Graphene is a two dimensional material, a single layer of carbon atoms arranged in a hexagonal lattice, known for its exceptional strength, flexibility, and electrical conductivity. It's incredibly thin, a million times thinner than a human hair, and yet stronger than steel. These unique properties make it a promising material for a wide range of applications, from electronics and energy storage to composites and biomedicine. Source: Google Search
NODDI, which stands for Neurite Orientation Dispersion and Density Imaging, is a technique used in diffusion MRI to assess the microstructure of brain tissue. It provides more specific markers of brain tissue microstructure than standard diffusion tensor imaging (DTI). NODDI models the diffusion signal as the contribution of three compartments: intracellular, extracellular, and cerebrospinal fluid. This allows researchers to estimate parameters like neurite density and orientation dispersion, offering insights into the complexity of neurites (axons and dendrites) in the brain.
