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(...)

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(...)

Sorption of Bisphenol A as Model for Sorption Ability of Organoclays
S. Issaka Garikoé, Boubié Guel and Ingmar Persson
he arrangement of bisphenol A molecules into organoclays and their interactions with the intercalated surfactant were studied. The organoclays were prepared via solid-state intercalation of four cationic surfactants, such as dodecyltrimethyl-, tetradecyltrimethyl-, hexadecyltrimethyl-, and didodecyldimethyl-ammonium, as bromide salts, at diffe(...)

Flavonoid-Metallic Cation Interactions Studied by Antioxidant Potential of Mixtures in Methanolic Solution
HIEN Nabomo, OUEDRAOGO Jean Claude W., BONZI-COULIBALY Yvonne L.
Flavonoid-metal cation interactions were studied via antioxidant property evaluation with binary mixtures of 08
flavonoids with 10 metal cations at different concentrations. We have shown in the analysis by DPPH. Radical method, that despite different behaviors of metals, antioxidant capacity is reduced for some mixtures in methanolic solutio(...)

Fluoride Removal in Synthetic Drinking Water by Electrocoagulation Using Aluminum Electrodes.
Moudassirou Sedou, Seyf-Laye Alfa-Sika Mande, Yacouba Sanou, Kadidja Arouna
Fluoride is recognized as an essential constituent in the human diet. Low fluoride concentration could prevent dental problem while higher fluoride concentration will cause dental and skeletal fluorosis. This study aimed to remove fluoride in synthetic drinking water by electrochemical system. It had been performed at laboratory scale using fl(...)

Synthesis and study of physicochemical properties of a hybrid species : Iron phthalocyanine –silver nanoparticles
Lassané Tarpaga, Bintou Sessouma, Seydou Ouédraogo, Vincent Colliere, Mabinty Bayo-Bangoura, Catherine Amiens, Karifa Bayo.
This article reports a strategy to synthesize a hybrid species made of iron phthalocyanine (FePc) grafted to the surface of silver nanoparticles. The affinity between sulfur and silver on the one hand, and the aptitude of the FePc complex to bind pyridine axially on the other, allowed us to use thiopyridine as a linker between the two entities(...)
