1. 1. Microbial production of chemical building blocks from lignin

   University essay from Lunds universitet/Teknisk mikrobiologi

   Author : Kevin Bertilsson; [2024]
   Keywords : Lignin; Green plastic; Vanillin; Microbial production; Applied microbiology; Biology and Life Sciences;

   Abstract : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. READ MORE

3. 2. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Douglas Björkengren; [2023]
   Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

4. 3. Synthesis and analysis of potential metabolites of ADB-5´Br-BUTINACA

   University essay from Linköpings universitet/Kemi

   Author : Alaa Malekshahineia; [2023]
   Keywords : metabolites; NPS; synthetic cannabinoids;

   Abstract : In recent years, there has been a rise in the use of New Psychoactive Substances (NPS) that mimic the effects of controlled drugs and licensed medicines, which have become a significant public health concern globally. Synthetic cannabinoids, a rapidly expanding category of NPS, with much higher potency and binding affinity to the cannabinoid receptors than ∆9-tetrahydrocannabinol (THC), have led to serious psychiatric complications and other adverse effects.

5. 4. 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.

6. 5. Exploring Regioselective 5N-acylation of Neuraminic acid

   University essay from Lunds universitet/Kemiska institutionen

   Author : Simon Hans Lilje; [2022]
   Keywords : acylation; amide; antibacterial drugs; regioselective deprotection; sialic acid; organic chemistry; Chemistry;

   Abstract : In this project, a regioselective method to deprotect and acylate the amide on C5 of sialic acid is explored. Sialic acid is one of the most complex monosaccharides and is an important ligand in many higher organisms in intercellular cell communication. The most prominent example is related to the immune system. READ MORE
