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 ...
Barium azide can be used to make azides of magnesium, sodium, potassium, lithium, rubidium and zinc with their respective sulfates. [4]Ba(N 3) 2 + Li 2 SO 4 → 2 LiN 3 + BaSO 4. It can also be used as a source for high purity nitrogen by heating:
Barite in the water column, known as marine or pelagic barite, reveals information on seawater chemistry variation over time. [26] Barite in sediments, known as diagenetic or cold seeps barite, gives information about sedimentary redox processes. [ 26 ]
Barium acetate was featured in a 2001 episode of the television series Forensic Files, recounting the 1993 murder of a man by his teenage daughter (Marie Robards), though the episode and other crime documentary shows examining the Robards case excluded mention of the name of the chemical.
Barium sulfide is the inorganic compound with the formula Ba S.BaS is the barium compound produced on the largest scale. [3] It is an important precursor to other barium compounds including barium carbonate and the pigment lithopone, ZnS/BaSO 4. [4]
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.
Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds that display high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen [77 K (−196.2 °C; −321.1 °F)] at about 93 K (−180.2 °C; −292.3 °F).
