20110081207 | SYSTEM FOR MITIGATING MARINE BIO-FOULING OF AN UNDERWATER STRUCTURE - 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. The sacrificial skin controllably self-dissolves and is shed in response to continuous contact with sea water, thereby carrying away the marine bio-fouling material. | 04-07-2011 |
20110097605 | YEAST BIOFILM BASED FUEL CELL - 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. | 04-28-2011 |
20130334130 | NOVEL FOULING RESISTANT COATING FOR FILTRATION MEMBRANES AND METHODS OF PRODUCING AND USING SAME - 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. | 12-19-2013 |
20140065370 | FOULING AND STICTION RESISTANT COATING - 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. | 03-06-2014 |
20140127486 | TRANSPARENT NON-STICK COATING COMPOSITION, METHOD AND APPARATUS - 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. | 05-08-2014 |
20150344705 | METHOD FOR BIOFOULING MITIGATION USING A SURFACE COATING WITH MAGNETICALLY ALIGNED PARTICLES - A method for biofouling mitigation using a surface coating with magnetically aligned particles. A coating material that requires curing is provided, to which magnetic particles are added; this coating is applied to a surface. The applied coating is then subjected to a magnetic field in situ such that the magnetic particles are formed into microstructures that render the surface rougher than it would be without the microstructures. The coating is then allowed to cure. The random and non-toxic surface features created by the magnetic particles and magnetic field provide the coated surface with broad spectrum fouling resistance against organisms such as barnacles and bacteria. | 12-03-2015 |
20160064470 | MICRO-FABRICATED INTEGRATED COIL AND MAGNETIC CIRCUIT AND METHOD OF MANUFACTURING THEREOF - A micro-fabricated electromagnetic device is provided for on-circuit integration. The electromagnetic device includes a core. The core has a plurality of electrically insulating layers positioned alternatingly between a plurality of magnetic layers to collectively form a continuous laminate having alternating magnetic and electrically insulating layers. The electromagnetic device includes a coil embedded in openings of the semiconductor substrate. An insulating material is positioned in the cavity and between the coil and an inner surface of the core. A method of manufacturing the electromagnetic device includes providing a semiconductor substrate having openings formed therein. Windings of a coil are electroplated and embedded in the openings. The insulating material is coated on or around an exposed surface of the coil. Alternating magnetic layers and electrically insulating layers may be micro-fabricated and electroplated as a single and substantially continuous segment on or around the insulating material. | 03-03-2016 |
