  2. 1. The impact of groundwater chemistry on the stability of bentonite colloids

    Author : Sandra Garcia Garcia; Mats Jonsson; Per Claesson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear chemistry; Kärnkemi;

    Abstract : I det svenska djupförvaret för kärnbränsle ska kompakterad bentonit användas som barriär mellan kopparkapslar med utbränt kärnbränsle och berget. I kontakt med vattenförande sprickor kan bentonitbarriären under vissa omständigheter avge montmorillonitkolloider. READ MORE

  4. 2. Generation, stability and migration of montmorillonite colloids in aqueous systems

    Author : Sandra García García; Mats Jonsson; Tiziana Missana; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; colloid stability; colloid migration; geological disposal; nuclear waste; granitic fractures; ; Environmental chemistry; Miljökemi; Environmental toxicology; Miljötoxikologi; Surface and colloid chemistry; Yt- och kolloidkemi; Nuclear chemistry; Kärnkemi;

    Abstract : In Sweden the encapsulated nuclear waste will be surrounded by compacted bentonite in the granitic host rock. In contact with water-bearing fractures the bentonite barrier may release montmorillonite colloids that may be further transported in groundwater. READ MORE

  5. 3. Programming Blood Cell Fates. Insights from Direct Lineage Conversion and Development

    Author : Sandra Capellera Garcia; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic development; Erythropoiesis; Megakaryopoiesis; Direct Lineage Conversion;

    Abstract : Red blood cells (RBC) and platelets constitute the non-immune branch of the hematopoietic system and are responsible for the vital functions of transporting oxygen to the tissues and clotting blood vessel injuries, respectively. These cells are produced during embryonic development and throughout life through a process called hematopoiesis which is tightly regulated by extrinsic and intrinsic factors. READ MORE

  6. 4. Exploring bis-MPA Based Dendritic Structures in Biomedicine

    Author : Oliver Andrén; Michael Malkoch; Peter Löwenhielm; Sandra Garcia Gallego; Karen Wooley; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; Polymers; antibacterial; self-assembly; Kemi; Chemistry;

    Abstract : In the last decades there has been significant advances in polymer chemistry. New coupling chemistries, polymerization techniques and accelerated approaches enable researches to push the limits of structural control. READ MORE

  7. 5. Evolution of streamlined genomes in ultra-small aquatic bacteria

    Author : Weizhou Zhao; Siv Andersson; Sandra L. Baldauf; Sarahi L Garcia; Karen Lloyd; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; streamlined genome; aquatic bacteria; single cell genomics; metagenomics; evolutionary genomics; salinity; Baltic Sea; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : This thesis investigates the evolutionary processes of streamlined genomes from aquatic bacteria adapting to different salinities, using two groups of ultra-small aquatic bacteria (LD12 Alphaproteobacteria and acI Actinobacteria). Due to difficulties in obtaining pure cultures of these bacteria, culture-free approaches (single-cell genomics and metagenomics) were used to construct and compare genomes, and to study the mechanisms and selective forces of adaptation to freshwater, brackish, and marine ecosystems.
