Recently I am researching about SULFONATED COPOLYMERS; SIZE; TEMPERATURES; STABILITY; BRINE, Saw an article supported by the Advanced Energy Consortium [BEG08-013]; NSF, Div. of Chem., Bioeng., Env., Transp. Sys. [1833214]; Center for Bio-Inspired Energy Science – U.S. Department of Energy (DOE), Office of Science, Basic Energy Sciences (BES)United States Department of Energy (DOE) [DE-SC0000989]; National Science Foundation under NSFNational Science Foundation (NSF) [1541959]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Yu, J; Nap, RJ; Szleifer, I; Wong, JY. The CAS is 103-50-4. Through research, I have a further understanding and discovery of Benzyl ether. Recommanded Product: 103-50-4
Superparamagnetic nanoparticles (SPIONs) can be used as nuclear magnetic resonance (NMR) signal enhancement agents for petroleum exploration. This enhancement effect is uniform if SPIONs are monodisperse in size and in composition; yet it is challenging to synthesize mono disperse particles that do not aggregate in high salinity petroleum brine. Here, we report a method to synthesize individual SPIONs coated with tunable surface coating densities of poly(2-acrylamido-2-methyl-1-propanesulfonic acid (pAMPS) with a catechol end-group (pAMPS*). To establish parameters under which pAMPS*-coated SPIONS do not aggregate, we compared computational predictions with experimental results for variations in pAMPS* chain length and surface coverage. Using this combined theoretical and experimental approach, we show that singly dispersed SPIONs remained stabilized in petroleum brine for up to 75 h with high surface density pAMPS*.
