Niobium has physical and chemical properties similar to those of the element tantalum, and the two are therefore difficult to distinguish.
Brazil is the leading producer of niobium and ferroniobium, an alloy of niobium and iron. Niobium is used mostly in alloys, the largest part in special steel such as that used in gas pipelines. Although alloys contain only a maximum of 0.1%, that small percentage of niobium improves the strength of the steel. The temperature stability of niobium-containing superalloys is important for its use in jet and rocket engines. Niobium is used in various superconducting materials
A common use for cobalt(II) chloride was for the detection of moisture. A concentrated aqueous solution is red at room temperature, but becomes blue when heated.

N,N-Dimethyltryptamine is a psychedelic compound.[DMT occurs in trace amounts in mammals, including humans, where it putatively functions as a trace amineneurotransmitter/neuromodulator.
When ingested, DMT acts as a psychedelic drug. Depending on the dose and method of administration, its subjective effects can range from short-lived milder psychedelic states to powerful immersive experiences; these are often described as a total loss of connection to conventional reality with the encounter of ineffable spiritual/alien realms.
