  2. 1. Residual and critical saturation in geological storage of CO2 : results from field studies, pore-network modelling and laboratory experiments

    Author : Ramin Moghadasi; Auli Niemi; Philip Ringrose; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geological CO2 storage; Residual trapping; Gas remobilization; Field experiment; Numerical modelling; Pore-network modelling; Pore-scale imaging;

    Abstract : Geological storage of CO2 in deep saline aquifers is a promising technology in the combat to reduce the atmospheric emissions of CO2. A critical component in this solution is the estimation of aquifer’s in situ capability to store CO2. READ MORE

  4. 2. Foam modeling including pore gas interaction for crashworthiness analysis

    Abstract : Foams are used in vehicles for three main functions: enhancing comfort, e.g.soft foams used in seats cushions, energy absorbtion, e.g. READ MORE

  5. 3. Physico-Chemical Properties of Plant Polysaccharides Investigated with NMR Techniques

    Author : Åsa Östlund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR diffusometry; Dissolution of cellulose; Chemical shift imaging; Fiber hornification; Xylan; Molecular weight; Pore size distribution; Cryoporometry; Cellulose solution; 19F NMR; Gelation of cellulose; Self-diffusion; Pulsed field gradient NMR; TBAF DMSO; 1H NMR;

    Abstract : In the lead of developing new biomaterials from plant sources it is of importance to be able to control and vary the properties, such as flexibility, strength, and hygroscopicity of the final material. These properties are highly directed by the interactions between constituents on a molecular level. READ MORE

  6. 4. Mesostructured particulate silica materials with tunable pore size : Synthesis, characterization and applications

    Author : Malin Helena Sörensen; Per Claesson; Viveka Alfredsson; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesoporous materials; aersol-based process; emulsion-based process; biocatalysis; sustained release; 3D hexagonal; 2D hexagonal; powder; spherical particles; liquid crystalline phases; AFM-porosimetry; Pluronic; Chemistry; Kemi;

    Abstract : Colloidal assemblies of surfactants and polymers in aqueous solutions have been used by human mankind for hundreds of years and they are of great importance in many of our technological processes, such as fabrication of soap and papermaking. Less than two decades ago the idea of using colloidal assemblies as templates of inorganic materials was borne. READ MORE

  7. 5. Sintering behaviour of α and β solid solution sialons

    Author : Stig-Björn Westberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Some ceramics have the ability to form solid solutions. One such group are the sialons, which contain silicon, aluminium, oxygen and nitrogen in specific proportions. Through a stabilizing process with yttrium, not only beta-sialons but also alfa-sialons can be produced. READ MORE
