“…Meanwhile, by combining cellulose nanocrystals or oxidized cellulose nanofibers (TOCNs) with the PVA and PAM gels, the toughness of the gel can be improved. , Researchers have explored the role of crosslinkers in improving the temperature and salt resistance of the PVA gels that have applications in water shut-off. Hoskin and Shu . developed a crosslinker for PVA that was a mixture of phenolic derivatives and an aldehyde that enhanced the thermal stability of PVA.…”

Polymer gels can be effectively applied to plug fractured reservoirs and carbonate cave strata. Herein, polyvinyl alcohol (PVA), acrylamide, and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) were used as raw materials to prepare interpenetrating three-dimensional network polymer gels using formation saltwater in the Tahe oilfield (Tarim Basin, NW China) as a solvent. The effect of AMPS concentration on the gelation properties of PVA in high-temperature formation saltwater was analyzed. Further, the effect of PVA concentration on the strength and viscoelastic properties of polymer gel was studied. The polymer gel could retain stable continuous entanglement at 130 °C and exhibited satisfactory thermal stability. Continuous step oscillation frequency tests showed that it exhibited an excellent self-healing performance. Scanning electron microscopy images of the simulated core by gel plugging showed that the polymer gel could firmly fill the porous media, indicating that the polymer gel exhibits excellent application prospects in oil and gas reservoirs under high-temperature and high-salinity conditions.

In 1831, with the publication of her translation of Laplace's Mécanique Céleste, Mary Somerville (1780-1872) solidified her reputation throughout Western Europe as a highly proficient mathematician, and an expert in 'French analysis'. To shed light on her preliminary studies, we here examine Somerville's earliest known mathematical work, namely her published and unpublished solutions to questions posed in the New Series of the Mathematical Repository, alongside her contemporary correspondence with mathematicians John and William Wallace. These submissions demonstrate her active engagement in the circulation of the differential calculus twenty years earlier than previously appreciated.
