Vortex-assisted electroosmotic mixing of Carreau fluid in a microchannel.
Mehta SK, Mondal PK. Mehta SK, et al. Electrophoresis. 2023 Nov;44(21-22):1629-1636. doi: 10.1002/elps.202200258. Epub 2023 Mar 14. Electrophoresis. 2023. PMID: 36807917
We demonstrate that a substantial momentum difference between the microchannel's plane wall and cylinder leads to the development of a vortex in the flow pathway, which in turn, enhances mixing substantially. As shown, for a fluid having a highly shear-thinning nature, the …

Phase vortex lattices in neutron interferometry.
Geerits N, Lemmel H, Berger AS, Sponar S. Geerits N, et al. Commun Phys. 2023;6(1):209. doi: 10.1038/s42005-023-01318-6. Epub 2023 Aug 9. Commun Phys. 2023. PMID: 38665409 Free PMC article.
In this work we generalize magnetic methods which employ coherent averaging and apply this to neutron interferometry. Two aluminium prisms are inserted into a nested loop interferometer to generate a phase vortex lattice with significant extrinsic OAM, L(z) 0.35, on …
