Download or read book Nitroxides written by Gertz I. Likhtenshtein and published by John Wiley & Sons. This book was released on 2008-06-25 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering all aspects of this field, this volume also critically discusses recent results obtained with the use of nitroxides, while providing an analysis of future developments. Written by a group of scientists with long-term experience in investigating the chemistry, physicochemistry, biochemistry and biophysics of nitroxides, the book is not intended as an exhaustive survey of each topic, but rather a discussion of their theoretical and experimental background, as well as recent advances. The first four chapters expound the general theoretical and experimental background and the advantages of modern ESR technique. Chapter 5 focuses on fundamentals and recent results in the preparation and basic chemical properties, while the next two chapters briefly outline principles and current results in nitroxides as spin probes, and as redox probes and spin traps. These chapters form the basis for the subsequent more detailed studies of nitroxides in physicochemistry, while the final chapters concentrate on the advantages of magnetic materials on the basis of nitroxides. Finally, the concluding chapter considers the rapidly developing field of biomedical, therapeutic and clinical applications. With more than 1,100 references to essential literature, this volume provides fundamental knowledge of instrumentation, data interpretation, capacity and recent advantages of nitroxide applications, allowing readers to understand how nitroxides can help them in solving their own problems.

Download or read book Rotational Spectra and Molecular Structure written by James E. Wollrab and published by Academic Press. This book was released on 2013-10-22 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical Chemistry, A Series of Monographs: Rotational Spectra and Molecular Structure covers the energy levels and rotational transitions. This book is divided into nine chapters that evaluate the rigid asymmetric top molecules and the nuclear spin statistics for asymmetric tops. Some of the topics covered in the book are the asymmetric rotor functions; rotational transition intensities; classes of molecules; nuclear spin statistics for linear molecules and symmetric tops; and classical appearance of centrifugal and coriolis forces. Other chapters deal with the energy levels and effects of centrifugal distortion, as well as the internuclear distance and moments of inertia. The discussion then shifts to the coriolis coupling effects on rotational constants and the perturbation treatment of vibration-rotational Hamiltonian. The last chapter is devoted to the examination of origin of the quadrupole interaction. The book can provide useful information to chemists, physicists, electrical engineers, students, and researchers.

This book was released on 2009-06-22 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aim of this volume is to clarify the relationship between molecular structure and function of tight junction proteins, as well as their regulation and their role in diseases. Current research may form a basis for future diagnostic and therapeutic approaches to diseases which seem to have not much in common but are characterized by defects of organ barriers, like Crohn's disease, renal hypertension, inner ear deafness, and cancerous diseases. Topics include the functions of distinct tight junction proteins as barrier or channel formers for solutes and water, characteristics of the tight junction in inflammatory bowel diseases, posttranslational modifications of tight junction proteins, the relation between renal tight junction proteins and blood pressure control, and the molecular structure of claudin-claudin interactions NOTE: Annals volumes are available for sale as individual books or as a journal.

This book was released on 2017-11-15 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great tunability of structure and electronic properties of ?-conjugated organic molecules/polymers combined with other advantages such as light weight and flexibility etc., have made organic-based electronics the focus of an exciting still-growing field of physics and chemistry for more than half a century. The application of organic electronics has led to the appearance of wide range of organic electronic devices mainly including organic light emitting diodes (OLED), organic field effect transistors (OFET) and organic solar cells (OSC). The application of the organic electronic devices mainly is limited by two dominant parameters, i.e., their performance and stability. Up to date, OLED has been successfully commercialized in the market while the OSC are still on the way to commercialization hindered by low efficiency and inferior stability. Understanding the energy levels of organic materials and energy level alignment of the devices is crucial to control the efficiency and stability of the OSC. In this thesis, energy levels measured by different methods are studied to explore their relationship with device properties, and the strategies on how to design efficient and stable OSC based on energy level diagrams are provided. Cyclic Voltammetry (CV) is a traditional and widely used method to probe the energy levels of organic materials, although there is little consensus on how to relate the oxidation/reduction potential ((Eox/Ered) to the vacuum level. Ultraviolet Photoelectron Spectroscopy (UPS) can be used to directly detect vertical ionization potential (IP) of organic materials. In this thesis, a linear relationship of IP and Eox was found, with a slope equal to unity. The relationship provides for easy conversion of values obtained by the two techniques, enabling complementarily use in designing and fabricating efficient and stable OSC. A popular rule of thumb is that the offset between the LUMO levels of donor and acceptor should be 0.3 eV, according to which a binary solar cell with the minimum voltage losses around 0.49 V was designed here. Introduction of the ternary blend as active layer is an efficient way to improve both efficiency and stability of the OSC. Based on our studied energy-level diagram within the integer charge transfer (ICT) model, we designed ternary solar cells with enhanced open circuit voltage for the first time and improved thermal stability compared to reference binary ones. The ternary solar cell with minimum voltage losses was developed by combining two donor materials with same ionization potential and positive ICT energy while featuring complementary optical absorption. Furthermore, the fullerene acceptor was chosen so that the energy of the positive ICT state of the two donor polymers is equal to the energy of negative ICT state of the fullerene, which can enhance dissociation of all polymer donor and fullerene acceptor excitons and suppress bimolecular and trap-assistant recombination. Rapid development of non-fullerene acceptors in the last two years affords more recipes of designing both efficient and stabile OSC. We show in this thesis how non-fullerene acceptors successfully can be used to design ternary solar cells with both enhanced efficiency and thermal stability. Besides improving the efficiency of the devices, understanding of the stability and degradation mechanism is another key issue. The degradation of conjugated molecules/polymers often follow many complicated pathways and at the same time many factors for degradation are coupled with each other. Therefore, the degradation of non-fullerene acceptors was investigated in darkness by photoelectron spectroscopy in this thesis with the in-situ method of controlling exposure of O2 and water vapor separately.
