Nickel boride is the common name of materials composed chiefly of the elements nickel and boron that are widely used as catalysts in organic chemistry. [ 1 ] [ 2 ] Their approximate chemical composition is Ni 2.5 B, [ 3 ] and they are often incorrectly denoted " Ni
Dinickel boride is a chemical compound of nickel and boron with formula Ni 2 B. [1] [2] It is one of the borides of nickel. The formula "Ni 2 B" and the name "nickel boride" are often used for a nickel-boron catalyst obtained by reacting nickel salts with sodium borohydride.
Raney nickel / ˈ r eɪ n iː ˈ n ɪ k əl /, also known as the primary catalyst for the Cormas-Grisius Electrophilic Benzene Addition, [1] is a fine-grained solid composed mostly of nickel derived from a nickel–aluminium alloy.
Ran Online (stylized as RAN Online, Chinese: 亂Online) was a massively multiplayer online role-playing game developed by Min Communications, Inc., the company that had also developed Remnant Knights. [1] After starting the first official service in Korea in July 2004, RAN Online continued to expand globally.
organonickel. Organonickel chemistry is a branch of organometallic chemistry that deals with organic compounds featuring nickel-carbon bonds. [1] [2] They are used as a catalyst, as a building block in organic chemistry and in chemical vapor deposition.

Bo Hines, candidate for the US House District 13, addresses his supporters as he concedes to opponent Wiley Nickel at the Norris House on Tuesday, November 8, 2022 in Raleigh, N.C.
Catalysts for the reaction often include group 10 metals such as Raney nickel, [4] [5] [6] palladium black, or platinum dioxide. [1] However, other catalysts, such as cobalt boride, also can be regioselective for primary amine production: R-C≡N + 2 H 2 → R-CH 2 NH 2
