1. X-ray photoinduced effects in glassy films of CuO doped [Sb(PO3)3]n-Sb2O3 system / Estudo dos efeitos fotoinduzidos por Raio-X em filmes vítreos do sistema [Sb(PO3)3]n-Sb2O3 dopados com CuO
The photosensibility to radiation of phosphate glasses is a property that has attracted great interest in the last decades12. In this work, we realized a systematic and comparative study of the photoinduced phenomena through characterization of the doped copper oxide (CuO) (Sb(PO3)3)n-Sb2O3 system films. In this study, we observed the photostructural changes

2. Síntese de derivados do fulereno-C60
Presently, C60 fullerene and its derivatives are of great importance in chemistry, mainly due to their physical properties and biological activities. One of the main problems related to C60 is its low solubility in the commonly used solvents, which limits its application. Aiming to study their physicochemical properties, 17 new C60 derivatives with appropria

3. Processos redoxes de ferro em argilominerais: caracterização, métodos de quantificação, especiação e modificações estruturais
Redox processes within clays and clay minerals influence significantly in different physical and chemical properties in soils and sediments, mainly which ones related to the chemical interaction between solid and solution phases (liquid or gas) such as superficial charge and ion dynamics. Other, like expansibility, water retention capacity, surface area, and

4. "Estudos espectroscópicos e citotóxicos do Photogem® fotodegradado e dos fotoprodutos formados pela irradiação com laser" / "Spectroscopics and cytotoxics studies of Photogem® photodegradate and of photoproducts formated by irradiation with laser"
Photodynamic therapy (PDT) is a technique for inducing tumor tissue damage following administration of a drug that can be selectively retained in malignant tissue and produce singlet oxygen when irradiated in adequate wavelengths in the presence of molecular oxygen. Photosensitizers of porphyrin type can be degraded by light (photobleaching), modifying the c
