2. 1. Structured Nanoporous Materials for Biogas Upgrading

   Author : Kritika Narang Landström; Farid Akhtar; Andreas Kaiser; George Shimizu; Marta-Lena Antti; Manuel Moliner Marín; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoporous materials; biogas upgrading; zeolites; metal-organic framework; carbon capture; separation kinetics; Materialteknik; Engineering Materials;

   Abstract : Porous materials have shown potential for solving one of the significant challenges to sequestering CO2 gas from point sources. Microporous materials, zeolites and metal-organic frameworks (MOFs) are porous materials with tailorable adsorptive properties to develop higher performance for an energy-efficient CO2 separation.

4. 2. Protective and Nanoporous Alumina Films Studied in situ by X-ray and Electrochemical Methods

   Author : Jonas Evertsson; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; XRR; XPS; XRF; GTSAXS; EIS; Synchrotron Radiation; Native oxide; Anodization; Anodic aluminum oxide; Nanoporous aluminum oxide; Single crystal; Aluminum alloys; in situ; Fysicumarkivet A:2018:Evertsson;

   Abstract : In this thesis, the studies of native and anodic oxides on both aluminum model single crystal surfaces as well as on aluminum alloys found in applications are presented. The focus has been on the characterization in situ as the oxide is growing by an electrochemical process called anodization. READ MORE

5. 3. Nanocomposites made from nanoporous cellulose fibre

   Author : Anna Svensson; Lars Wågberg; Eva Malmström Jonsson; Gunnar Westman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis explores how to use the dry nanoporous structure of cellulosic fibres in new types of composite materials. A large effort was also given on how to correctly characterize the structure of fibres where the wet structure has been preserved also in the dry state. READ MORE

6. 4. Bioactive Surgical Implant Coatings with Optional Antibacterial Function

   Author : Mirjam Lilja; Maria Strømme; Håkan Engqvist; Håvard Haugen; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydroxyapatite; titanium dioxide; photocatalysis; antibacterial effect; antibiotic release; biomimetic coating; co-precipitation; tobramycin;

   Abstract : Device associated infections are a growing problem in the field of orthopaedics and dentistry. Bacteria adhering to implant surfaces and subsequent biofilm formation are challenging to treat with systemic administered antibiotics. READ MORE

7. 5. Templating and self-assembly of biomimetic materials

   Author : Christian Mille; Lennart Bergström; Mika Linden; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomimetic; biotemplating; self-assembly; triply periodic minimal surfaces; the gyroid; photonic crystals; band gap; structural color; chirality; butterflies; membrane proteins; lipid bilayers; sol-gel; mesostructured; polyhedral nanofoams; Materials Chemistry; materialkemi;

   Abstract : This thesis focuses on the use of biomolecular assemblies for creating materials with novel properties. Several aspects of biomimetic materials have been investigated, from fundamental studies on membrane shaping molecules to the integration of biomolecules with inorganic materials. READ MORE
