Ti-6Al-4V (UNS designation R56400), also sometimes called TC4, Ti64, [1] or ASTM Grade 5, is an alpha-beta titanium alloy with a high specific strength and excellent corrosion resistance.
The Co–CO and Co–H bond distances were determined by gas-phase electron diffraction to be 1.764 and 1.556 Å, respectively. [6] Assuming the presence of a formal hydride ion, the oxidation state of cobalt in this compound is +1. But unlike some other transition-metal hydrides complexes, HCo(CO) 4 is highly acidic, with a pK a of 8.5. [7]
Cobalt(II) hydride is an inorganic compound with a chemical formula CoH 2. It has dark grey crystals. It oxidizes slowly in air and reacts with water. [1] [2] Two forms of cobalt(II) hydride exist under high pressure. From 4 to 45 GPa there is a face-centred cubic form with formula CoH.

It was found that the complex would quickly carbonylate and that the catalytic activity of the resulting material was enhanced by a variety of additives but inhibited by halides. This inhibition did not occur in the presence of base, suggesting that the hydrido-complex represented the catalytic form of the complex.
Rhodizonic acid is a chemical compound with formula H 2 C 6 O 6 or (CO) 4 (COH) 2. It can be seen as a twofold enol and fourfold ketone of cyclohexene, more precisely 5,6-dihydroxycyclohex-5-ene-1,2,3,4-tetrone. Rhodizonic acid is usually obtained in the form of a dihydrate H 2 C 6 O 6 ·2H 2 O.
Turning is a term used when referring to moving the level to take an elevation shot from a different location. To "turn" the level, one must first take a reading and record the elevation of the point the rod is located on. While the rod is being kept in exactly the same location, the level is moved to a new location where the rod is still visible.
Monolith Inc. (formerly Boxer Industries) is an American chemical and materials producer based in Nebraska. The company is known for being the first company to use methane pyrolysis to split natural gas into carbon and hydrogen gas on a commercial scale.
