Disclosed is a method for preparing a perovskite nanoparticle using a fluidic channel including a first step of forming a fluidic channel including a first outer tube, a second outer tube, and a storage tube capable of introducing flows of fluids, a second step of inducing formation of the perovskite nanoparticles by continuously preparing a mixed fluid with a laminar flow based on a flow rate by introducing a flow of a base fluid into the first outer tube, and introducing a flow of a dispersion fluid in the same direction as the flow of the base fluid into the second outer tube, and a third step of separating the perovskite nanoparticles from the mixed fluid stored in the storage tube.

A mixing and dispensing device and method. In particular, the device used by the applied method reduces the risk of chlorine gas formation while providing a stable, effective and safe disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device includes a highly concentrated disinfectant and dilutes the concentrate through the device while simultaneously mixing the concentrate with a dilute solution of an organic acid. The two diluted solutions are mixed without production of chlorine gas and to a level of safety before being dispensed to produce the stable, effective and safe neutral pH sodium hypochlorite solution disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device can be in the form of a kit for retrofitting into institutions or isolated, remote areas in need thereof or for off the shelf use in the home.

The present disclosure provides an apparatus for producing fine particles, the apparatus comprising: a particle formation mechanism and a particle-outlet micro-channel. The particle formation mechanism may include a unit-structure, wherein the unit-structure includes: first and second portions adjacent to each other; a first inlet defined in the first portion at a first height, wherein a continuous phase solution is injected into the first inlet; a second inlet defined in the first portion at a second height different from the second height, wherein a dispersed phase solution is injected into the second inlet; a merging volume defined in the second portion adjacent to the first portion, wherein the merging volume is defined at third height, wherein the third height is equal to either the first height and the second height, or has a value between the first height and the second height, wherein the continuous phase solution and the dispersed phase solution are merged in the merging volume, wherein fine particles are formed via the merging between the continuous phase solution and the dispersed phase solution in the merging volume; and a first micro-channel and a second micro-channel branching from the merging volume so as to be in communication with the first inlet and the second inlet, respectively.

The method of present disclosure relates to a writing apparatus for dispensing writing fluid on a writing surface. The writing apparatus comprises a sensor, containers for storing one or more mixing elements, a processor and a memory communicatively coupled to the processor. The writing apparatus compares the characteristics with predefined characteristics to determine quality of the writing surface. Further, the writing apparatus also determines a quality of the writing fluid suited for the writing surface. Based on the quality of the writing surface and the writing fluid, the writing apparatus modifies at least one property of the writing fluid before dispensing the writing fluid on the writing surface. For modifying the property, the one or more mixing elements are added into the writing fluid. Once the writing fluid is modified, the writing apparatus dispense the writing fluid on the writing surface.

The present invention relates to the phantom comprises water, an oil, an emulsifier and an oil coagulating agent.

Disclosed herein are inversion systems and methods of diluting w/o lattices including about 10 wt % to 80 wt % of a water soluble polymer. Using the inversion systems and methods described herein, dilution of w/o lattices is carried out in a single step to form dilute lattices having 10,000 ppm or less polymer; the dilute lattices form polymer solutions with no further addition of mixing force or water. The solution viscosities of the polymer solutions obtained using the systems and methods of the invention are at least about 80% of solution viscosity expected in the absence of shear.

The instant invention relates to a solid product comprising a liquid biologically active agent which is intimately associated to a stabilizing agent; particularly a solid product that can be reconstituted to a clear, stable, stabilized nanodispersion or loaded micelles comprising a polymer as a stabilizing agent and a liquid, preferably water immiscible, biologically active agent. The instant invention is further directed toward a process for the production of the above solid product; particularly to micelles or nanodispersions produced by hydration of a cake or powder of the solid product, produced via an effective treatment of a stabilized solution comprising for example a polymer as a stabilizing agent, such as an amphiphilic block copolymer or a small molecular weight surfactant, loaded with a liquid biologically active agent, such as propofol, an optional additive, and a suitable solvent.

A method for operating a steam power plant having a water-steam circuit, according to which method the process wastewater produced is collected from the water-steam circuit, in a separated manner according to the degree of contamination thereof, in a number of partial wastewater quantities is provided. At least a first partial wastewater quantity having a first degree of contamination and at least a second partial wastewater quantity having a second degree of contamination are formed in the process. The second degree of contamination is higher than the first degree of contamination. The first partial wastewater quantity and the second partial wastewater quantity are mixed together in such a manner that a combined process wastewater is produced, which is fed to a wastewater treatment plant.
