Modulating the electrical properties of organic heterojunction devices based on phthalocyanines for ambipolar sensors
Seydou Ouedraogo, Rita Meunier-Prest, Abhishek Kumar, Mabinty BayoBangoura, and Marcel Bouvet
Although ambipolar materials are highly studied in organic electronics, they are rarely used in gas sensors. In
the present work, we studied ammonia sensing on organic heterojunctions in a bilayer configuration composed of
octachlorinated metallophthalocyanines (M(Cl8Pc); M: Co, Cu and Zn) as a sublayer and lutetium bis-phthalocyanine (LuPc2(...)

Development and validation of an original magneto-chromatography device for the whole blood determination of hemozoin, the paramagnetic malaria pigment
Orokia Traore, Moussa Compaore, Philippe Okusa, François Hubinon, Pierre Duez, Bertrand Blankert, Martin Kindrebeogo
Background: Malaria remains the first global parasitic endemic disease with more than 400,000 deaths per year;
there is a definite need for prevention measures and treatments, but also for rapid and low-cost diagnostic methods. Hemozoin, a detoxification polymer formed from heme by the parasite, and a likely biomarker of infection, has entice(...)

Characterization of a natural laterite of Burkina Faso for the elimination of arsenic (III) and arsenic (V) in ground water
Régie Dimanche OUEDRAOGO, Corneille BAKOUAN, Brahima Sorgho, Boubié Guel, Lucien BONOU .
Arsenic is one of the major pollutants in borehole water and is an international concern because of its adverse effects on human health. In this study, a lateritic material was used for the removal of arsenic (III) and arsenic (V) in aqueous solution. The laterite used is referenced DA and characterized by different physico-chemical methods (D(...)

Study of the Mechanical Behaviour of Mortars Modified with Rice Husk Ash
Issiaka Sanou, Moustapha Sawadogo, Mohamed Seynou, Lamine Zerbo, Raguilnaba Ouedraogo
The purpose of this work is to study the influence of Rice Husk Ash (RHA)
on the mechanical strength of mortars. For this purpose, ash was produced by
calcining rice husk at 680˚C for 5 hours to produce reactive pozzolan. The
chemical and mineralogical composition studied by Inductively Coupled
Plasma-Atomic Emission Spectrometry (ICP-(...)

p-Type and n-type conductometric behaviors of octachlorometallophthalocyanine-based heterojunctions, the key role of the metal
Seydou Ouedraogo, Tahirou Coulibaly, Rita Meunier-Prest, Mabinty Bayo-Bangoura and Marcel Bouvet
In the present work, we determined the electrical properties of octachlorinated
metallophthalocyanines with Co(II) and Cu(II) ions as metal centers. We engaged them in heterojunctions,
with lutetium bisphthalocyanine as a partner. Surprisingly, cobalt and copper complexes show opposite
behaviors, the first being an n-type material whereas t(...)

Assessing the Source of Thallium Contamination in Ground and Surface Waters in the Locality of Yamtenga (Burkina Faso): Correlation with some heavy metals Ions
Ollé Rodrigue Kam, Corneille Bakouan, Inoussa Zongo, Boubié Guel,
Thallium (Tl) is a non-essential element for human being and is considered as a highly toxic trace
element at a concentration above 2 µg/L. To assess the source of thallium contamination in ground
and surface waters in the locality of Yamtenga village (11°43'35.1'' N and 00°11'50.8'' W, Burkina
Faso), chemical analyzes of thallium concentra(...)

Growth and characterization of WSe2 single crystals usingTeCl4 as transport agent
Moussa Bougouma, Bernard Nisol, Thomas Doneux, Boubié Guel, Tiriana Segato, François Reniers, Marie-Paule Delplancke-Ogletree, Jean B. Legma, Claudine Buess-Herman,
The growth of WSe2 single crystals, using TeCl4 as transport agent was performed successfully from slowly cooled polycrystalline powders as precursors. The resulting single crystals were characterized by X-ray diffraction (XRD) and their surfaces examined by scanning electron microscopy (SEM) presented fewer defects than single crystals prepar(...)

Direct and simultaneous quantifcation of rutin and quercetin in natural fruits base on purifed Arabic Gum modifed carbon paste electrode
Serge Mbokou Foukmeniok, Ousmane Ilboudo, Yssouf Karanga, Issa Tapsoba, Evangéline Njanja & Ignas Tonle Kenfack
Arabic gum was purified and used as modifier of carbon paste electrode (PAG-CPE) for the simultaneous determination of quercetin (QT) and rutin (RT) in 0.1 M phosphate buffer solution, pH 6.0. Fourier transform infrared spectroscopy was used for the identification of different chemical functional groups present at the surface of the raw and th(...)

Déterminants de l’adoption des bonnes pratiques de gestion durable des terres dans un contexte de changement climatique au Nord Bénin : cas de la fumure organique
Kamarou Din ADEBIYI, Stéphanie MAIGA-YALEU, Kassimou ISSAKA Moudachirou AYENA et Jacob Afouda YABI
L'un des problèmes majeurs qui affectent la production agricole dans le Nord du Bénin, est la baisse de la fertilité des sols. En réponse à ce phénomène les agriculteurs s‟y adaptent à travers l'adoption des bonnes pratiques de Gestion Durable des Terres (GDT) parmi lesquelles l‟utilisation de la fumure organique. Cette étude a pour objectif l(...)

Seydou Ouedraogo , Bilel Choucheneb, , Christophe Desmarets , Thomas Gries , Lavinia Balane , René Fournet , Ghouti Medjahdi , Karifa Bayo , Raphaël Schneiderb
In this paper, copper octacarboxyphthalocyanine (CuPc) was demonstrated to be an efficient photosensitizer of
graphitic carbon nitride (g-CN) for the degradation of dyes like Orange II or Methylene Blue under visible light
irradiation. UV–vis absorption, photoluminescence and photocurrent measurements demonstrate that CuPc not
only allows t(...)
