A new and tri-responsive fluorescent Schiff base probe (DBAB) has been designed developed for the recognition of iron(<sc>iii</sc>) ions (Fe<sup>3+</sup>), iron(<sc>ii</sc>) (Fe<sup>2+</sup>) copper(<sc>ii</sc>) (Cu<sup>2+</sup>) simultaneously.
Responsive wormlike micelles are very useful in a number of applications, whereas it is still challenging to create dramatic viscosity changes micellar systems. Here we developed pH-responsive system based on noncovalent constructed surfactant, which formed by the complexation N-erucamidopropyl-N,N-dimethylamine (UC22AMPM) and citric acid at molar ratio 3 : 1 (EACA). The phase behavior, aggregate microstructure viscoelasticity EACA solutions were investigated macroscopic appearance...
In recent years, multifunctional nanoparticles have attracted much research interest in various biomedical applications such as biosensors, diagnosis, and drug delivery systems.
This work reports a mechanistic study of template-directed synthesis silica nanomaterials utilizing self-assembled peptide nanotubes as scaffolds. An ultrashort amphiphilic (I3K) underwent self-assembly in aqueous solution under ambient conditions to form long and uniform nanotubes. The assembled then were used templates for the subsequent fabrication from tetraethoxysilane (TEOS), also conditions. In order gain better insight into mediation on formation nanostructures, we have carefully...
Reservoir pressure is a key factor affecting the degree of spontaneous imbibition. In this work, oil distribution characteristics in core samples were simulated before and after imbibition using nuclear magnetic resonance (NMR) technology. Specifically, four selected subjected to experiments at 0.1, 5, 10, 15 MPa, respectively. Furthermore, efficiency rate different pressures can be quantitatively calculated NMR T2 spectrum. The results indicate that smaller larger pores has no obvious trend...
ABSTRACT An amphiphilic polymer with twin‐tailed hydrophobic groups was prepared by micellar polymerization of acrylamide as hydrophilic monomers, 2‐acryloylamino‐2‐methyl‐1‐propanesulfonic acid functional monomers and N , ‐dodecyl monomers. Using the same method, containing single‐tailed group not ordinary were prepared. The molecular structure product characterized infrared spectrum 1 H nuclear magnetism resonance spectrum. By inclusion complexation β‐cyclodextrin (β‐CD), association on...
In this study, the mechanism of migration/plugging and main performance polymer nano-microspheres (HQ) were investigated using environmental scanning electron microscopy (ESEM), swelling hydration experiments, sand-filling pipe flooding microscopic displacement experiments. Results show that ratio HQ in salt solution first increases then reaches equilibrium with increase time. The expansion rapidly at initial stage its maximum value after for 7 days. was 15. addition, higher salinity,...
We report in this work the phase behavior and microstructures a mixture of an anionic Gemini surfactant, sodium dilauramino cystine (SDLC), conventional cationic dodecyl trimethyl ammonium chloride (DTAC). Observation appearance shows that SDLC–DTAC mixed surfactant system transforms from isotropic homogeneous to aqueous two-phase (ASTP) then anisotropic with continuous addition DTAC. The corresponding aggregate are investigated by rheology, dynamic light scattering, transmission electron...
Water flooding is widely used for recovering crude oil from unconventional reservoirs due to its economic feasibility. At reservoir conditions, the injected water usually imbibed into fractured rocks, so-called spontaneous imbibition, providing a considerable driving force enhancing recovery. In this work, imbibition on rock surface investigated at high-pressure and influence tight recovery revealed pore-scale perspective. Specifically, three typical core samples are selected characterized...
Polyacrylamide microspheres have been successfully used to reduce water production in reservoirs, but it is impossible distinguish polyacrylamide from that enhance oil recovery and already present fluids. In order detect the reservoir produced fluid, fluorescent P(AM-BA-AMCO), which fluoresce under ultraviolet irradiation, were synthesized via an inverse suspension polymerization. keep particle size distribution a narrow range, synthesis conditions of polymerization studied, including...
