摘要： The present disclosure relates to a process to produce aqueous dispersions of graphene stabilized by cellulose, offering an alternative to the current methods of dispersion of graphene. The present process provides the advantages that it uses biodegradable cellulose compatible with the environment and can be used in industrial processes in alkaline medium or in the absence of alkali; and when graphene is stabilized with cellulose in alkaline medium it becomes unstable when in contact with natural waters, thus precipitating and being easily removed or concentrated. In other embodiments, solids obtained by drying of the dispersions, once dried, can be redispersed in aqueous alkaline solution.

摘要： A method for preparing a dispersion of nanoparticles of a solid organic dye or pigment in a liquid carrier, and dispersions formed by such a method. The method includes continuously mixing: at least one solution or slurry containing a reactant precursor for the solid organic dye or pigment in an organic or other solvent with the liquid carrier in a counter current mixing reactor to obtain reaction of the reactant precursor and formation of the solid organic dye or pigment as a dispersion of nanoparticles in the liquid carrier and solvent mixture; optionally, removing unreacted reactant precursor and/or by-product from the dispersion when present; and optionally, concentrating the dispersion.

摘要： A stirring device includes the following. A rotating holder is capable of performing a rotating operation in a state where the rotating holder holds a cartridge that accommodates a liquid agent in which a solute is precipitated in a solvent by the liquid agent being left still. A drive motor causes the rotating holder to perform the rotating operation. A posture controller corrects a stop position of the rotating holder to position the cartridge in a first posture in a case where an operation of the drive motor is stopped in a state where the cartridge is in a second posture that is different from the first posture. The first posture is a state in which the cartridge is in a normal stop posture.
