The Size and Shape Effects on the Melting Point of Nanoparticles Based on the Lennard-Jones Potential Function

Nanomaterials, 2021
A model is proposed to calculate the melting points of nanoparticles based on the Lennard-Jones (L-J) potential function. The effects of the size, the shape, and the atomic volume and surface packing of the nanoparticles are considered in the model.

Entanglements in polymer nanocomposites containing spherical nanoparticles. [PDF]

Soft Matter, 2016
We investigate the polymer packing around nanoparticles and polymer/nanoparticle topological constraints (entanglements) in nanocomposites containing spherical nanoparticles in comparison to pure polymer melts using molecular dynamics (MD) simulations ...

Size and shape dependent cohesive energy and melting temperature in semiconducting nanomaterials [PDF]

Discover Nano
Predicting thermophysical properties at the nanoscale remains challenging due to the lack of a unified model that simultaneously accounts for key factors such as atomic packing of the crystal lattice, surface-bond relaxation effects, and particle shape ...

PLA-PEG forming worm-like nanoparticles despite unfavorable packing parameter: formation mechanism, thermal stability and potential for cell internalization.

International journal of pharmaceutics, 2023
Most nanoparticles produced for drug delivery purposes are spherical. However, the literature suggests that elongated particles are advantageous, notably in terms of cellular uptake. Thus, we synthesized biocompatible polylactide-b-poly(ethylene glycol) (

Self-Assembly of Pluronic F127—Silica Spherical Core–Shell Nanoparticles in Cubic Close-Packed Structures [PDF]

Chemistry of Materials, 2015
A new ordered mesoporous silica material (COK-19) with cubic symmetry is synthesized by silicate polycondensation in a citric acid/citrate buffered micellar solution of Pluronic F127 triblock copolymer near neutral pH. SAXS, nitrogen adsorption, TEM, and electron tomography reveal the final material has a cubic close packed symmetry (Fm3̅m) with ...
