Theoretical Side

The properties of binary colloidal systems have gained the interest of researchers because they have much richer structures than their one-component counterpart. Continuing efforts are being made on the theoretical side on binary colloidal systems, while many issues remained unsolved for the lack of solid experimental supports, especially for study in the field of two-dimensional (2D) binary colloids system. Oil–water interfaces can serve as a good stringent 2D confinement for colloidal particles and can avoid anomalous problems caused by the quasi-two-dimensional environment in previous experimental reports. In this work, we conduct experimental research of binary colloids system in an oil–water interface to revisit theoretical predication. We measure an ultra-long-range attraction and discuss the possible mechanism of this attraction by comparing the experimental result with existing model and theory. This study could contribute more understanding of the binary colloidal system in both experimental aspects and theoretical aspects.

A lotus leaf inspired Janus hybrid film was exquisitely fabricated through a self-assembly process on the water/air interface with subsequent in situ asymmetric modification at the oil/water interface. The interfacial asymmetric decoration strategy thus provides a novel pathway for achieving a 2D Janus hybrid film with asymmetric wettability and functionality.

The traditional emulsification theory is enriched by a self-assembly approach, in which hydrophilic copolymers with one block exhibiting electrostatic or hydrogen-bonding forces with the oil phase self-assemble at the oil–water interface, thereby reducing interfacial tension and forming emulsions.

The flow characteristics of deposited water displaced by flowing oil in hilly terrain tube were studied experimentally and numerically. Lab-scale experiments were carried out on the transparent organic glass test loop with I.D. 50 mm to investigate the distributions of oil-water interface by diesel flowing from a lower horizontal test section into the up-inclined test section. Two-dimensional numerical simulation was conducted by VOF model and CSF model based on the test geometrical model. Comparisons of the oil-water interface distribution and the critical superficial oil velocity show that the numerical simulations favorably compare with the measurements.
