Abstract: A coating and method of making, using, and applying the coating to protect structures from scratches and/or the undesired collection of slag and/or spatter associated with metal working processes. The coating includes a base layer and a top layer that, when applied, mitigate adhesion of weld slag to the underlying structure. The coating is also transparent such that it does not interfere with the functionality of any indicia associated with the underlying structure or device and also renders the coating suitable for use with photo-reactive or responsive sensors and/or other non-opaque structures—such as goggles, facemasks, and/or shields.

Abstract: According to various embodiments, a coating mixture is capable of being applied on a substrate. The coating mixture includes acidified graphite particles, a suspension of polytetrafluoroethylene resin in water, and silver ion doped microporous particles. When the coating mixture is applied to a surface of the substrate, the coating resists growth of microorganisms.

Abstract: A fouling and stiction-resistant coating suitable for use with marine streamers is made from a silicone undercoat layer and a powdery topcoat layer. The powdery topcoat layer is preferably a non-toxic fluoropolymer which has a low surface energy, a high modulus, and which is not continuous. There may also be a primer layer below the silicone undercoat layer. The powdery topcoat layer is preferably arranged to be penetrable by the feet of barnacles that come into contact with it, with the silicone undercoat layer arranged such that the barnacles' feet that penetrate the powdery topcoat layer bond with the silicone undercoat layer. The powdery topcoat layer is preferably further arranged to peel away from the silicone undercoat layer when force is applied to the barnacles to remove them from the coating.

Abstract: A conformal coating that resists fouling by waterborne contamination in aquatic environments, a method for fabricating the coating, and a filter having such a coating are disclosed. The coating comprises a hydrophilic polymer and a surfactant wherein the surfactant undergoes a phase change upon exposure to a saline solution. Also disclosed are in situ methods for regenerating anti-fouling filters having the fouling resistant coating.

Abstract: A yeast biofilm microbial fuel cell has anode and cathode chambers, each containing an electrolyte medium, separated by a proton conducting membrane. A baker's yeast biofilm is induced to form on the anode under electrical poising. A method of making the MFC includes adding baker's yeast and yeast nutrient fuel source to the anode solution, connecting a resistor across the anode and cathode to enable current flow through the resistor for a selected time for poising the anode and formation of the anodic yeast biofilm, replacing the anode solution with a fresh quantity of yeast-free solution, adding fuel source to the solution, and continuing to run the MFC for a selected time under resistance. The steps of replacing the anode solution, adding fuel source and running the cell under load are repeated until the baker's yeast has formed a suitable anodic biofilm.

Abstract: A biomimetic system for mitigating marine bio-fouling is disclosed which is based upon the sacrificial skin mechanism found in the pilot whale species. The anti-bio-fouling system is characterized by the continuous in-situ underwater formation of a conformal protective skin around a submerged object or structure and employs a circulatory system embedded in a diffuser layer conformably fitted and secured to the structure to controllably deliver a sacrificial skin-forming material to the structural surface. The system advantageously utilizes the unique chemical properties of the skin-forming material to alter the material's viscosity in response to contact with sea water such that the material is uniformly distributed over the structure surface by a self-diffusion process, notwithstanding structural configuration or gravitational orientation, thus forming a stabilized waterproof layer or sacrificial skin.

Abstract: Provided is a method for in-situ coating a substrate or matrix with magnetic metal nanoparticles. A metal salt, which may be organic or inorganic, is introduced into a solution of liquid polyol. In the presence of mechanical stirring and heat, a reduction process occurs wherein the magnetic metal nanoparticles precipitate out of solution and deposit or attach to one or more surfaces of the substrate. The concentration of reaction precursors, combined with the polyol, may be varied to control the size and shape of the magnetic nanoparticles.

Abstract: Provided is a magnetic graphite nanoplatelet, and a method of manufacturing nanocomposites by introducing the magnetic nanoplatelets into a composite matrix. Expanded crystalline graphite, in the form of graphite nanoplatelets, is mixed with magnetic particles to adhere the particles to the nanoplatelets. The magnetic graphite nanoplatelets are combined with a composite matrix, typically a polymer, to form a nanocomposite. In the presence of an applied magnetic field, the magnetic graphite nanoplatelets orient and align consistent with the magnetic field to yield a composite having enhance mechanical, electrical and thermal properties.
