Crystal Growth: Principles of Crystallization01:25

Crystal Growth: Principles of Crystallization

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 – the...
Step-Growth Polymerization: Overview01:03

Step-Growth Polymerization: Overview

Step-growth or condensation polymerization is a stepwise reaction of bi or multifunctional monomers to form long-chain polymers. As all the monomers are reactive, most of the monomers are consumed at the early stages of the reaction to form small chains of reactive oligomers, which then combine to form long polymer chains in the late stages. Hence, the reaction has to proceed for a long time to achieve high molecular weight polymers.
Many natural and synthetic polymers are produced by...
Recrystallization: Solid–Solution Equilibria01:10

Recrystallization: Solid–Solution Equilibria

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...
Cationic Chain-Growth Polymerization: Mechanism00:57

Cationic Chain-Growth Polymerization: Mechanism

The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the generated carbocation,...

Summary
This summary is machine-generated.

Researchers developed a self-seeding technique to create arrays of identical polymer crystals. These "cloned" crystals inherit orientation from a single parent crystal, a feat not possible with traditional materials.

Area of Science:

  • Polymer Science
  • Materials Science
  • Crystallography

Background:

  • Conventional crystals lose molecular correlations and long-range order upon melting, preventing inheritance of features in regrown crystals.
  • Polymers exhibit a wide melting temperature range, allowing for unique phenomena like simultaneous melting and crystallization.
  • This contrasts with materials with sharp melting points where recrystallization erases initial structural information.

Purpose of the Study:

  • To introduce a self-seeding technique for generating orientation-correlated polymer crystals.
  • To achieve uniform size and shape ('clones') in polymer crystallites.
  • To investigate the inheritance of crystal orientation and control over crystal density and location.

Main Methods:

  • Utilizing a self-seeding technique on polymer crystallites.
  • Controlling the thermal history of an initial single crystal.
  • Observing the generation of arrays of polymer crystals with inherited orientation.

Main Results:

  • Successful generation of arrays of orientation-correlated polymer crystals ('clones') from a single crystal.
  • Demonstrated inheritance of orientation from the initial crystal to the cloned crystals.
  • Showed that crystal number density and location can be influenced by the starting crystal's thermal history.

Conclusions:

  • The self-seeding technique enables the creation of polymer crystal arrays with inherited orientation and controlled characteristics.
  • This phenomenon is attributed to the coexistence of variable fold lengths in metastable crystalline lamellae within polymers.
  • The findings offer new possibilities for controlling polymer crystalline structures and properties.
