  • Methods for producing metal oxide films
    Patent number: 11814730
    Abstract: Described herein is a technology for the creation of “smooth” metal oxide films or coatings using organic cross-linking agents to enable low-temperature sintering. These metal oxide films can be used in conjunction with low-melting temperature substrates, such as plastics, metal, metal oxide, and glass, providing exquisite control over surface roughness.

  • Crystallization suppressant combinations for high density clear brine fluids
    Patent number: 11525080
    Abstract: Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines. Crystallization suppressant blends are also identified that allow for the preparation of high density clear brine fluids with lower viscosities.
