Abstract: A composition for a microtexture hydrophobic or superhydrophobic coating. The microtexture coating includes a coating layer disposed on a substrate with hydrophobic or superhydrophobic particles dispersed on top of or partially embedded in the coating layer to form an outer layer. The outer layer exhibits water repellant properties. Use of the microtexture coating permits large scale, durable hydrophobic or superhydrophobic coating applications. A method of applying a coating to a substrate creating a hydrophobic or superhydrophobic surface that includes applying a polymer material or an adhesive material to the substrate creating a polymer coating layer having a top surface; initially curing the applied coating layer for a specified amount of time allowing the coating layer to partially cure; and applying a solution, at a specified velocity, containing hydrophobic particles or superhydrophobic particles on top of the partially cured coating layer.

Abstract: Disclosed are methods for minimizing x-ray scattering artifacts, the method comprising: contacting an object with an x-ray scattering mitigation material. The contacting can comprise coating the x-ray scattering material on the object, including spraying a solution of suspension of an x-ray scattering mitigation material onto the object or dry powder coating the object with a x-ray scattering mitigation material. Alternatively, the contacting can comprise immersing the object in a fluid comprising the x-ray scattering material. The fluid can be a gas, a liquid, or a gel. The disclosed x-ray scattering mitigation material can be optimized for mitigating Compton radiation scattering or for mitigating Rayleigh radiation scattering. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
