Synthesis And Characterization Of A-Site And B-Site Disordered High-Entropy Perovskites, Quinton Wright Apr 2019

Synthesis And Characterization Of A-Site And B-Site Disordered High-Entropy Perovskites, Quinton Wright

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Entropy-stabilized oxides are a new class of ceramic material inspired by high-entropy alloys. In entropy-stabilized oxides, many metallic elements in approximately equal amounts occupy one lattice site. The large number of atom types present in the crystal results in a high degree of disorder in the material. The purpose of this study was to determine if a single-phase samples of two entropy-stabilized oxides could be successfully created through solid-state synthesis. The first of these materials - (Gd0.2La0.2Nd0.2Sm0.2Y0.2)MnO3 - has has 5 A-site elements creating a high degree of disorder. The second of these materials - La(Co0.2Cr0.2Fe0.2Mn0.2Ni0.2)O3 - has 5 B-site …


Developing A Method For Testing Tackiness Of Bituminous Tack Coats, Collin M. Pekol Mr. Apr 2019

Developing A Method For Testing Tackiness Of Bituminous Tack Coats, Collin M. Pekol Mr.

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

In the construction of roads, asphalt is paved in individual layers. To ensure that these layers behave as a single, cohesive unit, a bituminous tack coat is applied between layers. It is critical that this tack coat is adhesive when the hot mix asphalt is applied and non-adhesive otherwise. As of present, there is no standard method for testing the adhesion of bituminous tack coats. A procedure was developed such that a sample tack coat of ~1 mm thickness was allowed to adhere to a temperature-controlled lower plate. After a set time, the upper geometry was lowered until a set …
