Characterization of flavonoids in the ethyl acetate extract from Euphorbia hirta L. by liquid chromatography and tandem mass spectrometry
4. Karanga Yssouf, Ilboudo Ousmane, Tapsoba Issa, Colson Emmanuel, Gerbaux Pascal, Bonzi-Coulibaly Yvonne L
Flavonoids are one of the largest groups of secondary metabolites and are present in plants as aglycones linked to glycosides. LC-MSMS experiments are used in this work to establish the flavonoid content of Euphorbia hirta L. Based on the identification of aglycone ions produced upon collision-induced dissociation (CID), the structural charact(...)

Low temperature curing polyorganosilazane coatings for copper corrosion protection: effect of precursor concentration and relative humidity (R.H.)
Tambi Ramdé, Stefano Rossi, Michele Fedel , Lucien Bonou
In this study, polyorganosilazane (PSZ) material was used to develop thin hybrid organic–inorganic coatings on copper as a protective barrier against corrosion. The coatings were deposited on the copper substrate by sol–gel route, using solution formulations of 3-aminopropyltriethoxysilane substituted polymethyl(hydro)/polymethylsilazane. The(...)
