Molecular Dynamics Simulation of β-HMX Crystal Morphology Induced by Polymer Additives

open access: yesCrystals, 2022
To simulate the crystal morphology of β-HMX crystallized in the presence of different polymer additives in the solution, a modified attachment energy model was used to simulate the crystal morphology of β-HMX recrystallized in PVA-DMSO solution when the ...

Detection and characterization of folded-chain clusters in the structured melt of isotactic polypropylene

open access: yesIUCrJ, 2021
Despite ceaseless efforts in past decades, the memory effect of semi-crystalline polymers has not been elucidated completely yet. An important reason why is that residual lamellar crystals in the structured melt are difficult to characterize.

Effect of synthesis time on plasmonic properties of Ag dendritic nanoforests

open access: yesIUCrJ, 2022
The effects of synthesis time on the plasmonic properties of Ag dendritic nanoforests on Si substrate (Ag-DNF/Si) samples synthesized through the fluoride-assisted galvanic replacement reaction were investigated.

Liquid crystal seed nucleates liquid–solid phase change in ceria nanoparticles [PDF]

open access: yes, 2015
Molecular dynamics (MD) simulation was used to explore the liquid–solid (crystal) phase change of a ceria nanoparticle. The simulations reveal that the crystalline seed, which spontaneously evolves and nucleates crystallisation, is a liquid rather than

Study on Utilization of Carboxyl Group Decorated Carbon Nanotubes and Carbonation Reaction for Improving Strengths and Microstructures of Cement Paste

open access: yesNanomaterials, 2016
Carbon nanotubes (CNTs) have excellent mechanical properties and can be used to reinforce cement-based materials. On the other hand, the reaction product of carbonation with hydroxides in hydrated cement paste can reduce the porosity of cement-based ...

Rheology of Aqueous Dispersions of Hydrogenated Castor Oil

open access: yesApplied Rheology, 2013
Three major hydrogenated castor oil crystal morphologies have been observed: fiber, rosette and irregular crystal. Due to the difficulty in obtaining samples with a single crystal morphology, rheological studies of suspensions containing mixtures of the ...

Phase Stability and Morphology of Gel Grown Crystals: The Case of CdCl2-bpp Polymeric System

open access: yesCrystals, 2019
A phenomenological study is carried out on a complex two-component diffusion-reacting system in gel, that is, the Cd-1,3-bis(4-pyridyl)propane (Cd-bpp) coordination polymer.
