London Dispersion Forces in Molecules, Solids and Nano-structures An Introduction to Physical Models and Computational Methods

Author: John Dobson Format: Hardback Release Date: 01/04/2020

London dispersion interactions are responsible for numerous phenomena in physics, chemistry and biology. Recent years have seen the development of new, physically well-founded models, and dispersion-corrected density functional theory (DFT) is now a hot topic of research. This book is an overview of current understanding of the physical origin and modelling of London dispersion forces manifested at an atomic level. It covers a wide range of system, from small intermolecular complexes, to organic molecules and crystalline solids, through to biological macromolecules and nanostructures. In presenting a broad overview of the of the physical foundations of dispersion forces, the book provides theoretical, physical and synthetic chemists, as well as solid-state physicists, with a systematic understanding of the origins and consequences of these ubiquitous interactions.

Quantum Effects in Complex Systems Faraday Discussion

Quantum Effects in Complex Systems Faraday Discussion

Author: Royal Society of Chemistry Format: Hardback Release Date: 15/01/2020

Nuclear quantum effects such as zero-point energy conservation, tunnelling, non-adiabaticity and coherence play an important role in many complex chemical systems of technological and biological importance. Zero-point energy differences are key to understanding the experimentally-observed differences in the thermodynamic properties of normal and heavy water, while both theoretical and experimental work has highlighted the role of quantum tunnelling in enzyme-catalysed hydrogen transfer reactions. Photochemical reactions, involving multiple potential energy surfaces, are implicitly quantum-mechanical in nature, while recent spectroscopic investigations are providing new insight into the role of quantum coherence in the efficient energy transfer processes observed in photosynthetic centres. This volume brings together computational and experimental researchers who are interested in developing and applying methods to use in understanding the role of quantum effects in complex systems. The topics covered in this volume include: Quantum coherence in complex environments Spectroscopic signatures of quantum effects Zero-point energy and tunnelling Emerging opportunities and future directions

Computational Nanotoxicology Challenges and Perspectives

Computational Nanotoxicology Challenges and Perspectives

Author: Agnieszka Gajewicz Format: Hardback Release Date: 03/01/2020

The development of computational methods that support human health and environmental risk assessment of engineered nanomaterials (ENMs) has attracted great interest because the application of these methods enables us to fill existing experimental data gaps. However, considering the high degree of complexity and multifunctionality of ENMs, computational methods originally developed for regular chemicals cannot always be applied explicitly in nanotoxicology. This book discusses the current state of the art and future needs in the development of computational modeling techniques for nanotoxicology. It focuses on (i) computational chemistry (quantum mechanics, semi-empirical methods, density functional theory, molecular mechanics, molecular dynamics), (ii) nanochemoinformatic methods (quantitative structure-activity relationship modeling, grouping, read-across), and (iii) nanobioinformatic methods (genomics, transcriptomics, proteomics, metabolomics). It reviews methods of calculating molecular descriptors sufficient to characterize the structure of nanoparticles, specifies recent trends in the validation of computational methods, and discusses ways to cope with the uncertainty of predictions. In addition, it highlights the status quo and further challenges in the application of computational methods in regulation (e.g., REACH, OECD) and in industry for product development and optimization and the future directions for increasing acceptance of computational modeling for nanotoxicology.

The Fragment Molecular Orbital Method Practical Applications to Large Molecular Systems

The Fragment Molecular Orbital Method Practical Applications to Large Molecular Systems

Author: Dmitri Fedorov Format: Paperback / softback Release Date: 21/10/2019

Answering the need to facilitate quantum-chemical calculations of systems with thousands of atoms, Kazuo Kitaura and his coworkers developed the Fragment Molecular Orbital (FMO) method in 1999. Today, the FMO method can be applied to the study of whole proteins and protein-ligand interactions, and is extremely effective in calculating the properties of biological systems and molecular clusters. Providing a unique and accessible approach, The Fragment Molecular Orbital Method: Practical Applications to Large Molecular Systems is for those researchers eager to obtain useful information from electronic structure calculations of large systems, and for those who wish to know what can be elucidated with the calculations at present and in the near future. The text emphasizes the practical aspects, with as little mathematical detail as possible and in language that is easy to understand. The free modeling software Facio, in which FMO-related functions are implemented, is provided on the accompanying CD-ROM, which also provides input file samples, usage hints, annotated output from typical calculations, easy-to-follow tutorial material, and AppliGuide movies that show the sequence of mouse operations for data processing. The book encourages readers to perform their own calculations - describing the features of the freely available FMO programs (GAMESS and ABINIT-MP) and reviewing many successful applications of the FMO method to practical problems. Filled with practical advice from the inventors of the method and from world-renowned contributors, this reference provides general scientists with the foundation required to use FMO computational methods in a wide range of biomolecular applications, including drug design, protein-ligand binding, enzyme reactivity, and light-driven processes.

Photoinduced Molecular Dynamics in Solution Multiscale Modelling and the Link to Ultrafast Experiments

Photoinduced Molecular Dynamics in Solution Multiscale Modelling and the Link to Ultrafast Experiments

Author: Gianluca Levi Format: Hardback Release Date: 19/09/2019

This book explores novel computational strategies for simulating excess energy dissipation alongside transient structural changes in photoexcited molecules, and accompanying solvent rearrangements. It also demonstrates in detail the synergy between theoretical modelling and ultrafast experiments in unravelling various aspects of the reaction dynamics of solvated photocatalytic metal complexes. Transition metal complexes play an important role as photocatalysts in solar energy conversion, and the rational design of metal-based photocatalytic systems with improved efficiency hinges on the fundamental understanding of the mechanisms behind light-induced chemical reactions in solution. Theory and atomistic modelling hold the key to uncovering these ultrafast processes. Linking atomistic simulations and modern X-ray scattering experiments with femtosecond time resolution, the book highlights previously unexplored dynamical changes in molecules, and discusses the development of theoretical and computational frameworks capable of interpreting the underlying ultrafast phenomena.
