Low-Compressibility Carbon Nitrides

Science, 1996
First-principles calculations of the relative stability, structure, and physical properties of carbon nitride polymorphs predict a cubic form of C 3 N 4 with a zero-pressure bulk modulus exceeding that of diamond.

Carbon nitride photocatalysts

2018
© 2018 Elsevier Ltd All rights reserved. Photocatalysis processes for producing alternative and sustainable energy through hydrogen evolution and CO2 reduction have secured a prominent position among all the renewable energy technologies. The emerging carbon-based photocatalyst, namely graphitic carbon nitride (g-C3N4), marks an important step toward ...

Polymeric Carbon Nitride Nanosheets

Journal of Macromolecular Science, Part B, 2012
Polymeric carbon nitride was synthesized by polycondensation in a nitrogen flux using melamine cyanurate as a reagent and sulfuric acid as a catalyst. The product was polymeric-graphitic carbon nitride based on heptazine units. The carbon nitride was composed of nanosheet flakes.

Polymerized carbon nitride nanobells

Journal of Applied Physics, 2002
Well-aligned carbon nitride nanotubes are fabricated by microwave plasma assisted chemical vapor deposition using iron as the catalyst. These nanotubes are linearly polymerized by carbon nitride nanobells with catalyst particles in the root, as revealed by high-resolution transmission electron microscopy.

Stability of Small Carbon-Nitride Heterofullerenes

Physical Review Letters, 2003
Carbon nitride nanostructures have been produced by the arc-discharge technique and analyzed by mass spectrometry. A series of structured peaks in the region of masses from 480 up to 600 suggests the existence of heterofullerenes C(n-x)Nx(40 < or = n < or = 50).

Investigations into carbon nitrides and carbon nitride derivatives

2013
Carbon nitrides and carbon nitride derivatives are promising photocatalysts. The main focus of this thesis is the synthesis and characterization of various carbon nitrides (incompletely condensed melon, carbon nitride doped cesium titanate, ultra-long calcined melon, and OH-melem).

Nanocluster's magnetron sputtering of carbon-nitride and hybrid nickel-carbon-nitride films

2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP), 2017
High argon and nitrogen gas pressure and low plasma power has been used to produce carbon nitride (CN x ) and nickel carbon nitride (Ni@CN x ) films by reactive dc magnetron sputtering. Under these conditions, the growth of the film occurs as a process of precipitation of clusters of sputtered material, rather than individual atoms.

Research on carbon nitrides

Progress in Materials Science, 1997
The status of research on carbon nitride compounds is reviewed including exciting recent results. On the basis of the early theoretical predictions by Cohen and co-workers in 1985-1990, covalent carbon nitrides should be as hard as diamond. The high hardness, high wear resistance and low coefficient of friction make it attractive for industrial ...

Diamondlike Carbon, Carbon Nitride, and Titanium Nitride Coatings on Metal and Polymer Substrates

MRS Proceedings, 1998
AbstractWe have deposited diamondlike carbon, carbon nitride, and titanium nitride biocompatible coatings using pulsed laser deposition and magnetron sputtering on metallic (cobalt-chromium and titanium- 6% aluminum- 4% vanadium) and polymeric (high-density polyethylene) substrates commonly used in human prosthetic devices.
