Organic and inorganic deposits that accumulate near the wellbore create flow restrictions. These restrictions result in significant losses of crude oil and gas production and are a serious concern for operators. The organic deposits are mainly paraff

The electrodeposition of graphene oxide (GO) by covalently linked electroactive monomer, carbazole (Cbz) is first demonstrated herein. This is based on the electropolymerization and electrodeposition of covalently linked Cbz units when a potential is

Progressive reduction of the flow path of oil and/or gas in the near-wellbore region could cause a gradual decline in hydrocarbon production. The major parameters that influence the time-frame of this process are related to the properties of the crud

Utilizing a hyperbranched cored ring-opening polymerization of caprolactone, carbazole peripheral groups are extended to afford electropolymerizable star-like copolymers. Different arm lengths are obtained on the basis of different degrees of polymer

We report on the interesting interfacial behavior of oligoethylene glycol or OEGylated linear dendron monolayers at the air-water interface as a function of (a) carbazole dendron generation, (b) the length of the OEG units, and (c) the surface pressu
