  2. 1. Protein stability and mobility in live cells : Revelation of the intracellular diffusive interaction organization mechanisms

    Author : Xin Mu; Mikael Oliveberg; Johan Elf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusive interactions; macromolecular crowding; protein thermodynamic stability; protein mobility; in-cell NMR; Hofmeister series; Biochemistry; biokemi;

    Abstract : Biochemical processes inside living cells take place in a confined and highly crowded environment. As such, macromolecular crowding, one of the most important physicochemical properties of cytoplasm, is an essential element of cell physiology. READ MORE

  4. 2. Diffusive interactions play an important role in protein stability and mobility : Investigations of the intracellular milieu using in-cell NMR

    Author : Therese Sörensen; Mikael Oliveberg; Per Jemth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in-cell NMR; protein-protein interactions; mobility; stability; thermodynamics; Nuclear Magnetic Resonance; stopped-flow spectroscopy; proteins; SOD1; HAH1; TTHA1718; cells; cytoplasm; humans; bacteria; ions; polyions; electrostatics; biokemi; Biochemistry;

    Abstract : Proteins are crucial for all cellular life. Every signal received by a cell, and every response to it, is mediated by proteins. Inside cells, these proteins diffusively sample each other’s surfaces, as they travel through the cytoplasm in search of their specific interaction partners. READ MORE

  5. 3. How transient interactions in the crowded cytosol affect protein mobility and stability

    Author : Sarah Leeb; Mikael Oliveberg; Magnus Wolf-Watz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusive transient interactions; macromolecular crowding; protein stability; in-cell NMR; protein evolution; Biophysics; biofysik;

    Abstract : Most biochemical reactions have evolved in crowded intracellular environments. However, the complexity of intracellular environments is often neglected in structural or functional studies of proteins. READ MORE

  6. 4. Interactions of cellulose and model surfaces

    Author : Johanna Stiernstedt; Mark Rutland; William Ducker; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : The focus of this thesis is fundamental surface force and friction studies of silica and cellulose surfaces, performed mainly with the atomic force microscope (AFM). The normal interactions between model cellulose surfaces have been found to consist of a longer range double layer force with a short range steric interaction, the nature of which is extensively discussed.

  7. 5. Diffusive Mass Transport of Ions in Wood

    Author : Reddysuresh Kolavali; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; wood; mass transport; impregnation;

    Abstract : Understanding the conditions that control the mass transfer of various chemicals/ions in wood is of great importance when it is subjected to various processes. Homogeneous impregnation with chemicals/ions, for example, increases the uniformity of the treatments to which the wood is subjected, reduces reaction times and may increase the yield of the final products.
