0 a chemical element that is a silver-grey metal, used to make steel alloys (= mixtures of metals) and in ceramics (= making objects out of baked clay) -- (金屬)釩
In the blanket, the tubing is made of vanadium alloy.
The same is true for the vanadium, rubidium and zirconium concentrations in the sediment.
However, carbon, and oxygen are still present in quantity and acquire energy that could have been transferred to the vanadium, limiting the efficiency.
Nitrogenase is a metalloenzyme, and the three known forms require molybdenum, vanadium or iron at a particularly important catalytic site.
The remaining nine, which are present in small quantities, are the d-block elements vanadium, chromium, molybdenum, manganese, iron, cobalt, nickel, copper and zinc, and are known as the trace metals.
These minerals include uranium, manganese, chrome, vanadium, platinum, gold, industrial diamonds, and so on.
As it is such fine material, part of that dust will be heavy metals such as vanadium and mercury.
I understand that cobalt, copper, iron, lead, manganese, molybdenum, nickel, vanadium and zinc, in varying quantities, may be available.
