摘要： A composite of polyurethane foam grafted with carbon nanofibers is described. This composite foam may be made by contacting and drying a polyurethane foam with a suspension of carbon nanofibers and then drying. Additional carbon nanofiber layers may be added with repeated contacting. The composite film has a high surface area of 276 m2/g and a hydrophobic character that may be exploited for separating an oil phase from water.

摘要： Disclosed is a copper coated stainless-steel hydrophobic mesh and a method for synthesizing the hydrophobic mesh. In the method, a stainless-steel mesh is sonicated in a solution of acetone and ethanol, and then electroplated in a copper solution to form a copper coating on the surface of the mesh. The copper-coated stainless-steel mesh is treated with an oxidizing solution having an oxidizing potential applied to it. The mesh is then washed with water and dried. The copper-coated stainless-steel mesh is then immersed in a lauric acid solution. The mesh is then rinsed with ethanol to remove adsorbed lauric acid. After drying, the so-synthesized copper-coated stainless-steel hydrophobic mesh is characterized in that it has hydrophobic branches of lauric acid.

摘要： A composite material of polyurethane foam having a layer of reduced graphene oxide and polystyrene is described. This composite material may be made by contacting a polyurethane foam with a suspension of reduced graphene oxide, drying, and then irradiating in the presence of styrene vapor. The composite material has a hydrophobic surface that may be exploited for separating a nonpolar phase, such as oil, from an aqueous solution.

摘要： A graphene-modified graphite pencil electrode (GPE) system and a method for simultaneous detection of multiple anylates such as dopamine, uric acid, and L-tyrosine in a solution. The electrode system includes a graphene-modified graphite pencil working electrode comprising a graphite pencil base electrode and a layer of three dimensional nanostructured multiwall network forming concave shape structures on the surface of the graphite pencil base electrode, a counter electrode, and a reference electrode. The method comprises contacting the solution with the graphene-modified GPE system and conducting voltammetry, preferably square wave voltammetry, to detect the L-tyrosine concentration in the solution.
