Vitrification of Thin Polymer Films: From Linear Chain to Soft Colloid-like Behavior
Macromolecules, 2015Co-Authors: Emmanouil Glynos, Bradley Frieberg, Alexandros Chremos, Georgios Sakellariou, David W. Gidley, Peter F. GreenAbstract:We show that the vitrification of Star-shaped polystyrene (PS), of functionality f and molecular weight per arm Mwarm, thin Films supported by silicon oxide, SiOx, is strongly dependent on Mwarm and f. When f is small, the vitrification behavior is similar to that of linear-chain PS where the average glass transition, Tg, decreases with decreasing Film thickness (ΔTg 0. We show that the overall vitrification behavior of these thin Film Star-shaped polymers is due to compet...

role of molecular architecture on the vitrification of polymer thin Films
Physical Review Letters, 2011Co-Authors: Emmanouil Glynos, Bradley Frieberg, David W. Gidley, Ming Liu, Peter F. GreenAbstract:We show that thin Film Star-shaped macromolecules exhibit significant differences in their average vitrification behavior, in both magnitude and thickness dependence, from their linear analogs. This behavior is dictated by a combination of their functionality and arm length. Additionally, the glass transition temperature at the free surface of a Star-shaped molecule Film may be higher than that of the interior, in contrast to their linear analogs where the opposite is true. These findings have implications for other properties, due largely to the origins, entropic, of this behavior.

From the Sacred to the Performative: Tamil Film Star Fan Clubs, Religious Devotion and the Material Culture of Film Star Portraits
The Journal of Religion and Popular Culture, 2011Co-Authors: Martyn RogersAbstract:Abstract: With the increasing blurring of the boundaries between the sacred realm of religion and the profane world of commerce, it is often argued that authentic religious faith is increasingly threatened by the forces of late capitalism. Using the example of Tamil Film spectatorship, the article argues otherwise. Drawing on Tamil Film fans' “devotional” practices dedicated to local Film Stars, the paper asserts that Tamil Film only remains relevant to its local audiences as long as consumption practices enable fans to subordinate the principles of commercial Film to locally embedded religious sentiments and dispositions, rather than vice versa.

between fantasy and reality tamil Film Star fan club networks and the political economy of Film fandom
South Asia-journal of South Asian Studies, 2009Co-Authors: Martyn RogersAbstract:Abstract Film permeates all spheres of Tamil Nadu social life extending into the domains of state governance and political discourse. Every chief minister since the 1960s and many prominent politicians, for instance, have previously been Film actors, directors or screen writers. Many Tamil politicians, therefore, use Film as a propaganda tool, as well as utilising their own fan club membership as potential election vote banks. Focusing on the fan club network of one prominent Tamil politician, the veteran actor Vijayakanth, the article investigates this link between politics and Film culture. It argues that social theorists analysing this social phenomenon focus too much attention on the propaganda function of Film texts rather than examining actual embodied social relationships within the interrelated arenas of Film culture and politics. Consequently, this focus overlooks fans’ political agency. Countering this perspective, the article argues that, in fact, Tamil Film Star fan clubs provide important soc...
