Self-Immolative Systems in Diagnostic and Therapeutic Applications
Windbedema Prisca Ouédraogo, Thomas Cailly, Valérie Collot
Self-immolative systems first emerged in prodrug chemistry in the 1980s. Since then, several types of self-immolative systems have been developed. Despite their structural differences, all self-immolative systems operate on the same principle: an intramolecular reaction cascade triggered by a specific stimulus, ultimately leading to the releas(...)

Application d’un biotraitement membranaire à l’abattement de la teneur en micropolluants d’une eau usée synthétique
Jean de Dieu Zongo, Yacouba Sanou
Les effluents des stations d'épuration contiennent des polluants organiques, inorganiques et microbiens, représentant une source majeure de contamination des eaux et des sols. Ce travail vise à étudier le biotraitement des eaux usées en vue d’éliminer le bisphénol A (BPA), la demande chimique en oxygène (DCO), l’ammonium (NH4+) et les ortho-ph(...)

Lassané Tarpaga, Aristide W G Nitiema, Seydou Ouédraogo, Bertrand Ouemega, Bintou Sessouma, Mabinty Bayo-Bangoura, Karifa Bayo
We have prepared and isolated in solid form two types of polymers formed between iron (II) complexes ([FePc(COOH)8] and [FePc(CN)8]) and two bidentate ligands [trans-1,2-bis (4-pyridyl) ethylene (bpe); trans-1,2-bis (4-pyridyl) ethane (bpa)]. The electronic and vibrational absorption spectra of these complexes are discussed in comparison with(...)

Characterization of Local Clay from Burkina Faso for the Removal of Lead from Groundwater
Arzouma Christophe Guissou, Dimanche Regie Ouedraogo, Brahima Sorgho*, Yacouba Soutra
The contamination of water resources by trace metals (TMs), particularly lead
(Pb2+), is a significant public health and environmental concern, especially in
areas where access to modern treatment technologies is limited. The adsorbent
material used is KOM clay, collected from Kombissiri, near Ouagadougou, in
Burkina Faso, and characte(...)

Influence of anodizing processes on corrosion performance of AA5005 aluminium alloy
Ramdé Tambi
To investigate the effects of anodizing processes on the corrosion performance of alloy AA5005, a series of electrochemical and salt spray tests was conducted. Test results showed that the corrosion performance of anodized AA5005 depends both on anodizing time and the sealing process. Scanning electron microscopic (SEM) examination revealed mu(...)

Évaluation de l’efficacité anticorrosion de prétraitements à base de silanes (MPTMS et TMSPEA) sur l'acier au carbone 1018 en milieu chloruré
Ramdé Tambi
Parmi les nombreuses méthodes utilisées pour prévenir la corrosion, les traitements de surface à base de silane sont considérés comme écologiques et efficaces en raison de leur faible toxicité et de leurs excellentes propriétés d'adhérence. Il est essentiel de développer un revêtement anticorrosion efficace, économique et respectueux de l'envi(...)

DFT Analysis of the Gas Phase Interactions of Choline Chloride with Urea
Dan E. Diendere1, Edouard Tapsoba2, Françoise Diendere1,*, Moussa R. Bougouma1
Choline chloride and urea interact to form a Deep Eutectic Solvent widely used as a green solvent in several
applications such as electrochemistry, chemical substance separation and reactions. We searched for the equilibrium
geometries, charges distributions of model compounds of their respective associated complexes of 1:1, 1:2 and 1:3 ra(...)

Direct Electrochemical Analysis of 3-Methyl-4-Nitrophenol in Water Using Carbon Fiber Microelectrode Modified with Nickel Tetrasulfonated Phthalocyanine Complex
Yibor Fabrice Roland Bako, Boukaré Kaboré, Amidou Tall, Wendepoui Félix Sawadogo, Issa Tapsoba
This study reports a tetrasulfonated nickel phthalocyanine complex (p-NiTSPc) modified carbon fiber microelectrode (CFME) for the detection of 3-methyl-4-nitrophenol (MNP) at low potentials. The voltammogram of MNP showed a cathodic peak at −0.86 V vs Ag/AgCl corresponding to the reduction of the nitro group. An electrocatalytic activity towar(...)
