1. Applications of diffusion MRI: Tensor-valued encoding, time-dependent diffusion, and histological validation
Abstract : Diffusion MRI (dMRI) sensitizes the MR signal to the diffusion of water molecules at the microscopic level and thereby non-invasively probes tissue microstructure. This is relevant when determining biological properties of tissues, for example, cancer type and its malignancy. READ MORE

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. NMR Self-Diffusion Studies and Stability Studies of Emulsions
Abstract : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. READ MORE

4. Investigation of Water Mobility using Diffusion-Sensitive MRI: The Role of q-Space Imaging, High b-Values and Diffusion Time
Abstract : Nuclear magnetic resonance (NMR) diffusometry provides important information about molecular motion on a microscopic scale. The advantage of NMR diffusometry is its ability to characterise microstructures non-invasively. This has made the method important not only in chemistry, biochemistry and materials science, but also in medicine. READ MORE

5. Reaction and Diffusion Phenomena in Biomimetic Nanoscale Reactors and Networks
Abstract : Methods for construction of geometrically complex, fully connected surface-immobilized microscopic networks of phospholipid bilayer vesicles (1-50 µm in diameter) interconnected by lipid nanotubes (100-300 nm in diameter), have been developed. The networks have controlled connectivity and are well-defined with regard to the container size, content, angle between nanotube extensions, and nanotube length. READ MORE
