  1. 1. Structure Determination and Prediction of Zeolites : A Combined Study by Electron Diffraction, Powder X-Ray Diffraction and Database Mining

    Author : Peng Guo; Xiaodong Zou; Christine Kirschhock; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; zeolites; rotation electron diffraction; structure determination; structure prediction; strong reflections approach; Inorganic Chemistry; oorganisk kemi;

    Abstract : Zeolites are crystalline microporous aluminosilicates with well-defined cavities or channels of molecular dimensions. They are widely used for applications such as gas adsorption, gas storage, ion exchange and catalysis. The size of the pore opening allows zeolites to be categorized into small, medium, large and extra-large pore zeolites. READ MORE

  2. 2. Infarct size and myocardial function : A methodological study

    Author : Lene Rosendahl; Jan Engvall; Thor Edvardsen; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The size of a myocardial infarction (MI) and the concurrent effect on left ventricular (LV) function are essential for decisions regarding patient care and treatment. Images produced with the late gadolinium enhancement (LGE) technique visualize the scar with high spatial resolution. READ MORE

  3. 3. Optical characterisation of subwavelength dielectric particles using particle tracking beyond the Stokes-Einstein relation

    Author : Erik Olsén; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; off-axis holography; Optical microscopy; size determination; particle tracking; partial slip; lipid vesicles; particle dynamics;

    Abstract : As the importance of nanoparticles continues to increase in both biology and industrial processes, so does the need for accurate and versatile characterisation methods. However, most light-based methods to quantify size and refractive index of individual particles are either limited to snapshot observations, particles larger than the wavelength of light, non-dynamic particle properties, or assuming the hydrodynamic boundary conditions without experimental evaluation.

  4. 4. Supported Lipid Membranes and Their Use for the Characterization of Biological Nanoparticles

    Author : Silver Jõemetsa; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; microfluidics; size determination; fluorescence microscopy; lipophilic dyes; supported lipid bilayer; diffusion;

    Abstract : Biological nanoparticles (BNPs) are nano-sized lipid vesicles of biological origin, which are involved in multiple biological processes. BNP characterization techniques are critical for improving the understanding of how these particles contribute to cellular communication, viral infections and drug-delivery applications. READ MORE

  5. 5. Hydrodynamic flow for deterministic sorting of cell-membrane components

    Author : Björn Johansson Fast; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; Diffusion; Microfluidics; Native membrane vesicles; Single particle tracking; Protein enrichment; Hydrodynamic forces; Supported lipid bilayer; Size determination;

    Abstract : The biological membrane, an amphiphilic structure that is the barrier between the cell interior and exterior, is one of the vital building blocks of all cells. Not only does it define the outer boundaries of the cell, it also carries important biological function by virtue of the proteins and other molecules that constitute the membrane, the function of which is in turn intimately coupled to their association with the lipid-based membrane.
