Low-energy electron diffraction effects at complex interfaces
… a tool to study electron-stimulated processes at complex interfaces. The electron diffraction in each complex interface is theoretically treated by a multiple scattering formalism for quantitative analysis. Mathematical descriptions of electron-stimulated processes and a multiple scattering …

Modelling and simulation in tribology of complex interfaces
… of surfaces in relative motion and involves complex interactions over multiple length and time scales. Therefore, friction, lubrication and wear of materials are intrinsically highly multiphysics and multiscale phenomena. Several modelling and simulation tools have been developed in the last …

Machine Learning Force Fields for Modelling Reactions at Complex Interfaces
… we explore how MLFFs can be used to model complex reactive systems. We examine both catalytic reactions at oxide interfaces and carbon capture in porous materials. A key obstacle to the widespread use of MLFFs for complex systems is the need to curate relevant training datasets that lead to …

Adsorption & Adhesion of Asphaltenes at Complex Interfaces: An AFM Approach
Asphaltenes are the heaviest fraction of crude oil, pinpointed as the culprit for the fouling of components throughout the hydrocarbon value chain. The ill-defined nature of asphaltenes has challenged scientists and industry alike, to determine their molecular composition and mitigate their effects …

Exploring and Evaluating Task Sequences for System Control Interfaces in Immersive Virtual Environments
… critical, but largely unexplored task in 3D user interfaces (3DUIs) for immersive virtual environments (IVEs). System control techniques are normally encompassed by complex interfaces that define how these interaction techniques fit together, which we call system control interfaces (SCIs). …

The Effect of Growth Method on GaN Films and Their Interfaces with CdTe and CdS
This work has analyzed the complex interfaces of GaN and InGaN grown by sputter deposition and GaN grown by metal-organic chemical vapor deposition (MOCVD) with CdTe and CdS. First, the GaN and InGaN films were characterized by AFM and XRD, and it has been shown that the MOCVD samples have a very …
