  • A combination of functional nanoparticles and liquid streaming can be used to generate structures for the fabrication of soft functional materials. In this study, authors demonstrate the creation of Janus-structured liquids with anisotropic and programmable distributions of nanoparticles by utilizing interfacial assembly and jamming of nanoparticles at the liquid-liquid interface.

  • The effect of silica nanoparticle size and concentration on the mechanical strength and wellbore plugging performance of SPAM/ chromium (III) acetate nanocomposite gels was investigated. First, the rheological behavior of gelant, surface chemistry, morphology, and viscoelastic properties of synthesized nanocomposites were investigated. In addition, an experimental setup was designed to determine the maximum differential compressive pressure (DCP) that the synthesized nanocomposite gels can tolerate before failing. The nanocomposites containing 20–30 nm particles have a higher DCP in comparison to those having 7–10 and 60–70 nm nanoparticles.
