Biological material fouling assessment systems and methods are described. According to one aspect, a biological material fouling assessment system includes processing circuitry configured to access image data of an image of a surface of a substrate which has been fouled with biological material, wherein the image data comprises intensity information regarding a plurality of pixels of the image, and wherein the processing circuitry is further configured to process the intensity information regarding the pixels of the image to generate information which is indicative of an amount of the fouling of the biological material upon the surface of the substrate. 1. A biological material fouling assessment system comprising:processing circuitry configured to access image data of an image of a surface of a substrate which has been fouled with biological material, wherein the image data comprises intensity information regarding a plurality of pixels of the image, and wherein the processing circuitry is further configured to process the intensity information regarding the pixels of the image to generate information which is indicative of an amount of the fouling of the biological material upon the surface of the substrate.2. The system of wherein the image is a color image and the processing circuitry is configured to process the intensity information including separating the pixels into respective ones of a plurality of different color channels according to the colors of the pixels claim 1 , and wherein the processing circuitry is configured to process the pixels for the different color channels separately to generate the information which is indicative of the amount of the fouling comprising a value for each of the color channels which is indicative of the amount of the fouling of the biological material upon the surface of the substrate.3. The system of wherein the processing circuitry is configured to process the intensity information including using the intensity ...

Compositions and processes are disclosed for forming hydrophobic coatings and lubricant-infused surface coatings. Coatings may be applied to various substrates without prior chemical or temperature treatment of the substrates and over large and irregular surfaces. Coatings are self-healing, anti-fouling, and have enhanced lifetimes. 1. A process , comprising the step of:dispensing a paintable fluid comprising porous particles of a first material of a first selected size and particles of a second material of a second smaller size combined in a selected polymer to a substrate forming a hydrophobic coating thereon with a selected surface morphology.2. The process of claim 1 , wherein the surface morphology includes mounded features of a first selected size comprised of aggregates of the first particles overlaid with the second particles that provide the coating with a nanotextured surface.3. The process of claim 1 , wherein the paintable fluid further includes a pore-forming material therein configured to enhance the porosity within the polymer matrix of the hydrophobic coating.4. The process of claim 1 , wherein the first particles comprise mesoporous or nanoporous silica claim 1 , the second particles comprise nanoparticles or nanofibers of fumed silica claim 1 , and the polymer is a polydisiloxane polymer.5. The process of claim 1 , wherein the dispensing includes dispensing the paintable fluid with a solvent claim 1 , a gas claim 1 , or a combination thereof.6. The process of claim 1 , further including delivering a lubricant to a surface of the hydrophobic coating to form a lubricant-infused surface (LIS) coating thereon.7. The process of claim 6 , wherein the lubricant is delivered to the surface of the hydrophobic coating through a wicking material in fluid contact with a lubricant reservoir attached to the substrate.8. The process of claim 6 , wherein the lubricant is delivered to the surface of the hydrophobic coating through a capillary device in fluid ...
