    Abstract: According to one or more embodiments, a plate grid distributor for distributing a fluid in a vessel or a plenum for removing a fluid from a vessel may include a plate and a skirt. The skirt may be in direct contact with the plate and may include a first portion and a second portion. The first portion may be in direct contact with the plate and the second portion may be in direct contact with the first portion. The first portion may have a first allowable stress and the second portion may have a second allowable stress. According to one or more other embodiments, a method of distributing a fluid through a plate grid distributor in a vessel may include passing the fluid into the vessel and directing the fluid through the plate grid distributor.

    Abstract: Some variations provide a system for producing a functionalized powder, comprising: an agitated pressure vessel; first particles and second particles contained within the agitated pressure vessel; a fluid contained within the agitated pressure vessel; an exhaust line for releasing the fluid from the agitated pressure vessel; and a means for recovering a functionalized powder containing the second particles disposed onto surfaces of the first particles. A preferred fluid is carbon dioxide in liquefied or supercritical form. The carbon dioxide may be initially loaded into the pressure vessel as solid carbon dioxide. The pressure vessel may be batch or continuous and is operated under reaction conditions to functionalize the first particles with the second particles, thereby producing a functionalized powder, such as nanofunctionalized metal particles in which nanoparticles act as grain refiners for a component ultimately produced from the nanofunctionalized metal particles. Methods for making the functionalized powder are also disclosed.

    Abstract: A pulsed compression reactor may include a reactor housing, a spring piston, and a driver piston. The reactor housing may define an interior volume, and may include a first passage and a second passage which lead to the interior volume. The spring piston may be positioned within the interior volume, wherein the spring piston and the reactor housing at least partially define a perimeter of a gas spring buffer chamber within the interior volume. The driver piston may be positioned within the interior volume, wherein the spring piston, the driver piston, and the reactor housing at least partially define a perimeter of a reaction chamber within the interior volume.
