  2. 1. Assemblies of Colloidal Hydrochar Nanoparticles and their Derived Activated Carbons for CO2 Sorption

    Author : Xia Wang; Niklas Hedin; Gunnar Svensson; Oren Regev; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colloids; hydrothermal carbonization; glucose; directed assembly; reactive infiltration; templating; silicon carbide; tricopper silicide; redispersion; nanoparticles; chemical activation; activated carbons; CO2 sorption; Materials Chemistry; materialkemi;

    Abstract : Carbon-rich colloids are of great fundamental and technological interest and in this thesis, I tested a range of hypotheses and studied aspects of small hydrochar-based colloids and their colloidal and material chemistry. Crude hydrochar dispersions were synthesized by hydrothermal carbonization of glucose and purified by dialysis. READ MORE

  4. 2. Multifunctional Carbon Foams by Emulsion Templating : Synthesis, Microstructure, and 3D Li-ion Microbatteries

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Battery; Carbon; Electrochemical; Electrodeposition; Emulsion; Energy; Exfoliation; Foam; Lithium; Microbattery; Multifunctional; Nanoparticles; Polyaniline; Polymer; Power; Sol-gel; Storage; Structured; Three-dimensional; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. READ MORE

  5. 3. 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

  6. 4. Molecular sieve macrostructures prepared by resin templating

    Author : Lubomira Tosheva; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : A novel template-based method for the preparation of molecular sieve macrostructures was developed. Silicalite-1, ZSM-5 and zeolite beta spheres were prepared by the method. The procedure was also used to produce amorphous silica macrostructures. Anion exchange resin beads were employed as macrotemplates to host the guest silica materials. READ MORE

  7. 5. Shaping Macroporous Ceramics : templated synthesis, X-ray tomography and permeability

    Author : Linnéa Andersson; Lennart Bergström; Ludwig Gauckler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alumina; ceramic; CO2 capture; colloidal processing; expandable microspheres; gel casting; layer-by-layer; macroporosity; near-net shape; non-destructive evaluation; permeability; porosity; sacrificial templating; X-ray computed tomography; Chemistry; Kemi; Materials Chemistry; materialkemi;

    Abstract : Macroporous ceramic materials have found widespread technological application ranging from particulate filters in diesel engines, tissue engineering scaffolds, and as support materials in carbon capture processes. This thesis demonstrates how the pore space of macroporous alumina can be manipulated, analysed in three-dimensions (3D) using visualisation techniques, and functionalised with a CO2-adsorbing material.
