We developed an analytical relationship between nuclear magnetic relaxation and interparticle spacings in polymer nanocomposites filled with paramagnetic-impurity-containing clay nanoparticles. Using (1)H NMR relaxometry, clay nanoparticle dispersion was quantified and agrees with interparticle spacing distributions determined from statistical analysis of TEM images. Some information on the ove...

We extend previous work on symbolic code generation for efficient solvers in the domain of image and signal processing, to take advantage of recurrence relations for efficiently generating model function values corresponding to a regularly-sampled time series. Firstand zeroth-order recurrences are symbolically identified by Maple. Two example applications to Magnetic Resonance Spectroscopy and ...

Fiore Sardo (FS), a traditional Italian cheese, is present in the market as heterogeneous variety of products. The use heat-treated (HT) milk forbidden by official production protocol, but no analytical method able to detect heat application yet available. Here, combined magnetic resonance imaging (MRI) relaxometry and image analysis approach recognize FS made from raw presented. Artisanal chee...

Quantitative MRI (qMRI) provides standardized measures of specific physical parameters that are sensitive to the underlying tissue microstructure and are a first step towards achieving maps of biologically relevant metrics through in vivo histology using MRI. Recently proposed models have described the interdependence of qMRI parameters. Combining such models with the concept of image synthesis...

The interaction between Laponite and other constituents in complex systems greatly depends on its available surface area. We report a study of exfoliation dynamics of Laponite in aqueous suspensions by NMR relaxometry. It showed that Laponite particles exfoliate to the same extent in a concentration range of 0.5-3% w/w. Faster increase of specific wetted surface area of Laponite particles in mo...
