2. 1. Immunomodulatory Properties of 2-Hydroxyethyl Methacrylate

   Author : Jennie Andersson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 2-Hydroxyethyl Methacrylate; Granulocyte; Respiratory burst; Immunoglobulin; B cell; Interleukin; Mouse;

   Abstract : Immunomodulatory Properties of 2-Hydroxyethyl Methacrylate Jennie Andersson Department of Oral Microbiology and Immunology, Institute of Odontology, Sahlgrenska Academy, University of Gothenburg Professionals working in dentistry have reported adverse effects, such as allergic contact dermatitis, following exposure to 2-hydroxyethyl methacrylate (HEMA). Furthermore unpolymerized HEMA monomers leaking from cured fillings can reach the dental pulp, where HEMA could come into contact with leukocytes. READ MORE

4. 2. Strategies for building polymers from renewable sources : Using prepolymers from steam treatment of wood and monomers from fermentation of agricultural products

   Author : Margaretha Söderqvist Lindblad; KTH; []
   Keywords : renewable sources; biodegradable polymers; hemicellulose; 2-hydroxyethyl methacrylate; modification of hemicellulose; methacrylation reaction; rheology measurements; dynamic-mechanical behavior; 1; 3-propanediol; 1; 4-cyclohexanedimethanol; succinic ac;

   Abstract : A strategic research area today is development of polymericproducts made from renewable sources. The ways of utilizingrenewable sources studied in this thesis are using 1)prepolymers obtained by steam treatment of wood and 2) monomersobtainable by fermentation of agricultural products.

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; persistence; bioaccumulation; toxicity; biodegradation; biotransformation; PBT; read across; soil; earthworm; zebrafish; copepod; BFRs; polybrominated diphenyl ethers; tetrabromobisphenol A; hexabromocyclododecane; hexabromobenzene; 2; 4; 6-tribromophenol; tetrabromobisphenol A; 2-hydroxyethyl ether; 1; 2-dibromo-4- 1; 2-dibromoethyl cyclohexane; Environmental chemistry; Miljökemi;

   Abstract : Brominated flame retardants (BFRs) are chemicals used in e.g. electronic equipment, textiles and plastics for the prevention of fire. Over recent decades, concern has been raised regarding some heavily used BFRs, since the levels in the environment have been increasing. READ MORE

6. 4. Exploring the Use of Terpenes as Renewable Polymer Feedstock

   Author : Arne Stamm; Per-Olof Syrén; Nico Bruns; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-based polymers; terpenes; α-pinene; sobrerol methacrylate SobMA ; verbanone lactone VaL ; 1- 1 -hydroxyethyl -3- 2 -hydroxyethyl -2; 2- dimethylcyclobutane HHDC .; Kemi; Chemistry;

   Abstract : Rising environmental awareness and responsibility has increased the demand for novel,  bio-based  sustainable  materials.  Therefore,  there  is  an  extensive  need  to research  and  develop  closed-loop  materials  from  novel  feedstocks  that  can  be generated  using  benign,  environmentally  friendly  synthetic  routes.

7. 5. Regioselective Heck Coupling Reactions : Focus on Green Chemistry

   Author : Karl S. A. Vallin; Anders Hallberg; Mats Larhed; Walter Cabri; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Medicinal Chemistry; läkemedelskemi;

   Abstract : Carbon-carbon bond formation reactions are among the most important processes in chemistry, as they represent key steps in the synthesis of more complex molecules from simple precursors. This thesis describes mainly the development of novel regioselective applications of the mild and versatile palladium-catalyzed carbon-carbon coupling method, commonly known as the Heck reaction.
