  2. 16. The influence of quartz and surfactant on immune responses

    Author : Göran Zetterberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : alveolar macrophages; complement receptor 1 and 3; interstitial macrophages; Iysophosphatidylcholine; phospholipids; quartz; rats; receptor expression; surfactant.;

    Abstract : Pulmonary surfactant is a mixture of lipids and proteins that embeds the alveolar cells, has surface tension reducing properties but also influences the immune response. To further investigate this, quartz was used to initiate an inflammatory response in two different models. READ MORE

  4. 17. Self Assembled Monolayers for Quartz Crystal Microbalance based Biosensing

    Author : Annica Myrskog; Bo Liedberg; Sofia Svedhem; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The work in this thesis has been focused on developing surfaces for use in biosensor systems, especially for quartz crystal microbalances. The surfaces were prepared by adsorption of organosulfur molecules onto gold substrates, so called self assembled monolayers (SAMs). READ MORE

  5. 18. Signal Enhancement by Dynamic Polymers in Quartz Crystal Microbalance Applications

    Author : Gunnar Dunér; Olof Ramström; Ian Nicholls; Andra Dedinaite; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Signal enhancement; QCM; polyelectrolytes; hydrogel; iniferter; photopolymerization; dynamic polymers; Chemistry; Kemi;

    Abstract :  This licentiate thesis presents studies of signal enhancement by dynamic polymers in quartz crystal microbalance (QCM) applications. The aim of the study has been to determine the potential for the use of polymers on QCM sensors for signal enhancement in molecular interaction studies. READ MORE

  6. 19. Layer formation on quartz particles during fluidized bed combustion/gasification of woody biomass

    Author : Hanbing He; Christoffer Boman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : The formation of sticky layers on bed particles has been considered as a prerequisite for bed agglomeration in fluidized bed combustion and gasification of woody fuels. In addition, the layer formed makes the bed particle less resistant against fragmentation. The fragments from quartz particles can result in deposition. READ MORE

  7. 20. Reversible Sulfur Reactions in Pre-Equilibrated and Catalytic Self-Screening Dynamic Combinatorial Chemistry Protocols

    Author : Rikard Larsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamic Combinatorial Chemistry; Reversible sulfur reactions; Catalytic self-screening; Carbohydrates; Lectins; Quartz Crystal Microbalance; Organic chemistry; Organisk kemi;

    Abstract : Dynamic Combinatorial Chemistry (DCC) is a recently introduced supramolecular approach to generate dynamically interchanging libraries of compounds. These libraries are made of different building blocks that reversibly interact with one another and spontaneously assemble to encompass all possible combinations. READ MORE
