Chemical interactions between 2-aminobenzothiazole (ABT) and a soil humic acid (HA) extracted from a gleyic planosol were investigated by solid-state 13C CP/MAS NMR spectroscopy. Reactions of the HA with ABT 13C-labelled ...
We report on the use of a pulsed gradient spin-echo imaging sequence for the three-dimensional (3D) imaging of water transport properties in two porous media: 2mm glass-beads and 0.15mm quartz-sand mixed with 2mm glass-beads. ...
