Efficient extraction of a radionuclide (Sr 2+ ) in the presence of the similar ion Ca 2+ is a major challenge in nuclear waste management. In article e25418, Bandyopadhyay et al., using free energy corrected DFT, propose a two‐step Sr 2+ extraction methodology in nitrate media in the presence of Ca 2+ , with the help of a new‐generation multitopic ion pair receptor. The calculated ion‐exchange free energies suggest that once [Sr(NO 3 ) 2 ] is extracted in organic media, the receptor's high affinity toward K + can be used to back‐strip Sr 2+ to the aqueous phase. Thus, the proposed receptor is suggested to be a promising material for Sr 2+ ion extraction. (DOI: 10.1002/qua.25418 ).
