  2. 1. Ions in models of articular cartilage : The importance of electrostatic interactions for transport and equilibrium distribution

    Author : Jenny Algotsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; articular cartilage; Donnan equilibrium; diffusion; MRI; Monte Carlo simulations; dGEMRIC;

    Abstract : Osteoarthritis (OA) is a degenerative disease that affects articular cartilage, which covers the surfaces of the bones in synovial joints. At later stages the disease can result in major loss of articular cartilage and thus lead to major disability. READ MORE

  5. 3. Cation adsorption properties of substituted kraft fibres : an experimental and thermodynamic modelling study

    Author : Ola Sundman; Lars-Olof Öhman; Per Persson; Janne Laine; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kraft fibres; Donnan equilibria; ion exchange; acid base properties; potentiometric titrations; thermodynamic modelling; NPEs; GaAl12 7 ; EXAFS; Chemistry; Kemi;

    Abstract : Acid/base and metal ion adsorption properties have been investigated for a range of chemically modified bleached Kraft fibre materials (pulps). The studies were performed via potentiometric titrations, Flame Atomic Absorbtion (and Emission) Spectroscopy, Inductively Coupled Plasma Optical Emission Spectroscopy and Extended X-ray Absorbtion Fine Structure measurements.

  6. 4. Capacitive Mixing for Extracting Concentration Gradient Energy

    Author : Zhi Zou; Longcheng Liu; Chia-Hung Hou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive mixing; salinity gradient energy; salt difference energy; electric double layer; flow electrode CapMix; kapacitiv blandning; salthaltsgradientenergi; saltskillnadsenergi; elektriskt dubbelskikt; flödeselektrod CapMix.; Chemical Engineering; Kemiteknik;

    Abstract : Capacitive mixing (CapMix) is a renewable method of extracting energy from the salinity gradient energy (SGE) between seawater and freshwater. The classical CapMix systems using solid electrodes generate electricity by periodically circulating seawater and freshwater into the CapMix system. READ MORE

  7. 5. Some aspects of adsorption in displacement washing of pulp

    Author : Karin Mattsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : AbstractThere are many aspects on how to improve the paper pulping process. In the washing sequence improvements to decrease the discharge to the environment can be achieved by closure of the liquid system and recycling liquid from other parts pulp process. READ MORE
