Disclosed are a paddle discarding fully-sealed cement stirring and solidification bucket and a liquid injection and stirring method. A stirring paddle, a bucket cover, and a stirring steel bucket are first assembled and conveyed to a feeding station for cover removal and cement filling; then the stirring steel bucket is conveyed to a stirring station; after a stirring power device, a waste liquid injection device, and a breathing and exhaust device are correspondingly connected to a stirring paddle drive connection end, a waste liquid injection interface, and a breathing and exhaust device interface, injection and stirring of radioactive waste liquid are carried out in a fully-sealed environment. In the present invention, the stirring paddle is discarded in the steel bucket, thereby avoiding the problems of secondary radioactive waste liquid produced by cleaning the stirring paddle and diffusion of radioactive aerosol in the stirring process.

A device for use as a mixing apparatus comprising a container having a cross-section of at least 5 mm diameter, the cross-section being spanned by a wall having protrusions projecting into the cross-section, the protrusions preferably being distributed over the entire wall, the container being driven to reciprocate along a path curve obtainable by superimposing the movement along at least two axes lying at an angle to each other and preferably in the plane of the cross-section of the container at different frequencies.

A system to produce a mixture of fluids includes a pressure source, a pressure regulator, at least a first container containing a first fluid and a second container containing a second fluid, and a microfluidic mixer. A control unit is configured to control the pressure level of the first fluid and the pressure level of the second fluid. The control unit is also configured to control an opening and closing of the first valve and of the second valve to inject the first fluid and second fluid successively into the microfluidic mixer, thereby generating a profile of fringes of the first fluid and of the second fluid within the common outlet channel.

Described herein are novel construction materials and construction material compositions, processes, and equipment for manufacturing press-formed biocement and bioconcrete products and construction materials. In some embodiments, the methods include combining aggregate particles with a first measured dose of at least one biological organism or enzyme and a first measured dose of cementation reagents in a first mixer, mixing the contents of the first mixer and reacting the first measured dose of the cementation reagents in the presence of the first measured dose of the at least one biological organism or enzyme to form a biocement which binds to the surfaces of the aggregate particles, thereby increasing the size of the particles to yield a biocement coated aggregate.

An acoustic rotary liquid processor coupled with high-intensity ultrasonic vibration, rotary stirring, gas purging, and melt surface stabilizing is described. The processor can be used for the synthesis of particulate reinforced composite materials, scavenging dissolved gases in molten materials, and preparation of a slurry containing a small fraction of non-dendritic solid particles for semi-solid material processing.

A process for preparing a hop extract emulsion, at least comprising the steps of: Providing a hop extract, mixing the hop extract with water, wherein the mass ratio of water to hop extract is from 40:60 to 95:5 (water:hop extract), and homogenizing the resulting mixture using ultrasound, resulting in the hop extract emulsion; and the hop extract emulsion prepared according to the invention, beverages and foodstuffs prepared thereby, and corresponding uses.

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.
