    Abstract: A method for controlling a prilling bucket in the prilling of a a urea melt (UM) including: feeding the urea melt to a prilling bucket (1) which vibrates under the action of a magnetostrictive device (2), wherein the vibration of the bucket is controlled, as a function of the amount of urea melt to be prilled, by the following steps: acquisition of a time-varying input signal (3) which represents the flow rate of urea melt fed to the prilling bucket; generation of a first signal (5) and of a second signal (6), independently from each other, as a function of said input signal (3); generation of a third signal (10) having a frequency which is modulated by said first signal and an magnitude which is modulated by said second signal, and use of said third signal to drive said magnetostrictive device (2).

    Abstract: A process for producing nanoparticles of a substance, including in a first chamber, forming a dispersion of a substance in a fluid and bringing the fluid into a supercritical state; passing the dispersion from the first chamber through a cooling device or into a cooling zone in a second chamber, wherein the cooling device or cooling zone configured to reduce temperature of the dispersion below a temperature at which the fluid forms solid particles such that nanoparticles of the substance are formed, wherein the second chamber comprises a surface configured to receive the solid particles of the fluid and the nanoparticles of the substance; allowing pressure to decrease and/or temperature to increase in the second chamber to transform the solid particles into a gaseous state, removing the fluid in the gaseous state and with the nanoparticles remaining on the surface; and collecting the nanoparticles from the surface.

    Abstract: Apparatus for producing fine particles having a particle formation mechanism and a particle-outlet micro-channel may include a unit-structure including first and second portions adjacent to each other; and a first inlet defined in the first portion at a first height. A continuous phase solution is injected into the first inlet; and a second inlet is defined in the first portion at a second height different from the second height. A dispersed phase solution is injected into the second inlet. A merging volume is defined in the second portion and is defined at third height equal to either the first height and the second height, or has a value therebetween. The continuous phase solution and the dispersed phase solution are merged in the merging volume, wherein fine particles are formed. A first micro-channel and a second micro-channel branching from the merging volume communicates with the first inlet and the second inlet, respectively.
