Devices and methods for preparing a slurry for coating onto a substrate. The devices and methods of the present disclosure relate to providing a slurry in a closed volume with at least one passage. The slurry includes a solvent, a powder, and a binder. The slurry can also include a dispersion agent. The slurry is forced repeatedly under high pressure through the at least one passage in a first flow direction and then back through the at least one passage in a second flow direction, opposite the first flow direction. The forcing homogenously disperses the powder and the binder within the solvent. Both sides of the substrate are then coated simultaneously with the slurry extruded from the closed volume after the forcing. Curing of the coated slurry includes freeze drying to preserve the porosity of the slurry on the substrate.

Provided in one embodiment is a method of making, comprising: exposing a raw material having a first viscosity to a first pressure and a first temperature such that the raw material after the exposure has a second viscosity, wherein the raw material comprises particles comprising at least one electrically conductive material, and wherein the second viscosity is sufficiently low for the raw material to be adapted for a hydrodynamic cavitation process; and subjecting the raw material having the second viscosity to the hydrodynamic cavitation process to make a product material having a third viscosity. Apparatus employed to apply the method and the exemplary compositions made in accordance with the method are also provided.

The invention relates to a device (12) for mixing/dosing liquid coating materials, in particular for use in a coating system (10) for spectacle lenses, said device having at least a first and a second storage container (14-24) for liquid starting materials, a conveying device (26) for sucking in and expelling liquids, a mixing container (28), and a liquid outlet (30) for mixed/dosed liquid coating materials.

Systems, apparatuses, and methods for making content liquid foamy for discharge are described herein. A dispenser for making content liquid discharge foamy by mixing air flow from an air chamber with the content liquid flow from a liquid chamber can be provided. The dispenser can comprise a mixing chamber configured to mix air and content liquid; a porous member between an air passage from the air chamber and the mixing chamber; and a liquid passage from the liquid chamber to the mixing chamber. The liquid passage can have a first liquid passage and a plurality of second liquid passages. The liquid passage can be configured such that content liquid flows from the first liquid passage to the second liquid passages to the mixing chamber. The second liquid passages can be configured to provide flow of the content liquid in at least two directions.
