When the plastic limit of a soil is greater than the liquid limit, then the plasticity index is reported as

Answer 1

These iron nanoparticles are intrinsically unstable and prone to aggregation; however, we rendered them stable in the long term by addition of 40 mM citrate buffer pH 3.0. In contrast, amorphous iron oxide nanoparticles (diameters of 10–40 nm) produced using R. acetosa extracts are highly stable.
