Ab Initio Molecular Dynamics Study of Quadrupolar Spin Relaxation in an Ionic Liquid
Journal of Computational Chemistry, Volume 47, Issue 3, 30 January 2026.This study presents a methodology for describing the relaxation of nuclear spins (with I > 1/2), applicable to ionic liquids of a general nature. Based on ab initio molecular dynamics, we demonstrate the importance of explicit solvation in calculating the relaxation times of the quadrupolar mechanism.

18F‐Radiopharmaceutical Diversification Enabled by Deaminative Cross‐Electrophile Couplings
Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.A general Ni‐mediated (C)sp2–(C)sp3 cross‐coupling expedites access to 18F‐radiopharmaceuticals, essential for positron emission tomography imaging and drug discovery. This late‐stage diversification approach was implemented across three user‐friendly automated protocols affording 18F‐radiotracers in sufficient quantities for imaging.
