Abstract

Atomic force microscopy based power spectrum density (PSD) method along with conventional methods such as line, grain height, root mean square (rms) roughness, is used to probe complex Hg–Au interactions i.e. the amalgamation of smooth gold nanostructures (Au–ns) and partial dissolution of irregular edges of interconnecting Au–ns networks due to Hg. We have demonstrated for the first time the use of the PSD method to gain significant insights into the directional anisotropy of resultant Hg–Au–ns and the range of Au–ns responsible.

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.
