  2. 1. Respiratory distress syndrome aspects of inhaled nitric oxide, surfactant and nasal CPAP

    Author : Robert B I Lindwall; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Nitric oxide; Nitrogen dioxide; Pulmonary surfactants; Respiratory therapy; Inhalation exposure; Administration; Inhalation; Continuous Positive Airway Pressure;

    Abstract : Respiratory distress syndrome (RDS) still represents one of the main problems in the treatment of premature infants. Despite the use of surfactant replacement therapy RDS adds to the need for endotracheal intubation and mechanical ventilation (M). READ MORE

  4. 2. Synthesis of Polyhydroxylated Surfactants : Comparison of Surfactant Stereoisomers and Investigation of Haemolytic Activity

    Author : Kristina Neimert-Andersson; Peter Somfai; Krister Holmberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyhydroxy surfactants; Sugar surfactants; Dihydroxylation; Metathesis; Langmuir monolayers; Chiral discrimination; Haemolysis; Organic chemistry; Organisk kemi;

    Abstract : I den här avhandlingen har vi studerat hur man kan göra nya tensider. En tensid är en speciell molekyl som har förmågan att lösa sig i både vatten och olja. Man kan göra följande experiment hemma: Fyll en glasburk till hälften med vatten och tillsätt en droppe matolja. READ MORE

  5. 3. Formation of Block Copolymer and Surfactant Vesicles

    Author : Karin Bryskhe; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; Fysikalisk kemi; biopolymers; Polymer technology; nanoparticles; Lipid; triblock copolymer; surfactants; Nonionic; Vesicles; Formation; Physical chemistry;

    Abstract : In this thesis temperature induced vesicle formation in both a block copolymer system and nonionic surfactant system have been investigated. The block copolymer is a triblock copolymer of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), PEO-PPO-PEO, with the average molecular composition of EO5PO68EO5 and the commercial trade name Pluronic L121 (papers I, II).

  6. 4. The Co-Structure Directing Agent (CSDA) Approach to Mesoporous Silica Formation – Exploring the Assembly Characteristics

    Author : Ruiyu Lin; Fysikalisk kemi; []
    Keywords : mesoporous silica materials; co-structure directing agent; surfactants; mesostructures; scattering; NMR; TEM;

    Abstract : We investigate the formation mechanism responsible for two specific systems of mesoporous silicas formed with the so-called co-structure directing agent (CSDA) route. The synthesis relies on the interactions between silica source (tetraethylorthosilicate, TEOS), surfactants and CSDA. READ MORE

  7. 5. Surface reactivity of metal nanoparticles : - importance of surface active agents and biomolecules from a transformation, mobility and toxicity perspective

    Author : Sara Skoglund; Inger Odnevall Wallinder; Lars Österlund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal nanoparticles; surfactants; metal release; characterization; size distribution; nanotoxicology; risk assessment; Kemi; Chemistry;

    Abstract : Metallic nanoparticles possess unique properties due to their size and are widely used in e.g. consumer products. From this follows a need to identify and assess potential risks of human and environmental exposure. READ MORE
