  1. 1. Swelling and Microstructure of Nanoplatelet Systems

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Theoretical Chemistry

    Author : Axel Thuresson; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoplatelets; Model clay system; Coarse grained models; Statistical mechanics; MC simulations; MD simulations; SAXS; Cryo-TEM; Laponite; Montmorillonite; Swelling; Tactoid;

    Abstract : Many clay minerals consist of charged nanoplatelets that swell in an aqueous solution. The swelling and the microstructure depend on the type of clay mineral but are also dependent on, for example, the ionic composition and the temperature of the solution. READ MORE

  2. 2. Intracranial Pressure in Traumatic Brain Injury

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Theoretical Chemistry

    Author : Sima Shahsavari; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brain Swelling; Cerebral Autoregulation; Secondary Brain Injury; Traumatic Brain Injury; Cerebral Compliance; Intracranial Dynamics; Intracranial Pressure;

    Abstract : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainely focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity (ICP) has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. READ MORE

  3. 3. Swelling of Cellulose Fibrillar Matrices and Gels

    University dissertation from KTH Royal Institute of Technology

    Author : Pernilla Karlsson; Lars Wågberg; Per Tomas Larsson; Eero Kontturi; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swelling; hydrogel; cellulose; wood; cellulose fibrils; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : One of the major challenges of today´s society is to find a sustainable way to create a living based on the resources on earth. It is a challenge that includes a transition from fossil-based materials to renewable/biodegradable raw materials and also the creation of an environmentally friendly circular material flow.

  4. 4. Polymer Gels: Modeling the Swelling Behavior

    University dissertation from Physical Chemistry 1, Lund University

    Author : Stefanie Schneider; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Polymerteknik; biopolymers; Polymer technology; binding isotherms; polyelectrolyte-surfactant interactions; discontinuous volume transition; gel swelling; Monte Carlo simulation; polyelectrolyte gels;

    Abstract : This thesis is concerned with the swelling behavior of polyelectrolyte gels. The thesis can be divided into two parts. Part one deals with the modeling and computer simulation of the gel swelling. READ MORE

  5. 5. Evaluation of the Tactoid Formation in Clay Systems

    University dissertation from mediatryck, Lund University

    Author : Maria Jansson; [2019-04-12]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Nano-plattor; Taktoider; Anisotropi; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; Clay; Montmorillonite; Nanoplatelets; Tactoid; Anisotropy; Coarse-grained models; MD simulations; MC simulations; SAXS; Swelling pressure;

    Abstract : Clay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. READ MORE
