Book Description
In his Master project Sven Herrmann for the first time carried out fundamental investigations into the development of polyoxometalate based ionic liquids (POM-ILs). The POM-ILs were obtained by charge balancing inorganic polyoxometalate (POM) anions with sterically demanding tetraalkylammonium or tetraalkylphosphonium cations. By functionalization of lacunary Keggin clusters with 3d-transition metals and charge balancing with tetraalkylammonium cations of differing chain length, a model system for the correlation of the molecular structure with macroscopic materials properties was obtained. In a systematic approach the syntheses via self-aggregation is presented. Analytic methods comprise UV-Vis, FTIR, NMR, EPR and Mößbauer spectroscopy. For determination of the materials properties TGA and DSC were carried out and rheological studies shed light onto the flow characteristics of the highly viscous materials. Contents Polyoxometlates and Ionic Liquids in General POM-Ils as New Class of Compounds Synthesis and Characterization of POM-ILs Reactivity Towards Azide and Carbonmonoxide Target Groups Researchers and students in the field of chemistry Practitioners in this area The Author Sven Herrmann obtained his Masters degree at the University of Erlangen-Nürnberg. He then joined the working group of Prof. Carsten Streb in the inorganic department at the University of Ulm to work on his PhD thesis that targets the development of polyoxometalate based ionic liquids (POM-ILs).

Book Description
Well-researched reference on stable alternative electrocatalysts and electrode materials with the potential to transform chemistry and processes in sensor- and energy-related technologies Applied Polyoxometalate-based Electrocatalysis delivers an overview of the variety of efficient applications of free POM and POM-based (nano)composites as exciting materials in the field of electrocatalysis. With a variety of sizes, shapes, composition, and physical and chemical properties, these composites have important properties, such as the ability to undergo reversible multivalence reductions/oxidations, leading to the formation of mixed-valence species, which brings about favorable electrocatalytic properties with regard to several electrochemical processes. Edited by a highly qualified independent researcher internationally recognized for her contributions to materials for electrochemical energy-related reactions, Applied Polyoxometalate-based Electrocatalysis includes information on: General methodologies used in the preparation of free POMs and POM-based nanocomposites and different strategies employed in electrode modification Role of POM-modified electrodes in oxidative and reductive electrocatalysis, including the detection/sensing of several (bio)molecules of interest and carbon dioxide electroreduction Application of POM-based (nano)composites, including the oxygen reduction reaction relevant to fuel cells, the oxygen and hydrogen evolution reactions, and batteries and supercapacitors Applied Polyoxometalate-based Electrocatalysis is an essential reference on the subject for chemists, material scientists, chemical engineers, and institutions involved in work related to free POM and POM-based (nano)composites.

Book Description
Combined oxygen, in the form of water, metal oxides, silicates and other oxyions, accounts for about 50% by weight of the earth's crust. The chemistry of this most abundant element has two major aspects: that of water and aqueous solutions of electrolytes, and that of the solid state. The methodology and techniques appropriate for the study of these fields are sufficiently different that there have been very few points of contact between solution- and solid state chemists. One such contact, of great potential value, is provided by the extensive class of polyoxoanions formed by the transition metals of groups 5 and 6. As 'heteropoly and isopoly acids' these polyanions have been known and investigated for more than a century. The pre sent book is an attempt to survey the chemistry, structures, and applications of these species. Although the book forms part of a series in inorganic chemistry, the field of polyoxometalates deserves wider attention, for example, from organic chemists, especially those concerned with homogeneous and heterogeneous catalysis, and from biochemists, solid state- and materials scientists.

Book Description
This volume contains a series of papers originally presented at the symposium on Water Soluble Polymers: Solution Properties and Applications, sponsored by the Division of Colloids and Surface Chemistry of the American Chemical Society. The symposium took place in Las Vegas City, Nevada on 9 to 11th September, 1997 at the 214th American Chemical Society National Meeting. Recognized experts in their - spective fields were invited to speak. There was a strong attendance from academia, g- ernment, and industrial research centers. The purpose of the symposium was to present and discuss recent developments in the solution properties of water soluble polymers and their applications in aqueous systems. Water soluble polymers find applications in a number of fields of which the following may be worth mentioning: cosmetics, detergent, oral care, industrial water treatment, g- thermal, wastewater treatment, water purification and reuse, pulp and paper production, sugar refining, and many more. Moreover, water soluble polymers play vital role in the oil industry, especially in enhanced oil recovery. Water soluble polymers are also used in ag- culture and controlled release pharmaceutical applications. Therefore, a fundamental kno- edge of solution properties of these polymers is essential for most industrial scientists. An understanding of the basic phenomena involved in the application of these polymers, such as adsorption and interaction with different substrates (i. e. , tooth enamel, hair, reverse - mosis membrane, heat exchanger surfaces, etc. ) is of vital importance in developing high performance formulations for achieving optimum efficiency of the system.

Book Description
This book summarizes the latest knowledge in the science and technology of ionic liquids and polymers in different areas. Ionic liquids (IL) are actively being investigated in polymer science and technology for a number of different applications. In the first part of the book the authors present the particular properties of ionic liquids as speciality solvents. The state-of-the art in the use of ionic liquids in polymer synthesis and modification reactions including polymer recycling is outlined. The second part focuses on the use of ionic liquids as speciality additives such as plasticizers or antistatic agents. The third part examines the use of ionic liquids in the design of functional polymers (usually called polymeric ionic liquids (PIL) or poly(ionic liquids)). Many important applications in diverse scientific and industrial areas rely on these polymers, like polymer electrolytes in electrochemical devices, building blocks in materials science, nanocomposites, gas membranes, innovative anion sensitive materials, smart surfaces, and a countless set range of emerging applications in different fields such as energy, optoelectronics, analytical chemistry, biotechnology, nanomedicine or catalysis.
