Industrial applications of ionic liquids

The potential to use Ionic Liquids (ILs) as novel solvents or fluids for a diverse range of applications has become increasingly rent as researchers in academia and try respond to challenges from atmospheric emissions and disposal of many common solvents by evaluating novel reaction media. The intrinsic non-volatile nature of ILs provides an opportunity to reduce, or even completely eliminate, hazardous and toxic emissions to the atmosphere, thus providing the promise for significant environmental benefits. In synthesis and catalysis, ILs have been used as solvents (or solvents and catalysts), with the greatest current effort on using the ILs as alternatives to VOCs. In contrast, electrochemical studies hove utills'ed the fact that ILs are liquid rather than solids to provide liquid electrolytes without needing to odd an additional solvent. is overview appraiso an appraisal of potential to use ILs in industrial applications, illustrating some areas where practical uses are being developed, and how, throuqh understanding ionic liquids in a conceptuo level, new opportunities ore continuing to evolve.

Social psychology and peace: An introductory overview

This paper begins by giving an overview of why and in which ways social psychological research can be relevant to peace. Galtung's (1969) distinction between negative peace (the absence of direct violence) and positive peace (the absence of structural violence, or the presence of social justice) is crossed with a focus on factors that are detrimental (obstacles) to peace versus factors that are conducive to peace (catalysts), yielding a two-by-two classification of social psychological contributions to peace, Research falling into these four classes is cited in brief, with a particular focus on four exemplary topics: support for military interventions as an obstacle to negative peace; antiwar activism as a catalyst of negative peace; ideologies legitimizing social inequality as an obstacle to positive peace; and commitment to human rights as a catalyst of positive peace. Based on this conceptual framework, the remaining six articles of the special issue

Nature as historical protagonist: environment and society in pre-industrial England

This article compares chronologies reconstructed from historical records of prices, wages, grain harvests, and population with corresponding chronologies of growing conditions and climatic variations derived from dendrochronology and Greenland ice-cores. It demonstrates that in pre-industrial, and especially late medieval, England, short-term environmental shocks and more enduring shifts in environmental conditions (sometimes acting in concert with biological agencies) exercised a powerful influence upon the balance struck between population and available resources via their effects upon the reproduction, health and life expectancy of humans, crops, and livestock. Prevailing socio-economic conditions and institutions, in turn, shaped society's susceptibility to these environmental shocks and shifts.
