1. The structure of epsilon-strongly group graded rings
Abstract : The development of a general theory of strongly group graded rings was initiated by Dade, Năstăsescu and Van Oystaeyen in the 1980s, and since then numerous structural results have been established. In this thesis we develop a general theory of so-called (nearly) epsilon-strongly group graded rings which were recently introduced by Nystedt, Öinert and Pinedo and which generalize strongly group graded rings.

3. Design of renewable and functional polyamides and polyhydroxyurethanes with tunable structure-property relationships
Abstract : Redesigning polymeric materials and rethinking their use is imperative in the prospect of a more sustainable future. Critical aspects in this endeavor are the use of renewable monomers to decrease the environmental footprint, implementing green syntheses and production processes and the design for increased recyclability as an end-of-life option to diverge from the generation of plastic waste.

4. The structure of epsilon-strongly graded rings with applications to Leavitt path algebras and Cuntz-Pimsner rings
Abstract : The research field of graded ring theory is a rich area of mathematics with many connections to e.g. the field of operator algebras. In the last 15 years, algebraists and operator algebraists have defined algebraic analogues of important operator algebras. READ MORE

5. Construction of Five-Membered Heterocyclic Compounds via Radical Cyclization
Abstract : This thesis describes how radical cyclization chemistry can be applied for the construction of heterocyclic compounds.In the first part, a series of electron deficient α-phenylselenenylalkenes were prepared via a PhSeCl-addition/HCl-elimination sequence. READ MORE
