1. Platinum-free Electrocatalysts : Design, Synthesis, and Energy Applications
Abstract : Pt is one of the most commonly used catalysts for green energy applications, such as fuel cells, electrolyzers, and dye-sensitized solar cells. Although enormous effort has been put into improving the catalytic activity and minimizing the usage of Pt in the catalysts, the low abundance and high price of Pt still limit the large-scale commercialization of green energy devices and facilities.

2. Free to Choose? : Studies of Opportunity Constraints and the Dynamics of School Segregation
Abstract : As a result of the negative consequences and persistence of school segregation, its causes have received a great deal of scholarly attention across a range of disciplines. However, the existing research has tended to overlook those aspects of the segregation process that lie beyond the choice of the individual. READ MORE

3. Macroscopic Volume and Free Volume of Polymer Blends and Pressure-densified Polymers
Abstract : The macroscopic volume V as a function of pressure P and temperature T is obtained from PVT measurements. PVT data is sensitive to the state of polymers and changes therein. Moreover, PVT data gives access to the free-volume fraction. READ MORE

4. Two Problems in non-linear PDE’s with Phase Transitions
Abstract : This thesis is in the field of non-linear partial differential equations (PDE), focusing on problems which show some type of phase-transition. A single phase Hele-Shaw flow models a Newtoninan fluid which is being injected in the space between two narrowly separated parallel planes. READ MORE

5. Asynchronous Algorithms for Large-Scale Optimization : Analysis and Implementation
Abstract : This thesis proposes and analyzes several first-order methods for convex optimization, designed for parallel implementation in shared and distributed memory architectures. The theoretical focus is on designing algorithms that can run asynchronously, allowing computing nodes to execute their tasks with stale information without jeopardizing convergence to the optimal solution.
