  1. 6. Protein-water interactions studied by molecular dynamics simulations

    Författare :Filip Persson; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MD simulations; NMR nuclear magnetic resonance ; MRD; water dynamics; protein dynamics; protein hydration; Amide hydrogen exchange; Internal water; compressibility;

    Sammanfattning : Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. LÄS MER

  3. 7. Macroscopic Volume and Free Volume of Polymer Blends and Pressure-densified Polymers

    Författare :Marcus Schmidt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; free-volume theories; refractive index; Lorentz-Lorenz equation; loss tangent; Avrami equation; freezing fractions; copolymers; polymer blends; pressure dilatometry; Tait equation of state; free-volume distributions; pressure-densified polymers; entropy of melting; dynamic-mechanical analysis; positronium; positron annihilation; free volume; cavity size; polymers; bulk modulus; PVT; phase separation; compressibility; thermal expansivity;

    Sammanfattning : The macroscopic volume V as a function of pressure P and temperature T is obtained from PVT measurements. PVT data is sensitive to the state of polymers and changes therein. Moreover, PVT data gives access to the free-volume fraction. LÄS MER

  4. 8. On Suction Box Dewatering Mechanisms

    Författare :Peter Åslund; Bo Norman; Timoty Patterson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Suction box; vacuum; water removal; compressibility; displacement; rewetting; laboratory equipment; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : In previous studies on suction box dewatering, three mechanisms were identified that determine the dry content of a web, viz. web compression, displacement of water by air and rewetting. LÄS MER

  5. 9. Compressibility and density of lubricants in transient loading

  7. 10. Molecular Dynamic Simulations of Biological Membranes

    Författare :Qaiser Waheed; Olof Edholm; Friederike Schmid; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phospholipids; area compressibility; undulations; quantum corrections; cholesterol; phase transition; segregation;

    Sammanfattning : Biological membranes mainly constituent lipid molecules along with some proteins and steroles. The properties of the pure lipid bilayers as well as in the presence of other constituents (in case of two or three component systems) are very important to be studied carefully to model these systems and compare them with the realistic systems.
