Polymer corrosion inhibitors are reported to form dense films on carbon steel surfaces, and their thermostability enables survival in harsh downhole environments. In this paper, PEG-OTs was synthesized by mechanochemistry using ball mill grafting tosyl PEG. Using solvent-free green chemistry, non-toxic PEG with various molecular weights (600, 2000, 10,000 g/mol) were prepared used as inhibitors. The inhibition performance of 5 × 10−3 mol/L Q235 0.5 M HCl solution investigated static...
Copper phthalocyanine (CuPc) is a widely used organic blue pigment with color brilliance, light fastness, and low cost. However, its poor dispersibility in aqueous solutions limits the water-borne application. Lignin's hyperbranched polymer structure makes it potential dispersant. In this study, lignin functionalized carboxylic acid (−COOH) amine (−NH2) to enhance interaction solutions. Their applications as dispersants for CuPc are investigated together commercially available alkali lignin,...
P2-type layered oxide materials have attracted considerable interest because of their high safety and low cost. However, suffer from complicated Na+/vacancy ordering undesirable phase transitions, resulting in staircase-like electrochemical curves accompanied by fast capacity fading poor rate performance. A cathode material with high-entropy cation configurations, Na0.85Li0.08Mg0.04Ni0.22Al(B)0.04Mn0.62O2 (HEO), is designed successfully synthesized this work. The presence various metal ions...
Abstract The carbon capture, utilization, and storage (CCUS) process plays a crucial role in reducing dioxide (CO2) emissions. Additionally, CCUS-enhanced oil gas recovery (CO2-EOR) is widely used. During CCUS process, CO2 exists the downhole tubing as supercritical (SC) fluid under high pressure. Severe corrosion occurs presence of water environments. Corrosion inhibitors are among most economical cost-effective methods for controlling corrosion. However, conventional ineffective to control...
Many functional materials have been used in oil and gas industries. Special were needed for to withstand the high temperature pressure harsh environment of reservoir. Nanotechnologies potential introduce revolutionary changes areas This paper gives an overview nanotechnology application enhanced recovery, fracturing fluids, flow assurance, drilling, completion specialty composite industry last few years. Applications nano-materials, form solid composites nanoparticle-fluid these are...
An amperometric sensor for phenol was fabricated based on electrochemical polymerization of zincon onto a carbon paste electrode surface.
Self-assemblies dominated by coordination interaction are hardly responsive to thermal stimuli. We show that in case the coordinating mode changes with temperature, resultant assemblies also exhibit temperature dependence. The self-assemblies constructed perylene tetracarboxylate and metal ions. Compounds containing a skeleton often self-assemble into micro-belts, which is true for combination of However, unique pinecone structure was observed upon increasing system. structural transition...
Summary This paper details the study of a new fracturing fluid that is based on supramolecular complex between associative polymer and viscoelastic surfactant (VES). The crosslinked gel was weak physical attractive forces, such as van der Waals, hydrogen bonding, electrostatic interaction wormlike micelles VES. concentration in 10 times less than VES fluid. combination synergistically enhances viscosity to several more individual components alone. system optimized by experimental design....
The chemical modification of lignin has been hindered by its poor solubility; therefore, expensive polar solvents are required. Herein, this article reports a solvent-free CuAAc reaction on through ball-milled mechanochemistry, which avoids solvent use. In way, not only is the cost reduced but also goes green side. detail, hydroxyl groups first modified to alkyne end groups. Then, lignin-alkyne and ethyl azidoacetate with catalyst Cu(OAc)2 in condition at 600 rpm. This reached full...

Abstract The viscoelastic surfactant (VES) fluids have been used in stimulation of low permeability oil and gas reservoir due to their formation damage. physical association entanglement wormlike like micelle gives properties, which similar properties as polymer. However, conventional were at much higher concentration than that traditional polymer guar fluids. more effective VES performed lower are unmet needs be filled. Hence, new cationic Gemini surfactants with connecting spacer studied....
Summary Corrosion inhibitors are widely used to control corrosion under the sweet and sour environments in oil gas industry. More effective environmentally friendly need be developed. This paper studies a new gemini imidazoline (GIM) inhibitor, which two hydrocarbon chains head groups linked by rigid spacer. The GIM was synthesized through reaction of oleic acid with triethylene tetramine at 2:1 molar ratio. performance on inhibition carbon dioxide (CO2) evaluated linear polarization...
