  2. 41. Atomic Layer Deposition and Immobilised Molecular Catalysts Studied by In and Ex Situ Electron Spectroscopy

    Author : Payam Shayesteh; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ambient pressure XPS; Catalysis; Heterogenisation; Atomic layer deposition; HfO2; Gas phase; TDMAHf; TDMAT; Fysicumarkivet A:2019:Shayesteh;

    Abstract : The research work that I describe in my thesis deals with three different heterogenisation approaches for synthesising a heterogeneous transition metal catalyst used for direct C-H activation reactions. The three heterogenisation approaches considered in my research are: (1) heterogenisation of a molecular catalyst on a polymer support using covalent bonds, (2) heterogenisation of a catalyst on a reduced graphene oxide (rGO) support using non-covalent interactions and (3) immobilisation of a catalyst on an inorganic surface using covalent bonds and encapsulation in an inorganic matrix.

  4. 42. New Tools for Trapping and Separation in Gas Chromatography and Dielectrophoresis : Improved Performance by Aid of Computer Simulation

    Author : Fredrik Aldaeus; Anders Colmsjö; Marja-Liisa Riekkola; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas chromatography; dielectrophoresis; computer simulation; finite element method; trapping; separation; lab-on-a-chip; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Computer simulations can be useful aids for both developing new analytical methods and enhancing the performance of existing techniques. This thesis is based on studies in which computer simulations were key elements in the development of several new tools for use in gas chromatography and dielectrophoresis. READ MORE

  5. 43. Evaluating the utilisation of industrial excess heat from an energy systems perspective

    Author : Igor Cruz; Magnus Wallén; Mats Söderström; Maria Johansson; Danica Djuric Ilic; Johanna Mossberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial excess heat; Waste heat; Heat recovery; Greenhouse gas emissions;

    Abstract : Sweden aims to achieve climate neutrality by 2045. The need to immediately reduce greenhouse gas emissions in order to achieve climate targets affects industry directly. The pulp and paper sector is responsible for more than 50% of industrial energy use in Sweden. READ MORE

  6. 44. Concrete Structures Subjected to Blast Loading

    Author : Jonas Ekström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic response; numerical modelling; spalling; blast load; stain-softening; wave propagation; concrete; transverse reverse loading; cyclic crack propagation;

    Abstract : The interest for building safety with regards to highly dynamic events such as close by explosion has accelerated after the recent decades of terrorist attacks. The interest has expanded from civil defence shelters and pure military targets to also include civil buildings used for different civil functions. READ MORE

  7. 45. Multidimensional MRI of Cardiac Motion : Acquisition, Reconstruction and Visualization

    Author : Andreas Sigfridsson; Hans Knutsson; Stefan Skare; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRI; cardiac; motion; reconstruction; Image analysis; Bildanalys;

    Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all benefit from improved methods of measuring the dynamics of the heart. READ MORE
