Recently, an important scientific event in metathesis chemistry, the NATO-Advanced Study Institute New Frontiers in Metathesis Chemistry: From Nanostructure Design to Sustainable Technologies for . Synthesis of Advanced Materials was organized in Antalya, Turkey (September 4-16, 2006). Prominent scientists, young researchers and students, convened for two weeks to debate on the newest trends in olefin metathesis and identify future perspectives in this fascinating field of synthetic organic, organometallic and polymer chemistry with diverse potential applications in materials science and technology. Following the fruitful practice of the previous NATO ASI meetings, selected contributions comprising plenary lectures, short communications and posters are compiled in this special volume dedicated to this outstanding international scientific meeting. Olefin metathesis, one of the most efficient transition metal mediated C-C forming reactions, awarded in 2005 with the Nobel Prize for chemistry to Yves Chauvin (IFP), Robert H. Grubbs (Caltech) and Richard R. Schrock (MIT), asserted itself during the last decade as a powerful synthetic strategy for obtaining fine chemicals, biologically active compounds, architecturally complex assemblies, new materials and functionalized polymers tailored for specific utilizations (e.g. sensors, semiconductors, microelectronic devices) etc. Metathesis reactions such as ring-closing metathesis (RCM), enyne metathesis, cross-metathesis (CM), acyclic diene metathesis polymerizafion (ADMET) and ring-opening metathesis polymerization (ROMP), largely dealt with during the ASI meeting, have gone far beyond the 20-th century boundaries resulting in a broad diversification towards sustainable technologies with perspectives for industrial applications of a wide range of products, from the manufacture of smart, nanostructured materials to the synthesis of complex organic compounds, natural products, pharmaceuticals and supramolecular assemblies.

An outstanding international scientific event in the field of metathesis chemistry, the NATO ASI "Green Metathesis Chemistry: Great Challenges in Synthesis, Catalysis and Nanotechnology" has been recently organized in Bucharest, Romania (July 21- August 2, 2008). Numerous renowned scientists, young researchers and students, convened for two weeks to present and debate on the newest trends in alkene metathesis and identify future perspectives in this fascinating area of organic, organometallic, catalysis and polymer chemistry with foreseen important applications in materials science and technology. Following the fruitful practice of NATO Advanced Study Institutes, selected contributions covering plenary lectures, short communications and posters have been compiled in this special volume dedicated to this successful convention on green metathesis chemistry. General interest was primarily focused on relevant "green chemistry" features related to all types of metathesis reactions (RCM, CM, enyne metathesis, ADMET and ROMP). Diverse opportunities for green and sustainable technologies and industrial procedures based on metahesis have been identified. Largely exemplified was the utility of this broadly applicable strategy in organic synthesis, for accessing natural products and pharmaceuticals, and also its ability to fit in the manufacture of smart and nanostructured materials, self-assemblies with nanoscale morphologies, macromolecular engineering.

Electromembrane processes offer a multitude of applications, allowing for the recovery of water, other products, and energy. This book is a collection of contributions on recent advancements in electromembrane processes attained via experiments and/or models. The first paper is a comprehensive review article on the applications of electrodialysis for wastewater treatment, highlighting current status, technical challenges, and key points for future perspectives. The second paper focuses on ZSM-5 zeolite/PVA mixed matrix CEMs with high monovalent permselectivity for recovering either acid or Li+. The third paper regards direct numerical simulations of electroconvection in an electrodialysis dilute channel with forced flow under potentiodynamic and galvanodynamic regimes. The fourth paper investigates the reasons for the formation and properties of soliton-like charge waves in overlimiting conditions. The fifth paper focuses on the characterization of AEMs functionalized by surface modification via poly(acrylic) acid yielding monovalent permselectivity for reverse electrodialysis. In the sixth paper, CFD simulations of reverse electrodialysis systems are performed. The seventh paper proposes an integrated membrane process, including electrochemical intercalation–deintercalation, for the preparation of Li2CO3 from brine with a high Mg2+/Li+ mass ratio. Finally, the eighth paper is a perspective article devoted to the acid–base flow battery with monopolar and bipolar membranes.

Homogeneous catalysis owes its success, in large part, to the development of a wide range of ligands with well-defined electronic and steric properties, which have thus made it possible to adjust the behavior of many organometallic complexes. However, ligands used in catalysis have long been centered on elements of group 15, and it is only more recently that carbon ligands have proved to be valuable alternatives with the emergence of cyclic diaminocarbenes (NHC).This Special Issue aims to provide a contemporary overview of the advances in carbon ligand chemistry from fundamental aspects to applications.
