  1. 1. Towards a responsive functional material: Modification of porosity and grafting of poly(N-isopropylacrylamide) in mesoporous silica SBA-15

    Författare :Nina Reichhardt; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mesoporous silica; SBA-15; intrawall pores; PNIPAAM; lower critical solution temperature; water sorption calorimetry; gas sorption;

    Sammanfattning : Mesoporous silica materials, such as SBA-15, have potential as biocompatible carriers for pharmaceutical applications as well as mini-reactors in e.g. catalysis. This potential arises from their well-defined porous structure on the nanometre scale accompanied by a high internal surface area (800 - 1000 m2/g). LÄS MER

  3. 2. Mesoporous Silica SBA-15 - Formation, Modification and Application

    Författare :Tomas Kjellman; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SBA-15; Mesoporous Silica; Intrawall pores; Colloidal Stability; Drug release; Deposition;

    Sammanfattning : Several aspects related to the mesoporous silica material SBA-15 have been studied through the use of a wide range of experimental techniques, including low voltage high-resolution scanning electron microscopy, small angle X-ray scattering and nitrogen sorption. This work contains three parts, which are in many ways overlapping. LÄS MER
