Abstract: Emulsion breaking and phase separation is achieved by droplet adhesion. An emulsion breaking device includes a channel having distinct adjacent zones with distinctly different surface wettability characteristics, namely, solvophilic and solvophobic surfaces. The device is positioned such that the upstream portion of the device is configured to be wetted by the continuous phase of the emulsion, and the downstream portion of the device is configured to be wetted by the dispersed phase of the emulsion. As the emulsion flows from the upstream zone to the downstream zone, the change in surface wettability characteristics promotes adhesion of the dispersed phase as the dispersed phase wets the surface of the downstream portion of the channel, which results in breaking of the emulsion. Subsequent collection of the broken emulsion in a collection vessel results in separation of the disparate phases to facilitate their recapture and recycling.

Abstract: A method of dispersing graphene and graphitic nanomaterials uses a multiphase fluid dynamic technique. The method includes a device, incorporating a high intensity fluid dynamics technique, controlling the expansion and compression ratio of the working stream that leads to an effective dispersion of the nanomaterial in the matrix.

Abstract: The present disclosure relates to a hydrolysate of a mixture of lignocellulosic biomass and seaweed biomass. By mixing seaweed biomass with lignocellulosic biomass and then preparing a hydrolysate, lignocellulosic biomass-derived acetic acid is consumed together with seaweed biomass-derived mannitol.
