1. Structure Dynamics and Heterogeneity in Soft Materials Determined by FRAP
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.

2. Developing novel diffusion MRI methods for comprehensive analysis of restricted and anisotropic self-diffusion system
Abstract : Diffusion MRI is a non-invasive imaging technique used to study the microstructural properties of biological tissues by observing the self-diffusion of water molecules. Traditional diffusion MRI methods, based on the pulsed gradient spin-echo sequence, employ magnetic field gradients to encode information about translational motion. READ MORE

3. Pushing diffusion MRI towards new dimensions
Abstract : Diffusion-MRI techniques allow the non-invasive investigation of microstructural changes in living tissues. However, a detailed interpretation of the data is complicated by the fact that multiple microscopic environments with varying diffusion properties all contribute to the measured signal. READ MORE

4. Mechanical properties and microstructure of laser sintered and starch consolidated iron-based powders
Abstract : In powder metallurgy research field, Direct Metal Laser Sintering (DMLS) and Metal Powder Starch Consolidation (MPSC) are relatively new rapid forming techniques to fabricate complex and near net-shaped components. The working principles of DMLS are to melt and fuse metal powder layer by layer in computer controlled systems to pile up components like three dimensional printing. READ MORE

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