In this dissertation, I present experimental observations of multiply charged atomic ions (MCAI) generated from interactions of atomic/molecular clusters with moderately intense nanosecond laser pulses. This process is also known as Coulomb explosion (CE) and it has been extensively studied in intense laser fields using ultrashort pulses. Several prevailing theories...
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 aim of this work was to assess the viability of duplex stainless steel 2205 components built via selective laser melting for seawater applications. First, a comprehensive additive manufacturing assessment was done. The duplex stainless steel 2205 components were selectively laser melted from gas atomized powder (D90 <45m) using a...
The advancement of artificial intelligence (AI) has led to transformative developments across multiple sectors, fostering innovation and redefining our interactions with technology. As AI matures and becomes integrated into society, it offers numerous opportunities to address global challenges and revolutionize a wide array of human endeavors. These advances are driven...
The engineering community is increasingly moving towards the design of seismic force-resisting systems that limit post-earthquake damage and reduce downtime to increase urban resiliency. For example, structural spines can be used to provide an elastic load path to impose a more uniform drift distribution with building height, thereby reducing the...
All animals have developed the critical ability to detect, respond to, and detoxify a large array of environmental chemicals and stressors that can cause adverse health effects. Important examples of landmark contaminants around the world are polycyclic aromatic hydrocarbons (PAHs) and dioxins, both of which can act via the aryl...
As one of the most popular data types, the point cloud is widely used in various appli- cations, including computer vision, computer graphics and robotics. The capability to directly measure 3D point clouds is invaluable in those applications as depth information could remove a lot of the segmentation ambiguities in...
The RV Ronald H. Brown traveled a section of tropical Atlantic waters northeast of Barbados during January-February 2020 in an international collaboration effort known as Elucidating the Role of Clouds Circulation Coupling in Climate Campaign (EUREC4A). ATOMIC (Atlantic Trade-wind Ocean–Atmosphere Mesoscale Interaction Campaign) was the US contribution to EUREC4A focused...
Biological hydrogen production from renewable feedstocks was reckoned as a promising method for sustainable energy production. Bioelectrochemical hydrogen production using microbial electrolysis cells (MECs) demonstrated superiorities over the conventional methods for hydrogen production. The introduction of the membrane-less single chamber design further improved the feasibility of MECs for practical application,...
Electrodeposition is a versatile polymer deposition technique to create nano-microscale materials using an electrical field generated from a charged droplet of solution and a grounded collector. Electrospinning or electrospraying can occur during electrodeposition, leading to the creation of nanofibers or bead-like materials depending on the process parameters. Photopolymerization of the...
