A new type of sulfonated clay (clay-SO3H) was prepared by the ion exchange method with the sulfanilic acid as the surfactant agent. The grafted amount of sulfanilic acid in clay-SO3H was 51.8 mequiv. (100 g)(-1), which was measured by thermogravimetric analysis (TGA). Sulfonated poly(ether ether ketone) (SPEEK)/clay-SO3H hybrid membranes which composed of SPEEK and different weight contents of clay-SO3H, were prepared by a solution casting and evaporation method. For comparison, the SPEEK/clay hybrid membranes were produced with the same method.

At a Council meeting of the newly-formed Cork Historical and Archaeological Society, 17 November 1891, the Chairman /President, Revd R.A. Canon Sheehan, 'informed the meeting that Mr. Robert Day had been generous enough to place his valuable edition of Smith's History, with notes by Dr. Caulfield and Crofton Croker, at the disposal of the Society for publication'. At a subsequent meeting Wm Ringrose Atkins expressed the Society's thanks to W.A. Copinger 'who has kindly consented to edit Smith's Cork with Mr. Robert Day'. Thus began the work of rounding out close to two and a half centuries of antiquarian endeavour in Cork and of using its synthesis as a foundation for a new medium to record and communicate the social and cultural heritage of Cork city and county.
