摘要： Coated particles include a particulate substrate, a surface copolymer layer surrounding the particulate substrate, and a resin layer surrounding the surface copolymer layer. The surface copolymer layer includes a copolymer of at least two monomers chosen from styrene, methyl methacrylate, ethylene, propylene, butylene, imides, urethanes, sulfones, carbonates, and acrylamides. The resin layer includes a cured resin. Methods of preparing the coated particles include preparing a first mixture including at least one polymerizable material, an initiator, and optionally a solvent; contacting the first mixture to a particulate substrate to form a polymerization mixture; heating the polymerization mixture to cure the polymerizable material and form a polymer-coated particulate; preparing a second mixture including the polymer-coated substrate, an uncured resin, and a solvent; and adding a curing agent to the second mixture to cure the uncured resin and form the coated particle.

摘要： The present disclosure relates to a modified drag based wind turbine apparatus, a method of making the wind turbine and a method of using the wind turbine apparatus. The apparatus is based on a modified drag based concept whereby during a complete turn of the rotor, there will be an augmentation of a positive torque and a decrease of a negative torque resulting in double effect enhancement. The disclosed wind turbine can capture more wind kinetic energy than that energy captured by the traditional drag based wind turbines. The wind turbine apparatus comprises of a turbine supporting frame, a turbine rotor, a sail supporting arm, a sail rotational axis along with sail swinging rods, and extendable and/or shrinkable turbine sails. A simple design and construction is made for cost-effectiveness, and has small as well as large scale scalability.

摘要： A vehicular power system, a vehicle and a method of providing auxiliary power to a vehicle using an auxiliary power unit that uses a molten metal anode solid oxide fuel cell rather than an internal combustion engine. The auxiliary power unit includes a container with numerous fuel cells disposed within it such that when the metal anode is heated, the metal converts to a molten state that can be electrochemically cycled between oxidized and reduced states by oxygen and a fuel present in the molten metal, respectively. The auxiliary power unit further includes a furnace that selectively provides heat to the fuel cells in order to place the anode into its molten metal state. Seals may provide fluid isolation between the molten metal within the container and the ambient environment.

摘要： A method of preparing a polymer composite includes dispersing a nanosheet filler within a polymer matrix by dissolving a monomer in water to form a first solution, dispersing the nanosheet filler in an organic solvent in the presence of an emulsifying agent to form a second solution, combining the first solution and the second solution, and adding a polymerization initiator to initiate a polymerization reaction of the monomer to form a polymer composite precursor comprising the nanosheet filler dispersed in the polymer matrix. The method further includes quenching the polymerization reaction and then filtering, washing, grinding, and drying the polymer composite precursor to form the polymer composite. A method of preparing a polymer composite hydrogel for water shutoff applications and the associated method of forming a barrier to shut off or reduce unwanted production of water in a subterranean formation utilizing the polymer composite hydrogel is also provided.
