In this work, we systematically explore the effectiveness of optical aberration correction over a wide range of optical depths using the Segmented and Zernike Polynomial bases. We manufacture a set of 16 optical phantom samples consisting of a clear polyester resin substrate embedded with varying concentrations of aluminum oxide (Al₂O₃)...
Water splitting is a green method being researched to produce green hydrogen in order to combat greenhouse gases emitted by the most popular energy source; fossil fuels. Water splitting involves two half reactions: hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Of these two, OER is the bottleneck water...
The Great Recession, which resulted from the burst of housing bubble and officially lasted from December 2007 to June 2009, started as a national recession in the U.S. and then affected countries across the world. Economies reacted differently to this recession and those systems that lost fewer jobs and/or recovered...
As the number of students and faculty involved in online learning in recent decades has increased, we recognize that there is a limited understanding of how learners react, interact, behave, and are served by the various components in the information delivery processes. When learning online without an instructor present in...
This paper is intended to perform cost-benefit, break-even and sensibility analysis of higher-place pond culture of Penaeus vannamei through a case study of a farmer in Zhanjiang City of Guangdong Province, using cost-benefit data about this farmer’s higher-place pond culture of Penaeus vannamei collected from field survey. Major findings of...
The desire to apply short-range wireless communication systems to telemetry sensor networks in a metal-enclosed chamber has prompted this study. This thesis will discuss the design of an infrared (IR) communication system for a wireless low-power, low-data- rate sensor network in a metal enclosure. This design requires an in-depth understanding...
The neutron flux-energy spectral characterization of a Thermo Fisher MP320 deuterium-tritium neutron generator was performed for two shielding configurations, one with substantial moderator between the source and the sample and one without such moderator. The STAYSL PNNL spectral adjustment code was utilized in conjunction with MCNP modelled reference spectra and...
Nonmelanoma skin cancer (NMSC) is the most common malignancy in Caucasian populations. One existing treatment modality for NMSCs is external radiotherapy delivered to the skin cancer tumor by a beta-emitter-containing radioactive skin patch. Alpha emitters, with their higher linear energy transfer than beta particles and shorter range in tissue, make...
Messenger RNA (mRNA) therapy has massive potential to treat various genetic disorders by providing effective proteins to the diseased cells and tissues. Its therapeutic applications include protein replacement, genome editing, and immunotherapy. For successful mRNA treatment, mRNA must be delivered to the cytosol of target cells. One of the leading...
The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...
