Geometry-Dependent Atomic and Molecular Processes at Nanoscale Interfaces

Recent advances in nanofabrication and surface characterization have enabled unprecedented control over the geometry of surfaces and interfaces down to the atomic and molecular scale. At these dimensions, geometry is no longer merely a boundary condition: curvature, confinement, patterning, dimensionality, and nanoscale structuring can fundamentally modify the interactions of atoms and molecules with their environment and thereby affect their structure, dynamics, transport, and reactivity. Understanding these effects is a central question in physical chemistry, because interfacial geometry determines how bonds form and break, how energy is exchanged and dissipated, and how chemical selectivity emerges at structured surfaces.This Research Topic aims to bring together experimental and theoretical studies exploring how nanoscale geometry influences atomic and molecular interactions and processes. Particular emphasis is placed on situations in which geometrical features of an interface, such as confinement, curvature, edges, pores, periodic structures, roughness, or reduced dimensionality, give rise to behavior that differs from that at homogeneous or planar interfaces.The collection seeks to connect traditionally distinct areas of chemical physics, surface science, nanoscience, and quantum science. Relevant phenomena range from atomic and molecular scattering, diffraction, and quantum reflection to adsorption, desorption, energy transfer, dispersion interactions, chemical bonding and reactivity. Conversely, atomic and molecular probes can provide highly sensitive information about nanoscale structure and interface properties.We welcome Original Research, Review, Mini Review and Perspective articles on themes including, but not limited to:• Geometry-dependent atomic and molecular interactions;• Scattering, diffraction, and reflection from nanostructured surfaces;• Confinement and curvature effects on molecular structure, dynamics, and reactivity;• Adsorption, desorption, and energy transfer at structured interfaces;• Dispersion and fluctuation-induced interactions in complex geometries;• Atomic and molecular processes involving pores, edges, defects, two-dimensional materials, and other low-dimensional structures;• Atomic and molecular probes of nanoscale geometry;• Theoretical and computational approaches to geometry-dependent interactions and processes.By bringing together researchers from complementary disciplines, this Research Topic seeks to stimulate the exchange of ideas and foster new collaborations at the intersection of chemical physics, surface science, nanoscience, and quantum science.Topic Editor Martin Presselt is the co-founder and CEO of SciClus GmbH & Co.
