A gas-mixing device is provided for the controlled mixing of two different gases. The gas-mixing device has a first inlet for a first gas which is under pressure, a second inlet for a second gas which is under pressure, and an outlet for the mixed gas. The gas-mixing device also has two gas-conducting lines. The first line connects the first inlet to the outlet, and the second line connects the second inlet to the outlet. In each line, an upstream valve, a proportional valve and a flow sensor are provided. The gas-mixing device additionally has at least one electronic control unit for controlling the two proportional valves and is designed such that the proportional valve of the first line acts as a pressure regulator and the proportional valve of the second line acts as a flow regulator.

The present application relates to a silicon-based negative electrode slurry, a preparation method therefor and a negative electrode piece. The preparation method comprises: (1) mixing CMC and a solvent to obtain a primary adhesive solution; (2) mixing PAA, a silicon-based negative electrode material, a conductive agent, a solvent, and the obtained adhesive solution, then performing double planetary mixing to obtain a secondary glue solution; (3) mixing a solvent and the obtained secondary adhesive solution to obtain a coarse slurry; and (4) mixing the SBR and the obtained coarse slurry to obtain a silicon-based negative electrode slurry. In the homogenization method of the present application, after the PAA and the SBR are incorporated in separate steps, a three-dimensional cross-linked network can be formed, good tensile behavior is exhibited, a bonding effect is improved, same can adapt well to volumetric expansion of silicon negative electrodes, and the cycling stability of silicon negative electrodes is improved.

The present disclosure relates to a method for converting carbon dioxide into carbon monoxide comprising: producing atomic oxygen, providing carbon dioxide to be converted, mixing the carbon dioxide with the atomic oxygen within a mixing area such that the atomic oxygen can interact with the carbon dioxide for forming carbon monoxide within the mixing area through a first CO producing reaction: C0.sub.2+0.fwdarw.C0+02, supplying the atomic oxygen into the mixing area at a first supply rate and supplying the carbon dioxide into the mixing area at a second supply rate, defining the first supply rate and the second supply rate such that a ratio between the first supply rate and the second supply rate remains within a pre-defined lower and upper threshold, and extracting carbon monoxide from the mixing area. The present disclosure also relates to an apparatus for converting carbon dioxide into carbon monoxide.

Disclosed is a drinking system (1) with a drinking vessel (2) defining a receiving chamber (3) for a liquid, a drinking straw (4) arranged on the drinking vessel (2), projecting from the drinking vessel (2) and guided into the receiving chamber (3), with a first end having an inlet opening (5) which projects towards a base of the receiving chamber (3), and with a second end having a drinking opening (6), and with a suction channel (7) between the inlet opening (5) and the drinking opening (6), and an aroma reservoir (8) connected with the drinking straw (4) via an inflow channel (9).

According to the invention, the drinking system is characterized in that the aroma reservoir (8) contains a liquid aroma medium which contains fragrances and/or flavorings in dissolved or emulsified and thus diluted form and which, when liquid is sucked from the drinking vessel (2) through the drinking straw (4), is sucked through the inflow channel (9) into the drinking straw (4) and is mixed there with the liquid sucked into the drinking straw (4) from the drinking vessel (3).

A laboratory testing system includes a shear mixer and an intermediate container sized to surround a mixing component of the shear mixer therein. The intermediate container includes an opening at an upper end, a lower surface, one or more side walls extending upward from the lower surface and a port extending through a wall of the one or more side walls or through the lower surface. The port provides access to the intermediate container for removal of a portion of a fluid mixture from the intermediate container during mixing of the fluid in the intermediate container by the shear mixer.

According to an example, a mixing device comprises a first chamber including a solute addition member and a first mixer, a second chamber including a second mixer, a printing fluid pump, and a controller operatively connected to the solute addition member, the pump, the first mixer, and the second mixer. The controller is to control the pump to move printing fluid towards the printing fluid tank based on a printing fluid density level in the printing fluid tank, to control the solute addition member to add solids based on the printing fluid density level, and to control the first mixer and the second mixer to mix the added solids with the printing fluid moved by the pump.
