Diffusion mechanism of water vapour in a zeolitic tuff rich in clinoptilolite
(Springer, 2008-12)
The adsorption kinetics of H2O in a clinoptilolite rich zeolitic tuff was experimentally investigated at 18°C. In the identification of the diffusion mechanism the isothermal adsorption model equation was used. It was found ...
The effect of zinc stearate on thermal degradation of paraffin wax
(Springer, 2008-12)
In this research, the effects of zinc stearate addition on paraffin wax degradation were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG). The apparent activation energies of wax decomposition ...
A study of chemical and physical changes during biaxially oriented polypropylene film production
(Walter de Gruyter, 2003)
Polypropylene films obtained during the biaxial orientation process were characterized by energy dispersive X-ray analysis (EDX), scanning electron microscopy. X-ray diffraction, differential scanning calorimetry, infrared ...
Adsorption characteristics of lead-, barium- and hydrogen-rich clinoptilolite mineral
(Multi-Science Publishing, 2003)
The carbon dioxide and water vapour adsorption properties of local clinoptilolite-rich material, both as the original and as lead-, barium- and hydrogen-rich forms, were examined. The lead- and barium-rich forms were ...
Dynamic heat of adsorption of water vapour on zeolitic tuff and zeolite 4A by flow microcalorimetry
(SCIBULCOM, 2006)
In this study a practical method for measurement of heat of adsorption of water vapour on adsorbents was developed to evaluate the feasibility of substitution of a zeolitic tuff with zeolite 4A in air drying and heat pumps. ...
Adsorption of olive leaf (Olea europaea L.) antioxidants on silk fibroin
(American Chemical Society, 2007-02)
The adsorption isotherms of oleuropein and rutin were evaluated at different temperatures, pH values, and solid/liquid ratios. The experimental data of adsorption isotherms were well fitted to a Langmuir model. The maximum ...
Effect of additives on flexible PVC foam formation
(Elsevier, 2008-01)
In this study, effects of Ca/Zn stearate and organotin heat stabilizers and zeolite, CaCO3, cellulose and luffa flours fillers, and their concentrations (2.5, 5, 10 and 20% by weight) on production of flexible PVC foams ...
Water and water vapor sorption studies in poly(propylene)-zeolite composites
(Wiley, 2003-10)
Water and water vapor sorption to porous poly(propylene)zeolite composites prepared by hot pressing have been studied as a function of zeolite loading. This work presents the first report on the effect of the zeolite as a ...
Thermal stability of Ag-exchanged clinoptilolite rich mineral
(Springer, 2008-12)
Thermal stability of clinoptilolite rich mineral from Western Anatolia, Turkey and its Ag-exchange forms was investigated. Parent mineral of different sizes were heated up to 1000°C with heating rate of 2 and 10°C min -1 ...
Cure kinetics of epoxy resin-natural zeolite composites
(Springer, 2008-12)
The cure kinetics of epoxy resin and epoxy resin containing 10 mass% of natural zeolite were investigated using differential scanning calorimetry (DSC). The conformity of the cure kinetic data of epoxy and epoxy-zeolite ...
