Priye, Aashish (2015-03-27)The ability of convective flows in micro-scale confinement to direct chemical processes along accelerated kinetic pathways has been recognized for some time. However, practical applications have been slow to emerge because ...
-
Ding, Yufang (2019-01-15)Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease in western countries and characterized by a spectrum of liver injuries ranging from simple steatosis to steatohepatitis (NASH) with or ...
-
Rajeeva Pandian, Navaneeth Krishna (2021-08-25)Venous valves are anatomical structures in the veins, small and large, that help in the unidirectional flow of blood towards the heart. Unwanted clot (thrombus) formation at these valves and its subsequent complications ...
-
Varela Guerrero, Victor (2012-07-16)Global climate change is one of the most challenging problems that human beings are facing. The large anthropogenic emission of CO2 in the atmosphere is one of the major causes for the climate change. Coal-fired power ...
-
Dominguez Ontiveros, Elvis Efren (2011-08-08)Experiments investigating complex flows in rod bundles with spacer grids that have mixing devices (such as flow mixing vanes) have mostly been performed using single-point measurements. Although these measurements allow ...
-
Doria, Steven Michael (2023-01-23)Point of care (POC) instruments are a growing class of diagnostic tools designed for use in low resource settings, such as population screening, and rapid testing in traditional healthcare settings. The current state of ...
-
Yost, Jarad Wilker (2020-04-08)Microfluidic PCR is one of the most common and widely used sample preparation techniques. Most heating methods for microfluidic PCR are heated in one of two ways: (1) the reaction is pumped between different boundary-heating ...
-
Hirunsit, Pussana (2011-10-21)Pt-based alloy surfaces are used to catalyze the electrochemical oxygen reduction reaction (ORR), where molecular oxygen is converted into water on fuel cell electrodes. In this work, we address challenges due to the cost ...
-
Bhat, Bhargavi Sripathi (2020-11-18)The study of supramolecular structures has been gaining a lot of momentum in recent years due to their potential application in several interesting areas such as medicine, catalysis, energy, oil and gas, etc. Hydraulic ...
-
Agrawal, Shilpa (Texas A&M University, 2005-08-29)Photo-polymerized cross-linked polyacrylamide gels are becoming increasingly important for use in micro-fabricated DNA electrophoresis systems because they allow a concentrated sieving matrix to be precisely positioned at ...
-
Islam, Md Nazibul (2023-08-09)The recent outbreak of SARS-COVID-2 virus has emphasized the necessity for low-cost, portable, rapid, and sensitive biomolecule handling and detection systems for effective monitoring and management of pandemics and other ...
-
Ravisankar, Vijay (2016-11-03)The release of corroded alumina during a Loss of Coolant Accident (LOCA) leads to deposition of these particles on the strainer, which consequently introduces a head loss that can cause shutdown of the cooling system. Salts ...
-
Delchini, Marc Olivier (2011-08-08)In this study, the impact of various flow models is assessed under free and forced convection: compressible versus incompressible models for a Pressurized Water Reactor, and Darcy's law vs full momentum equation for High ...
-
King, Stephen Dean (2020-05-04)The work presented in this thesis includes experimental measurements of pressure drop and velocity measurements within a packed bed of smooth spheres gathered through particle image velocimetry (PIV) techniques for the ...
-
Pressure Field Measurements in a Helical Coil Steam Generator Model Using Pressure Sensitive Paint Porter, Garland Alec (2020-05-02)Helical coil heat exchangers are types of tube and shell heat exchangers that have been implemented in processing plants, oil and gas, and refrigeration. Currently several designs have been proposed for next generation ...
-
Yang, You-Hao (2012-10-19)Thin films with the ability to impart oxygen and other types of gas barrier are crucial to commercial packaging applications. Commodity polymers, such as polyethylene (PE), polycarbonate (PC) and polyethylene terephthalate ...
-
Yu, Xiao (2012-07-16)Hydrophobic drug paclitaxel nanoparticles (PAX NPs) and pH sensitive hydrogels were prepared in this study to build a colon targeting nanoparticle based drug delivery system for oral administration. Negative charged PAX ...
-
Lee, Chin-An (2018-08-08)Protease activities provide essential physiological functions in the human body, such as food absorption, and abnormal protease activities can lead to severe diseases. In order to diagnose and monitor these diseases, it ...
-
Rhee, Kathy Yeonjoo (2022-04-04)All major processes in living systems depend on energy sources. In bacteria undergoing cellular respiration, the central source of energy is the proton motive force (PMF). In addition to ATP synthesis, the PMF directly ...
