Capacitive storage devices allow for fast charge and discharge cycles, making them the perfect complements to batteries high power applications. Many materials display interesting capacitive properties when they are put in contact with ionic solutions despite their very different structures (surface) reactivity. Among them, nanocarbons most important practical applications, but many nanomaterials have recently emerged, such as conductive metal-organic frameworks, 2D materials, a wide variety of metal oxides. These heterogeneous complex electrode difficult model conventional approaches. However, development computational methods, incorporation machine learning techniques, increasing performance computing now us tackle these types systems. In this Review, we summarize current efforts direction. We show that depending on nature charging mechanisms, or combinations can provide desirable atomic-scale insight interactions at play. mainly focus two aspects: (i) study ion adsorption nanoporous which require extension constant potential molecular dynamics multicomponent systems, (ii) characterization Faradaic processes pseudocapacitors, involves use electronic structure-based methods. also discuss how developed simulation methods will bridges be made between double-layer capacitors pseudocapacitors future electricity devices.

By combining metal nodes and organic linkers, an infinite number of frameworks (MOFs) can be designed in silico. Therefore, when making new databases such hypothetical MOFs, we need to ensure that they not only contribute toward the growth count structures but also add different chemistries existing databases. In this study, a database ∼20,000 which are diverse terms their chemical design space─metal nodes, functional groups, pore geometries. Using machine learning techniques, visualized quantified diversity these structures. We find on adding our database, overall metrics improve, especially chemistry nodes. then assessed usefulness by evaluating performance, using grand-canonical Monte Carlo simulations, two important environmental applications─post-combustion carbon capture hydrogen storage. many perform better than widely used benchmark materials as Zeolite-13X (for post-combustion capture) MOF-5 storage). All developed properties, provided Materials Cloud encourage further use for other applications.

Machine learning models can provide fast and accurate predictions of material properties but often lack transparency. Interpretability techniques be used with black box solutions, or alternatively, created that are directly interpretable. We revisit datasets in several works demonstrate simple linear combinations nonlinear basis functions created, which have comparable accuracy to the kernel neural network approaches originally used. Linear solutions accurately predict bandgap formation energy transparent conducting oxides, spin states for transition metal complexes, elpasolite structures. how interpretable predictive highlight new insights found when a model understood from its coefficients functional form. Furthermore, we discuss recognize intrinsically may best route interpretability.

Despite decades of effort, no earth-abundant homogeneous catalysts have been discovered that can selectively oxidize methane to methanol. We exploit active learning simultaneously optimize activation and methanol release calculated with machine learning-accelerated density functional theory in a space 16 M candidate including novel macrocycles. By constructing macrocycles from fragments inspired by synthesized compounds, we ensure synthetic realism our computational search. Our large-scale search reveals low-spin Fe(II) compounds paired strong-field (e.g., P or S-coordinating) ligands among the best energetic tradeoffs between hydrogen atom transfer (HAT) release. This observation contrasts prior efforts focused on high-spin weak-field ligands. decoupling equatorial axial ligand effects, determine negatively charged are critical for more rapid higher-valency metals [i.e., M(III) vs M(II)] likely be rate-limited slow With full characterization barrier heights, confirm optimizing HAT does not lead large oxo formation barriers.
