Green Chemistry is placed in the frontier areas of research and has been focused for considerable recent research. Green Chemistry, the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances is an overarching approach that is applicable to all aspects of chemistry. From feedstocks to solvents, to synthesis and processing green chemistry...

This review discusses the analytical characterization of molecular electronic devices and structures relevant thereto. In particular, we outline the methods for probing molecular junctions, which contain an ensemble of molecules between two contacts. We discuss the analytical methods that aid in the fabrication and characterization of molecular junctions, beginning with the confirmation of the ...

Countercurrent chromatography (CCC) is a generic term covering all forms of liquid–liquid chromatography that use a support-free liquid stationary phase held in place by a simple centrifugal or complex centrifugal force field. Biphasic liquid systems are used with one liquid phase being the stationary phase and the other being the mobile phase. Although initiated almost 30 years ago, CCC lacked...

Current environmental concerns are pressuring Chemical and Pharmaceutical industries to develop novel synthetic approaches that may operate under more benign conditions. This trend has paramounted the appearance of the “Green Chemistry” as a core discipline, with an increasing importance both in academia and industry. In a nutshell, Green Chemistry—as well as Green Engineering—has been compiled...

The connection between astrobiology and green chemistry represents a new approach to sustainability of organic matter on asteroids or similar bodies. Green chemistry is chemistry which is environmentally friendly. One obvious way for chemistry to be green is to use water as a solvent, instead of more toxic organic solvents. Many astrobiological reactions occur in the aqueous medium, for example...

This focused collection of papers is devoted to recent developments in ‘green chemistry’, especially the applications of catalytic methods, involving both chemoand biocatalysis. The development of catalytic processes is an important current theme in organic chemistry, since it aims to reduce the environmental impact of the industrial synthesis of chemicals and polymers by replacing stoichiometr...
