solid reactions in systems of dysprosium, uranium, oxygen, and nitrogen. Accordingly, Chapter Two presents a novel synthesis technique used to form DyN via a gas-solid reaction between dysprosium and nitrogen. DyN was rapidly formed through a mechanochemical process in a high energy ball mill at ambient temperatures. The progress of the reaction was quantified using in situ temperature and pressure measurements coupled with microscopy and x-ray diffraction. It was found that the rate of the nitridation reaction is controlled by …
