21. Liquid Crystalline SIloxane Dimers - Advanced Materials with Enhanced Properties
Abstract : The liquid crystal state is a complex state with many kinds of different molecular attractive and repulsive forces that results in various kinds of phases. Since the pioneering works by Vorländer in the early 20th century, liquid crystal research has to a great extent been depending on careful systematic studies of the structure/property relationships in series of similar liquid crystalline materials.

22. Polymer/polymer blends in organic photovoltaic and photodiode devices
Abstract : Organic photovoltaics devices (OPV) have attracted attentions of scientist for their potential as inexpensive, lightweight, flexible and suitable for roll-to-roll production. In recent years, considerable attention has been focused on new acceptor materials, either polymeric or small molecules, to replace the once dominating fullerene derivatives. READ MORE

24. Electrically Conducting Yarns for Electronic Textiles
Abstract : Electronic textiles (e-textiles) present a huge opportunity to incorporate wearable devices into textiles. Electrically conducting yarns and fibers can be utilized to create these e-textiles. For e-textiles to be wearable the development of electrically conducting yarns needs to rely on materials that are neither scares nor toxic. READ MORE
