Abstract

In this work we report the characterization of AuPdCuNi decahedral nanoparticles using advanced microscopy and computational techniques. In addition to that, we are also proposing a new method to analyze asymmetrical HOLZ patterns. This new approach provides very accurate lattice spacing determinations. Electron Microscopy using Converging Beam Diffraction images together with Molecular Dynamics simulations results in significant insights about the structural properties of the AuCuPdNi decahedral nanoparticles, which correspond to an overall distorted FCC lattice, fitted to a BCT lattice with a=b=0.287 nm, and c=0.415 nm. Strain comes in two pairs of tetrahedra, each one with a different strain and the fifth pair with a different strain from the others.

期刊介绍： Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
