Resumo O silicato de cálcio hidratado (C-S-H), principal fase proveniente da hidratação do cimento Portland, tem grande influência na maioria das propriedades físicas e mecânicas dos materiais cimentícios. No entanto, até o momento, não existem modelos estruturais relacionando sua composição química, nano e microestrutura com suas propriedades físi...
The subject of this thesis covers the synthesis and growth of indium, tin and zinc oxide nanostructures by thermal evaporation and hydrothermal synthesis and the fabrication and testing of gas sensors and ultraviolet photodetectors based on these nanosized structures. For both chemical and physical routes, the influence of processing conditions ove...
