Transmission electron microscopy has functioned for decades as a platform for in situ
observation of materials and processes with high spatial resolution. Yet, the dynamics often …

We present a new class of reactive materials termed “inert-mediated reactive
multilayers”(IMRMs) that use inert material to decouple the effects of chemistry and …

We present an atomistic level description of the reaction mechanisms in thermally ignited
samples of reactive core/shell Ni/Al wires. The combination of very long simulation times (up …

We use molecular dynamics simulations to characterize the chemical processes resulting
from the shock compaction of a loosely packed granular reactive composite of Ni and Al. For …

Hexagonal close-packed (hcp) Ni exists only on a nanometric scale and readily converts
into the stable face-centered cubic (fcc) polymorph. This work reports a spontaneous …

The synthesis of amorphous Ni (a-Ni) using a liquid-phase chemical reduction approach is
reported. Detailed structural analysis indicates that this method allows for efficient fabrication …

Self-propagating reactions in Ni/Al nanolaminates have been widely studied for their high
combustion temperatures surpassing 1900 K and rapid combustion wave speeds exceeding …

We develop the second nearest-neighbor modified embedded atom method to describe the
Cu/Pd system. The potential parameters are determined by fitting cohesive energy, lattice …

Shock-induced consolidations of Ni/Al nanoparticles, including the consolidation behavior,
exothermic reaction, intermetallic compound formation, and spallation, were systematically …

Molecular dynamics simulations of reactions in Al/Ni layered systems have been carried out
under isothermal conditions for a wide range of temperatures and several system sizes. An …
