Quasicrystal Formation, Structure and Indentation Behaviors in Pure Tantalum

Creator:

Wang, Zhengming

Abstract:

Spontaneous quasicrystal (QC) formation has not been observed in pure metals either in computation or in experiments (excluding epitaxial growth of thin atomic layers on a QC template). In this thesis work, dodecagonal QC (DDQC) grains are first discovered to spontaneously form during thermal devitrification of pure tantalum (Ta) metallic...

Masters Thesis
Molecular Dynamics Study of structural Evolution, Tensile Deformation and Nanoindentation of Monatomic Metallic Glasses

Creator:

Chen, Fangzheng

Abstract:

Metallic glasses are attracting tremendous attention because of their fundamental significance and great potential to be used as structural or functional materials in engineering applications. Significant efforts have been devoted to studying their unique properties as well as their disordered nature. Metallic glasses possess much higher strength and elastic strain...

Understanding And Improving The Activity Of Oxygen Evolution Reaction Catalysts In Alkaline And Chloride-Containing Electrolytes

Creator:

Adiga, Prajwal Prakash

Abstract:

Water electrolysis plays a pivotal role in achieving a green hydrogen economy by sourcing electricity from intermittent renewable sources. However, the efficiency of the electrolysis process is limited by the sluggish oxygen evolution reaction (OER) kinetics, whereas the kinetics of the hydrogen evolution reaction (HER) are more facile. This thesis...
