A process for producing paper or board, which process comprises ad-mixing (I) an aqueous composition of pH ≦6 and (II) at least one water-soluble polymeric anionic compound to a paper stock having a pH in the range from 6 to 8 and then dewatering the paper stock by sheet formation and drying, wherein the aqueous composition comprises (a) polymers having primary amino groups and/or amidine groups to a combined content for these groups of ≧1.5 meq/g of polymer, and (b) 0.01 to 50 mol % of 1,4-cyclohexanedione (b) based on the combined amount of primary amino groups and/or amidine groups of the polymers, and also to the paper or board thus obtained.

Method for making a liquid foam from graphene. The method includes preparing an aqueous dispersion of graphene oxide and adding a water miscible compound to the aqueous dispersion to produce a mixture including a modified form of graphene oxide. A second immiscible fluid (a gas or a liquid) with or without a surfactant are added to the mixture and agitated to form a fluid/water composite wherein the modified form of graphene oxide aggregates at the interfaces between the fluid and water to form either a closed or open cell foam. The modified form of graphene oxide is the foaming agent.

A storage and mixing device for two-component polymethyl methacrylate bone cements having a cylindrical interior of a cartridge that is delimited on a front side by a cartridge head, a plunger arranged to be axially movable in the cylindrical interior of the cartridge and spaced from the cartridge head, a powdery first parent component of the bone cement, that is contained in the interior between the plunger and the cartridge head, a feed-through arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head. The feed-through is connectable to a fluid line, a receptacle for a monomer liquid, wherein the fluid line connects the feed-through to the receptacle in a liquid-permeable manner, and a press-out device pushable into the receptacle, so that monomer liquid is pressable out of the receptacle into the fluid line. The plunger (2) is spaced from a back side of the cylindrical interior, located opposite the front side, so that, by moving the plunger in the direction of the back side, the press-out device is pushable into the receptacle and a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head.

A storage and mixing device for PMMA bone cements having a cylindrical interior of the cartridge that is delimited on a front side by a cartridge head with a closed delivery opening, a plunger which is arranged to be axially movable in the cylindrical interior of the cartridge and which is spaced from the cartridge head. The plunger circumferentially rests against the inner wall of the interior, so that the plunger divides the interior of the cartridge into two sections in a gas-tight manner, a powdery first parent component of the bone cement, which is contained in the interior between the plunger and the cartridge head, a feed-through which is arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head, wherein the feed-through is connected to a fluid line in which a monomer liquid as a second parent component of the bone cement is contained or into which a monomer liquid is fillable or introducible. A filter is arrangeable in the cartridge head, in the feed-through and/or in the fluid line, wherein the filter is permeable to the monomer liquid and impermeable to the first parent component, wherein the plunger is spaced from a back side of the cylindrical interior, located opposite the front side, to an extent that, by moving the plunger in the direction of the back side, a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head, wherein the reduced pressure is able to suck the monomer liquid out of the fluid line into the interior of the cartridge.
