Available in PDF, EPUB and Kindle. Book excerpt: Täglich benutzen wir Schalter, um strombetriebene Geräte an- und abzuschalten und kein Compuer würde ohne sie funktionieren. Nach den gleichen Prinzipien funktionieren auch molekulare Schalter, die unter dem Einfluß ihrer Umwelt zwischen zwei definierten Zuständen wechseln können. Im Gegensatz zu den gewöhnlichen Schaltern sind molekulare Schalter aber außerordentlich klein und ihre Anwendung in der Nanotechnologie, Biomedizin und im Computerchipdesign öffnet neue Horizonte. Im vorliegenden Zweibänder berichten Herausgeber und Autoren über molekulare Schalter aus Katenanen und Rotaxanen, Fulgiden, Flüssigkristallen und Polypeptiden. Die Bandbreite der behandelten Themen reicht von chiroptischen Schaltern über multifunktionale Systeme bis hin zu molekularen logischen Schaltungen. Chemiker und Materialwissenschaftler in Industrie und Hochschule, die sich für einen der innovativsten Bereiche ihrer Wissenschaft interessieren, werden dieses Buch mit Gewinn lesen!
Download or read book The Molecular Switch written by Rob Phillips and published by Princeton University Press. This book was released on 2020-09 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: A signature feature of living organisms is their ability to carry out purposeful actions by taking stock of the world around them. To that end, cells have an arsenal of signaling molecules linked together in signaling pathways, which switch between inactive and active conformations. The Molecular Switch articulates a biophysical perspective on signaling, showing how allostery—a powerful explanation of how molecules function across all biological domains—can be reformulated using equilibrium statistical mechanics, applied to diverse biological systems exhibiting switching behaviors, and successfully unify seemingly unrelated phenomena. Rob Phillips weaves together allostery and statistical mechanics via a series of biological vignettes, each of which showcases an important biological question and accompanying physical analysis. Beginning with the study of ligand-gated ion channels and their role in problems ranging from muscle action to vision, Phillips then undertakes increasingly sophisticated case studies, from bacterial chemotaxis and quorum sensing to hemoglobin and its role in mammalian physiology. He looks at G-protein coupled receptors as well as the role of allosteric molecules in gene regulation. Phillips concludes by surveying problems in biological fidelity and offering a speculative chapter on the relationship between allostery and biological Maxwell demons. Appropriate for graduate students and researchers in biophysics, physics, engineering, biology, and neuroscience, The Molecular Switch presents a unified, quantitative model for describing biological signaling phenomena.
Download or read book Molecular Switches written by A. Malcolm Campbell and published by Momentum Press. This book was released on 2016-04-21 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the concept of emergent properties, which are unexpected traits found only when two or more biological components interact. Experimental evidence of several emergent properties explains how hemoglobin can act like a high affinity oxygen carrier some times and then switch to a low affinity carrier exactly when and where it should. The second example presents how one particular virus determines whether it should stay latent within its host or whether it should kill its host and spread its progeny into the environment. The final example looks at the surprising properties that emerge as a consequence of random behaviors at the molecular level. It is unlikely that many people are aware of these unexpected behaviors that come from non-living molecules based on their structures.
Download or read book Molecular and Nano Electronics Analysis Design and Simulation written by Jorge M. Seminario and published by Elsevier. This book was released on 2006-10-24 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of Molecular and Nano Electronics: Analysis, Design and Simulation is to draw together contributions from some of the most active researchers in this new field in order to illustrate a theory guided-approach to the design of molecular and nano-electronics. The field of molecular and nano-electronics has driven solutions for a post microelectronics era, where microelectronics dominate through the use of silicon as the preferred material and photo-lithography as the fabrication technique to build binary devices (transistors). The construction of such devices yields gates that are able to perform Boolean operations and can be combined with computational systems, capable of storing, processing, and transmitting digital signals encoded as electron currents and charges. Since the invention of the integrated circuits, microelectronics has reached increasing performances by decreasing strategically the size of its devices and systems, an approach known as scaling-down, which simultaneously allow the devices to operate at higher speeds. * Provides a theory-guided approach to the design of molecular and nano-electronics* Includes solutions for researchers working in this area* Contributions from some of the most active researchers in the field of nano-electronics
Download or read book Photofunctionalization of Molecular Switch Based on Pyrimidine Ring Rotation in Copper Complexes written by Michihiro Nishikawa and published by Springer Science & Business Media. This book was released on 2013-12-16 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed description of photofunctionalization of molecular switch based on pyrimidine ring rotational isomerization in copper complexes bearing two bidentate ligands. The most important features of this work focus on the properties associated with the rotational isomerization based on the two possible coordination geometries at the copper center derived from two nitrogen atoms on the unsymmetrically substituted pyrimidine ring. The functions of systems such as dual emission and redox potential switching based on photo-driven rotation will be of particular interest to readers. Both the functions and the procedures for proving these phenomena are beneficial for the development of more functionalized systems based on material science, molecular science, nanoscience, nanotechnology, electrochemistry, photochemistry, coordination chemistry, physical chemistry, and related disciplines. The finding elucidated here holds promise for handling the photoprocesses of metal complexes, valid for both applications and novel properties. This system is expected make it possible to extract an electrochemical potential response from molecular switches, aiming to simulate the five senses of human beings at a single molecular level.

Download or read book Molecular Machines and Motors written by Alberto Credi and published by Springer. This book was released on 2014-09-02 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cutting-edge advances in this research field are nicely pictured in the chapters of this volume. They come from world’s leading laboratories engaged in the development of molecular machines and are authored by some of the most respected scientists in the field. This volume shows, on the one hand, the level of ingenuity and technical capability reached in the construction of artificial nanomachines roughly two decades after their inception. On the other hand, it conveys the excitement about the enormous opportunities as well as the challenges this research area presents, as the interest of researchers is shifting from ensemble to single-molecule measurements and from homogeneous to heterogeneous environments. Indeed, as Feynman said “when we have some control of the arrangement of things on a molecular scale, we will get an enormously greater range of possible properties that substances can have.” Although the answer to the “when” question is not easy to find, there is no doubt that artificial molecular machines and motors will lead to a wide variety of applications which we cannot even envisage today. The Nobel Prize in Chemistry 2016 was awarded jointly to Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa "for the design and synthesis of molecular machines". Both Jean-Pierre Sauvage and Bernard L. Feringa contributed to this volume. The goal of each thematic volume in this series is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole.
