  2. Orthoborate - Wikipedia

    en.wikipedia.org/wiki/Orthoborate

    The orthoborate ion is known in the solid state, for example, in calcium orthoborate (Ca 2+) 3 ([BO 3] 3−) 2, [1] where it adopts a nearly trigonal planar structure. It is a structural analogue of the carbonate anion [CO 3] 2−, with which it is isoelectronic. Simple bonding theories point to the trigonal planar structure.

    en.wikipedia.org/wiki/List_of_binary_codes

    This is a list of some binary codes that are (or have been) used to represent text as a sequence of binary digits "0" and "1". Fixed-width binary codes use a set number of bits to represent each character in the text, while in variable-width binary codes, the number of bits may vary from character to character.

    en.wikipedia.org/wiki/Borate

    A borate is any of a range of boron oxyanions, anions containing boron and oxygen, such as orthoborate BO 3− 3, metaborate BO − 2, or tetraborate B 4 O 2− 7; or any salt of such anions, such as sodium metaborate, Na + [BO 2] − and borax (Na +) 2 [B 4 O 7] 2−.

    In mathematics and computer science, the binary Goppa code is an error-correcting code that belongs to the class of general Goppa codes originally described by Valerii Denisovich Goppa, but the binary structure gives it several mathematical advantages over non-binary variants, also providing a better fit for common usage in computers and ...

    en.wikipedia.org/wiki/Corundum_(structure)

    When A is nonmetallic and B is metallic, the structure becomes the antiphase of corundum, called the anticorundum structure type, [8] with examples including β-Ca 3 N 2 [9] and borates. Ternary and multinary compounds can also exists in the corundum structure. The corundum-like structure with the composition A 2 BB'O 6 is called double ...
