A nanoclay based solid sorbent is provided having a nanoclay with at least one surface, and at least one amine containing compound wherein the amine containing compound is attached to the surface, as well as a method of making it. A method of capturing carbon dioxide gas is disclosed includes passing a gas from an effluent process stream containing carbon dioxide through the nanoclay based solid sorbent and capturing the carbon dioxide gas on the surface and within the nanoclay based solid sorbent. The nanoclay based solid sorbent having the captured carbon dioxide gas is regenerated by undergoing one or more cycles of desorption of the captured carbon dioxide gas from the nanoclay. The regenerated nanoclay based solid sorbent may then be reused.

A method for making fluid elasticity measurements using an extensional viscometer () is disclosed, where stress is not directly measured but is inferred from an accurate measurement of the change in the rate of flow of a liquid during passage through a vertical capillary (). The flow rate changes when the liquid jet, also called the liquid filament, leaving a first capillary (), is stretched by the application of vacuum forces. Steady flow is established almost instantly by using a constant liquid head () above the capillary, and the flow rate is determined by timing the interval for liquid to drain between two marks () on the liquid reservoir surface. Extensional viscosity can be calculated as a ratio of the tensile stress and stretch rate of the liquid at different axial positions.
