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.

Provided is a method of producing graphene from a microwave-expandable un-exfoliated graphite or graphitic carbon, comprising: (a) feeding a powder of the microwave-expandable material onto a non-metallic solid substrate, wherein the powder is in a ribbon shape having a first ribbon width and a first ribbon thickness; (b) moving the ribbon-shape powder into a microwave applicator chamber containing a microwave power zone having a microwave application width (no less than the first ribbon width) and a microwave penetration depth (no less than the first ribbon thickness) so that the entire ribbon-shape powder receives and absorbs microwave power with a sufficient power level for a sufficient length of time to exfoliate and separate the powder for producing graphene sheets; and (c) moving the graphene sheets out of the microwave chamber, cooling the graphene sheets, and collecting the graphene sheets in a collector container or for a subsequent use.

Exemplary systems and methods associated with activating fluids using indirect plasma. In particular, liquid can be activated to high concentrations and at high volumes by thinning and mixing the liquid as it is exposed to the plasma, resulting more efficient activation. Further increases in activation can be reached by re-circulating fluid for additional exposure to the plasma. High flow rates can be achieved with integrated systems that utilize multiple activation systems with coordinated control.

Provided is a method for producing a silica aerogel blanket and an apparatus for producing the same, which are capable of easily controlling the physical properties of a silica aerogel blanket by separately injecting silica sol and a gelation catalyst to control gelation time, improving aerogel pore structure to be uniform and improving thermal insulation performance by sufficiently and uniformly impregnating the silica sol and the gelation catalyst into a blanket, reducing the loss of silica sol and gelation catalyst by allowing the silica sol and the gelation catalyst to pass on an ascending slope before gelation to remove any excessive silica sol and gelation catalyst exceeding an appropriate impregnation amount, and providing a silica aerogel blanket having less process trouble, and less dust.
