6. Development and Application of Methods based on DOAS and FTIR Absorption Spectroscopy for Atmospheric Research
Sammanfattning : Over the past decades concern about the environmental impact on our atmosphere from human activities has been constantly increasing. From the recognition of local industrial pollution in the first part of this century, over regional scale problems related to urbanisation and growth of traffic systems to global environmental problems such as climate change and stratospheric ozone depletion.

7. Holistic evaluation and testing of coil coatings
Sammanfattning : Coil coatings are durable organic coatings used to protect metal sheets from corrosion and improve their aesthetic properties. Because of their extensive use, coil coatings have long been of interest for industrial and academic researchers. LÄS MER
8. Structure and dynamics of amyloid-beta oligomers
Sammanfattning : Alzheimer's disease (AD) is the most common cause of dementia, affects tens of millions of people all over the world and inflicts huge socioeconomic costs on the societies. AD is a neurodegenerative disease; it progresses over time and is highly debilitating at the advanced stages. LÄS MER
9. Early Hydration of Portland Cement
Sammanfattning : The production of cement is responsible forapproximately 7 % of the total CO2 emissions caused by man. To compensate for high energyconsumption and CO2 emission, thus making the utilization of concrete more sustainable,several strategies can be used. LÄS MER
10. (In-)Stability of LiPF6-based Electrolytes for Lithium-ion Batteries
Sammanfattning : The state of the art lithium-ion batteries present in most portable electronics consist of the salt LiPF6, organic solvents such as ethylene carbonate and dimethyl carbonate (commonly seen as EC/DMC), and finally, a number of additives - all components enclosed by different kinds of electrode chemistries.Despite their commercial success, all LiPF6 based electrolytes suffer from poor chemical and thermal stability.
