Effects of Water Content and Alumino-Silicate Sources on the Structure and Properties of Geopolymers Lizcano, Maricela (2012-10-19)Geopolymers (GPs) are a special class of inorganic polymers with unique properties. Their 3-D amorphous structure and properties are often attributed to SiO2/Al2O3 molar ratios. However; contradictory results reported in ...
-
Park, Seungkyung (2009-05-15)Recent advances in microfluidic technologies have enabled integration of the functional units for biological and chemical analysis onto miniaturized chips, called Labon- a-Chip (LOC). However, the effective manipulation ...
-
Mulloy Jr, John Patrick (2022-06-14)A hybridized Eulerian-Lagrangian solver was built in the open-source computational fluid dynamics code OpenFOAM. This solver was developed as a starting point for higher fidelity combined abrasion-ablation effects modeling ...
-
Saenz Noval, Lina Rocio (2012-02-14)The catalytic N-oxidation of alkylpyridines, a reaction which uses hydrogen peroxide as the oxidizing agent and the water soluble phosphotungstic acid as the catalyst, is a reaction employed in the pharmaceutical industry. ...

Guiza-Arguello, Viviana R. (2013-07-17)The basic principle of tissue engineering is the combination of appropriate cells with biomaterials under conditions that promote and lead to tissue formation. A tissue engineering scaffold is a material that supports cells ...
-
Orea, Daniel (2023-05-04)In this study, an investigation was conducted to characterize the flow behavior of a wrapped screen wick annular heat pipe, using distilled water as the working fluid. To achieve the experimental outcomes, high-resolution ...
-
Alghamdi, Abdulwahab (2011-02-22)The purpose of matrix stimulation in carbonate reservoirs is to bypass damaged zones and increase the effective wellbore area. This can be achieved by creating highly conductive flow channels known as wormholes. A further ...
-
Maher, Blake Rakers (2023-07-26)Advanced reactor and Small Modular Reactor (SMR) systems present a wide range of compelling fluid flow behaviors and complex flow structures. The hemispherical plenum features heavily in high temperature gas cooled reactors ...
-
Muyshondt, Robert Santiago (2021-12-06)Porous media and randomly packed beds are used in a wide variety of engineering applications, including thermal energy storage, modeling of the earth to be drilled in the petroleum industry, heap leaching for precious metal ...
-
Nino Penaloza, Andrea (2013-05-01)Acid fracture conductivity and the effect of key variables in the etching process during acid fracturing can be assessed at the laboratory scale. This is accomplished by using an experimental apparatus that simulates acid ...
-
Li, Ming-Chien (2012-07-16)Two types of fluorescent molecules had been designed and synthesized to improve the analytical infrastructure of capillary electrophoretic separations. First, a hydrophilic version of the permanently cationic acridine-based ...
-
Tzeng, Ping (2015-04-29)Thin films with the ability to control gas permeability are crucial to packaging and purification applications. The addition of impermeable nanoparticles into neat polymers improves barrier/separation properties by creating ...
-
Shirley, Robert Mark (2019-07-03)Since the inception and use of matrix acidizing to stimulate wells, the oil and gas industry has continued to develop new and improved fluids and materials for chemical diversion. However, the effects of chemical diversion ...
-
Vargas, Ethan Lao (2022-04-21)Achieving small feature microelectromechanical system (MEMS) fabrications is currently very challenging when the 3D microstructure is not feasibly compatible with conventional 2D lithography workflow. Here, we present a ...
-
Munoz Pinto, Dany 1981- (2012-07-11)Currently, organ transplant procedures are insufficient to address the needs of the number of patients that suffer of organ failure related disease. In the United States alone, only around 19% of the patients are able to ...
-
Contreras Naranjo, Jose Clemente (2013-11-26)Phenomena occurring when microscopic objects approach planar surfaces are challenging to probe directly because their dynamics cannot be resolved with a sufficiently high spatial/temporal resolution in a non-invasive way, ...
-
Pak, Hyoungmook (2022-04-22)Widespread use and availability of antibiotics has led to infectious and pathogenic bacteria developing antibiotic resistance. Various environmental factors, such as temperature, relative humidity, and wind, can also induce ...
