摘要： In various aspects, methods and apparatuses for liquid-liquid extraction are provided. In certain aspects, an emulsion can be formed by combining a feed stream, an extractant, and a surfactant. The feed stream comprises a plurality of distinct components including a first component to be removed therefrom. The feed stream may be selected from a group consisting of: a hydrocarbon feed stream and an azeotrope. Then, a portion of the first component is extracted from the feed stream (or emulsion) by contact with a superoleophobic and hygroscopic membrane filter that facilitates passage of the first component and extractant through the superoleophobic and hygroscopic membrane filter. A purified product is collected having the portion of the first component removed. Such methods are particularly useful for refining fuels and oils and separating azeotropes and other miscible component systems. Energy-efficient, continuous single unit operation apparatuses for conducting such separation techniques are also provided.

摘要： Durable superhydrophobic components have a superhydrophobic material disposed (e.g., disposed) thereon that exhibits an apparent advancing dynamic contact angle of ≥about 150° and a roll-off angle of about ≤15° for water after at least 100 abrasion cycles. The superhydrophobic material may comprise a low surface energy material and a polymeric material. The superhydrophobic material may be self-healing and capable of recovering its wettability after damage. In yet other aspects, a component comprises a surface that is superhydrophobic and reduces drag in turbulent flow conditions. The surface has an apparent advancing dynamic contact angle of ≥about 150° and a roll-off angle of ≤about 15° for water, and a product of dimensionless roughness (k+) and a higher-pressure contact angle hysteresis of less than or equal to about 5.8. Methods of making such materials are also provided.

摘要： A rational design and fabrication of ZnO/Al2O3 core-shell nanowire architectures with tunable geometries (length, spacing, branching) and surface chemistry is provided. The fabricated nanowires significantly delay or even prevent marine biofouling. In some embodiments, hydrophilic nanowires can reduce the fouling coverage by up to approximately 60% after 20 days compared to planar control surfaces. The mechanism of the fouling reduction is mainly due to two geometric effects: reduced effective settlement area and mechanical cell penetration. Further, superhydrophobic nanowires can completely prevent marine algal fouling for up to 22 days. Additionally, the developed nanowire surfaces are transparent across the visible spectrum, making them applicable to windows and oceanographic sensors.

摘要： Methods for forming multiphasic microparticles by using wettability engendered template self-assembly (WETS) techniques are provided. A template is used that defines wettable regions to polar and non-polar liquids and non-wettable regions to polar and non-polar liquids. A first liquid is applied to the template and forms a solid or semi-solid release layer. A second liquid is applied over the release layer to form a solid or semi-solid first layer and a third liquid is applied over the first layer to form a solid or semi-solid second layer. The first layer and the second layer can be released from the template by removing the release layer from the template with a treatment agent to form multiphasic microparticles. Methods for making the templates and multiphasic micro particles are also provided.

摘要： Durable icephobic materials form anti-ice coatings on a variety of substrates, including for aircraft, powerlines, vehicles, marine structures, communications towers, outdoor equipment, and the like. The icephobic may comprise an elastomeric polymer with a low crosslink density (e.g., ≤1,300 mol/m3) and low initial ice adhesion strength (e.g., τice≤100 kPa prior to exposure to icing conditions). Further, the icephobic material maintains τice after 10 icing/deicing cycles that is ≥50% of the initial τice Introducing optional miscible liquids enhances interfacial slippage of chains in the elastomeric polymer. The low τice levels minimize ice buildup and eliminate necessary work to remove any accumulated ice via passive removal during normal operation. Other icephobic materials include linear polymers with plasticizers distributed therein or PDMS-silane coatings, both of which are free of any layers of surface liquids. Methods of making such icephobic materials are also provided.
