Multiscale Modeling and Data Science in Materials, Energy and Catalysis

As in many other areas of materials science, modern computational science has become a key contributor in the quest to quantitatively understand and tailor molecular-level mechanisms underlying macroscopic phenomena and functionalities in catalysis and energy applications, ultimately enabling a rational design of novel catalysts, energy suppliers and improved production strategies. Of particular relevance are hierarchical approaches that link the insights that modeling and simulation can provide across all relevant length and time scales. At the molecular level, first-principles electronic-structure calculations unravel the making and breaking of chemical bonds. At the mesoscopic scale, statistical simulations account for the interplay between all elementary processes involved in the catalytic cycle, and at the macroscopic scale continuum theories yield the effect of heat and mass transfer, ultimately scaling up to a plant or device-wide simulation. A comprehensive control of catalytic and energy processes requires combining all of these facets and thus necessitates novel methodological approaches that integrate the various levels of theory into one multiscale simulation. At present, corresponding developments are further fueled by the fusion with emerging techniques from machine learning and artificial intelligence. Modelling and simulation, and in particular powerful virtual computational screening approaches, create vasts amounts of data. Efficiently extracting the knowledge contained in this data requires optimized data representations for the chemical problems at hand (feature engineering) that then enable modern data analytics (classification, regression, network analysis). Vice versa, machine learning and especially active learning concepts are key to minimize the computationally intense generation of first-principles data required as foundation for predictive-quality (multiscale) models.
