Different Re3+ ion (Re = Y, Eu, La, Sm, Tb, Pr) influence on the product during synthesis process.
Quantitative analysis of metal ions was achieved in this study for elements Ag, Au, Ba, Cd, Cr, Cu, Eu, La, Mn, Ni, Pb, Sr and Y.
Rare-earth nitrate solutions [Re(NO3 3 (Re = Y, Eu, La, Sm, Tb, Pr)] with a concentration of 0.04 to 0.08 mol/L were prepared by ourselves.
Multifunctional SiO2 · Re2O3 (Re = Y, Eu, La, Sm, Tb, Pr) hollow spheres (HSs) have been fabricated using an acidic Re3+ ion solution.
By keeping other reaction conditions unchanged such as the pH value of the solution, reaction time, and reaction temperature, the influence of different Re3+ ions (Re = Y, Eu, La, Sm, Tb, Pr) on the structure of the as-prepared products was investigated (see Additional file 1: Table S2 and Figure S4).

Considering parts and components suppliers, we verify that imports from the ROW, EU, EA, LA, and North America promoted an increase in the sophistication of the final products traded inside Latin America.

A fixed-bed study was carried out by using cells of Pseudomonas aeruginosa immobilized in polyacrylamide gel as a biosorbent for the removal of lanthanide (La, Eu, Yb) ions from aqueous solutions.
