Improving oil production for high-salinity reservoirs using polymer flooding is challenging due to chemical and mechanical degradations. This study developed two biodegradable biopolymers based on graft copolymerization of guar gum (GG) with different co-monomers, which are acrylamide (Am) 2-acrylamido-2-methylpropane sulfonic acid (AMPS), cross-linked by N,N′-methylene bisacrylamide (MBA) face these challenges. The newly synthesized gum-based hydrogels, GG-g-poly(Am-AMPS) (GH)...
Uranium is the backbone of nuclear fuel used for energy production but still a hazardous environmental contaminant; thus, its removal and recovery are important security protection. So far, development biocompatible, efficient, economical, reusable adsorbents uranium challenge. In this work, new orange peel biochar-based hydrogel composite was prepared by graft polymerization using guar gum acrylamide. The composite's structural, morphological, thermal characteristics were investigated via...
Abstract The effectiveness of modified guar gum ( Cyamopsis tetragonoloba ) as a Cd(II) and Cu(II) adsorbent in aquatic media was investigated. Synthesis based on copolymerization with 2‐Acrylamido‐2‐methyl‐1‐propane sulfonic acid acrylamide presence methylene bis‐acrylamide cross linker the form hydrogel adsorbent. Various analytical techniques were employed to describe surface morphology Adsorption tests carried out under different conditions dose (10–50 mg), initial concentration (25–150...
Approaches for designing advanced nanomaterials with hyperbranched architectures and lack of volatile organic content (VOC) have attracted considerable attention.
A non-toxic foul-release model of silicone/spherical AgNP hybrid nanocomposites with enhanced hydrophobicity, self-cleaning, and marine fouling release performance.
Heavy metal ions are discharged into water from several industries. They carcinogenic and they cause severe environmental hazards. In the present work ability of removal copper lead aqueous solutions has been studied using carboxy methyl β cyclodextrin, poly(ethylene glycol) cyclodextrin their magnetic counterparts. Effects pH, concentration ion, temperature contact time have studied. Equilibrium isotherms for adsorption metals were measured experimentally. Results analysed at different...
Environmental concerns about the use of toxic antifoulants have increased demand to develop novel, environmentally-friendly antifouling materials. Silicone coatings are currently most effective non-toxic alternatives. This study focused on developing a model for silicone foul-release nanocomposites that were successfully designed, fabricated, characterized, and tailored toward (FR) coatings. A series elastomeric polydimethyl-siloxane (PDMS)/Cu2O nanocube composites with different nanofiller...
The present work aims to develop a method for preparation of porous iron oxide nanomaterials and investigate the applicability as smart self-healing protective coatings steel.
The corrosion performance of carbon steel was tested in four polymeric ionic liquids (PILs) that differed only the fatty acid linked to chitosan (CS) amine group. measurements were implemented involved hydrogen evolution rate (HER), gravimetric measurements, potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), and quantum chemical estimations. morphology elements arranged on metal considered by a scanning electron microscopy (SEM) system attached an energy...
The data presented in this article are related to the research entitled "Smart photo-induced silicone/TiO2 nanocomposites with dominant [110] exposed surfaces for self-cleaning foul-release coatings of ship hulls" (Selimet al., 2016) [1]. This reports on successfully designing and controlling TiO2 spherical single crystal photo-nanofillers indicating evidence fouling resistance after stimulation through UV radiation exposure. These also reveal that influence well-dispersed nanoparticles...
