Complexos carbonílicos de rutênio. De um gás tóxico a uma droga com potencial agente citotóxico
(Universidade Federal de São Carlos, 2007-11-27)
In this work ruthenium carbonyl complexes were synthesized and characterized which allowed an interesting spectroscopic and structural study as well as preliminary in vitro antitumor activity assays. Thus, the interests ...
Titulações potenciométricas de cátions metálicos tendo como eletrodo indicador o sistema Cu/CuY2-
(Universidade Federal de São Carlos, 2007-07-27)
In this work a Cu/CuY2- indicator system was used to carry out potentiometric titrations of Cu2+, Co2+, Cd2+, Zn2+ and Mn2+ ions with EDTA solution. A copper wire with 8.32 cm2 of superficial area was used as an indicator ...
Estudo teórico do espalhamento de elétrons por radicais livres
(Universidade Federal de São Carlos, 2007-07-13)
In this present work, we have carried out some calculations of electron-radicals scattering cross sections in the lowjintermediate energy range. Differential, integral, momentum transfer, total and total of absorption cross ...
Estudos físico-químicos do efluente produzido por fossa séptica biodigestora e o impacto do seu uso no solo
(Universidade Federal de São Carlos, 2007-08-01)
The generation of effluent from the sewage treatment is daily increasing then its final disposition represents a mandatory question to be answered. An alternative is its agricultural utilization such as organic fertilizer ...
