The Colloidal State01:29

The Colloidal State

182
The formation of a colloidal system is exemplified by an aqueous solution containing Cl− ions is introduced to another containing Ag+ ions, resulting in the precipitation of solid AgCl as extremely tiny crystals. Instead of settling out as a filterable precipitate, these crystals remain suspended in the liquid, showcasing a colloidal system.A colloidal system involves colloidal particles within the approximate range of 1 to 1000 nm in at least one dimension, dispersed in a medium called...

First Law: Particles in Two-dimensional Equilibrium

14.3K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.
Newton's first law tells us about...

First Law: Particles in One-dimensional Equilibrium

6.8K
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...

Metallic Solids02:37

Metallic Solids

16.4K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and...

Structures of Solids02:22

Structures of Solids

17.7K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Lattice Centering and Coordination Number

13.7K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.
Types of Unit Cells
Imagine taking a large number of identical...

Summary
This summary is machine-generated.

Controlling the kinetics of one-patch colloidal particles (Janus particles) is crucial for achieving highly ordered zigzag patterns. Experimental and simulation results highlight the importance of controlled growth for orientational order in colloidal monolayers.

Area of Science:

  • Colloidal science
  • Soft matter physics
  • Materials science

Background:

  • Janus particles exhibit unique orientational ordering in monolayers.
  • Controlling particle assembly is key to creating ordered materials.

Purpose of the Study:

  • To investigate the orientational order of one-patch Janus particles in a close-packed monolayer.
  • To understand the role of kinetics and inter-patch attraction in pattern formation.
  • To compare experimental findings with Monte Carlo simulations.

Main Methods:

  • Experimental self-assembly of hemispherically patched Janus particles.
  • Inducing directional growth via solvent phase transitions.
  • Monte Carlo simulations to model equilibrium order and phase transitions.
  • Varying patch size and inter-patch attraction strength.

Main Results:

  • A highly ordered zigzag stripe pattern was achieved through controlled directional growth.
  • Spontaneous ordering led to poorly ordered patterns, emphasizing kinetic control.
  • Patch size dependence of orientational order was observed experimentally.
  • Simulations revealed continuous transitions between different ordered states (zigzag, trimers, dimers) with decreasing attraction.

Conclusions:

  • Kinetics plays a vital role in achieving high orientational order in Janus particle monolayers.
  • Experimental results align with simulation predictions, with deviations attributed to nonuniform attractions.
  • The study provides insights into controlling colloidal self-assembly for ordered structures.
