1. Capturing Air Pollutants : Photochemical Adsorption and Degradation of SO2, NO2 and CO2 on Titanium Dioxide
Sammanfattning : Titanium dioxide (TiO2) is a material with many useful properties. It is used most widely as a pigment in white paint, although in technological research it is better known for its ability to catalyze chemical reactions during light absorption. LÄS MER
2. Conversion processes for biofuel production
Sammanfattning : Despite the global positive impacts of soybean-, maize- and sugarcane-based (first-generation) liquid biofuels, several drawbacks pertaining to increased use of agricultural land, causing deforestation in some countries and extensive practice of fertilizers have been observed. As a result, developing advanced (second- and third-generation) liquid biofuels have been identified as better alternatives and are considered to be of great importance in the future. LÄS MER
3. Removal of Micropollutants from Wastewater : evaluation of effect of upgrading ozonation to electro-peroxone
Sammanfattning : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. LÄS MER
4. Pollution problems in reciprocal space : on some sources of error in crystal structure investigations
Sammanfattning : .... LÄS MER
5. Studies on Diesel sprays under non-reacting and reacting conditions
Sammanfattning : Methods for reducing engine-out emissions are urgently needed to mitigate climate change and air pollution. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. LÄS MER
