Download or read book Biological Crystallization written by Jaime Gómez Morales and published by MDPI. This book was released on 2019-09-23 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: For at least six hundred million years, life has been a fascinating laboratory of crystallization, referred to as biomineralization. During this huge lapse of time, many organisms from diverse phyla have developed the capability to precipitate various types of minerals, exploring distinctive pathways for building sophisticated structural architectures for different purposes. The Darwinian exploration was performed by trial and error, but the success in terms of complexity and efficiency is evident. Understanding the strategies that those organisms employ for regulating the nucleation, growth, and assembly of nanocrystals to build these sophisticated devices is an intellectual challenge and a source of inspiration in fields as diverse as materials science, nanotechnology, and biomedicine. However, “Biological Crystallization” is a broader topic that includes biomineralization, but also the laboratory crystallization of biological compounds such as macromolecules, carbohydrates, or lipids, and the synthesis and fabrication of biomimetic materials by different routes. This Special Issue collects 15 contributions ranging from biological and biomimetic crystallization of calcium carbonate, calcium phosphate, and silica-carbonate self-assembled materials to the crystallization of biological macromolecules. Special attention has been paid to the fundamental phenomena of crystallization (nucleation and growth), and the applications of the crystals in biomedicine, environment, and materials science.

Volume IA highlights thermodynamics and kinetics. After historical introduction of the crystal growth, phase equilibria, defect thermodynamics, stoichiometry, and shape of crystal and structure of melt are described. Then, the most fundamental and basic aspects of crystal growth are presented, along with the theories of nucleation and growth kinetics. In addition, the simulations of crystal growth by Monte Carlo, ab initio-based approach and colloidal assembly are thoroughly investigated.

In addition, an introduction to morphological stability is given and the phase-field model is explained with comparison to experiments. The field of nanocrystal growth is rapidly expanding and here the growth from vapor is presented as an example. For the advancement of life science, the crystal growth of protein and other biological molecules is indispensable and biological crystallization in nature gives many hints for their crystal growth.

Available in PDF, EPUB and Kindle. Book excerpt: Deoxyribonucleic acid (DNA) has emerged as an attractive building material for creating complex architectures at the nanometer scale that simultaneously affords versatility and modularity. Particularly, the programmability of DNA enables the assembly of basic building units into increasingly complex, arbitrary shapes or patterns. With the expanding complexity and functionality of DNA toolboxes, a quantitative understanding of DNA self-assembly in terms of thermodynamics and kinetics, will provide researchers with more subtle design guidelines that facilitate more precise spatial and temporal control. This dissertation focuses on studying the physicochemical properties of DNA tile-based self-assembly process by recapitulating representative scenarios and intermediate states with unique assembly pathways. First, DNA double-helical tiles with increasing flexibility were designed to investigate the dimerization kinetics. The higher dimerization rates of more rigid tiles result from the opposing effects of higher activation energies and higher pre-exponential factors from the Arrhenius equation, where the pre-exponential factor dominates. Next, the thermodynamics and kinetics of single tile attachment to preformed "multitile" arrays were investigated to test the fundamental assumptions of tile assembly models. The results offer experimental evidences that double crossover tile attachment is determined by the electrostatic environment and the steric hindrance at the binding site. Finally, the assembly of double crossover tiles within a rhombic DNA origami frame was employed as the model system to investigate the competition between unseeded, facet and seeded nucleation. The results revealed that preference of nucleation types can be tuned by controlling the rate-limiting nucleation step.The works presented in this dissertation will be helpful for refining the DNA tile assembly model for future designs and simulations. Moreover, the works presented here could also be helpful in understanding how individual molecules interact and more complex cooperative bindings in chemistry and biology. The future direction will focus on the characterization of tile assembly at single molecule level and the development of error-free tile assembly systems.

Download or read book Self assembly Dynamics and Energetics at the Solution solid Interface written by Kirill Gurdumov and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive investigation on the formation dynamics and energetics of adlayer formation at the at the solution/solid interface has been performed using scanning tunneling microscopy (STM) with a custom solution flow cell design that offers new insight into the self-assembly process. Understanding the formation kinetics and thermodynamics of self-assembled monolayers (SAM) provides insight into the delicate balance of intermolecular forces on the molecular scale. We herein investigate the growth, dynamics, and stability of a model non-covalent self-assembler -- Co(II) octaethylporphyrin at the solution/solution interface on the HOPG and Au(111) surfaces. Real-time imaging of the nucleation and growth of the self-assembled layer was captured and studied by in-situ STM, and further explored using computational methods. A custom STM solution flow cell was designed and implemented to allow for in-situ monitoring of self-assembly at very low concentrations and with volatile solvents. Flow studies at low concentration provide insight into early-stage kinetics and structural formation of a SAM. It was found that the choice of organic solvent plays a dramatic role in the kinetics and structure of the SAM. These results, in turn, provide insight into the balance of the intermolecular forces driving the self-assembly. The role of the solvent was particularly strong in the case of 1,2,4-trichlorobenzene (TCB) on both HOPG and Au(111). Under TCB, a very stable rectangular structure is formed and stabilized by solvent-incorporation. A transition to a solvent free pseudo-hexagonal structure was only observed when extremely high concentrations of porphyrin were present in solution. Similarly, in the case of CoOEP adsorbed on Au(111) under toluene, a solvent-incorporated rectangular structure was observed that, like the TCB case, transitioned into a pseudo-hexagonal structure, but this transition occurred at much lower concentrations of porphyrin. Toluene co-adsorption was not observed on HOPG. When deposited from decane, a short-lived pseudo-rectangular structure was observed on Au(111) but not on HOPG. Only the pseudo-hexagonal structure was observed in the porphyrin adlayer when 1-phenyloctane were used as a solvent. On HOPG, mixed solvent competition was tested and gave further insight into the thermodynamic and kinetic roles that solvents play in self-assembly.
