Crystal Growth: Principles of Crystallization

5.3K
Crystallization is a phase transformation process in which crystals are precipitated from a supersaturated solution or formed from other sources. During crystallization, atoms or molecules arrange themselves into a well-defined, rigid crystal lattice to minimize energy.
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...

Recrystallization: Solid–Solution Equilibria

4.1K
Recrystallization is a purification technique used to separate impurities from solid compounds. In this technique, no chemical reactions occur. Instead, it exploits physical properties only, specifically, the solubility differences between the desired compound and impurities, either at a single temperature or at different temperatures, and under other selected conditions. The solid-solution equilibrium (solubility equilibrium) of each component in the solution represents a binary phase...

Exponential Growth

76
Bacterial populations exhibit exponential growth when conditions such as nutrient availability and temperature are favorable. In this phase, cells reproduce through binary fission, where each cell divides into two identical daughter cells. This process causes the population to double at regular intervals, resulting in a growth rate that is directly proportional to the current number of cells. As the population increases, the number of new cells formed during each generation also grows, creating...

Exponential Equations for Modeling Growth

269
Exponential models are essential for describing rapid, multiplicative changes in natural systems, such as population growth. When a population doubles at regular intervals, the process can be modeled using a suitable base. For instance, a bacterial culture that doubles every three hours follows the model n(t)=n0⋅2t/3, where n(t) is the population at the time t.A more general model uses the natural base e, especially for continuous growth. This takes the form n(t)=n0⋅ert, where r is...

Exponential Equations with Logarithms: Problem Solving

200
In ecological studies, exponential models are often used to predict how populations grow over time under favorable conditions. These models assume that the growth rate is proportional to the current population, leading to continuous and compounding increases.The model expresses the population as a function of time, combining the initial population with a growth factor raised to an exponent involving the growth rate and time. To estimate how long it takes for a population to reach a specific...

Area of Science:

  • Biomineralization
  • Geochemistry
  • Materials Science

Background:

  • Coral skeletons are built from aragonite (CaCO₃) through transient precursor phases.
  • The precise dynamics of these early-stage transformations in coral biomineralization are not fully understood.

Purpose of the Study:

  • To investigate the dynamics and mineral phases involved in coral skeleton formation.
  • To understand the kinetics governing biomineralization in corals under varying seawater pH.

Main Methods:

  • Utilized time-independent myriad mapping (MM) at 50 nm resolution.
  • Mapped five mineral phases near the skeleton surface of Stylophora pistillata corals.
  • Analyzed coral samples grown in varying seawater pH conditions.

Main Results:

  • All identified precursors, both crystalline and amorphous, showed a consistent exponential decay from the growth front with a decay length of 0.7 ± 0.1 μm.
  • This decay was independent of time, phase, or seawater pH.
  • The dominant precursor identified was crystalline calcium carbonate hemihydrate (CCHH, CaCO₃·½H₂O), not amorphous phases.
  • Calculated a decay time of 5.1 ± 0.5 minutes based on spatial decay and skeleton growth rate.

Conclusions:

  • Coral biomineralization is governed by exponential crystallization kinetics.
  • Calcium carbonate hemihydrate is the primary precursor in coral skeleton formation.
  • These kinetics may be a common feature in various biogenic, geologic, and synthetic systems.
