Sulfonated poly(ether ether ketone)/clay-SO3H hybrid proton exchange membranes for direct methanol fuel cells Journal of Power Sources

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.

Geomorphic and hydrodynamic responses in salt marsh-tidal creek systems, Jiangsu, China

Salt marsh-tidal creek systems as a coastal geomorphological unit represent an important natural resource. The present study on Jiangsu salt marshes, eastern China, shows that variations in tidal current velocities in salt marsh creeks are controlled by the local tidal wave characteristics and the bed slope and elevation of the salt marshes and creeks. Likewise, the tidal currents modify the geomorphology of the salt marsh-tidal creek systems by transporting sediments and causing erosion/deposition. Storm events, which appear to have cyclical changes in their intensity relating to sunspot activities, can affect the geomorphic evolution of such systems. Further, in response to accelerated sea-level rise, accretional rates on salt marshes may increase. The tidal creeks have the function of transporting water and sediment onto the salt marsh surface; further, the energy of tidal currents and waves are dissipated within the salt marsh-tidal creek system. Hence, this coastal system has a potential value for coastal protection.

Journeying to a journal

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.
