2. 1. Structural transitions of proton-gated ion channels : Involving pH sensing, heterogeneity and lipid interactions

   Author : Urška Rovšnik; Erik Lindahl; Hugues Nury; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ion channels; cryo-electron microscopy; pH gating; simulations; structure-function relationship; GLIC; DeCLIC; biokemi; Biochemistry;

   Abstract : Studying protein structure and function involves analyzing the relationship between a protein's three-dimensional assembly and its dynamic biochemical activity. The superfamily of pentameric ligand-gated ion channels (pLGICs) constitutes a classic yet illuminating experimental system for structure-function studies. READ MORE

4. 2. Structural Studies of Large dsDNA Viruses using Single Particle Methods

   Author : Hemanth Kumar Narayana Reddy; Martin Svenda; Sarah Butcher; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

   Abstract : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. READ MORE

5. 3. Stainless steels fabricated by laser melting : Scaled-down structural hierarchies and microstructural heterogeneities

   Author : Kamran Saeidi; Zhijian Shen; Xiaoxu Huang; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Selective laser melting; Stainless steel; Structural hierarchies; Microstructure heterogeneity; Mechanical properties; Materials Chemistry; materialkemi;

   Abstract : Additive manufacturing is revolutionizing the way of production and use of materials. The clear tendency for shifting from mass production to individual production of net-shape components has encouraged using selective laser melting (SLM) or electron beam melting (EBM). READ MORE

6. 4. Structure Dynamics and Heterogeneity in Soft Materials Determined by FRAP

   Author : Joel H Hagman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft materials; Fluorescence recovery after photobelaching; Confocal microscopy; Heterogeneity; Structure dynamics;

   Abstract : A common interest in industry today is to be able to control the mass transport inside soft (bio) materials in order to tailor both release and uptake of substances. Most of the materials used are heterogeneous, quite often multiphase or compound materials and often undergo dynamic changes; it is therefore important to have control over the local microstructure in order to tailor the macroscale properties.
