DOI: 10.1007/s11224-018-1187-0
Abstract: Contradictory literature on the alkali-assisted exfoliation of the melon and searching for the best precursors for different heptazine derivative synthesis led us to the synthesis of two cyameluric acid salts, (NH4)2[C6N7O3H] (ECN3) and (NH4)2(H9O4)[C6N7O3] (ECN5).… read more here.

DOI: 10.1103/physreve.104.045002
Abstract: Hysteretic elastic nonlinearity has been shown to result in a dynamic nonlinear response which deviates from the known classical nonlinear response; hence this phenomenon was termed nonclassical nonlinearity. Metallic structures, which typically exhibit weak nonlinearity,… read more here.
