A method of fabricating an coating includes providing a coating comprising a base material. The base material is coated with an inorganic material using at least one of an atomic layer deposition (ALD), a molecular layer deposition (MLD), or sequential infiltration synthesis (SIS) process. The SIS process includes at least one cycle of exposing the coating to a first metal precursor for a first predetermined time and a first partial pressure. The first metal precursor infiltrates at least a portion of the base material and binds with the base material. The coating is exposed to a second co-reactant precursor for a second predetermined time and a second partial pressure. The second co-reactant precursor reacts with the first metal precursor, thereby forming the inorganic material on the base material. The inorganic material infiltrating at least the portion of the base material. The inorganic material is functionalized with a material.

A bottom plate for a marine boom includes a main plate extending in a first plane. The main plate has first and second ends with first and second sides extending there between. The first plane is defined by a longitudinal axis extending between the first and second ends and a lateral axis normal to the longitudinal axis and extending between the first and second sides. Top and bottom surfaces are bounded by the first and second ends and the first and second sides and extend parallel to the first plane. At least one lug is attached to the main plate and extends in a second plane generally perpendicular to the first plane. The lug includes a flange defining an aperture aligned generally parallel with the lateral axis, where radial thickness of the flange increases toward the main plate and decreases away from the main plate.

A process is provided for the determination of oil dispersant effectiveness. A submersible dispersant sensing platform is passed across a body of water. The platform has a plurality of sensors including a multichannel fluorometer and a particle size analyser, and each sensor produces an output data stream. The body of water is continuously analysed at a predetermined depth profile below the surface of the body of water. Hydrodynamic and environmental condition data is collected proximate in time and location to the output data from the dispersant sensing platform. The environmental condition data includes one or more of ambient temperature, body or water temperature, salinity of the body of water, wind speed, location, mixing energy of the body of water and derivatives thereof. Oil and dispersant data is provided which includes characteristics of the dispersant and of oil samples prior to the application of the dispersant. The output data stream, the hydrodynamic and environmental condition data, and the oil and dispersant data is processed to generate an indicator of the state of dispersion of the oil and of the oil dispersant efficiency under the hydrodynamic and environmental conditions the oil is exposed to. A system for the determination of oil dispersant efficacy is also provided.

A method for absorbing liquids, such as liquid hydrocarbons, includes applying recycled carpet material to the liquid. The recycled carpet material is prepared by shredding carpet and removing fibers from the shredded carpet to obtain carpet backing material. The carpet backing material may be further treated to remove fibers. The carpet backing material is then applied to the liquid.

The group of inventions relates to the field of organic chemistry and can be used for collecting films of petroleum, oils, mazut, fuels, hydrocarbons and other petroleum products with the aim of cleaning the surface of water, and also for cleaning water flows which have been contaminated by petroleum or petroleum products. A substance for collecting petroleum or petroleum products from the surface of water includes a natural polymer and additionally includes a biodegradable surfactant in the form of an aqueous solution with a concentration of no less than 0.1 g/L, and, as the natural polymer, contains polysaccharide microgels having a mass of between 20,000 and 200,000 daltons and a particle size of between 50 and 600 nm in the form of an aqueous solution with a concentration of no less than 0.2 g/L, wherein the ratio of polysaccharide microgels to biodegradable surfactant is between 12:1 and 2:1. Methods for collecting petroleum or petroleum products from the surface of water include processing the surface of a film of petroleum or petroleum products using a reagent, and then collecting the product of the reaction thereof. The reagent consists in polysaccharide microgels having a mass of between 20,000 and 200,000 daltons and a particle size of between 50 and 600 nm. According to a first variant, before or after spraying the reagent, a biodegradable surfactant is used for processing a film of petroleum or petroleum products, or a portion of said film; or, according to a second variant, the reagent is first mixed with the biodegradable surfactant until achieving a ratio of polysaccharide microgels to biodegradable surfactant of between 12:1 and 2:1. The technical result consists in decreasing the specific consumption of reagents used in the process of collecting petroleum or petroleum products from the surface of water, in enhancing the surfactant qualities of reagents, and also in reducing the residual amounts of said reagents in water.

The tip of a suction hose is supported by a floating support mechanism so that the suction port is maintained at a prescribed distance above the water surface and the base end of said suction hose is connected to the suction port of a turbofan. By the suction force of the turbofan, the oil film floating on the water surface is sucked along with the air above the water surface and the surface water through the suction hose from the suction port. The mixed fluid of air, oil and water that is delivered from the delivery port of the turbofan is sent to an oil-water separation device. The air is released into the atmosphere, and the oil and water are separated. For the turbofan, the rotational force of a separately disposed motor is transmitted by a belt transmission mechanism and rotates an impeller.
