This laboratory/engineering study examined electric-field-induced structuring in clay-oil suspensions using WAXS, SEM, rheometry, and electrical measurements. Particle orientation was quantified via an orientational order parameter derived from diffraction peak azimuthal changes, and chain versus column formation was…

This study reports solid-state NMR (13C and 15N MAS) measurements on CuCN·N2H4 to extract copper quadrupole coupling constants and characterize cyanide ordering. Ab initio calculations were used to determine electric field gradient and chemical shielding tensor orientations needed for spectral analysis. The authors…
