Glucose detection using sensing materials has lately received interest due to the increased demand for sensitive and selective glucose sensors in pharmaceutical, clinical, industrial settings. Carbon nanotubes (CNTs) are used intensively as a specific class of effective electrode substances electrochemical their large surface area interesting physical characteristics. Nickel is an attractive transition metal electrooxidation with high catalytic activity. In this study, CNT/MoS2/NiNPs...
For the first time, an aqueous micellar medium (sodium dodecyl sulfate, SDS) is used, at Pt electrodes, to electrosynthesize poly(3,4-ethylenedioxythiophene)(PEDOT) conducting films deposited lower potential than in acetonitrile and presenting a well organized structure.
Introduction : L’abcès du psoas est une suppuration profonde muscle psoas-iliaque. Le diagnostic clinique difficile vu la situation anatomique muscle. Il repose essentiellement sur l’échographie abdominale. La prise en charge consiste un drainage complet de l’abcès toujours associé à antibiothérapie fonction nature germe. Méthodologie Nous rapportons série 24 cas colligés au service Chirurgie pédiatrique CHU Aristide Dantec (HALD) Dakar période 10 ans (de 2005 2015). Résultats L’âge moyen 8...
Metal trace elements (MTE) are among the most harmful micropollutants of natural waters. Eliminating them helps improve quality and safety drinking water protect human health. In this work, we used mango kernel powder (MKP) as bioadsorbent material for removal Cr (VI) from water. Uv-visible spectroscopy was to monitor quantify during processing using Beer-Lambert formula. Some parameters such pH, powder, mass contact time were optimized determine adsorption capacity chromium rate. Adsorption...
The photovoltaic performance (efficiency η) of an ITO/CdS/CdTe structure cell is studied in this article according to its electrical properties. study carried out by simulation with SCAPS (Solar Cell Capacitance Simulator) whose mathematical model based on solving the equations Poisson and continuity electrons holes. An conversion efficiency 23.58% obtained optimizing mobility (100 cm2/Vs), that holes (25 density (1015 cm-3), effective states conduction band (7.9 × 1017 cm-3) electronic...
Most reinforced concrete structures in seaside locations suffer from corrosion damage to the reinforcement, limiting their durability and necessitating costly repairs. To improve performance durability, we have investigated this paper Aloe vera extracts as a green inhibitor for reinforcing steel NaCl environments. Using electrochemical methods (zero-intensity chronopotentiometry, Tafel lines impedance spectroscopy), experimental work effect of these (AV) on inhibition bar (HA, diameter 12mm)...
The work describes the use of sulfonic acid-functionalized GCE as a scaffold to build highly sensitive PANI-based sensor for nitrite ions in aqueous medium.
The electropolymerization of 3-methoxythiophene (MOT) was performed on Pt and Fe electrodes in an aqueous micellar medium containing sodium dodecyl sulfate 10-3M bithiophene (BT). Electroactive, homogeneous, adhesive PMOT–PBT composite films are constituted oligomers, including PMOT PBT, traces copolymers. electrocatalytic effect BT the process is demonstrated, allowing electrodeposition coatings iron.
The corrosion behavior of three constructional steels used in Senegal, S235, S275 and S355, was studied simulated atmospheric conditions an exposure chamber above distilled water 3% NaCl solution representing marine atmosphere by comparing the ratio rusted to unrusted area. Electrochemical test methods (potentiodynamic tests electrochemical impedance spectroscopy) were employed study fully immersed acidic, near neutral basic 0.5 M HCl, NaCl, NaOH solutions, respectively. Results indicate...
Abstract Nitrogenous amorphous carbon (a‐CN x ) thin films were deposited by radio‐frequency cathodic magnetron sputtering (13.56 MHz) on polished and etched titanium disks. While these are cheaper to prepare than commonly reported carbon‐based electrodes, the usable electrochemical window in aqueous solution is within same range spans from −1.5 +1.8 V vs. SCE. The reactivity was tested using ferri‐ferrocyanide redox couple as a function of preparation parameters. obtained properties allow...
The valorization of Senegalese attapulgite clay in concrete, as a solution against the exhaustion cement deposits was studied. In that purpose, first calcined at 800°C to make it reactive and added concrete by substitution Portland (CEM I 52.5N) contents 0, 5 10% conserving constant water/cement ratio value 0.65. effects partial replacement on physicochemical mechanical properties well steel-concrete bond were examined. For this water porosity, intrinsic permeability density clay-based...
Abstract Environmental safety is of paramount importance for human well‐being, imposing significant demands affordable, rapid, portable, and robust analytical tools real‐time on‐site water monitoring. In this context, we have developed an method to efficiently detect heavy metal ions, particularly Pb 2+ in samples. This employs a stepwise‐prepared electrode comprised thin film poly(methyl orange) (pMO) electrochemically deposited onto reduced graphene oxide (erGO), which turn coated on...
