Marine and freshwater mussels secrete proteinaceous adhesive materials for adherence to the substrates upon which they reside. It is well known that 3,4-dihydroxyphenylalanine (DOPA) key understanding these mussel proteins (MAPs). In order gain a better of their complex formation quick recovery rupturing, novel water soluble copolymers N-isopropylacrylamide dopamine methacrylate were synthesized in such way have 1, 2.5, 5 mole percent monomer with respect NIPAM on average. The statistical...
Carbonaceous nanocomposite hydrogels are prepared with an aid of a suspension polymerization method and used as anodes in microbial fuel cells (MFCs). (Poly N-Isopropylacrylamide) (PNIPAM) filled electrically conductive carbonaceous nanomaterials exhibit significantly higher MFC efficiencies than the unfilled hydrogel. The observed morphological images clearly show homogeneous dispersion carbon nanotubes (CNTs) graphene oxide (GO) PNIPAM matrix. complex formation CNTs GO NIPAM is evidenced...
In past decade, electrochemical energy storage gained undivided attention with the increase in electrical demand for usage of new technology such as moveable electronics. Li-ion batteries (LIB) have been most successful system their long-life cycle and efficiency, lower density, notable cost effectiveness small-scale storage. However, large-scale long duration, work still needs done to make LIB efficient on a scale well. Recently Li–air suggested potential systems that can provide solution...
Asphaltene precipitation and its subsequent deposition always remain a major concern for Oil industry. Formulation of comprehensive reliable risk management system asphaltene prone wells fields is challenging task because the influence diverse factors. In this study, decision support developed assessment in fields. Since, data present literature scarce not consistent, therefore, hypothetical their was considered to conduct study comprehensively. Three namely; Field A, B C were assumed each...
Novel covalent gels were prepared by complexation of polymer-bound catechols with NaBH4 at pH ≈ 9. These can absorb humidity, which changes the catechol-borate bonds from irreversible to reversible. Furthermore, humidity induces self-healing, proven rheological data.
Hybrid hydrogels of poly(N-isopropylacrylamide) (pNIPAM) containing carboxylate carbon nanotubes (CNTs) and/or zwitterions are synthesized by free radical polymerization. The supramolecular interactions among zwitterionic monomers and CNTs influence the mechanical properties diffusion mechanism in hybrid hydrogel systems. These response behavior were tested mechanically with respect to their swelling characteristics. pNIPAM CNT or pNIPAM, zwitterions, follow a Fickian behavior, while adding...
Abstract Swelling of shale potentially occurs when it is exposed to water-based drilling fluid. The migration hydrogen ions (H + ) in the nano-interlayered platelets rock utterly responsible for swelling behavior shale. Conventionally, any formation can be experimentally determined by linear dynamic swell meter. However, extremely important validate these experimental results; hence, this research study aims conducting a comparative performance analysis different kinetic models, namely...
This study investigates the rheological properties of dual-network hydrogels based on acrylamide and sodium alginate under large deformations. The concentration calcium ions affects nonlinear behavior, all gel samples exhibit strain hardening, shear thickening, densification. paper focuses systematic variation concentration-which serves as second network building blocks-and Ca2+-concentration-which shows how strongly they are connected. precursor solutions show a typical viscoelastic...
