1. 1. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance

   University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

   Author : Clara Eklund; [2023]
   Keywords : PFAS; Groundwater modeling; FEFLOW; Python; Machine learning; Technology and Engineering;

   Abstract : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. READ MORE

3. 2. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Cecilia Zambelli; [2023]
   Keywords : ;

   Abstract : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

4. 3. Remediation of per- and polyfluoroalkyl substances (PFAS) in contaminated water by sorption to pine- and spruce bark

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Rebecka Ayranci Dahlberg; [2023]
   Keywords : Per- and polyfluoroalkyl substances; sorption; pine bark; spruce bark; ultra-short-chain PFAS; short-and long-chain PFAS; elemental analysis; field-test;

   Abstract : PFAS are anthropogenic substances used in many different industrial operations and products because of their unique properties. Due to their negative impact on human health and environmental bioaccumulative characteristics different authorities have addressed the issue. In Sweden the limit is4 ng/L for four different PFAS in drinking water. READ MORE

5. 4. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials

   University essay from KTH/Materialvetenskap

   Author : Victor Eric Pierre Chartrain; [2023]
   Keywords : Cellulose; Paper; Plasticizer; Mechanical Refining; Cellulosa; Papper; Mjukgörare; mekanisk bearbetning;

   Abstract : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. READ MORE

6. 5. Ammonium and nitrate sorption by biochar

   University essay from SLU/Dept. of Soil and Environment

   Author : Yasser Alrhban; [2023]
   Keywords : biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

   Abstract : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.
