1. 1. Water purification of ibuprofen using whey protein aerogels with and without PNF-structure

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

   Author : Jessica Lyrner Morén; David Jonsson; [2023]
   Keywords : Aerogels; water purification; ibuprofen; protein nanofibrils PNF ; whey protein; attitudes; scientific research; Aerogeler; vattenrening; ibuprofen; protein nanofibriller PNF ; vassleprotein; attityder; naturvetenskaplig forskning;

   Abstract : Clean water, free from pharmaceuticals, is important both for land and water living animals. Protein nanofibrils (PNFs) have already been shown to be a promising candidate for water purification of pharmaceuticals but there is a lack of research that compares PNF materials to non-PNF protein materials for water purification.

3. 2. Biocatalysis in Pickering emulsions

   University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Author : Christine Vera Isabel Schmidt; [2023]
   Keywords : Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

   Abstract : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. READ MORE

4. 3. Evaluation of antimycobacterial molecules' capacity to kill mycobacteria and their toxic effect on human cells.

   University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

   Author : Filippa Henriksson; [2023]
   Keywords : Drug evaluation; In vitro; Mycobacterium tuberculosis complex; REMA; Tuberculosis; In vitro; Mycobacterium tuberculosis complex; REMA; tuberkulos; utvärdering av läkemedel;

   Abstract : Tuberculosis is a fatal airborne disease caused by bacteria from the Mycobacterium tuberculosis complex (MTBC). The incidence of contracting tuberculosis is estimated to be around 10.6 million cases each year. Increased drug resistance among mycobacteria has led to the need to develop new treatments.

5. 4. Synergies of nutrient fractions for fertilization in agriculture

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Linda Adjei; [2022]
   Keywords : Phosphorus; Wastewater; Polonite; molybdenum blue spectrophotometry; Fertilizer; Sunflower; Plant growth;

   Abstract : A few countries are controlling the worlds phosphate reserves and this raw material is depleting at a faster rate. Most of the mined phosphate rock comes from Morocco and the Russia area which has unstable security. Studies shows that about 40% of potash export and 28% of nitrogen and phosphorus (P) fertilizer products comes from the Russia area. READ MORE

6. 5. Towards finding model pollutants for predicting CEC adsorption on biochars : The suitability of using dyes as proxies for CEC removal efficiency to enable wastewater reuse

   University essay from Umeå universitet/Kemiska institutionen

   Author : Alexandra Aveling; [2022]
   Keywords : ;

   Abstract : This study evaluated the use of common dyes as model pollutants for adsorption on biochar. Pollutant removal efficiency of five dyes and three CECs on three different biochars (SWP-550, SWP-700, NDG-SW) was evaluated, using both UV-VIS spectrophotometry and LC-MS/MS, to examine similarities and differences in adsorption performance.
