Dialogical Skirmishes
No full textTan was guest editor for 'And Now China?', a special print edition of the Ctrl+P journal, which critically responded to the celebratory rhetoric’s of ‘China Now’ and other celebratory markers of China's global ascent in 2008. As well as the introductory article 'Dialogical Skirmishes', Tan also interviewed Hans Ulrich Obrist

Preparation and characterization of PEO-PMMA-LiCIO[4]-EC-MnO[2] nanocomposite polymer electrolytes / Tan Say Min
No full textPolymer electrolytes are of great interest for solid-state-electrochemical devices
especially in fuel cells and battery. There have been many studies that carried out to
improve the ionic conductivity in polymer electrolytes which include polymer blending,
incorporating plasticizers and filler additives in the electrolytes system. This thesis
describes the combined effect of incorporating the nano-sized MnO2 filler and the
EC plasticizer on the ionic conductivity enhancement of the polymer blend PMMAPEO-
LiClO4 electrolyte. Maximum conductivity has been achieved by optimizing the
compositions of the plasticizer and the filler. Conduction characteristics of the
polymer electrolyte system are investigated. Free standing flexible electrolyte films of
composition 13.68 wt% PEO, 54.72 wt% PMMA, 7.59 wt% LiClO4, 19 wt% EC and 5
wt% MnO2 are prepared by solution casting method. A combination of X-ray diffraction
(XRD), UV-Vis spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, Field
Emission Scanning Electron Microscopy (FESEM), thermal gravimetric analysis (TGA)
and differential scanning calorimetry (DSC) studies have indicated enhancement in the
amorphous phase of polymer system due to the polymer blend, plasticizer addition and
filler addition. Further, a reduction in the glass transition temperature and optical band
gap has inferred increase in the flexibility of the polymer chains. Ionic conductivity
studies are carried out as a function of chemical composition and temperature using
impedance spectroscopy. The conductivity values are presented and results are
discussed
Free thinking - running
No full textWe've been running for two million years give or take. Shahidha Bari and Laurence Scott explore contemporary running as solitary inspiration and communal activity with the Geographer and 1999 Scottish Hill Running Champion, Hayden Lorimer, the artists Kai Syng Tan and Angus Farquhar, and the literary scholar and bare-foot artiste, Vybarr Cregan-Reid. Conversation ranges from feeling empowered on city streets to teaming up with the wind to the horrid history of the treadmill and explore whether Running deserves better representation in the arts. Guests: Vybarr Cregan-Reid - author of Footnotes How Running Makes Us Human Angus Farquhar, Creative Director of NVA Public Art, author of a blog 'The Grim Runner' Hayden Lorimer Running Geographer Kai Syng Tan, Artist and curator of a biennial festival Run Run Run Producer: Jacqueline Smith
