Yibor Fabrice Roland Bako, Serge Foukmeniok Mbokou, Boukaré Kaboré, Issa Tapsoba, Maxime Pontié
Electrochemical detection of 3-methyl-4-nitrophenol (MNP) in direct phenol oxidation occurs at high potentials and generally leads to progressive passivation of the electrochemical sensor. This study describes the use of a carbon
fiber microelectrode modified with a tetrasulfonated nickel phthalocyanine complex for the detection of MNP at a(...)

Etude du comportement électrochimique des flavonoïdes dans l’extrait à l’acétate d’éthyle de Euphorbia hirta L.
Yssouf Karanga, Amidou Tall, Yibor Fabrice Roland Bako, Ousmane Ilboudo, Issa Tapsoba
Les extraits de plante sont des mélanges complexes de composés tels que les flavonoïdes dont l’identification nécessite des méthodes conventionnelles souvent sophistiquées et coûteuses. Il est donc nécessaire de développer des méthodes plus simples et abordables en termes de faible coût et de facilité de mise en œuvre pour l’identification de(...)

Identification des interactions flavonoïde-flavonoïde par évaluation in vitro du pouvoir antioxydant de mélanges binaires
HIEN Nabomo, OUEDRAOGO Jean Claude W., BONZI-COULIBALY Yvonne L.
Les flavonoïdes co-présents dans un extrait de plante créent entre eux des interactions moléculaires. L’investigation de ces interactions flavonoïde-flavonoïde a été menée par l’évaluation in vitro de l’activité antioxydante des mélanges binaires de neuf (09) flavonoïdes préparés dans du méthanol. La capacité antioxydante a été évaluée par deu(...)

Molecular imprinted polymer modified carbon ultramicroelectrode for a selective detection of 3‑methyl‑4‑nitrophenol and its bioremediation in a fungal microbial fuel cell
Yibor Fabrice Roland Bako, Jean-Philippe Théodore Silga, Serge Mbokou Foukmeniok, Maxime Pontié
In the present work, we have developed for the first time a carbon ultramicroelectrode modified by a molecular imprinted polymer (MIP) for selective determination of 3-methyl-4-nitrophenol (MNP) in aqueous media. The polymeric film based on a non-covalent approach was obtained by electropolymerization of ortho-phenylenediamine in the presence(...)

Leaching of Base Metals in Pcbs and Copper Cementation by Iron Powder
Francis O. Konatéb, Véronique Vitry , Arsène H. Yonli
When dealing with electronic waste, printed circuit boards (PCBs) are some of the most important materials in terms of recovery possibilities, because of their high content of precious metals and base metals, notably copper ( 20% w/w), in addition to organic resins and ceramic materials. Efficient hydrometallurgical metals recovery from electr(...)

Preparation and characterization of foamed concrete using a foaming agent and local mineral resources from Burkina Faso
Alassane Compaoré, Moustapha Sawadogo, Youssouf Sawadogo, Moussa Ouedraogo, Brahima Sorgho, Mohamed Seynou, Philippe Blanchart, Lamine Zerbo
Lightweight-foamed concretes (LFC) were formulated from cement, natural sand, and foam from a
foaming agent with densities of 600 and 700 kg/m3. The identified mineral phases in the cement are
alite, belite, celite, ferrite, calcite, and gypsum. The obtained foamed concretes have a porosity varying
from 29.17 to 37.14 vol%, a thermal conduc(...)

Optimization of the Extraction of Phenolic Compounds from Eucalyptus camaldulensis Dehnh Leaves Using Response Surface Methodology
OUATTARA Bassalia, SEMAY Irène, OUEDRAOGO Jean Claude W., GERBAUX Pascal, OUEDRAOGO Igor W. K.
In this work, the optimization of phenolic compounds extraction from Eucalyptus camaldulensis leaves was carried out by applying a response surface methodology (RSM) approach. The influence of different parameters i.e., the liquid-to-solid ratio, the temperature and the extraction time have been jointly tested by maceration in an ethanol–water(...)

Gold phthalocyanine-based materials can allow to combine the unique physical properties of the metallophthalocyanine with gold for numerous applications such as (photo)-electrochemistry or the so-called single atom catalysts (SACs), which require very small amounts of metal. However, there is currently a lack of physico-chemical and electroche(...)
