An imaging device (100) is disclosed comprising an ultrasound transducer array (101, 120, 130) having a plurality of ultrasound transducer elements defining an ultrasound emitting surface of the ultrasound transducer array; and an acoustic window (220) on the ultrasound emitting surface, said acoustic window comprising: a first layer (221) of a hydrocarbon elastomer contacting the ultrasound emitting surface, said first layer further containing an antioxidant; and a second layer (223) of a further hydrocarbon elastomer on the first layer, said second layer having a greater Shore A hardness than the first layer. Also disclosed are an ultrasound imaging system (10) comprising such an imaging device, such as catheter (100), and a method (300) of forming an acoustic window (220) on an ultrasound transducer array (101, 120, 130) for such a device (100).

Methods of forming oxidation barriers are provided. An illustrative method comprises applying a clay mineral coating composition comprising a solvent and exfoliated clay mineral sheets, e.g., exfoliated vermiculite sheets, to a surface of a substrate; and removing solvent from the clay mineral coating composition as-applied to the surface, thereby forming a coating comprising the exfoliated clay mineral sheets on the surface. The oxidation barriers are also provided.

The present invention generally relates to a chemical process under flow conditions for manufacturing compounds which absorb ultraviolet (UV) radiation and protect biological materials as well as non-biological materials from damaging exposure to UV radiation. The present invention further includes formulations and compositions comprising such compounds for use in absorbing UV radiation, as well as methods for protecting biological materials as well as non-biological materials from damaging exposure to UV radiation.

The present disclosure provides a method for forming a barrier coating on a surface of a substrate. The method includes applying a barrier coating forming solution to the substrate, allowing the applied barrier coating forming solution to partially cure, applying an antimicrobial coating forming solution atop the partially cured barrier coating forming solution, and allowing the two applied coatings to fully cure or dry to produce a multifunctional surface coating. The barrier coating forming solution includes at least one performance component other an antimicrobial component, and the antimicrobial coating forming solution includes an antimicrobial component. A formed multifunctional surface coating produced according to the method positions the antimicrobial component at a concentrated amount at or near the surface of the formed multifunctional coating.
