Methods for mixing fluids including etanercept include providing a tank having an impeller with a 10 inch blade diameter disposed therein, filling a tank with a liquid composition comprising etanercept and one or more buffers to a level within the tank to cover the impeller, and operating the impeller to mix the liquid composition to a homogeneous state while maintaining a maximum shear stress imparted on the mixture of fluids at 125,000 s.sup.1 or below.

A puncture repair kit for repairing a puncture on an object includes a container containing a puncture repair fluid, a compressed air source for supplying compressed air, and a mixing device configured to be attached to the container to produce a mixture of the puncture repair fluid and the compressed air. The mixing device includes a mixing chamber for producing the mixture, a first inlet flow path configured to be connected to the compressed air source, a second inlet flow path for supplying the puncture repair fluid from the container to the mixing chamber, and an outlet flow path for discharging the mixture from the mixing chamber. The first inlet flow path includes a first opening for supplying the compressed air to the container, and a second opening for supplying the compressed air to at least one of the mixing chamber and the second inlet flow path.

Disclosed are methods of manufacturing negative electrode slurry for all-solid-state batteries, negative electrodes manufactured by the methods, and all-solid-state batteries including the negative electrodes. The method of manufacturing a negative electrode slurry includes preparing a first mixture by mixing a negative electrode material with a binder solution that includes a solvent and a first binder, producing a dispersion by performing an ultrasonic dispersion treatment on the first mixture, and preparing a second mixture by adding a second binder to the dispersion.
