MXene (Ti 2 CT x ) is exfoliated in a vortex fluidic device (VFD), as a thin film microfluidic platform, under continuous flow conditions, down to ca 3 nm thin multi-layered two-dimensional (2D) material, as determined using AFM. The optimized process, under an inert atmosphere of nitrogen to avoid oxidation of the material, was established by systematically exploring the operating parameters of the VFD, along with the concentration of the dispersed starting material and the choice of solvent, which was a 1 : 1 mixture of isopropyl alcohol and water. There is also some fragmentation of the 2D material into nanoparticles ca 68 nm in diameter.

Metathesis Catalysts

Ruthenium-catalysed ethenolysis occurs in a vortex fluidic device (VFD) – a scalable, thin-film microfluidic continuous flow process. This process takes advantage of the efficient mass transfer of gaseous reagents into the dynamic thin film of liquid. Also reported is the rapid quenching of the ruthenium-based olefin metathesis catalyst by the addition of a saturated solution of N-acetyl-l-cysteine in MeCN, as a convenient alternative to previously reported quenching methods.

Lanthanide phosphate nanoparticles were co-precipitated under continuous flow in a vortex fluidic device in the presence of polyvinylpyrrolidone (PVP) of different molecular weights and at varying rotational speeds and tilt angles. Dandelion-shaped lanthanide phosphate particles were produced at rotation speeds of 5000 rpm and 7000 rpm. In contrast, individual rods formed at 9000 rpm. Transition electron microscope images reveal changes in morphology of the dandelion-shaped nanoparticles with changes in the chain length of PVP or tilt angle of the tube of the vortex fluidic device. These morphological changes are likely to arise from different wrapping and aggregation of the nanoparticles induced by the PVP polymer under shear.
