Methods for making a plurality of nanoparticles are provided. The method may include flowing a first component of the core into a reaction chamber; flowing a polymeric material into the reaction chamber; and flowing a second component of the core into the reaction chamber such that the first component reacts with the second component to form a core. The polymeric material forms a polymeric shell around the core.

A submergible marine barrier protecting marine installations in a protected zone against intrusion and providing a containment barrier against spread of floating spills or bodies. The body of the barrier is supported above water by a main body thus preventing intrusion and containing floating spillage. A weight in main body keeps the barrier upright, and a rigid floatation chamber in the main body keeps it afloat when full of air. A skimming pipe collects floating pollution. Flooding the floatation chambers causes the barrier to submerge allowing access to the protected zone and protecting the barrier from storms. Body, main body, and floatation chambers are made of extruded material with flotation properties (e.g. plastic pipes). Floatation chambers are connected by air hoses and have air venting tubes at their bottom. Sensors detect approaching intruders and pollution, while spikes, barbed-wire and diver-net or any known barrier are used to stop them.

A marine debris collection device includes an outer container, an inner container provided inside the outer container so as to be movable in an upward-downward direction with respect to the outer container, a pump to move the inner container downward and cause seawater and debris to flow into the inner container via an opening, and a lower buoyant body detachably attached to a lower portion of the inner container to maintain the opening of the inner container above a water surface when the pump is not driven.

Articles are provided for absorbing fluids. In embodiments, the articles of the present disclosure are modified to make them hydrophobic, thereby decreasing their affinity for water and similar liquids, while increasing their affinity for other hydrophobic materials, including oil. After use, the articles, in embodiments sponges, may have their absorbed materials removed therefrom, and the articles may then be re-used to absorb additional materials.

A floatable modular device for absorbing oil from a surface, includes a generally disk-shaped floatable cage tapering towards the periphery of the cage in a peripheral region thereof; and a water-repellent strip- or chip-shaped oil absorbent accommodated in the cage, wherein the cage further includes at least one connector, element configured for joining plural ones of the modular devices together, to form an articulate oil absorber in which the individual cages are oriented in parallel to one another. A method of manufacturing the device includes providing a first, grid-like sheet made of plastics, positioning a water-repellent strip- or chip-shaped oil absorbent on the first grid-like sheet, positioning a second sheet on the oil absorbent, and welding the first and second sheets together at their peripheries, with the oil absorbent in between, wherein peripheral regions of the first and second sheets are bent towards one another.

A hybrid water filtering cleaning and quality monitoring device integrates multiple elements into one main system, including oil filtering, bacterial management, trash collection and water quality monitoring.

The cleaner according to the invention includes a body part, which includes curved wiping tongues. The lower part of the body is the cleaner's curved lower plate and in its upper part are upper plates and an attachment plate, which is attached to the body of the collector by an attachment beam. The construction of the collector is based on discs surrounding a drum and permitting water to flow through them, to which are attached plastic rings and, attached to them, a brush ring formed of brushes extending over the curved rear wall. The invention also discloses a cleaner, by means of which the brushes are cleaned, which, for example, are attached to a V-shaped brush structure, in which there is a plastic bodied brush ring, and in the cleaner there is a point-shaped plate and its bent point shape.
