11. Synthesis of new building blocks for conjugated oligomers
Abstract : This thesis deals with the synthesis of new organicmaterials for electronic applications. Several new ring-formingmethods are employed to construct sulphur heterocycles: Tandemelectrophilic aromatic substitution and acid-catalyzedtransetherification of methoxythiophene, double electrophilicaromatic substitutions with ethane-1, 2-disulphenyl chloride,and also, the reaction of dienes with sulphur dichloride.

13. Recyclable High Performance Thermosets from Biobased Rigid Building Blocks
Abstract : The finite petroleum resources and increasing polymer waste have given rise to concerns associated with the origin and end of life management of polymer materials. Developing biobased and recyclable thermosets is an important and still underexplored part of this process, especially as thermosets also possess inherent recycling issues caused by their crosslinked structure.

14. Exploring different thermoplastics from lignocellulosic building blocks and monomers
Abstract : The need to replace conventional fossil-based plastics is becoming more imperative. As climate change is more visibly affecting our society, employing non-sustainable resources to produce plastics is aggravating the problem. READ MORE

15. Cervical Radiculopathy: A Study With Selective Nerve Root Blocks
Abstract : Cervical radiculopathy is diagnosed by history, clinical examination of the patient and magnetic resonance imaging (MRI) of the cervical spine. In many of the patients undergoing this diagnostic strategy, the nerve root/roots responsible for the radicular pain is difficult to define as clinical examination and MRI investigation does not provide information enough.
