Substrate-induced coagulation (SIC) is a coating process based on self-assembly for coating different surfaces with fine particulate materials. The particles are dispersed in a suitable solvent and the stability of the dispersion is adjusted by additives. When a surface, pre-treated with a flocculant e.g. a polyelectrolyte, is dipped into the dispersion, it induces coagulation resulting in the deposition of the particles on the surface. A non-aqueous SIC process for carbon coating is presented, which can be performed in polar, aprotic solvents such as N-Methyl-2- pyrrolidinone (NMP). Polyvinylalcohol (PVA) is used to condition the surface of substrates such as mica, copperfoil, silicon-wafers and lithiumcobalt oxide powder, a cathode material used for Li-ion batteries. The subsequent SIC carbon coating produces uniform layers on the substrates and causes the conductivity of lithiumcobalt oxide to increase drastically, while retaining a high percentage of active battery material.

Where the speed-up of technology led Marshall McLuhan into the realm of ‘pattern-recognition’ the game has now been ratcheted up a further notch. Technologies themselves are being creatively re-designed and reconfigured to hunt down the Snark (see Lewis Carrol, 1898), a game in which the skill of identifying gaps, ruptures, of cracking the surface, remains critical. In this situation a New Minimalism has taken shape in which narrative and content have not been erased exactly but have retreated, to be resident in the architecture and flow of the apparatus itself. For Marcia Jane this is where the story now sits, to be laid bare on the Gallery floor.

This article explores insurability relating to loss occasioned by catastrophic events in Australia in the context of the current legal regulatory regime. The analysis includes two case studies, in which we juxtapose the Victorian Black Saturday fires in February 2--9 with the Queensland flooding and Cyclone Yasi (December 2010 - February 2011). We argue that the different responses to, and economic losses stemming from, these events illustrate the urgent need for a national regulatory and insurance regime for the prevention and alleviation of disasters and the management of their consequences.
