    Abstract: 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.

    Abstract: 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.

    Abstract: Methods of preparing a crosslinked hydraulic fracturing fluid include combining a hydraulic fracturing fluid comprising a polyacrylamide polymer with a plurality of coated proppants. The plurality of coated proppants include a proppant particle and a resin proppant coating on the proppant particle. The resin proppant coating includes resin and a zirconium oxide crosslinker. The resin includes at least one of phenol, furan, epoxy, urethane, phenol-formaldehyde, polyester, vinyl ester, and urea aldehyde. Methods further include allowing the zirconium oxide crosslinker within the resin proppant coating to crosslink the polyacrylamide polymer within the hydraulic fracturing fluid at a pH of at least 10, thereby forming the crosslinked hydraulic fracturing fluid.

    Abstract: Coated proppants include a proppant particle, a surface copolymer layer surrounding the proppant particle, 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, where the copolymer is crosslinked by divinyl benzene. The resin layer includes a cured resin. Methods of preparing the coated proppants include preparing a first mixture including at least one polymerizable material, an initiator, and a crosslinker including divinyl benzene; contacting the first mixture to a proppant particle 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 proppant.

    Abstract: A polymer composite hydrogel includes a polymer composite, water, an organic crosslinker, and a salt. The polymer composite includes a nanosheet filler dispersed throughout a polymerized polyacrylamide. The nanosheet filler includes one or more of zirconium hydroxide, zirconium oxide, titanium oxide, graphene oxide, non-functionalized graphene, and hexagonal boron nitride. Further, a weight ratio of the nanosheet filler to the polymerized polyacrylamide is between 1:99 and 1:9. The polymer composite hydrogel includes 0.5 to 6 weight percent of the polymer composite and 0.25 to 5 weight percent of the salt, the salt being a monovalent salt, a divalent salt, or a combination of monovalent and divalent salts. A method of preparing a polymer composite, a method of preparing a polymer composite hydrogel for water shutoff applications, and the associated method of forming a harrier to shut off or reduce unwanted production of water in a subterranean formation is also provided.

    Abstract: 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.
