2. 1. Nanocomposite films for corrosion protection

   Author : Majid Sababi; Jinshan Pan; J.M.C. (Arjan) Mol; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrosion protection; nanocomposite; coating; tool alloy; layer‐by‐layer; polarization; passivity; nanomechanical; topography; Mefp‐ 1; ceria nanoparticle; PAni; UV‐cure; AFM; Peak Force QNM; EIS; SEM; CRM; QCM‐D; ATR‐FTIR;

   Abstract : This thesis describes technical and scientific aspects of new types of composite films/coatings for corrosion protection of carbon steel, composite films with nanometer thickness consisting of mussel adhesive protein (Mefp‐1) and ceria nanoparticles, and polymeric composite coatings with micrometre thickness consisting of conducting polymer and ceria nanoparticles in a UV‐curing polyester acrylate (PEA) resin.The influence of microstructure on corrosion behaviour was studied for a Fe‐Cr‐V‐N alloy containing micro‐sized nitrides with different chemical composition spread in martensitic alloy matrix.

4. 2. Hydrophobic and superhydrophobic coatings for corrosion protection of steel

   Author : Lina Ejenstam; Per M. Claesson; Agne Swerin; Jinshan Pan; Orlando Rojas; KTH; []
   Keywords : Superhydrophobic coating; hydrophobic coating; corrosion protection; contact angles; electrochemical measurements; surface characterization; Kemi; Chemistry;

   Abstract : Since metals in general, and steels in particular, are vital construction materials in our modern society, the corrosion protection of said materials is of great importance, both to ensure safety and to reduce costs associated to corrosion. Previously, chromium (VI) and other harmful substances were effectively used to provide corrosion protection to steel, but since their use was heavily regulated around year 2000, no coating has yet been developed that, in a fully satisfactory manner, replaces their corrosion protective properties.

5. 3. Consumer reported digital immunization records : feasibility, applicability, and public health utility in the Canadian context

   Author : Katherine M Atkinson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: Vaccination is one of the most effective public health interventions of all time. Public health programs collect data on Vaccination Coverage (VC) to determine levels of protection and guide resource allocation for further vaccination campaigns but VC data completeness and utility is a challenge in many settings.

6. 4. On the evolutionary origin of the vertebrate cortex

   Author : Shreyas M Suryanarayana; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The aim of this thesis is to dissect out the minimalistic ancestral neural hardware, which has been conserved in homologue structures of the cerebral cortex and in particular the neocortex, across vertebrates. For this purpose, we utilise the lamprey - a cyclostome (jawless vertebrate), and we compare its anatomical homologue of cortex, the lateral pallium (LPal), in terms of its connectivity, cytoarchitecture and sensory organisation with that of the mammalian neocortex.

7. 5. Targeting glutathione peroxidases : identifying environmental modulators, and screening for novel small molecule inhibitors

   Author : Dorian M. Cheff; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Glutathione peroxidases (GPXs) are a family of selenoproteins that are critical regulators of reactive oxygen species (ROS) in the cell, specifically hydroperoxides like hydrogen peroxide (H2O2). ROS are important for normal cell signaling and are tightly controlled to promote cell growth, proliferation, and survival. READ MORE
