HNBR and its MWCNT reinforced nanocomposites : Crystalline morphology and electrical response
Morphology and electrical response of hydrogenated acrylonitrile butadiene rubber
(HNBR) and its multiwall carbon nanotube (MWCNT) reinforced nanocomposites
were studied by means of x-ray diffraction and broadband dielectric spectroscopy.
HNBR systems were found to be semi-crystalline, with their crystallinity to increase
with the addition of MWCNTs. In their dielectric spectra, four relaxation processes
were detected. Ascending in relaxation time, these were attributed to: (i) interfacial
polarization at the interface of crystalline and amorphous regions of HNBR and at the
interface between HNBR and MWCNTs, (ii) glass to rubber transition of the
amorphous part of HNBR, (iii) rearrangement of polar side groups, such as âCN, and
(iv) local motions of small segments of the main elastomer chain.
Electrical conductivity increases with MWCNT content and frequency increasing. The
effect of temperature, on the electrical response, is more pronounced at low frequencies. The temperature dependence of the electrical conductivity strongly deviates from a pure
Arrhenius behavior, signifying that the occurring conductance mechanisms do not
correspond to a single thermally activated process. Relaxation dynamics imply that
crystalline regions exert motion restrictions to large segments of the macromolecules
in the amorphous phase and to polar parts of the systems
Alternative organizing in times of crisis : resistance assemblages and socio-spatial solidarity
This paper draws on research conducted in Greece, where, during the last seven years, an acute socio-economic crisis has led to the emergence of a number of alternative organizational forms. By foregrounding the term drasis, the unexpected unfolding of an event in a specific space and time, we discuss how these alternative forms assemble differential capacities in order to resist the neoliberal ordering of socio-spatial and economic relations. In particular, we focus on two self-organized spaces, namely, a social centre and a squatted public garden and discuss two concrete instances of drasis. We propose that drasis instigates the establishment and evolution of transformative, prefigurative organizing through three interrelated processes, namely, the formation of resistance assemblages, social learning and socio-spatial solidarity. The paper offers three propositions, suggesting that drasis provides the socio-material conditions through which new resistance formations challenge the established productive forces of society and co-produce alternative forms of civic life.© 2017 published by SAGE.

Revolt and crisis in Greece: Between a Present Yet to Pass and a Future Still to Come
How does a revolt come about and what does it leave behind? What impact does it have on those who participate in it and those who simply watch it? Is the Greek revolt of December 2008 confined to the shores of the Mediterranean, or are there lessons we can bring to bear on social action around the globe? Revolt and Crisis in Greece: Between a Present Yet to Pass and a Future Still to Come is a collective attempt to grapple with these questions
The EC hotspot approach in Greece: creating liminal EU territory
This article makes a theoretical argument stemming from our study of the European Commissionâs hotspot approach to the management of migrant populations. It draws on empirical research findings from field research which took place on the island of Lesbos and in the city of Athens over the course of 20 months and links these to emerging critical studies of the new EU border regime. No clear definition exists of what comprises a hotspot: instead, the European Commission describes this as an integrated âapproachâ for the enhancement of the capacity of member states to deal with crises resulting from pressures at the Unionâs external borders. Effective in its ambiguity, the âhotspot approachâ therefore constitutes, as we argue, an integral part of the Europeanisation and institutionalisation of border management: a powerfully ambiguous dispositif in the EUâs emerging border regime. The article unpacks the notion of the hotspot from a historical perspective and explores the ways in which the hotspot contributes toward the culmination of European integration, paving the way for the flexible governance of mobility and asylum. We situate the hotspot within the historical shift of migration and mobility control from the border to the territory as a whole and conclude by arguing that the hotspot plays the role of a territorial incubator for the liminal EU territory: a paradigmatic space for a new form of governance that further disentangles territory from rights
Flags Flying up a Trial Mast:Reflections on the Hotspot Mechanism in Mytilene
In one sense the hotspot is, then, already here: it lies in the reception centres, the detention centres, the temporary camps, the mechanisms of registration, filtering, hosting and relocating the people arriving in the EU. But in another sense, the hotspot is a future excess of the sum of all those parts: a glimpse into the all-encompassing population filtering apparatus yet to come
