Nano-Ag particles loaded on TiO 2 (Ag-TiO 2 ) were used as catalyst for the UV-induced cold vapour generation with formic acid coupled to atomic absorption for determination of

Preliminary experiments showed that the immobilized catalyst could be used in at least three consecutive Suzuki reactions with the same catalytic activity.. Keywords

The objective of this study was to carry out a multivariate optimization of PSE considering the variables temperature, solvent and extraction time, which affect APEOs and APs

The better distinction between RB5453 and RB5054 in NMR analyses in solution was justified considering the fact that the extraction procedure highlighted the differences about

The efficient approach and rapid synthetic route reported here should be easily applied to the synthesis of analogues for further biological testing, which will be reported in

In this strategy, substituted anti 2-amino-1,3-propanediols were readily prepared via ozonolysis of allylic diols obtained from MBH adducts, followed by a

To explain the low matrix effect of the organophosphate pesticide, the possibility of pyrethroid (specifically Figure 4. Ratio between slope coefficients and ratio between intercept

The structures of all compounds were determined by spectrometric methods such as 1D and 2D NMR (COSY, HSQC and HMBC) and HREISMS beside comparison with spectral data for
