Abstract
Methods are disclosed to create and employ the use of non-vapor, non-condensable gas bubbles inside a process chamber. These non-vapor gas bubbles may be rapidly expanded and compressed in pressure-controlled cycles and can assist in the transport of fluids, particles, and by-products to and from surfaces. The gas bubbles can be generated from dissolved gas to the liquid medium, by mixing two liquids that can react with each other to generate gaseous by-products, or by using a liquid medium that can react with the surface of the object to generate gaseous by-products. The gaseous generation can be used with cyclic nucleation transport (CNX) process, such as vacuum CNX, hyperbaric CNX, or dynamic CNX.

A method comprising
- providing an object in a chamber, wherein the chamber is isolated from outside ambient;
- flowing a liquid to the chamber to at least partially submerge the object;
- dissolving a gas to the liquid;
- reducing pressure of a gaseous portion in the chamber;
- repeating dissolving gas and reducing pressure.
A method comprising
- providing an object in a chamber, wherein the chamber is isolated from outside ambient;
- flowing a first liquid to the chamber to at least partially submerge the object;
- flowing a second liquid to the chamber,
- wherein the first liquid and the second liquid are operable to react with each other to generate a gaseous by-product;
- increasing pressure of a gaseous portion in the chamber;
- reducing pressure of the gaseous portion in the chamber;
- repeating increasing and reducing pressure.
