1. Electronic Structure of π-Conjugated Materials and Their Effect on Organic Photovoltaics
Abstract : The great tunability of structure and electronic properties of π-conjugated organic molecules/polymers combined with other advantages such as light weight and flexibility etc., have made organic-based electronics the focus of an exciting still-growing field of physics and chemistry for more than half a century.

2. Doping and Density of States Engineering for Organic Thermoelectrics
Abstract : Thermoelectric materials can turn temperature differences directly into electricity. To use this to harvest e.g. waste heat with an efficiency that approaches the Carnot efficiency requires a figure of merit ZT larger than 1. READ MORE

3. Charge Sampling Circuits and A/D Converters - Theory and Experiments
Abstract : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. READ MORE

4. Biochemical conversion of biomass to biofuels : pretreatment–detoxification–hydrolysis–fermentation
Abstract : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. READ MORE

5. Co-firing complex biomass in a CFB boiler : ash transformation, corrosion control and materials selection
Abstract : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.
