Disclosed herein are methods, systems, and compositions for the liquid-phase deposition of film coatings onto the surface of battery material powders. The battery material powders are introduced into a reaction vessel within which the coating is to be performed. A solvent is added to the reaction vessel to fluidize the battery material powders, thereby yielding a slurry composed of the solvent and powders. A first reagent is then added into the reaction vessel to react with the slurry to produce battery material powders comprising an adsorbed partial layer of the first reagent. A second reagent is added into reaction vessel to react with the battery material powders comprising an adsorbed monolayer of first reagent, thereby yielding coated battery material powders comprising at least one monolayer film.

Methods of synthesizing nanoparticles of an isotope using a laser beam are described herein. The methods include generating the laser beam, directing the laser beam to the target to convert the target into a plasma state, and bombarding the target in the plasma state with the laser beam to maintain the target in the plasma state and synthesize the nanoparticles of the isotope. During bombarding the target in the plasma state with the laser beam, the laser beam is configured to have a pulse frequency and peak laser intensity that accelerates electrons in the plasma state and maintains the plasma state at a temperature high enough to provide for the synthesis of the nanoparticles of the isotope. Apparatuses for synthesizing nanoparticles of an isotope using a laser beam are also described herein.

The present application is directed towards systems and methods for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.

A wet granulator includes a material cylinder. A cylinder cover is rotatably arranged at an opening of the material cylinder, and a locking member is arranged on the cylinder cover. The locking member includes a locking housing, and the locking housing is provided with a first through groove. A locking pin slides in the first through groove, and the locking pin includes a middle rod and a contacting rod.
