Assembling magnetic colloidal particles in microfluidic devices
The motivation of this research project is to assemble colloidal particles in microfluidic devices to create intelligent microstructures. We have created three types of novel structures. We have created magnetic chains ...
Additives to Minimize Viscosity Reduction for Borate-Crosslinked Guar under High Pressure
Borate-crosslinked guar is commonly used in hydraulic fracturing. The stimulation process conditions occur at temperatures between100-300 °F and high pressures up to 8000 psi. The viscosity of the borate-crosslinked guar ...
Moving of Magnetic Clusters Driven by an Applied Eccentric Rotational Magnetic Field
Magnetic swimmers have been studied with the purpose of applying them to mimic the motion of organisms in fluids. Clusters formed by self-assembled magnetic particles is one the possible approaches for that purpose. A ...
Coalescence of Model Asphaltene-Stabilized Water-in-Oil Emulsions in Microfluidic Devices
Asphaltene related problems have aroused more and more attention in flow assurance and proved to be fatal with practical examples in both oil production and transportation. Asphaltene-stabilized emulsions generated in the ...
