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(...)

Evaluation of Combined Landscape Restoration Practices on Soil Organic Carbon Stocks in Semiarid Regions of Burkina Faso
Stéphanie Batchakoué Maïga-Yaleu, Abdul-Charif Cissé, Sibiry Albert Kaboré, Damien Hauswirth, Oumarou Malam Issa, Maguette Kaire, Ibrahim Bouzou Moussa, Hassan Bismarck Nacro
Forest and landscape restoration (FLR) practices have been reported to improve soil organic carbon stocks (SOCs) and contributing to climate change mitigation. This study aims to evaluate the impact of combined FLR practices, mainly developed in semiarid regions, on SOCs. The SOCs, soil texture, bulk density (ρ), pH, CO2 emissions, and herbace(...)

The Use of Plants for Drinking Water Disinfection: Traditional Knowledge, Scientific Validation, Current Challenges and Prospects for the Future
NITIEMA YEFANOVA Svitlana L., OUEDRAOGO Jean Claude W., OUEDRAOGO Benjamin, BONZI-COULIBALY Yvonne L.
Nowadays, water treatment is a big issue in rural areas especially in African countries. Due to lack of water purification facilities or the high cost of modern water treatment technologies, attempts have been made to find alternative natural methods to treat drinking water. Through an investigation of knowledge about traditional practices bas(...)
