Vacuum insulation panel core materials and modelling the thermal conductivity of granular materials" (2015). Graduate Theses and Dissertations. Paper 14780.
Rheological behavior of aqueous suspensions containing nanometer-sized powders is of relevance to many branches of industry. Unusually high viscosities observed for suspensions of nanoparticles compared to those of micron size powders cannot be explained by current viscosity models. Formation of so-called hydration layer on alumina nanoparticles in water… (More)
The laws of the United States and of the State of Iowa provide for resident academic instruction, research, and extension education, and for the management of Iowa State University of Science and Technology. The university and two other state educational institutions of higher learning are governed by the Board of Regents, State of Iowa, which is composed… (More)
We are continuing our efforts in proof-of-concept of a new high temperature alloy based on our previous efforts on computational materials discovery. The architectural framework for our material " s design is a refractory base metal with a high temperature intermetallic which provides both high temperature strength and a source of oxidatively stable… (More)
Finding prospective high temperature materials for use in advanced coal-fired plants has proven to be an extreme materials challenge. We propose a new methodlogy to predict alloys with high melting temperatures by estimating their formation enthalpies. The Miedema's approach has been extended to ternary systems using an energy minimization scheme. The power… (More)
