Two Components: Liquid–Liquid Systems01:27

Two Components: Liquid–Liquid Systems

A pressure-composition phase diagram explicitly describes the behavior of an ideal solution of two volatile liquids under varying pressures and compositions. A pressure-composition diagram has two main curves. The bubble point curve represents the plot of pressure versus liquid mole fraction. It indicates the pressure at which the first bubble of vapor forms from the liquid phase as the system pressure decreases.The dew point curve is the pressure versus vapor mole fraction. It indicates the...
Phase Diagrams02:39

Phase Diagrams

A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...
Liquid–Solid Solutions01:29

Liquid–Solid Solutions

The process of a solid dissolving in a liquid to form a solution is governed by the solubility limit, which is the maximum amount of the solid substance, or solute, that can be dissolved in a specific volume of the liquid or solvent. As the solute dissolves, it reaches a point where no more solute can be dissolved at a given temperature - this is known as the saturation point. However, if further solute is added and it manages to dissolve, the solution becomes supersaturated. Supersaturated...
Newman Projections02:06

Newman Projections

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as conformers.
The Electrical Double Layer01:30

The Electrical Double Layer

In the region where two bulk phases meet, an intricate electric charge distribution arises due to charge transfer, ion adsorption, molecular orientation, and charge distortion. This complex distribution is commonly referred to as the electrical double layer.When a solid electrode interfaces with ions in an electrolyte solution, the speed of electron transfer dictates the rates of oxidation and reduction. The electrode acquires a charge through the escape of atoms into the solution as cations or...
Network Covalent Solids02:18

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Area of Science:

  • Surface Science
  • Materials Science
  • Nanotechnology

Background:

  • Understanding liquid-solid interfaces is crucial for materials science.
  • Hexadecane (C16H34) behavior on highly oriented pyrolytic graphite (HOPG) is not well characterized at the molecular level.
  • Previous studies using scanning tunneling microscopy have not reported detailed structural observations for this alkane at the liquid/graphite interface.

Purpose of the Study:

  • To achieve a 3-dimensional description of the liquid hexadecane/highly oriented pyrolytic graphite interface at room temperature.
  • To investigate the molecular structure of hexadecane layers adsorbed on a graphite surface.
  • To compare experimental findings with molecular dynamics simulations.

Main Methods:

  • Utilizing an atomic force microscope (AFM) equipped with a quartz tuning fork (QTF) sensor.
  • Performing force/distance curve measurements to probe interfacial forces and layer structures.
  • Employing AFM for high-resolution imaging of the liquid/solid interface.

Main Results:

  • A distinct lamellar structure was observed for the C16H34 monolayer in direct contact with the graphite substrate.
  • The second adsorbed layer exhibited weak corrugations, indicative of lamella boundaries.
  • Force/distance curves showed multiple oscillations, with a layer spacing of 0.38 nm for the first layer and 0.4 nm for subsequent layers.
  • These experimental results align well with molecular dynamics simulations of alkane/solid interfaces.

Conclusions:

  • Atomic force microscopy with a QTF sensor provides detailed 3D structural information at liquid/solid interfaces.
  • Hexadecane forms ordered lamellar structures on highly oriented pyrolytic graphite, challenging previous observations.
  • The observed layer spacing is consistent with molecular packing and dynamics at the interface.
