  1. 31. A journey towards complete structure determination of zeolites by electron crystallography methods

    Författare :Elina Kapaca; Xiaodong Zou; Philippe Boullay; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron crystallography; Zeolites; Structure determination; Rotation electron diffraction; Continuous rotation electron diffraction; Disorder; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Electron crystallography has recently become very successful for structural studies of materials with sub-micrometer sized crystals. In this thesis two major techniques have been applied for structure elucidation – 3-dimensional electron diffraction (3D ED) and high-resolution transmission electron microscopy (HRTEM) imaging.

  3. 32. Luminosity determination and simulation of the LUCID detector at the ATLAS experiment

    Författare :Jacob Groth-Jensen; Partikel- och kärnfysik; ATLAS Collaboration; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; LUCID; Luminosity determination; Performance study; ATLAS; Gauge boson production; Fysicumarkivet A:2010:Groth-Jensen;

    Sammanfattning : The aim of this thesis is to describe how the luminosity can be measured in the ATLAS experiment at the Large Hadron Collider. Luminosity is a fundamental quantity that is used in most physics studies at the LHC. For example in order to measure cross sections. LÄS MER

  4. 33. Structure determination of ribosomal proteins and development of new methods in biomolecular NMR

    Författare :Magnus Helgstrand; KTH; []
    Nyckelord :nuclear magnetic resonance; structure determination; ribosomal proteins; NMR simulations; NMR theory; NMR assignment software; semiautomatic assignment;

    Sammanfattning : This thesis concerns different areas of biomolecular nuclearmagnetic resonance spectroscopy (NMR). In the first part of thethesis a new formalism for simulations of NMR pulse sequencesis introduced. The formalism is derived both from classicalmechanics and quantum mechanics and is presented forhomonuclear and heteronuclear spin systems. LÄS MER

  5. 34. Determination of actinides using ICP-SFMS

    Författare :Ulrika Nygren; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Interest in the determination of the actinides using ICP-MS has steadily increased with the development of systems capable of more sensitive and precise measurements. However, the analysis of less abundant actinides such as Pu and Am is not straightforward due to the need for chemical separation of these elements prior to determination. LÄS MER

  7. 35. Determination of protolytes by flow procedures : applications to liquors from the hydrometallurgical nickel industry

    Författare :Isel Gertrudis Cortés Nodarse; KTH; []
    Nyckelord :;

    Sammanfattning : The general intention of this work is to contribute inreplacing complicated and time consuming titration methods foracid/base determination in cases where a rapid answer is morevaluable than a very high accuracy. The versatility of FlowInjection Analysis (FIA) is utilised for the determination ofprotolyte compounds, considering their role in our daily lifeas well as in science and technology. LÄS MER
