1. Diffusion, Swelling and Mechanical Properties of Polymers
Abstract : Polymers capability to withstand harmful interactions withdifferent environments can be determined by looking at thetransport and mechanical properties of the material exposed tothe medium. The diffusion of a penetrant in a polymer and itsswelling characteristics can be verified by a simplesorption-desorption experiment followed by methodical analysisof the data. READ MORE

3. Characterization methods and modelling for Li-ion batteries: entropy, impedance, pressure, diffusivity & temperature swings induced aging
Abstract : Lithium-ion batteries are commonly used for energy storage systems, and temperature is one key impact factor on the cell performance and lifetime. In literature, the focus has been on the ambient temperature of the test condition, and there is little discussion about how the temperature swing during cycling affects the battery lifetime.

5. Surface characterization and manipulation of polyampholytic hydrogel coatings
Abstract : This thesis is dedicated to building up fundamental knowledge about polyampholytic hydrogels, which are developed in our group for anti-fouling purposes. Charge-balanced polymers, where positive and negative charges balance each other, have emerged as interesting candidates for many applications in materials science. READ MORE
