Recyclage des eaux usées en irrigation

Yeli Mariam Sou

The present study takes place in Ouagadougou (Burkina Faso), a typical Sub-Saharan city where water shortage and food crisis necessitate wastewater reuse in urban agriculture. Different issues linked to this practice were studied in two components separate ...

NMR, PGSE diffusion, and X-ray diffraction studies of lithium and potassium salts derived from diphenylphosphino(o-cyanophenyl)aniline and their crown ether complexes

Paul Joseph Dyson, Zhaofu Fei

H-1, P-31, and Li-7 pulsed-gradient spin-echo (PGSE) diffusion and variable-temperature NMR results for THF solutions of the lithium and potassium salts derived from diphenylphosphino(o-cyanophenyl)aniline are reported and compared to the solid-state resul ...

Synthesis and structural elucidation of a "free" phosphinoamide anion

Paul Joseph Dyson, Zhaofu Fei

The reaction of the aminophosphane C6H4(o-CN)NHPPh2 with elemental potassium in the presence of 18-crown-6 affords the phosphinoamide-containing complex [C6H4(o-CN)N-PPh2(THF)(18-Crown-6)K] which has been fully characterised in solution and the solid state ...

Typologie des eaux souterraines de la molasse entre Chambéry et Linz (France, Suisse, Allemagne, Autriche)

The geochemical typology of natural subsurface waters of the Molasse basin is part of the AQUITYP project, initiated by the Geology Laboratory (GEOLEP) of the Swiss Federal Institute of Technology in Lausanne (EPFL). This study provides an overview of the ...

cf. CA 50, 10030g. The stationary ligands on the P were varied in order to obtain an insight into the mechanism of the carbonyl-olefination with triphenylphosphylenes. The results demonstrated that the substitution of the Ph by p-MeC6H4, p-MeOC6H4, piperid ...
