This manuscript describes the reductive removal of silyl groups from N-protected indoles, using indium, magnesium, zinc and fer processes and new method for synthesis an N-tertButanesulfinylimines. In the main part: ...

Samples of pure zinc aluminates (ZnAl2O4) and doped ZnAl2O4 with both lead (Pb2+) at different ratios (0, 0.5, 1, 1.5, 2, and 2.5% mol) and a constant amount of lanthanum (La3+: 1% mol), were prepared by the citrate ...

This work is a contribution to the quantification and simulation of primary recrystallization in IF steels. IF steels are alloys with high drawing capacity and are intended for the automotive industry. To do this, we ...

Water erosion presents a natural risk those results primarily from the fragility of the environment and the anarchic socialization of the slopes. Currently, it is the leading cause of degradation of water resources. It ...

Nicotiana glauca Graham (Solanaceae), or tree tobacco, is found in dry arid climates of North America, Africa and Europe. It has been reported to have both toxic and medicinal properties. The main aim of this study was ...

Here, an Ambrosia maritima and Bituminaria bituminosa were assessed for their phenolic profile composition, their potential antioxidant activity in vitro, and their cytoprotective effect in primary cultured human umbilical ...

In this work, an experimental study and analysis of the effects of environmental relative humidity (RH %) on the transport mechanisms of electrical charges in PI films have been presented. The evolution of the surface ...

The planet's natural resources have been overexploited in order to handle the growing human population, leading to significant loss of biodiversity, climate change and disruption of the nitrogen cycle. Since then, the ...
