imparts novel mechanical and functional properties to the macroscopic interface itself. These properties include size-and charge-selective pathways for molecules and particulates, shear and compressive moduli, and selective binding and reaction sites. Complex interfaces can then be used to generate complex, macroscopic, all-liquid materials with very high surface areas that have unique properties, such as compartmentalization, communication between compartments, and the ability to move and reconfigure. With the rapid growth in the study of complex materials made from interfacially structured liquids, there is a need to review the field from the funda-Liquid-fluid interfaces provide a platform both for structuring liquids into complex shapes and assembling dimensionally confined, functional nanomaterials. Historically, attention in this area has focused on simple emulsions and foams, in which surface-active materials such as surfactants or colloids stabilize structures against coalescence and alter the mechanical properties of the interface. In recent decades, however, a growing body of work has begun to demonstrate the full potential of the assembly of nanomaterials at liquid-fluid interfaces to generate functionally advanced, biomimetic systems. Here, a broad overview is given, from fundamentals to applications, of the use of liquid-fluid interfaces to generate complex, all-liquid devices with a myriad of potential applications.

“…The mechanical properties of the printed liquids are derived from both the mechanical properties of the NPS assembly and the surface tension of the NPS‐laden oil–water interface . The surface energy of the system, while a source of controversy for nanoparticle‐laden interfaces, contains contributions from both the oil–water surface tension and the interactions between NPSs, the latter of which becomes particularly significant when the NPS assembly is jammed. Diffusion of water out of the threads results in a hoop stress that acts on the NPS assembly (Figure a).…”

Liquids lack the spatial order required for advanced functionality. Interfacial assemblies of colloids, however, can be used to shape liquids into complex, 3D objects, simultaneously forming 2D layers with novel magnetic, plasmonic, or structural properties. Fully exploiting all-liquid systems that are structured by their interfaces would create a new class of biomimetic, reconfigurable, and responsive materials. Here, printed constructs of water in oil are presented. Both form and function are given to the system by the assembly and jamming of nanoparticle surfactants, formed from the interfacial interaction of nanoparticles and amphiphilic polymers that bear complementary functional groups. These yield dissipative constructs that exhibit a compartmentalized response to chemical cues. Potential applications include biphasic reaction vessels, liquid electronics, novel media for the encapsulation of cells and active matter, and dynamic constructs that both alter, and are altered by, their external environment.

Traditional ways which used to remove the oil from water such as flotation and skimming, are helpful for the separation of leaked oil from surface of water , but afford from the limits of high operation cost and low efficiency, as well as, they are not valid to the separation of leaked oil from water emulsions [5,6].…”

A superhydrophobic aerogel has been utilized as adsorbed the Crude oil leaked during transport in the waters of the Tigris and Euphrates rivers, and determine the capacity absorbing of the aerogel powder for crude oil. This technique is very important to get rid of environmental pollution caused by the leakage of crude oil in water, which in turn cause the death of fish, this application is an important economic wealth in the country, preliminary tests on Tigris and Euphrates rivers mixed with the crude oil, by using the aerogel in powder form to clean the water from crude oil, the study depended on two parameters are surface area and contact angle. We found that the increasing on surface area lead to increasing on the capacity of adsorbing the crude oil from water, also this result with contact angle.
