  1. 16. Structural study of zeolites utilizing novel electron crystallographic methods A voyage into the world of zeolite structures

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Tom Willhammar; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron crystallography; zeolites; structure determination; disorder; electron microscopy; strukturkemi; Structural Chemistry;

    Abstract : Electron crystallography has evolved as a powerful method for structural characterization of a wide range of materials. It has two significant advantages over other methods for structure determination, e.g. X-ray diffraction. READ MORE

  2. 17. Design and characterization of nanoparticles and their assemblies Transmission electron microscopy investigations from atomic to mesoscopic length scales

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Arnaud Mayence; Lennart Bergström; Liberato Manna; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; electron microscopy; materialkemi; Materials Chemistry;

    Abstract : Transmission electron microscopy (TEM) is a powerful and versatile tool for investigating nanomaterials. In this thesis, various transmission electron microscopy techniques are used to study the chemical and structural features of different types of inorganic nanoparticles of well-defined morphologies as well as their assemblies.

  3. 18. Protein structure dynamics and interplay by single-particle electron microscopy

    University dissertation from Stockholm : KTH

    Author : Hans Elmlund; KTH.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biophysics; biochemistry; molecular; NATURAL SCIENCES Chemistry Physical chemistry Biophysical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Biofysikalisk kemi;

    Abstract : Single-particle cryo-electron microscopy (cryo-EM) is a method capable of obtaining information about the structural organization and dynamics of large macromolecular assemblies. In the late nineties, the method was suggested to have the potential of generating “atomic resolution” reconstructions of particles above a certain mass. READ MORE

  4. 19. Middle ear structure in relation to function the rat in middle ear research

    University dissertation from Umeå : Umeå universitet

    Author : Nils Albiin; Umeå universitet.; [1985]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; Eustachian tube; ear; middle; tympanic membrane; palatal muscles; mucous membrane; blood vessels; mast cells; otitis media; microscopy; electron;

    Abstract : The present study was undertaken to evaluate the rat as a model for middle ear re­search. The rat was chosen primarily because the gross structure of its middle ear shows several similarities to that of man. READ MORE
