  1. 16. HgII uptake in Geobacter sulfurreducens spheroplasts : Thiols’ role in Hg partitioning and methylation

    University essay from Umeå universitet/Kemiska institutionen

    Author : Andreas Eriksson; [2021]
    Keywords : ;

    Abstract : Mercury (Hg) is a naturally occurring trace element and pollutant that is ubiquitous in aquatic ecosystems. All Hg species are hazardous, but methylmercury (MeHg) is the most alarming due to its neurotoxicity, teratogenicity, and bioaccumulation in the food web. READ MORE

  3. 17. Structural studies of Arabidopsis Chloroplast Glutamyl Endopeptidase (CGEP)

    University essay from Uppsala universitet/Molekylär biofysik; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Shruti Ravi; [2021]
    Keywords : structural studies; peptidases;

    Abstract : Peptidases play an essential role in cell machinery by regulating protein turnover and processing synthesized proteins for cellular transport. The chloroplast is a complex organelle present in plants that host several peptidases. READ MORE

  4. 18. Characterisation of Low-Level Jets and their Influence on Low-Level Clouds over the Baltic Sea; Östergarnsholm Observatory, Sweden

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Johan Lundberg; [2021]
    Keywords : Low-level jets; Low-level clouds; LLJs; LLCs; Boundary layer; ABL; CBH; Lidar; Ceilometer; Turbulent intensity; Physics and Astronomy;

    Abstract : In this study, about two years of data from Östergarnsholm in the Baltic Sea are used to analyse offshore low-level clouds (LLCs) influenced by low-level jets (LLJs) in the marine atmospheric boundary layer. The LLJs are passages of strong horizontal winds near the surface and are measured using a Doppler LiDAR, which provides information about the wind speed and wind direction up to 300 meters.

  5. 19. Formulation of nanoemulsions stabilized by cellulose nanocrystals

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Marco Maccagno; [2020]
    Keywords : nanocellulose; hydroxypropyl methilcellulose; Pickering emulsions; microfluidization; drug delivery; nanocellulosa; hydroxipropylmetylcellulosa; Pickering emulsioner; microfluidization; drogleverans;

    Abstract : Cellulose nanocrystals (CNCs) are bio-based nanoparticles with the ability to stabilize oil and water emulsions thanks to their intermediate wettability and nanometric size. These and other types of particle-stabilized emulsions, commonly referred to as Pickering emulsions, are of great academic and industrial interest due to their superior stability against drop coalescence compared to classical surfactant-stabilized emulsions.

  6. 20. Conducting redox polymers for battery applications

    University essay from Uppsala universitet/Strukturkemi

    Author : Mikael Svensson; [2020]
    Keywords : Organic electrode materials; Sustainable battery chemistries; Energy storage;

    Abstract : The near future will put a lot of demand on the increasing need for energy production and storage. Issues regarding the modern-day battery technology’s environmental benignity, safety and cost to sustain such demands thus serve as a huge bottleneck, necessitating the research into alternative electrochemical energy storage solutions.
