  • Publication number: 20210310142
    Abstract: The present disclosure relates to a method of electroplating of a silver-graphene composite onto a substrate. The method comprises preparing a plating bath comprising: a dissolved water soluble silver salt, dispersed graphene flakes, and an aqueous electrolyte comprising a silver complexing agent, a cationic surfactant, and a pH adjusting compound. The zeta potential of the graphene-electrolyte interface in the plating bath is adjusted to be positive and within the range of 10-30 mV by means of the cationic surfactant and the pH adjusting compound. The method also comprises applying a negative electric potential on the substrate surface such that electrophoresis of the graphene flakes occurs and said flakes are co-deposited with the silver during electroplating thereof to form a silver-graphene composite coating on the substrate surface.

  • Publication number: 20200264140
    Abstract: Disclosed is a chromatography system (100) comprising: plural modules (1-25) including at least one pump and a column valve unit (8) connectable to plural chromatography columns; and a controller (600), the controller being operable to control the or each pump and the column valve to perform different chromatographic processes, including chromatography employing just one column, as well as chromatography employing two or more columns by selective valve opening in said unit. The system includes a housing (110) into which the plural modules (1-25) are interchangeably mountable in apertures of one generally vertical face of housing, the modules are adapted for selective fluidic interconnection by tubing substantially at said one face such that in use the modules and tubing occupy a generally vertically extending volume to minimize the footprint of the system.

  • Patent number: 10070618
    Abstract: The invention is directed to a milk conduit, a milk conduit device, a milk-receiving member and a milking member, wherein a milk conduit includes a first end portion for connection to a milk-receiving member, the first end portion including an inner sleeve section made of a first material and an outer sleeve section joined to the inner sleeve section and made of a second material, which is more rigid than the first material, and the outer sleeve section includes an outer peripheral surface and at least one projection extending outwardly from the outer peripheral surface, the projection having a peripheral extension of less than 180°, and engaged by a coupling member on the milk-receiving member.

  • Patent number: 9861069
    Abstract: A claw (C) for a milking machine includes an enclosure having an upper part (1) and a lower part (2) and enclosing an inner space (3) for a milk flow during a milking operation. The lower part includes a bottom surface (4) facing the inner space. An outlet nipple (12), connected to a long milk conduit (13), extends outwardly from the upper part. A suction tube (20) connects the inner space to the outlet nipple, and includes a lower tube section close to the bottom surface. Three support legs extend from the lower tube section and abut the bottom surface, thereby forming a gap between the lower tube section and the bottom surface. Each support leg has an end point, which end points are located in a common lower plane. The common lower plane is inclined to the center axis.

  • Patent number: 5603997
    Abstract: The present invention relates to a packaging material for reduced transfer from a package to its content of substances causing undesirable taste and/or hazardous substances, this reduction being due to the packaging material containing a hydrophobic zeolite. More specifically, the invention concerns paperboard, in which case the substances causing undesirable taste mainly are naturally occurring extractive substances, oxidation products thereof and, to a lesser extent, the paper chemicals present. Further, the presence of a hydrophobic zeolite in the paperboard enhances the water-repellent (hydrophobic) capacity. Also, the present invention concerns a method for production of a packaging material of paper, board or paperboard by forming and dewatering a suspension of lignocellulose-containing fibres, where the dewatering takes place in the presence of a hydrophobic zeolite.
