Book excerpt: Discover how the latest computational tools are building our understanding of particle interactions and leading to new applications With this book as their guide, readers will gain a new appreciation of the critical role that particle interactions play in advancing research and developing new applications in the biological sciences, chemical engineering, toxicology, medicine, and manufacturing technology The book explores particles ranging in size from cations to whole cells to tissues and processed materials. A focus on recreating complex, real-world dynamical systems helps readers gain a deeper understanding of cell and tissue mechanics, theoretical aspects of multiscale modeling, and the latest applications in biology and nanotechnology. Following an introductory chapter, Multiscale Modeling of Particle Interactions is divided into two parts: Part I, Applications in Nanotechnology, covers: Multiscale modeling of nanoscale aggregation phenomena: applications in semiconductor materials processing Multiscale modeling of rare events in self-assembled systems Continuum description of atomic sheets Coulombic dragging and mechanical propelling of molecules in nanofluidic systems Molecular dynamics modeling of nanodroplets and nanoparticles Modeling the interactions between compliant microcapsules and patterned surfaces Part II, Applications in Biology, covers: Coarse-grained and multiscale simulations of lipid bilayers Stochastic approach to biochemical kinetics In silico modeling of angiogenesis at multiple scales Large-scale simulation of blood flow in microvessels Molecular to multicellular deformation during adhesion of immune cells under flow Each article was contributed by one or more leading experts and pioneers in the field. All readers, from chemists and biologists to engineers and students, will gain new insights into how the latest tools in computational science can improve our understanding of particle interactions and support the development of novel applications across the broad spectrum of disciplines in biology and nanotechnology.

Book Synopsis Multiscale Modeling and Control of Crystal Shape and Size Distributions: Accounting for Crystal Aggregation, Evaluation of Continuous Crystallization Systems and Run-to-run Control by : Joseph Sangil Kwon

Download or read book Multiscale Modeling and Control of Crystal Shape and Size Distributions: Accounting for Crystal Aggregation, Evaluation of Continuous Crystallization Systems and Run-to-run Control written by Joseph Sangil Kwon. This book was released on 2015. Available in PDF, EPUB and Kindle. Book excerpt: Crystallization plays a vital role in separation and purification methods for the production of therapeutic drugs. Considering the fact that crystal size and shape distributions have a significant influence on the bioavailability of drugs such as the dissolution rate, filterability, and stability as a carrier to the target site, the production of crystals with desired size and shape distributions is of particular interest to the pharmaceutical industry. Motivated by these considerations, this dissertation focuses on the development of a multiscale modeling and simulation framework for crystallization processes that elucidates the relationship between molecular-level processes like crystal nucleation, growth and aggregation and macroscopically-observable process behavior and allows computing optimal design and operation conditions. Using protein crystallization as a model system, the multiscale framework encompasses: a) equilibrium Monte-Carlo modeling for computing solid-liquid phase diagrams and determining initial crystallization conditions that favor crystal nucleation, b) kinetic Monte-Carlo modeling for simulating crystal growth and aggregation and predicting the evolution of crystal shape distribution, and c) integrated multiscale computation linking molecular-level models and continuous-phase macroscopic equations, covering both batch and continuous crystallization systems. The multiscale model parameters and predictions are calibrated and tested with respect to available experimental data. Then, this dissertation addresses model predictive controller designs that utilize the insights and results from the multiscale modeling work and real-time measurements of solute concentration and temperature to manipulate crystallizer conditions that lead to the production of crystals with desired size and shape distributions. To enhance the ability of the predictive controller to deal with batch-to-batch parametric drifts, a common problem in industrial crystallization owing to changes, for example, in the pH level or impurity concentration in the feedstock container, a run-to-run-based model parameter estimation scheme will be presented that uses moving horizon estimation principles to update the predictive controller model parameters after each batch and leads to the consistent production of crystals of desired shape at the end of each batch.

Book Synopsis Silicon, Germanium, and Their Alloys by : Gudrun Kissinger

Download or read book Silicon, Germanium, and Their Alloys written by Gudrun Kissinger. This book was released on 2014-12-09. Available in PDF, EPUB and Kindle. Book excerpt: Despite the vast knowledge accumulated on silicon, germanium, and their alloys, these materials still demand research, eminently in view of the improvement of knowledge on silicon–germanium alloys and the potentialities of silicon as a substrate for high-efficiency solar cells and for compound semiconductors and the ongoing development of nanodevices based on nanowires and nanodots. Silicon, Germanium, and Their Alloys: Growth, Defects, Impurities, and Nanocrystals covers the entire spectrum of R&D activities in silicon, germanium, and their alloys, presenting the latest achievements in the field of crystal growth, point defects, extended defects, and impurities of silicon and germanium nanocrystals. World-recognized experts are the authors of the book’s chapters, which span bulk, thin film, and nanostructured materials growth and characterization problems, theoretical modeling, crystal defects, diffusion, and issues of key applicative value, including chemical etching as a defect delineation technique, the spectroscopic analysis of impurities, and the use of devices as tools for the measurement of materials quality.
