title: RAxML_bipartitions.consensusPhylogenomic analyses in the complex Neotropical subfamily Corydoradinae (Siluriformes: Callichthyidae) with a new classification based on morphological and molecular data

description: T he family Callichthyidae, which comprises the subfamilies Corydoradinae and Callichthyinae, represents one of the largest families within the Siluriformes. Corydoradinae, the largest subfamily of Callichthyidae, alone accounts for &gt;200 valid species, with new species being described frequently. This subfamily holds significant popularity among catfish enthusiasts worldwide, mainly because Corydoras are small, peaceful, and colourful fishes. Recognizing the existence of polyphyletic groups within Corydoradinae, the aim of this study was to construct a new phylogen etic hypothesis using genomic data (ultraconserved elements) and to re-evaluate the synonymized genera using the most recent morphological data. Our results supported the monophyly of Corydoradinae and identified seven distinct groups of species, each one with an associated pre available generic name. These genera, namely Corydoras, Aspidoras, Scleromystax, Gastrodermus (resurrected), Osteogaster (resurrected), Brochis (resurrected), and Hoplisoma (resurrected), were all validated based on evidence derived from molecular and morphological analyses. A taxo nomic key for the Corydoradinae genera is provided.

title: Semiconductor Heterostructures: Interfacing with Magnetism and Superconductivity

description: III-V semiconductors have been widely studied since the 1960’s and their physical properties, as well as, their synthesis is fairly well understood. These systems can also host more modern topological characteristics and can be used to study non-s-wave superconductivity. This makes this class of materials a highly attractive platform for studying different types of physics through either doping these semiconductors directly or through interfacing with other materials. This thesis makes use of both of these methods to study the effects of magnetic doping and to study the impact on an interfaced superconductor. To investigate the impact of magnetic doping, we show experiments on Mn doped
InAs/GaSb and use Shubnikov de Hass oscillations to extract the magnetic exchange constant. We find that the introduction of Mn into the InAs/GaSb allow for the tuning of the fermi level and alters the band alignment of the bilayer system. Interestingly, we also discover an interface dependence for the existence of anomalous oscillations that correlate with the coexistence of a 2 Degree Electron Gas and a 2 Degree Hole Gas. In order to explore the effects from interfacing with a superconductor, we show measurements done on Sn1-xInxTe grown on III-V semiconductors. In these measurements, we show how the superconducting critical temperature of Sn1-xInxTe can betuned though interfacing with tertiary III-V semiconductors. We also show a sample that breaks the Pauli limit for the upper critical magnetic field, which could indicate a superconducting pairing symmetry beyond typical s-wave pairing. This thesis shows how material properties can be changed through the consideration of interfaces. The techniques that are involved in studying interfaces can vary based on the type of physics that manifests as a result. The techniques used and developed within this thesis can be used as a basis for further interface focused projects using III-V semiconductors as a platform of study.

title: Search for the Lepton-Flavor Violating Decay of the Higgs Boson and Additional Higgs Bosons in the Electron-Muon Final State

description: This dissertation presents a search for the lepton-flavor violating decay of the Higgs boson and potential additional Higgs bosons with a mass of 110-160 GeV to a pair of oppositely-charged electron-muon. A proton-proton collision data set at a center-of-mass energy of 13 TeV and an integrated luminosity of 138 fb^-1 collected by the Compact Muon Solenoid experiment at the Large Hadron Collider is used. No excess is observed for the Higgs boson. The observed (expected) upper limit on the branching fraction is determined to be 4.4 (4.7) x 10^-5 at 95% confidence level, the most stringent direct limit thus far. For the additional Higgs boson, the largest excess of events over the expected background is observed at an electron-muon invariant mass of around 146 GeV. The local (global) significance of the excess is 3.8 (2.8) standard deviations in the full mass range of the search. This is the first direct search for additional Higgs bosons with a mass of 110-160 GeV in the electron-muon final state.

title: Supersonic Cluster Beam Deposition of Nanoalloys and Bimetallic Nanostructures for Enhanced Oxygen Evolution Reaction

description: Making Hydrogen synthesized by electrochemistry the best alternative to fossil fuels requires to overcome the slow kinetic of the oxygen evolution reaction (OER) in the electrochemical cell. The state-of-the-art OER electrocatalysts, based on nanoalloyed materials, face two main challenges still hindering the large-scale development: 1) the optimization of the electrode morphology and 2) the achievement of the catalyst stability under industrial prolonged activity. This PhD dissertation tackles both issues by synthesizing, through Supersonic Cluster Beam Deposition, a novel NiFe nanoalloyed electrode of controllable morphology, applied as OER catalyst under prolonged operational conditions. An in-depth physical, chemical and electrochemical characterization is carried out through several microscopy and spectroscopy techniques. The electrochemical characterization is carried out as a function of the NiFe morphology and mass loading within the 10 ng/cm2 – 30 ug/cm2 range. The data reveal that an excellent OER catalytic activity can be achieved, while the optimization of the NiFe morphology is accomplished by minimizing the NiFe mass loading without affecting the electrochemical efficiency. Conversely a procedure to stabilize the catalytic response in prolonged OER operation is proposed and correlated to chemical and morphological transformation of the electrode. These findings represent a crucial step towards the synthesis of affordable OER electrocatalysts in large-scale industrial applications. In the physical and chemical characterization of the NiFe films, the optical spectroscopy plays a crucial role. To this aim a new home-made software for the quantitative analysis of the UV-VIS-NIR optical spectra is developed and also applied to other Au and Ag based plasmonic system. In this framework, an advanced fabrication technique (nanoimprinting lithography and dynamic templating combined with liquid/solid interface growth) is employed to synthesize arrays of Au crystalline structures with an enhanced optical and plasmonic response. The investigation of such synthesis method and the design of specific plasmonic structures, combined with a through optical characterization, represent an advancement in a wide range of applications including sensing and nanoelectronics.

title: Development of fIREBall for Coincidence Measurements

description: The nature of 0+ states in deformed nuclei has been an open question in nuclear structure studies. This question arose from the viability of superimposed vibrations on a deformed nucleus. E0 transitions have long been considered the final piece needed to answer this question. However, there is a lack of experimental data due to the difficulty observing 0+ states. Given the reactions, spectroscopy, and E0 transitions that are required, the challenge revolves around the need to single out the conversion electrons from other particles that are emitted during de-excitation. The resulting spectra are also complex, due to the high density of levels in heavy nuclei, making it difficult to extract the necessary information from singles measurements. To overcome these challenges, recent developments have been aimed towards using coincidence measurements. 

This work aimed to measure E0 transitions in 156Gd through coincidence measurements. A significant amount of technical developmental work was done to improve the electron detection efficiency to increase the odds of observing coincidences. ICEBall (Internal Conversion Electron Ball) was transformed into the new fIREBall (fInternal conveRsion Electron Ball) to improve electron detection efficiency. An innovative method involving simulations was used to optimize the geometries for the magnet filters used in the spectrometer. The array of six Si(Li) detectors inside the spectrometer was also replaced with six new, thicker Si(Li) detectors. The simulations were successfully used to design magnet shapes that improved the absolute efficiency from 2.8% to 5.3% at 482 keV for a single filter and detector pair. However, the new detectors were found to be 20% less efficient due to improper Li-drifting near the edges.

Additional technical work was done to improve the rest of the experimental setup. This includes the development of a new method of fabricating pure thin metal foil targets, the commissioning of a new pair of Bismuth Germanate (BGO) Compton Suppression shields, and the implementation of a new data (DAQ) system for all future fIREBall experiments. Finally, a new program, TROPIC (TRansitiOn ProbabIlity Calculator), was created to provide a modern and efficient method to extract B(pl) values from lifetime measurements. 

Commissioning experiments with the 154Sm(a, 2n)156Gd reaction were done to see if the improvements allowed for better coincidence measurements. The viability and validity of the concept was confirmed by K/(L+M) ratios in the low energy range that were in good agreement with theoretical calculations from BrICC. Unfortunately, the sub-optimal condition of the new Si(Li) detectors resulted in the electron count being only 30% of the ? ray count. This resulted in sparse statistics in the high energy range, where the E0 transitions for 156Gd are, precluding any confirmation on the observance of E0 transitions. It is clear that detectors that are of sufficient quality and quantity are absolutely necessary in order for coincidence measurements to be a viable method for observing E0 transitions.

title: Development of Complete <em>ex vacuo</em> Ion Beam Analysis and its Application to Indoor and Outdoor Environment Dust Samples

description: The escalating duration of time spent indoors over recent decades has resulted in prolonged exposure to environmental pollutants within indoor spaces. While efforts to measure indoor pollutants have been underway, most existing methods are characterized by substantial expenses or protracted measurement durations. This dissertation addresses these challenges by proposing a method suitable for assessing both indoor and outdoor dusts and soils, thereby facilitating widespread screening of indoor environments for potential pollutants.

The devised approach to achieve this objective is the ex vacuo Ion Beam Analysis (IBA), characterized by its rapid measurement time of 3 minutes and cost-effectiveness attributed to the straightforward sample preparation required. This methodology has been applied to three distinct sample sets, encompassing an XRF vacuum dust study conducted in Marion County, Indiana, a Reddit vacuum dust survey spanning the state of Indiana, and a road dust collection initiative from Lake County, Indiana.

In addition to the innovative measurement technique, the sampling approach employed in the Reddit survey involved harnessing the collective efforts of online volunteers who submitted their vacuum dust samples for analysis. This presents an opportunity to expand the realm of citizen science, concurrently mitigating sample collection costs by necessitating only the purchase of postage and envelopes as opposed to physically visiting each collection site.
