TL;DR: In this article, stable structures and stoichiometries of binary Mg-N compounds are explored at pressures from ambient up to 300 GPa using ab initio evolutionary simulations.
Abstract: Stable structures and stoichiometries of binary Mg–N compounds are explored at pressures from ambient up to 300 GPa using ab initio evolutionary simulations. In addition to Mg3N2, we identified five nitrogen-rich compositions (MgN4, MgN3, MgN2, Mg2N3, and Mg5N7) and three magnesium-rich ones (Mg5N3, Mg4N3 and Mg5N4), which have stability fields on the phase diagram. These compounds have peculiar structural features, such as N2 dumbbells, bent N3 units, planar SO3-like N(N)3 units, N6 six-membered rings, 1D polythiazyl S2N2-like nitrogen chains, and 2D polymeric nitrogen nets. The dimensionality of the nitrogen network decreases as magnesium content increases; magnesium atoms act as a scissor by transferring valence electrons to the antibonding states of nitrogen sublattice. In this context, pressure acts as a bonding glue in the nitrogen sublattice, enabling the emergence of polynitrogen molecule-like species and nets. In general, Zintl–Klemm concept and molecular orbital analysis proved useful for ration...

TL;DR: In this article, the authors describe some of the recent work on the electrochemical and electrode applications of polymers which can be switched to an electrically conductive state, as well as the inherently conductive (SN)x.
Abstract: This report describes some of the recent work on the electrochemical and electrode applications of polymers which are electroactive and can be switched to an electrically conductive state, as well as the inherently conductive (SN)x. The materials fall into two general categories. There are the polymer films which can be prepared in situ by the electrochemical polymerization of aromatic compounds, and there are the polyenes such as polyacetylene and polythiazyl. Many of the electrode applications being considered are based on the electroactive/conductive properties of the films such as display devices, and storage batteries. Some applications make use of the conductive property of the materials such as protective coatings against corrosion, and other applications make use of the possibility for molecular selectivity such as chemically selective electrodes and sensors.

TL;DR: In this paper, it was shown that the other alternative structures taken into account (sym-triazine based and polyazomethine with sulfur bridges) are not likely the correct ones for parathiocyanogen.
Abstract: New data from 13C-NMR spectrometry as well as from FT-IR, UV-VIS, X-ray diffraction pattern, and thermal stability (TGA, DTA) confirm that parathiocyanogen or polythiocyanogen (SCN)x has a linear structure analogous to that assigned to polythiazyl or polysulfurnitride, (SN)x. Based also on the chemical reaction of (SCN)x with NaCN and Na2S, it is shown that the other alternative structures taken into account (sym-triazine based and polyazomethine with sulfur bridges) are not likely the correct ones for parathiocyanogen.
