Effects of crystallization on micro-mechanical behavior of polyethylene nanocomposites using Raman spectroscopy Open
Recent work has shown that nanoparticles can be ordered in semicrystalline polymers by controlling the crystallization rate, specifically by forcing them to migrate to the amorphous regions of the lamellar morphology. Here, we study the mi…

Short-Range Order Enhances Strength and Tensile Ductility in Nanocrystalline Silver with Intercalation of Amorphous Nickel Nanolayers Open
Silver, known for its high thermal and electrical conductivity, is an ideal metal for thin-film electrode applications. Because alloying can negatively affect conductivity, enhancing the strength and resistance to strain poses a tremendous…

Revealing extreme twin-boundary shear deformability in metallic nanocrystals Open
Twinned nanocrystals exhibit approximately 364% shear strain via extensive twin boundary sliding.
Defect-driven selective metal oxidation at atomic scale Open
Nanoscale materials modified by crystal defects exhibit significantly different behaviours upon chemical reactions such as oxidation, catalysis, lithiation and epitaxial growth. However, unveiling the exact defect-controlled reaction dynam…

Strengthening Nanotwinned Metals beyond the Hall-Petch Limit Open
A research partnership program was conducted to study the roles of trace element segregation as a fundamentally new mechanism of grain-boundary and twin-boundary strengthening in nanocrystalline-nanotwinned face-centered-cubic silver metal…
Multiscale modeling of interfacial mechanical behaviours of SiC/Mg nanocomposites Open
The aim of this investigation is to predict the interface separation behavior of silicon carbide (SiC) reinforced magnesium (Mg) matrix composites via multiscale simulations. Interface models for SiC/Mg composites with different interface …
Size-dependent dislocation–twin interactions Open
Dislocation–twin interactions show a strong twin size dependence down to the smallest twin size limit.
Development of a semi-empirical potential for simulation of Ni solute segregation into grain boundaries in Ag Open
An Ag–Ni semi-empirical potential was developed to simulate the segregation of Ni solutes at Ag grain boundaries (GBs). The potential combines a new Ag potential fitted to correctly reproduce the stable and unstable stacking fault energies…
Segregation-affected yielding and stability in nanotwinned silver by microalloying Open
Small-scale mechanics of solute atom segregation and incipient plasticity in nanotwinned Ag containing trace concentrations of Cu were studied by using large-scale hybrid Monte-Carlo and molecular-dynamic simulations. It is found that solu…
Intrinsic nanotwin effect on thermal boundary conductance in bulk and single-nanowire twinning superlattices Open
Coherent twin boundaries form periodic lamellar twinning in a wide variety of\nsemiconductor nanowires, and are often viewed as near-perfect interfaces with\nreduced phonon and electron scattering behaviors. Such unique characteristics\nar…
