The oxidative desulfurization reactions were performed in order to obtain the conversion of thiophene to sulfone as function of the reaction time present in a n-heptane solution at

Moreover, we compared the effects of two different dehydration techniques applied to the coprecipitated gels to provide nanocrystalline powders with high speciic surface area

The addition of organoclay illers results in slower polymerization rates (0.59 and 0.24 mol L -1 min -1 , for the formulations without and with 15% of organoclay, respectively)

These two effects, increase of electrical conductivity due to charge carrier concentration and decrease due to a blocking secondary phase at grain boundaries, must be balanced

A higher oxidation temperature, such as 600 °C used in this study, produces an oxide layer composed of large Cu 2 O crystals.. The grain boundary paths are limited to the layer

A comparison (PHB thermo-compression molded ilm versus nanoibers mat) of the mechanical properties in tensile mode is shown in Figure 9.. The values related to PHB

The modulus decrease was progressive with ageing time, which probably occurred because of the strong chemical interaction of the PA-11 with anhydrous and hydrated ethanol,
