Abstract: Compositions with supramolecular structures for use in anticorrosive methods include a corrosion inhibitor; a supramolecular host chemical or a supramolecular guest chemical configured to engage in host-guest chemistry with the corrosion inhibitor; and a solvent. Methods of inhibiting corrosion on a surface or reducing the amount of anticorrosive composition within a system include adding an anti-corrosively effective amount of the composition to the system.

Abstract: Surface-active compositions with supramolecular structures for industrial, household, agricultural, and oil and gas use include a surfactant, a supramolecular host chemical or a supramolecular guest chemical configured to engage in host-guest chemistry with the surfactant, and a solvent. The surface-active compositions optionally can be substantially free of yeast, or protein extracted from yeast. Methods of increasing wettability of a surface and increasing dispersibility in a fluid by using the surface-active compositions are also described.

Abstract: Compositions with supramolecular structures for use in oil and gas production and other applications include an H2S scavenger, a supramolecular host chemical or a supramolecular guest chemical configured to engage in host-guest chemistry with the scavenger, and a solvent. Methods of controlling H2S at a production site include applying an effective amount of the composition to the production stream.

Abstract: Compositions with supramolecular structures for agricultural use include a biological compound, a surfactant, a supramolecular host chemical or a supramolecular guest chemical configured to engage in host-guest chemistry with the biological compound, the surfactant, or both, and a solvent. Methods of treating a plant to improve nutrient assimilation, water uptake, yield, shelf life, or vigor include applying an agriculturally effective amount of the composition to the plant.
