Clinoptilolite, a natural zeolitic tuff, was used as the filling material into the composites. Effect of both pure clinoptilolite and silver ion exchanged form of clinoptilolite addition on the thermal degradation kinetics of polypropylene composites was studied by using differential scanning calorimetry (DSC) and thermal gravimetry analysis (TGA) techniques. Polymer degradation was evaluated by using DSC with heating rates of 5, 10, and 20 degrees C/ min from room temperature up to 500 degrees C. Silver concentration (4.36, 27.85 and 183.8 mg Ag/g zeolite) was the selected parameter under consideration. From the DSC curves, it was observed that the heat of degradation values of the composites containing 2-6% silver exchanged zeolites (321-390 kJ/kg) were larger compared to that of the pure PP free of silver and zeolite (258 kJ/kg). From the DSC results it was confirmed that PP-zeolite composites can be used at higher temperatures compared to the pure PP polymer because of its higher thermal stability. The thermal decomposition activation energies of the composites were calculated by using both the Kissenger and Ozawa models. The values predicted from these two equations were in close agreement. From the TGA curves, it was found that zeolite addition into the PP matrix speeds down the decomposition reaction, however, silver exchanged zeolite addition into the matrix accelerates the reaction. The higher the silver concentration, the lower the thermal decomposition activation energies were obtained. As a result, PP was found to be much more susceptible to thermal decomposition in the presence of silver exchanged zeolite.Article Citation - WoS: 12Regional Acupuncture for İzmir Peninsula: Creating Capital Web for Creative Eco-Tourism(Scibulcom Ltd., 2016) Velibeyoğlu, KorayRural socio-economic development has gained utmost importance in Turkish Metropolitan Municipalities within the frame of recent legal changes extending the boundary of such municipalities towards their larger rural hinterland. Beforehand, Izmir Metropolitan Municipality had been started 'Izmir Peninsula Sustainable Development Strategy' in 2013 as a model of their local development agenda based on the principles of 'Urla-Cesme-Karaburun Peninsula Local Development Idea Competition' held in 2008. Izmir Peninsula region is the nature reserve for Izmir with its specific flora and fauna always considered as perfect location for eco-tourism activities. This paper aims to illustrate the development and implementation mechanisms of creative eco-tourism strategies for the region with concrete examples including thematic tourism routes based on green transportation, local production and consumption networks (i.e. local bazaars, family pensions) and special events aim to create local buzz and global pipelines. The major contribution of this study is to illustrate a model of networked integration strategy by using 'creative' eco-tourism opportunities of Izmir Peninsula Region. It exemplifies the key implementation mechanisms of regional acupuncture and capital web approach derived from the idea of network of local micro-projects working in synergy.
