2. Acidification trends in Swedish lakes : an assessment of past water chemistry conditions using lake sediments
Abstract : This thesis presents temporal perspectives of lake acidification in Sweden. Sediment records have been used to study timing, trends and causes of acidification, and two different techniques for assessing past lake-water acidity are presented. READ MORE

3. HNO3-Induced Atmospheric Corrosion of Copper, Zinc and Carbon Steel
Abstract : The role of nitric acid (HNO3) on the atmospheric corrosion of metals has so far received little or no attention. However, the last decades of decreasing sulphur dioxide (SO2) levels and unchanged HNO3 levels in many industrialized countries have resulted in an increased interest in possible HNO3-induced atmospheric corrosion effects.

5. Hydrodeoxygenation (HDO) catalysts Characterization, reaction and deactivation studies
Abstract : Production of biomass derived fuels such as renewable diesel, are primarily intended to reduce the reliance of the conventional engines on petroleum fuels as well as the emission of CO2 from fossil hydrocarbons. Hydrodeoxygenation (HDO) is a powerful technique that has been regularly used in the fuel upgrading processes. READ MORE
