The mechanism of Au (I) extraction has been characterized using 198Au radiometry, thermodynamic equilibrium, Karl-Fischer titration and FT-IR spectroscopy techniques. The results indicate that the extraction follows ionic combination and solvent interaction mechanism. The stoichiometry of the extracted species is 1:1:4:4 for TDMBA+: Au(CN)2- : TBP : H2O. The microstructure model of the extracted complex is a supramolecular structure via hydrogen bonding, ion dipole interaction and ionic combination. The extraction process can be described as micelles in the aqueous phase transfer into the organic phase and reversed micelles or microemulsion (W/O) form in the organic phase.

The single-layer black phosphorus is characterized by its puckered configuration that pos- sesses the hinge-like behavior, which leads to the highly anisotropic in-plane Poisson＇s ratios and the negative out-of-plane Poisson＇s ratio. We demonstrate that the hinge-like mechanism can be described by the angle-angle cross interaction, which, combined with the bond stretching and angle bending interactions, is able to provide a good description for the mechanical properties of single-layer black phosphorus. We also propose a nonlinear angle-angle cross interaction, which follows the form of Stillinger-Weber potential and can be advantageous for molecular dynamics simulations of single-layer black phosphorus under large deformation.
