Facile in situ synthesis of nanofluids based on ionic liquids and copper oxide clusters and nanoparticles

Two stable nanofluids comprising of mixed valent copper(_I,_II) oxide clusters (<1 nm) suspended in 1-butyl-3-methylimidazolium acetate, [C(₄)mim][OAc], and copper(_II) oxide nanoparticles (<50 nm) suspended in trioctyl(dodecyl) phosphonium acetate, [P-₈₈₈₁₂][OAc], were synthesised in a facile one-pot reaction from solutions of copper(_II) acetate hydrate in the corresponding ionic liquids. Formation of the nanostructures was studied using ¹³C NMR spectroscopy and differential scanning calorimetry (DSC). From a solution of Cu(OAc)₂ in 1-ethyl-3-methylimidazolium acetate, [C₂mim][OAc], crystals were obtained that revealed the structure of [C₂mim][Cu₃(OAc)₅(OH)₂(H₂O)]center dot H₂O, indicating the formation of copper hydroxo-clusters in the course of the reaction. Synthesised nanostructures were studied using transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). Physical properties of the prepared IL-nanofluids were examined using IR and UV-VIS spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and densitometry.

Touching at a Distance: Resistance, Tactility, Proxemics and the Development of a Hybrid Virtual/Physical Performance System

This is a paper about resistance and affordance as they relate to music-making in the most extended sense, and perhaps about empathy if this is understood as a capacity to ‘read’ the resistances and affordances of objects, bodies, people and environments. It proceeds from a set of broad working assumptions which inform one individual’s musical practice, via a description a musical-instrument making project which is a hybrid of physical and virtual elements and is designed to test those assumptions, to a speculative finale in which it is suggested that musicking might, in some circumstances, be regarded in itself as a form of resistance. It moves from the intimate and personal, through what might be regarded as local concerns to more global observation, prefiguring the structure of the performance system it describes: the Virtual-Physical Feedback flute

Direct Democracy and Regional Integration::Citizens' Perceptions of Treaty Implications and the Irish Reversal on Lisbon

Analyses of voting in European Union referendums typically distinguish between ‘second-order’ effects and the impact of substantive ‘issues’. In order to explain change in referendum outcome, two types of substantive issues are distinguished in this article. Focusing on Irish voting in the Lisbon Treaty referendums and using data from post-referendum surveys, it is found that perceptions of treaty implications outperform underlying attitudes to EU integration in predicting vote choice at both referendums, and perceptions of treaty implications are strong predictors of vote change between the referendums. The findings have broadly positive implications for normative assessments of the usefulness of direct democracy as a tool for legitimising regional integration advance.

Qualitative research on chronic illness:A commentary on method and conceptual development

This concluding essay discusses some crucial methodological issues raised by other papers in this issue. It also suggests directions for further conceptuel development concerning the qualitative research on chronic illness.
