What is liquid liquid interface?
Liquid-liquid interface is the junction between two immiscible liquids—a heterogeneous system created by two solvents of different solvation characteristics [1].
What is the liquid gas interface?
2.3 The Gas–Liquid Interface Is a Special Environment for Photochemistry. The gas–liquid interface presents a unique environment for (photo)chemical reactions. First, reaction at this interface provides access to reactants either within the solution phase, or in the gas phase, or both.
What is liquid solid interface?
The solid-liquid interface is that between a solid (phase α) and a liquid (phase β). The solid/liquid interfacial tension can reach low values. Polar (high surface energy surface) solids are not easily wetted by nonpolar liquids, and a surfactant is needed to disperse the polar particles in a nonpolar liquid.
What is liquid interface in physical pharmaceutics?
LIQUID INTERFACES Surface and Interfacial Tensions In the liquid state, the cohesive forces between adjacent molecules are well developed. For the molecules in the bulk of a liquid They are surrounded in all directions by other molecules for which they have an equal attraction.
What is an interface in science?
interface, surface separating two phases of matter, each of which may be solid, liquid, or gaseous. An interface is not a geometric surface but a thin layer that has properties differing from those of the bulk material on either side of the interface.
What is the difference between surface and interface?
Common Sense: A surface is the shell of a macroscopic object (the inside) in contact with its environment (the outside world). An interface is the boundary between two phases.
What is adsorption at liquid interface?
Adsorption is the adhesion of atom , ions or molecules from a gas, liquid, a dissolved solid to a surface.
What is it called when a liquid turns into a gas?
Vaporization of a sample of liquid is a phase transition from the liquid phase to the gas phase. There are two types of vaporization: evaporation and boiling. Evaporation occurs at temperatures below the boiling point, and occurs on the liquid’s surface.
Is Example of solid solid interface?
A solid–solid interface that arises from an orientation difference or a translation between two crystals of the same phase across an interface is referred to as a homophase interface. Examples of homophase interfaces include interfaces such as grain boundaries, twin boundaries and stacking faults.
What is triple point of substance?
triple point. The temperature and pressure at which a substance can exist in equilibrium in the liquid, solid, and gaseous states. The triple point of pure water is at 0.01°C (273.16K, 32.01°F) and 4.58 mm (611.2Pa) of mercury and is used to calibrate thermometers. Compare critical point.
What is surfactant in chemistry?
Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants.
WHAT IS interface in physical chemistry?
In the physical sciences, an interface is the boundary between two spatial regions occupied by different matter, or by matter in different physical states. The interface between matter and air, or matter and vacuum, is called a surface, and studied in surface science. Interfaces can be flat or curved.
What is the liquid-liquid interface strategy for Nanotechnology?
Benjaram M. Reddy, in Nanostructures for Novel Therapy, 2017 Liquid–liquid interface strategy is an excellent, simple, and straightforward method to produce nanocrystalline films of metals, metal chalcogenides, and metal oxides by the process of self-assembly at liquid–liquid interface.
What are the equilibria of a liquid/liquid interface?
In the case of a liquid/liquid interface, both charge regions are formed by ions: anions on one side and cations on the other. As a whole, in any case, the interfacial region should be electrically neutral (see Figure 17.3.1 ). Figure 17.3.1. The equilibria of the interfaces. (a) Liquid/liquid interface; (b) Electrode/electrolyte interface.
What influences the interfacial energy of the assembly process at liquid–liquid interface?
The interfacial energy of the assembly process at liquid–liquid interface is influenced by the following factors: (1) nature of the interface, (2) alteration of surface of the NPs at interface, and (3) the effective radius of the NPs, smaller NPs are weakly attached to the interface than larger particles ( Rao and Kalyanikutty, 2008 ).
What is the difference between a metallic and a liquid interface?
In the case of a metallic electrode/electrolyte interface, the region of excess charge at the interface consists of electrons (or holes) on the metallic side and of ions on the electrolyte side. In the case of a liquid/liquid interface, both charge regions are formed by ions: anions on one side and cations on the other.
