  2. Bromocresol green - Wikipedia

    en.wikipedia.org/wiki/Bromocresol_green

    Bromocresol green (BCG) is a dye of the triphenylmethane family (triarylmethane dyes). It belongs to a class of dyes called sulfonephthaleins. [4] It is used as a pH indicator in applications such as growth mediums for microorganisms and titrations. In clinical practise, it is commonly used as a diagnostic technique.

  3. Superhard material - Wikipedia

    en.wikipedia.org/wiki/Superhard_material

    Cubic boron nitride adopts a sphalerite crystal structure, which can be constructed by replacing every two carbon atoms in diamond with one boron atom and one nitrogen atom. The short B-N (1.57 Å) bond is close to the diamond C-C bond length (1.54 Å), that results in strong covalent bonding between atoms in the same fashion as in diamond.

  4. Borocarbonitrides - Wikipedia

    en.wikipedia.org/wiki/Borocarbonitrides

    A schematic of borocarbonitride (BCN) Borocarbonitrides are two-dimensional compounds that contain boron, nitrogen, and carbon atoms in a ratio BxCyNz. [1] [2] Borocarbonitrides are distinct from B,N co-doped graphene in that the former contains separate boron nitride and graphene domains as well as rings with B-C, B-N, C-N, and C-C bonds. [3]

  5. β-Carbon nitride - Wikipedia

    en.wikipedia.org/wiki/Β-Carbon_nitride

    β-Carbon nitride (beta-carbon nitride), β-C 3 N 4, is a superhard material predicted to be harder than diamond. [ 2 ] The material was first proposed in 1985 by Amy Liu and Marvin L. Cohen .

    en.wikipedia.org/wiki/Carbon_nitride

    Beta carbon nitride - a solid with a formula β-C 3 N 4, which is predicted to be harder than diamond. Graphitic carbon nitride - g-C 3 N 4, with important catalytic and sensor properties. [2] Dicyanodiazomethane (NC) 2 C=N=N, the only C 3 N 4 isomer studied experimentally; Tricyanamide N(CN) 3 - C 3 N 4 monomer (has never been prepared yet)

  7. Manganese nitrides - Wikipedia

    en.wikipedia.org/wiki/Manganese_nitrides

    Manganese nitrides are salts of manganese and the nitride ion. Four of these compounds are stable at atmospheric pressure.The most important is Mn 3 N 2, which catalyzes nitrogen fixation and is a high-temperature antiferromagnet.

    en.wikipedia.org/wiki/Borazon

    In Ivan Yefremov's novel Andromeda: A Space-Age Tale (written 1954–1956, published Jan 1957) boron nitride named borazon is routinely used in sublight engine parts and spaceship surface coating. In Randall Garrett's 's short story "Thin Edge" (Analog, Dec 1963) [ 5 ] a fictional borazon-tungsten cable of extraordinary tensile strength is a ...
