  2. 1. Characterization of Micro-Structures in Materials

    Author : Henrike Häbel; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Clustering; colloidal nanoparticle gels; image analysis; mass transport; point pattern; polymer blended films; pore shape; polymer blended films;

    Abstract : On developing the next generation sustainable soft materials, it is often crucial to understand and control their properties and function. Whereas a characterization of three-dimensional data is desirable in corresponding studies, often two-dimensional data are less time consuming to obtain. READ MORE

  4. 2. Exploring expandable microspheres as a novel pore former in gel-cast macroporous alumina

    Author : Linnéa Andersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gel casting; macroporosity; Al2O3; near-net shape; expandable microspheres; layer-by-layer adsorption; polyelectrolyte; multilayer; colloids; X-ray micro-computed tomography; Lab CT; Organic chemistry; Organisk kemi;

    Abstract : Expandable microspheres have been explored as sacrificial templates for the production of macroporous ceramics. Concentrated alumina powder suspensions that contain expandable microspheres have been consolidated by gel-casting. READ MORE

  5. 3. Nanocellulose based 3D printed hydrogel scaffolds for cartilage and bone regeneration : Tuning of composition, pore structure and functions

    Author : Sahar Sultan; Aji P. Mathew; Lennart Bergström; Gustav Nyström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose materials; 3D printing; gradient biphasic hydrogel scaffolds; metal-organic frameworks; hydroxyapatite; cartilage and bone regeneration; osteochondral scaffolds; materialkemi; Materials Chemistry;

    Abstract : Biobased-materials with customized scaffolds have played a prominent role in the success of tissue engineering (TE). Cellulose nanomaterials (CNM) isolated from the abundant biopolymer, cellulose, is explored in this thesis for TE engineering due to its versatile properties such as biocompatibility, high specific strength, surface functionality and water retention capacity.

  6. 4. Membrane emulsification: modelling interfacial and geometric effects on droplet size

    Author : Marilyn Rayner; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pore geometry; membrane emulsification; Gases; Surface Evolver; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; modelling; Livsmedelsteknik;

    Abstract : Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. READ MORE

  7. 5. Molecular and ultrastructural analysis of Tpr, a nuclear pore complex-attached coiled-coil protein

    Author : Manuela Hase; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Anchored in the nuclear envelope, nuclear pore complexes (NPCs) are large multiprotein complexes which serve as the gateway for nucleocytoplasmic transport. In vertebrates, a 267kDa protein termed Tpr has been localized to the nucleoplasmic side of the NPCs. The function of Tpr has remained largely elusive. READ MORE
