Recent progress in the synthesis and characterization of amorphous and crystalline carbon nitride coatings

3,6‐Di(azido)‐1,2,4,5‐Tetrazine: A Precursor for the Preparation of Carbon Nanospheres and Nitrogen‐Rich Carbon Nitrides

“…Synthesis of DiAT (1) able 3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine (2; 2.0 g, 7.4 mmol) [17] rapidly reacted with hydrazine hydrate (0.78 g, 15.6 mmol) to give 3,6-di(hydrazino)-1,2,4,5-tetrazine (DHT, 3), [18] which underwent diazotization in 3 m HCl at 0 8C to yield 1. [19] The isolated sample of 1 was characterized by X-ray crystallography, [20] differential scanning calorimetry (DSC); cyclic voltammetry; and IR, UV/Vis, and 13 C NMR spectroscopy.…”

P272: Nuchal cord, induction of labour and caesarean section

“…Carbon nitrides are of current interest due to their novel mechanical, optical, and tribological properties including low density, surface roughness, wear resistance, chemical inertness, and biocompatibility 1–4. These superhard diamondlike materials promise a variety of technological and biological applications, for example, biocompatible coatings on biomedical implants,5–6 battery electrodes,7–8 gas‐separation systems,9 corrosion protection,10 and humidity and gas sensors 11. As these applications are primarily governed by the particle size, material texture, and nitrogen content, an extensive effort has focused on the discovery of precursors along with appropriate methods to control the size, regulate the texture, and increase the nitrogen content of carbon nitrides.…”

For example, they are used as biocompatible coatings on biomedical implants,8–9 battery electrodes,10 catalytic supports,11 gas separation systems,12 electronic materials,13 and humidity and gas sensors 14. Unlike carbon‐based materials, applications of carbon nitrides are not only governed by the texture and size of the particles13 but also by the relative nitrogen content.…”
