Giant effective liquid-self diffusion in stagnant liquids by magnetic nanomixing

► MNPs maneuvered at inaccessible spatial scales using external magnetic field. ► Spinning MNPs under RMF transfers momentum to the surrounding liquid molecules. ► Excited MNPs augment liquid self-diffusion coefficient in a stagnant-liquid containing capillary. ► Magnetically-induced nanoconvection intensifies transport beyond molecular diffusion.
