the therrmodynamic parameters and equilibrium constant of displacement of dimethy sulfide by 3-carboaldehyde pyridine as n-donor ligand in cis-[pt(4-mec6h4)2(sme2)2] complex have been measured using uv vis spectroscopy in acetone, dichloromethane and benzene at various temperatures (t=15-20 °c) and compared with previous my reported about similar reaction. δho (kj.mol-1) of the mentioned reacti...

The aim of the present research is to convert bioinert surface of NiTi to bioactive and biocompatible surface. In order to develop a bioactive and corrosion resistant film on NiTi, electrophoretic deposition process was done and TiO2 particles were deposited on the NiTi surface. Suspensions including TiO2 particles were prepared using a mixture of acetone and n-butanol (0%, 30%, 60%, 80% and 10...

Plants extracts has been used in traditional medicine for many years. The use of them has the least side effects in comprison to the synthetic drugs. The aim of this study was investigation and comparision of biological active components of Quercus persica and Quercus ilex. Sampling was done from Quercus persica and Quercus ilex stands. The antibacterial activity was assayed against Psuodomonas...

seaweeds are the novel bioactive compounds resources with antioxidant activity. the aim of this study was to evaluate the efficacy of microwave radiation on antioxidant compounds extracted from red algae hypneahamulosa and optimal extraction conditions using response surface methodology (rsm).. independent variables were time (4,8,12 min), acetone/water concentration (50%,75% ,100% acetone) and...

Background and Aim: This study aimed to compare the effects of acetone and ethanolic extracts of Plantago major (P. major) on S. mutans.   Materials and Methods: In this in vitro study, the antibacterial effects of eight different concentrations of the acetone and ethanolic extracts of P. major seed were examined on S. mutans, and the minimum inhibitory concentration (MIC) and minimum bacte...

Background: Woodfordia fruticosa is used traditionally as antidysenteric compound for fodder animals. Stem and flower extracts are previously flourished for their antibacterial activity. Leaves are also equally important, which are preliminary screened for their bioactive components in present study. Objective: Evaluation of antibacterial activity of leaves of W. fruticosa and detection of the...
