  1. 1. Living biohybrid systems via in vivo polymerization of thiophene oligomers

    Författare :Gwennaël Dufil; Eleni Stavrinidou; Daniel T Simon; David C. Martin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conducting polymers; Living tissue engineering; In vivo polymerization; Plant Biohybrids; Hydra polyps; Energy storage; Glucose sensor;

    Sammanfattning : Life is the result of a multitude of electrical signals which drives our nervous system but also accomplishes a cascade of electrochemical reactions. In the 18th century, Lucia Galeazzi and Luigi Galvani got the idea to stimulate frog legs with electrodes. LÄS MER

  3. 2. Chemical Pathways for Galactoglucomannan-based Materials

    Författare :Jens Voepel; Ann-Christine Albertsson; Ulrica Edlund; Søren Hvilsted; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polysaccharides; hemicelluloses; galactoglucomannan; renewable; chemical modification; hydrogels; swelling; crosslinking; release; SET-LRP; living polymerization; grafting; hybrid materials; Polymer chemistry; Polymerkemi;

    Sammanfattning : Polysaccharides are an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Due to their natural diversity they can be found in many special applications, e.g. in the biomedical sector and are the major renewable resource for materials of many kinds. LÄS MER

  4. 3. Atom transfer radical polymerization from multifunctional substrates

    Författare :Anna Carlmark; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning : Atom transfer radical polymerization (ATRP) has proven to be a powerful technique to obtain polymers with narrow polydispersities and controlled molecular weight. It also offers control over chain-ends. LÄS MER

  5. 4. Polyhydroxyl and Polyphosphorylcholine functionalized Silica for Hydrophilic interaction liquid Chromatography- Synthesis, characterization and application

    Författare :Nhat Thi Hong Bui; Knut Irgum; Michael Lämmerhofer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrophilic Interaction Chromatography; HILIC; silica; TRIS; acrylamide acrylate; ATRP; iniferter; “controlled living’’ radical polymerization; N; N′-methylenebisacrylamide; MPC; stationary phase; analytisk kemi; Analytical Chemistry;

    Sammanfattning : This thesis focuses on the development of new stationary phases for use in hydrophilic interaction liquid chromatography using TRIS-based and phosphorylcholine typed monomers and porous silica particles as starting substrates. In this thesis, several ways of polymerizing highly hydrophilic mono­mers onto pore surfaces of silica supports are described, based on several “grafting from” schemes. LÄS MER

  7. 5. Fabrication of polymeric microfluidic devices via photocurable liquid monomers

    Författare :Klas Tommy Haraldsson; Mats K. G. Johansson; Ken Carter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photopolymerization; radical photopolymerization; polymerization kinetics; photoinitiation; vinyl ether; maleate; vinyloxy; Polymer chemistry; Polymerkemi;

    Sammanfattning : Microfluidic devices have long been considered an ideal tool for rapid and inexpensive chemical analysis and reactions in areas ranging from point-of-care health to national security applications. However, fabricating microfluidic devices is time consuming, difficult and above all expensive. LÄS MER
