2. 1. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

   Author : Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. READ MORE

4. 2. Mesoporous supported lipid bilayers

   Author : Maria Claesson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; FRAP; Lipid bilayer; Mesoporous; AFM; Vesicle; Titania; Silica; QCM-D;

   Abstract : AbstractLipid bilayers are commonly used as simplified model systems of living cell membranes. They have shown to be important components in the development of biosensing devices where the bilayer acts as a host for transmembrane proteins, such as ion channels, that are utilized as sensing elements.

5. 3. Mesoporous Building Blocks : Synthesis and Characterization of Mesoporous Silica Particles and Films

   Author : Emma M. Björk; Magnus Odén; Fredik Söderlind; José Córdoba; Mika Lindén; Linköpings universitet; []
   Keywords : ;

   Abstract : Catalyst supports, drug delivery systems, hosts for nanoparticles, and solar cells are just some examples of the wide range of exciting applications for mesoporous silica. In order to optimize the performance of a specific application, controlling the material’s morphology and pore size is crucial. READ MORE

6. 4. Enzyme Immobilization in Mesoporous Silica

   Author : Hanna Gustafsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; immobilization; lipase; Mesoporous; particle morphology; feruloyl esterase; enzyme; encapsulation; silica; pore size; trypsin;

   Abstract : Catalysts are widely used in many industries for production of chemicals, pharmaceuticals, fuels and energy. There is a need for more sustainable production processes, with reduced energy and raw material consumption together with a reduction in waste and toxic by-products. READ MORE

7. 5. Mesoporous Silica Formed with Triblock Copolymers

   Author : Katarina Flodström; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; 1H NMR; TEM; SAXS; in situ; mechanism of formation; cubic Ia3d; cubic Im3m; Mesoporous; synthesis; Pluronic; SBA-16; SBA-15; hexagonal p6mm; synchrotron SAXS; Physical chemistry; amphiphilic polymers; silica;

   Abstract : The formation of highly ordered mesoporous silica materials, using PEO-PPO-PEO amphiphilic triblock copolymers (so-called Pluronics) as structure directing agents, has been studied. The materials are formed through the addition of a silica source to a polymer solution of low concentration (2.5 wt ) under acidic conditions. READ MORE
