Crystallinity of nanoparticles
WebJul 24, 2024 · Non-classical crystallization suggests that crystals can grow with nanoparticles as a building block. In this case, the crystallization behavior depends on the size and charge of the nanoparticles. If charged nanoparticles (CNPs) are small enough, they become liquid-like and tend to undergo epitaxial recrystallization. Here, the size … WebJan 1, 2024 · The melting temperature increased with the number of nanoparticles, indicating that KHT and PFT nanoparticles act as heterogeneous nucleating agents, increase the crystallization temperature, and accelerate the formation of the crystal nucleus (Fig. 5.6). However, these nanoparticles decrease DSC crystallinity as they suppress the ...

Particle size is the external dimensions of a particle, and dispersity is a measure of the range of particle sizes in a sample. If the particle is elongated or irregularly shaped, the size will differ between dimensions, although many measurement techniques yield an equivalent spherical diameter based on the surrogate property being measured. Size can be calculated from physical prop…
