BACKGROUND Interactions between inorganic nanoparticles (NPs) are central to a wide
spectrum of physical, chemical, and biological phenomena. An understanding of these …

A desire to optimise the production and performance of nanoparticle structured materials
has driven the development of increasingly accurate and fundamental models that describe …

This paper reviews the state-of-the-art contact force models for non-spherical particles,
which describe the relationship between the contact force and the geometrical, material, and …

Realizing and manipulating a fine dispersion of silica nanoparticles (NPs) in the polymer
matrix is always a great challenge. In this work, we first successfully synthesized N, N′-bis …

Zinc oxide (ZnO) has attracted much attention for various applications because of its unique
electrical, optical, magnetic and piezoelectric properties. ZnO nanowires (NWs) are often …

In this work, molecular dynamics simulations have been performed to explore the structural
evolution and underlying sintering mechanism of aluminum nanoparticles. The structural …

In this work, dynamic mechanical contact behaviors and sintering mechanism of Al
nanoparticles subjected to high-speed impact have been investigated using molecular …

The contact mechanics of individual, very small particles with other particles and walls is
studied using a nanoindenter setup that allows normal and lateral displacement control and …

Due to the breakdown of Derjaguin approximation at the nanoscale level apart from the
neglect of the atomic discrete structure, the underestimated number density of atoms, and …

In this work, interaction forces between two silica nanospheres after contact, including the
van der Waals (vdW) attraction, Born repulsion, and mechanical contact forces are studied …
