DOI: 10.1002/nbm.4827
Abstract: Monitoring time dependence with diffusion MRI yields observables sensitive to compartment sizes (restricted diffusion) and membrane permeability (water exchange). However, restricted diffusion and exchange have opposite effects on the diffusionâweighted signal, which can lead to… read more here.

DOI: 10.1016/j.colsurfa.2017.12.012
Abstract: Abstract Poly(vinylpyrrolidone) (PVPON) and poly(acrylic acid) (PAA) were layer-by-layer (LbL) assembled to prepare thin film based on hydrogen bonding. A series of simple experiments were designed to investigate polymer chain diffusion and exchange behaviors of… read more here.
