1. Diffusion of dynamic innovations : A case study of residential solar PV systems
Abstract : In the literature on diffusion of innovations, it is widely known that the characteristics and socio-environmental settings of adopters do evolve in space and time. What about innovations themselves? During the diffusion process, don’t some innovations continuously alter in space and time? If so, how does the dynamic character of an innovation influence the diffusion process? In previous research, it has been often assumed that innovations do not continuously alter or get modified when diffusing from a source to potential adopters. READ MORE

2. 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

3. lac of Time : Transcription Factor Kinetics in Living Cells
Abstract : Gene regulation mediated by transcription factors (TFs) is essential for all organisms. The functionality of TFs can largely be described by the fraction of time they occupy their regulatory binding sites on the chromosome. DNA-binding proteins have been shown to find their targets through facilitated diffusion in vitro. 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. Hydrogen in nano-sized metals : Diffusion and hysteresis effects
Abstract : Metal hydrides can be used as hydrogen storage materials for fuel cells and batteries, and as sensors for detecting hydrogen gas. The use of metal hydrides for hydrogen storage can be hindered by poor kinetics and low capacity. Moreover, poor sensitivity, long recovery and response time, limit the applications of metal hydrides as hydrogen sensors. READ MORE
