Abstract: The present disclosure relates to coatings. For example, some embodiments may include methods for producing a coating comprising: depositing a metallic matrix on a substrate by electrochemical deposition using a deposition bath including carbon comprising particles and oxide particles dispersed therein; wherein the carbon comprising particles are embedded into the metallic matrix and pores are distributed in the coating; wherein at least 80% of the pores have a pore diameter in a range from 3 to 30 ?m; wherein oxide particles are incorporated into and fixed in the pores during deposition and the oxide particles remain partially uncoated by the material of the metallic matrix.

Abstract: The invention relates to a novel electrolytic process for removing impurities from the inner surface of a metallic container. The process is particularly useful for cleaning process reactors used for culturing microorganisms, and storage tanks used for storing metabolites formed in the process reactor, as well as containers for dairy products.

Abstract: A roller assembly in a wipe material dispenser has at least one pair of cooperating rollers arranged to feed the wipe material. The roller assembly comprises a first and a second roller, wherein each roller comprises a central longitudinal core on which is mounted a number of parallel and axially spaced discs. Each roller has regions of reduced diameter between adjacent discs, and the first and the second roller are located so that the axial location of the spaced discs on the first roller coincides with the regions of reduced diameter between adjacent discs on the second roller. A roller suitable for use in the roller assembly and a dispenser including such an assembly are also provided.
