COMPUTATIONAL INVESTIGATION OF TURBULENT BLOOD FLOW AND HEMOLYSIS IN BIOMEDICAL DEVICES
(2015-12-18)
Turbulent blood flow in medical devices contributes to blood trauma, yet the exact mechanism(s) have not been fully elucidated. Local turbulent stresses, viscous stresses, and the rate of dissipation of the turbulent kinetic ...
CHARACTERIZATION OF POLYETHOXYLATED ALKYL PHENOLS WITH A HIGH DEGREE OF ETHOXYLATION AT THE SOLID-LIQUID INTERFACE
(2016-05)
Fully characterizing the behavior of a surfactant, from the mechanism of adsorption to the formation of micelles, is vital when taking the surfactant out of the lab and into the real world. The critical micelle concentration, ...
Diffusional constraints implications in C-C reactions over Brønsted acid sites
(2023)
The constrained pore structure and catalytic properties of zeolites can occasionally offer diffusion limitations to a molecule during the course of a chemical reaction. These constraints significantly impact the rate of ...
Simulation of small-angle scattering patterns via a Monte-Carlo technique.
(2000)
Small angle scattering (SAS) is sensitive to morphology on the nanometer length scale but data analysis can be somewhat difficult. Analytical models exist to analyze SAS data but some morphologies do not have realistic ...
Properties of Noble Metal Nanoparticles: Molecular Dynamics and Density Functional Theory Studies
(2010)
Supported metal nanoparticles play an important role in heterogeneous catalysis. In recent years, carbon nanotubes, because of their unique properties, have drawn interest as supports. The structural and dynamic properties ...
The use of colloid-enhanced ultrafiltration to remove organic pollutants and metal ions from wastewater generated from the pulp and paper industry.
(2003)
Colloid-enhanced ultrafiltration (CEUF) is a surfactant based separation technique which requires low energy and produces high rejection with reasonable flux rates. In micellar-enhanced ultrafiltration (MEUF), surfactant ...
MULTISCALE SIMULATIONS OF HEAT TRANSFER IN NANOCOMPOSITES
(2012)
The field of nanotechnology has been expanded by the discovery of fullerenes and carbon nanotubes (CNTs) in the 20th century. Geim and Novoselov won the Nobel prize in 2010 for their work on graphene sheets (GSs). Those ...
Study of transport phenomena in turbulent channel flows using Direct Numerical Simulation and Lagrangian Scalar Tracking
(2016-05-13)
In this study, Direct Numerical Simulation (DNS) and Lagrangian Scalar Tracking (LST) method are used simultaneously to study fundamental transport phenomena in turbulent channel flows. Area of study covers drag reduction ...
Continuous reduction of nickel and cobalt from ammoniacal sulfate solutions by hydrogen in a tubular reactor /
(1983)
Ammoniacal nickel sulfate solution treated with ferrous sulfate (nucleating agent) was contacted with hydrogen in a continuous countercurrent tubular reactor. Bottom products (liquid-solid) and overflow products (gas-liquid) ...
Zeolite-Catalyzed Surface Chemistry in Alkane Isomerization and Methanol-to-Hydrocarbons Catalysis
(2013)
Zeolite catalysts are eminently vital to production of liquid transportation fuels and commodity chemicals. In each particular application, the surface reactions catalyzed by the zeolite determine its productivity. It is ...
