Pure And Binary Adsorption Of Methane And Nitrogen On Silicalite, Prahar S. Vaidya Jan 2016

Pure And Binary Adsorption Of Methane And Nitrogen On Silicalite, Prahar S. Vaidya

ETD Archive

Separation processes comprise a large portion of the activity in the chemical and petrochemical industries. For the chemical, petroleum refining, and materials processing industries as a group, separation processes are considered to be critical. Almost all the applications of chemical industries involves mixtures, so innovation in separation technology not only enhances productivity and global competitiveness of U.S. industries, but is also critical for achieving the industrial energy and waste reduction goals. Traditionally, air separation to produce nitrogen and oxygen and to separate nitrogen from methane was practiced by cryogenic distillation, which involved expensive high pressure units and large requirement of …


State Estimation Of Glucose And Insulin Dynamics, Morgan Nicholas Miller Jan 2016

State Estimation Of Glucose And Insulin Dynamics, Morgan Nicholas Miller

ETD Archive

Process simulation and state estimation have very important applications in chemical engineering as well as the biomedical field. Diabetes is a rapidly growing disease in the United States with 29 million people already diagnosed. The estimation of glucose and insulin concentration in patients is necessary in order to effectively treat diabetes. The Bergman Minimal Model is a popular process model that is used to simulate glucose and insulin dynamics. A simulation of this model was created based on estimated parameters for the model from historical data. This thesis investigated the estimation of glucose concentration, insulin concentration, and effect of active …


The Response Of An Ellipsoidal Colloid Particle In An Ac Field, Cornelius Adebowale Obasanjo Jan 2016

The Response Of An Ellipsoidal Colloid Particle In An Ac Field, Cornelius Adebowale Obasanjo

ETD Archive

The quest for new smart materials with engineered properties and desired functionalities has driven scientists into the domain of nanotechnology over the past 30 years. Particles with anisotropic properties as a result of their geometry, chemical patterning or surface functionality have been envisioned as building blocks for advanced materials. By tuning the anisotropic interactions engendered by anisotropic particles, one potentially could manipulate the dynamic pathways for assembly.

The work described in this thesis considers the response of an ellipsoidal colloid particle to a nearby AC electrode polarized at ~0.1 – 4 kV/m and ~0.1 – 3 kHz. The ellipsoidal particle, …
