2. Hyperconjugation in Group 14 Organic Compounds : Design and Property Investigations
Abstract : Nowadays π-conjugated molecules are widely used as materials for devices in organic and molecular electronics. This is due to the ability of such molecules to conduct electricity. However, π-conjugation leads to molecular rigidness and associated lower solubility, which limits possible applications. READ MORE

5. Industrialised house building : fundamental change or business as usual?
Abstract : Criticism concerning quality deficiencies and high production costs for housing has made many construction companies make efforts to improve performance, inspired by ideas from the manufacturing industry and in particular the car industry. This is often referred to as industrialised building. READ MORE
