Active Tissue Equivalent Dosimeter: Development of a dosimeter for the International Space Station
Causey, Oliver Ian (2018-07)A Tissue Equivalent Proportional Counter (TEPC) named the Active Tissue Equivalent Dosimeter (ATED) has been developed to measure absorbed dose from radiation on the International Space Station (ISS) and at aviation altitudes ... -
Calculating band structures for organic semiconductors
DeSilva, Charith (2018-04-20)Band structures are very important in understanding the electronic structure of materials; as a result, a good methodology for finding the band structure for electronic materials is extremely important. Organic materials ... -
Charge storage and transport in metal oxide resistive switching devices
Mainali, Punya Prasad (2022-12)Metal oxide resistive switching devices are designed and prepared using atomic layer deposition (ALD) and spin coating methods. The electrical and optical characteristics are studied for their applications in memory, ... -
Density functional theory and time-dependent DFT modeling of organic photovoltaic materials
Dai, Shuo (2017-12)This thesis has aimed to apply Density Functional Theory (DFT) and Time-dependent DFT (TD-DFT) method to design new organic material for small molecule organic photovoltaic (OPV) and molecules for tandem structure solar ... -
Design and Testing of Collimators for Use in Measuring X-ray Attenuation
Panthi, Rajesh (2017-12-01)The main goal of this project was to design and test a set of collimators for use in measuring x-ray attenuation. Two collimators: a primary collimator and a secondary collimator, were built. The primary collimator was ... -
Design, synthesis and characterization of organic semiconductors: From eumelanin-inspired organic materials to novel electron acceptors
Adhikari, Santosh (2018-07)Eumelanin, the black-brown variety of natural pigment melanin, is a fascinating material owing to its multifunctional physicochemical properties, such as broad-band absorption spectrum, antioxidant and free radical scavenging ... -
Determination of the energy spectra of clinical x-ray beams using dose-depth data sets
Panthi, Rajesh (2018-05)A method to determine the energy spectra of clinical x-ray beams based on dose-depth datasets measured in the absorber of known composition and thicknesses was developed, implemented by a computer and tested. An iterative ... -
Discrete-time quantum walk of a Bose-Einstein condensate in momentum space
Dadrasmarani, Siamak (2018-05)Randomness is the essence of many processes in nature and human society. It can provide important insights into phenomena as diverse as disease transmission, financial markets, and signal processing. Quantum randomness is ... -
Dynamics of Cross-Polarization Coupling in a Single Whispering-Gallery Microresonator
Ke, Limu (2019-05-01)In this dissertation, we investigate the dynamics of cross-polarization coupling (CPC) in a single whispering-gallery microresonator, both numerically and experimentally, and develop an independent method of estimating the ... -
Mo-Mo dimer doped ZnS quantum dots and their influence on hybrid halide perovskite heterostructure solar cells
DeGeorge, Zach (2021-12-03)Quantum dots are semiconducting particles on the nanometer scale which exhibit unique size dependent electronic and optical properties due to the quantum confinement phenomenon. Over the past several years colloidal quantum ... -
Multimode input for enhanced dissipative sensing in whispering-gallery microresonators
Rajagopal, Sreekul Raj (2021-05)In this dissertation, we demonstrate a novel sensing technique for enhancing the sensitivity of dip-depth based dissipative sensing. First, we introduce two different sensing techniques (dispersive and dissipative) related ... -
Role of cosmic rays in lightning initiation
Lindy, Nathan Carl (2014-07)From electric field measurements, the maximum electric fields typically found within a thunderstorm are an order of magnitude too weak to initiate a lightning discharge. Relativistic electrons produced in galactic cosmic ... -
Structure and dynamics studies of membrane and non-membrane proteins using NMR and MD simulations
Moktan Tamang, Hem Bahadur (2017-12)The protein structural knowledge is essential in defining molecular recognition rules that power the understanding of basic biological phenomenon. The structures of most proteins are determinable due to advancement in ... -
