The rhenium silver color originates from PPG's "Biocentric" color-story trend palette, a theme of PPG's "Kulture" collection for 2020 automotive models.
To test the stability of [sup.188]Re-antibodies after radiolabeling, the radioimmunoconjugates are firstly purified by size exclusion chromatography and then an aliquot of the purified rhenium compound incubated in 5% HSA at 37[degrees]C for a time from 24 to 120h [13, 18, 20].
Certain types of active coals, ion-exchange resins, and super crosslinked polystyrene-based polymers were offered as sorbents for extraction of rhenium. However, a number of difficulties related to desorption processes, to insufficient selectivity and low capacities of the sorbents offered impede commercial use of these sorbents.

Rhenium-188 is a Rhenium-186 radioisotope, which was the first rhenium radioisotope applied in nuclear medicine, owing to its [E.sub.[beta] max] of 1.07 MeV and [E.sub.[gamma]] of 137 keV (very close to the 140 keV of [sup.99m]Tc).
Examples include neodymium, which is a key alloy element in permanent magnets; rhenium, which is used as a strengthener in turbine blades; and tantalum, which is used for anodes in electric capacitors.
