In this paper, the research and application of nanomaterials in oilfield chemical engineering was briefly described with emphasis on nano-silica enhanced oil recovery, depressure augmented injection. A study modification carried out indoors, a modified nano-depressure injection agent prepared by using coupling for surface grafting modification, followed introducing functional monomers in-situ m...

Liquefaction is one of the most important and complex topics in geotechnical earthquake engineering. In recent years, passive site stabilization method has been proposed for non-disruptive mitigation of liquefaction risk at developed sites susceptible to liquefaction using colloidal nano-silica stabilizer. In this research, 4 box models were used to investigate the ability to uniformly deliver ...

in our current study, supercritical water impregnation (scwi) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. the method allows nano-particles to place on support surfaces in extremely dispersed conditions. the silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...
