  1. 1. Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

    Författare :Jasper Immink; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal phase behavior; microgel; binary mixture; colloidal gel; sequential gelation; patchy particle; binary crystal; crystal-to-crystal transition;

    Sammanfattning : Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction.

    Sammanfattning : Pulmonary route has been used as a source of drug delivery to lungs for centuries. Drugformulation decides the type of inhaler devices such as pressurized metered-dose inhalers(pMDIs), nebulizers and dry powder inhalers (DPIs). LÄS MER

  5. 4. Exploring binary mixtures of protic ionic liquids– Interactions, dynamics, and non-ideal behavior

    Författare :Negin Yaghini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nano-confinement; protic ionic liquid; molecular interactions; binary system;

    Sammanfattning : Ionic liquids are organic salts that melt at low temperatures and provide a set of properties beneficial for diverse applications. These properties include good thermal stability, high ionic conductivity, low volatility and non-flammability. LÄS MER

  7. 5. Proton conducting ionic liquids-Binary mixtures and structural modifications

    Författare :Iqbaal Abdurrokhman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanostructure; hydrogen bonds; Protic ionic liquids; fuel cell;

    Sammanfattning : Proton conduction is a phenomenon of fundamental importance for biological and chemical systems, such as in photosynthesis and aerobic respiration. Proton conduction is also key in the proton exchange membrane fuel cell, a clean electrochemical device that converts chemical into electrical energy. LÄS MER
