Study on Sealing Performance and Solubility of High Plastic-Soluble Aluminum-Based Sealing Ring Materials for Soluble Bridge Plugs
1070 aluminum has good plasticity, but its anisotropy and low dissolution rate limit its application as a soluble sealing ring. To solve the existing plastic anisotropy problem of 1070 aluminum-rolled plate, t...

Performance and mechanism study of PESA-IA as a green oilfield scale inhibitor: experimental and molecular dynamics simulation
Modified polyepoxysuccinic acid (PESA-IA) was prepared by grafting itaconic acid (IA) on polyepoxysuccinic acid (PESA), which was applied to inhibit the formation of calcium carbonate (CaCO3) scale in oilfield en...

Surface Modification of α-Fe2O3 Nanorod Array Photoanodes for Improved Light-Induced Water Splitting
α-Fe2O3 nanorod arrays were fabricated by a low-temperature aqueous chemical growth (ACG) technique and followed by an annealing process. For the surface do** of α-Fe2O3 nanorods, β-FeOOH nanorods obtained via ...
