  2. 21. Transmission Electron Microscopy for Characterization of Structures, Interfaces and Magnetic Moments in Magnetic Thin Films and Multilayers

    Author : Hans Lidbaum; Klaus Leifer; Peter Svedlindh; Josef Zweck; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy; TEM; magnetism; multilayer; superlattice; thin films; amorphous metals; electron energy-loss magnetic circular dichroism; EMCD; electron diffraction; Magnetism; Magnetism; Surfaces and interfaces; Ytor och mellanytor; Physics; Fysik; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik; Materiefysik; Physics of Matter;

    Abstract : Structural characterization is essential for the understanding of the magnetic properties of thin films and multilayers. In this thesis, both crystalline and amorphous thin films and multilayers were analyzed utilizing transmission electron microscopy (TEM). READ MORE

  4. 22. Automating STED microscopy for functional and structural live-cell imaging

    Author : Jonatan Alvelid; Ilaria Testa; Eggeling Christian; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; STED; microscopy; nanoscopy; super-resolution microscopy; automation; image analysis; fluorophores; Biologisk fysik; Biological Physics;

    Abstract : Optical microscopy imaging methods are today invaluable tools for studies in life sciences as they allow visualization of biological systems, tissues, cells, and sub-cellular compartments from millimetres down to nanometres. The invention and development of nanoscopy in the past 20 years has pushed fluorescence microscopy down to the nanoscale, reaching beyond the natural diffraction limit of light that does not allow focusing of visible light below sizes of around 200 nm, and into the realm of what was previously only thought possible with electron microscopy.

  5. 23. Multimodal and multiscale characterization of bone and bone interfaces in health and disease

    Author : Chiara Micheletti; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone; osseointegration; characterization; mineralization; ultrastructure; diabetes; osteoporosis; MRONJ; surface functionalization; local drug delivery; titanium; bioactive glass; imaging; spectroscopy; microscale; nanoscale; micro-computed X-ray tomography; micro-Raman spectroscopy; scanning electron microscopy; transmission electron microscopy; PFIB-SEM tomography; electron tomography;

    Abstract : Seeing is believing. Our understanding of phenomena often involves their direct observation. However, bone architecture is challenging to visualize given its multi-level hierarchical organization. READ MORE

  6. 24. Light’EM up! : structural characterization of light-driven membrane protein complexes by cryogenic electron microscopy

    Author : André Tomás Graça; Wolfgang P. Schröder; Johannes Messinger; Karina Persson; Werner Kühlbrandt; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D reconstruction; Arabidopsis thaliana; assembly; chlorophyll; cryo-EM; cyanobacteria; Deinococus radiodurans; electron; land plants; membrane protein complexes; Photosystem II; proton; single-particle analysis; S-Layer Deinoxanthin Binding Complex SDBC ; water.; Biochemistry; biokemi; biologisk kemi; biological chemistry;

    Abstract : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. READ MORE

  7. 25. The laryngeal mucosa and the superior laryngeal nerve of the rat : an immunohistochemical and electron microscopic study

    Author : Siw Domeij; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superior laryngeal nerve; paraganglia; substance P; calcitonin gene-related peptide; neuropeptide Y; vasoactive intestinal polypeptide; enkephalin; mast cells; electron microscopy; immunohistochemistry;

    Abstract : Neuropeptides are present in nerve fibers of the upper and lower airways. Local release of these substances may be of importance for the pathophysiology of airway disorders and may play a role in responses to different stimuli. However, little is known about the distribution of neuropeptides in the larynx. READ MORE
