BaZnGa T-shirt design. BaZnGa (barium zinc gallide) is a ternary compound of barium, zinc, and gallium that was inspired by the saying "Bazinga!" from Sheldon Cooper on The Big Bang Theory television series. [1] It is a poor metal. BaZnGa crystals can be grown by adding gallium to a BaZn eutectic at 800° C and then cooling to 400 °C. Hot ...
Jim Parsons is known mostly for his incredible portrayal of the socially awkward theoretical physicist, Sheldon Cooper, on the CBS smash hit "The Big Bang Theory". His "Sheldonisms" circulate on ...

In IUPAC nomenclature of chemistry, a pendant group (sometimes spelled pendent) or side group is a group of atoms attached to a backbone chain of a long molecule, usually a polymer. Pendant groups are different from pendant chains, as they are neither oligomeric nor polymeric. [2] For example, the phenyl groups are the pendant groups on a ...
Bazinga" is the catchphrase used by Sheldon Cooper of The Big Bang Theory. Bazinga may also refer to: Bazinga rieki, a jellyfish genus; Euglossa bazinga, a species of ...
Barium oxide, also known as baria, is a white hygroscopic non-flammable compound with the formula BaO. It has a cubic structure and is used in cathode-ray tubes, crown glass, and catalysts.
Barium bromide is a precursor to chemicals used in photography and to other bromides. Historically, barium bromide was used to purify radium in a process of fractional crystallization devised by Marie Curie.
Barium thiocyanate is prepared by mixing barium hydroxide and ammonium thiocyanate in water. [4]2 NH 4 SCN + Ba(OH) 2 → Ba(SCN) 2 + 2 NH 3 + 2 H 2 O. According to X-ray crystallography, the anhydrous salt is a coordination polymer.
