  1. 1. SBA-15; an investigation into the synthesis solution's effect on formation dynamics and material properties

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Caroline Anderberg Haglund; [2012]
    Nyckelord :Fysikalisk kemi; Chemistry;

    Sammanfattning : The aim of this thesis project was to study the reaction solution’s effect on the formation dynamics and material properties of the mesoporous silica SBA-15. The common synthesis procedure of SBA-15 was applied at 60°C, with 2.5 wt% Pluronic P104 dissolved in 1.6 M hydrochlorid acid. LÄS MER

  3. 2. Investigation of the micelle-to-vesicle transition in mixtures of an anionic and a cationic surfactant: the effect of adding salt

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Josefine Leifsdotter; [2012]
    Nyckelord :SDS; DDAB; NaBr; Static light scattering; cryo-TEM; drug delivery; perforated vesicles; Krafft point;

    Sammanfattning : Catanoinic systems spontaneously form micelles and vesicles, which are self-assembled spherical structures made up by surfactants. In the core of the micelle a drug, or other organic substance, can be kept to stabilize it when placed in an aqueous environment. LÄS MER

  4. 3. Transporttider för vatten i närområdet till en vattentäkt : spårämnesförsök i en isälvsavlagring

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Jonas Enquist; [2006]
    Nyckelord :tracer test; point dilution tests; esker; travel times; water protection areas;

    Sammanfattning : When establishing a groundwater protection area it is of great interest to be able to estimate the transit time of the groundwater from different places of the aquifer to the withdrawal well. These estimates can be uncertain due to heterogeneities in the aquifer. LÄS MER
