It was demonstrated that the present hyphenated technique, using a continuous mode hydride generation gas phase in situ trapping on an integrated silica tubes trap, followed

Synthesis of Novel PETT Analogues: 3,4-Dimethoxy Phenyl Ethyl 1,3,5-Triazinyl Thiourea Derivatives and their Antibacterial and Anti-HIV Studies..

by an interface reaction producing a partially reduced perovskite LaMnO 3- δ and highly dispersed iron oxides, mainly Fe 3 O 4 , on the Fe o surface. These results can be discussed

For pure PVK the emission is centered at 375 nm, and for pure Eu(tta) 3 bipy at 613 nm, and the results of Figure 5 show that in solution, all the blends present incomplete..

The method has been successfully applied to the determination of carbofuran in rice, wheat and various environmental and biological samples.. The results obtained were compared

The initial concentration (08:00 am) used in the simulation were 0.70 and 0.03 ppm for CO and NO x , respectively, the mean experimental values obtained by the automatic

As it is obvious from these figures, among the lanthanide ions tested, Er(III), with the most Nerstian response, can be suitably determined with the PVC membrane sensor based on

This behavior can be interpreted on the bases of this fact that by increasing of dyes concentration in the presence of CPC surfactant, self aggregation of dyes affected binding
