Abstract: A method for producing fluorinated boron nitride involves heating a reactor chamber, providing boron nitride in the reactor chamber, flowing fluorine and an inert gas through the reactor chamber, and exposing the boron nitride to the flowing gases and the heat. The method may include boron nitride that is exfoliated or non-exfoliated. The fluorinated boron nitride that is produced from this method may have a hexagonal crystal structure or a cubic crystal structure. The method may additionally comprise removing the fluorinated boron nitride from the reactor chamber and mixing it with a surfactant. A suspension may comprise particles of fluorinated boron nitride suspended in a fluid, which may be polar or non-polar, and may additionally include a surfactant. The fluorinated boron nitride may have a hexagonal or a cubic crystal structure. Furthermore, the boron nitride may be exfoliated or non-exfoliated.

Abstract: A process for making a layered multi-material structural element having controlled mechanical failure characteristics. The process includes the steps of: supplying a cementitious layer and forming a polymer layer on the cementitious layer by additive manufacture such that the polymer layer has a first thickness and the cementitious layer has a second thickness, wherein the polymer layer comprises a polymer and the cementitious layer comprises a cementitious material; and allowing the polymer from the polymer layer to suffuse into the cementitious layer for a period of time to obtain a suffused zone in the cementitious layer such that the suffused zone has a third thickness that is less than half the second thickness.
