Scale-up of Dry Impregnation Processes for Porous Spherical Catalyst Particles in a Rotating Drum: Experiments and Simulations
Maria Silvina Tomassone, Yangyang Shen, Bill Borghard +2
Catalyst impregnation is one of the most crucial steps for preparing industrial catalysts. The inter-particle variability of the impregnated liquid inside the particles significant…
Discrete Element Simulations and Machine Learning for Improving the Performance of Dry Catalyst Continuous Impregnation Processes
Joseph Shovlin, Kuang Liu, Yangyang Shen +3
In this work, discrete element method (DEM) simulations coupled with machine learning are used to study the process of dry impregnation. Our results show that the particle bed cont…
Phase Transitions of Soluble Surfactants at a Liquid-Vapor Interface
M. S. Tomassone, A. Couzis, C. Maldarelli +2
Although medium chain length insoluble amphiphiles are well known to form gaseous and liquid expanded phases on an air/water interface, the situation for the soluble case is less c…
Net Charge on a Noble Gas Atom Adsorbed on a Metallic Surface
A. Widom, M. S. Tomassone, Y. N. Srivastava +1
Adsorbed noble gas atoms donate (on the average) a fraction of an electronic charge to the substrate metal. The effect has been experimentally observed as an adsorptive change in t…
Strongly Temperature Dependent Sliding Friction for a Superconducting Interface
J. B. Sokoloff, M. S. Tomassone, A. Widom
A sudden drop in mechanical friction, between an adsorbed nitrogen monolayer and a lead substrate, occurs when the lead passes through the superconducting transition temperature. W…
Effects of Defects on Friction for a Xe Film Sliding on Ag(111)
M. S. Tomassone, J. B. Sokoloff
The effects of a step defect and a random array of point defects (such as vacancies or substitutional impurities) on the force of friction acting on a xenon monolayer film as it sl…
