In this work, MnO<sub>2</sub> nanowires were integrated with the state-of-art bio-electrochemical system for wastewater treatment, to overcome problems currently encountered with organic, inorganic, heavy metal, and microbe removal, and to minimize the unit footprint (land/space occupation) at low cost.

Rheological behavior of this additive strongly depends on electrochemical condition such as pH, ionic strength and also its content in aqueous solution. So, the effects of these factors have been studied in this paper considering various XG contents as 0.25, 0.5, 1, and 2% of water. Moreover, adjusting pH values such as 3, 5, 7 and 9 in addition to increasing ionic strength to 0.1 and 0.2 in the molar scale has covered a practical range of electrochemical condition. The viscosity of grouts shows an apparent upward trend with an increase in ionic strength and XG content. Also, pH affects the polymerization as much as other parameters. As a result, XG behavior is severely influenced by electrochemical settings <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20condition" title="electrochemical condition">electrochemical condition</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20strength" title=" ionic strength"> ionic strength</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=xhanthan%20gum" title=" xhanthan gum "> xhanthan gum </a> </p> <a href="https://publications.waset.org/abstracts/116666/the-viscosity-of-xanthan-gum-grout-with-different-ph-and-ionic-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116666.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18174</span> Influence of Surface Preparation Effects on the Electrochemical Behavior of 2098-T351 Al–Cu–Li Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rejane%20Maria%20P.%20da%20Silva">Rejane Maria P. da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariana%20X.%20Milagre"> Mariana X.

However, Al-Cu-Li alloys are susceptible to localized corrosion. The near-surface deformed layer (NSDL) induced by the rolling process during the production of the alloy and its removal by polishing can influence on the corrosion susceptibility of these alloys. In this work, the influence of surface preparation effects on the electrochemical activity of AA2098-T351 (Al–Cu–Li alloy) was investigated using a correlation between surface chemistry, microstructure, and electrochemical activity. Two conditions were investigated, polished and as-received surfaces of the alloy. The morphology of the two types of surfaces was investigated using confocal laser scanning microscopy (CLSM) and optical microscopy. The surface chemistry was analyzed by X-ray Photoelectron Spectroscopy (XPS) and energy dispersive X-ray spectroscopy (EDS). Global electrochemical techniques (potentiodynamic polarization and EIS technique) and a local electrochemical technique (Localized Electrochemical Impedance Spectroscopy-LEIS) were used to examine the electrochemical activity of the surfaces. The results obtained in this study showed that in the as-received surface, the near-surface deformed layer (NSDL), which is composed of Mg-rich bands, influenced the electrochemical behavior of the alloy. The results showed higher electrochemical activity to the polished surface condition compared to the as-received one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-Cu-Li%20alloys" title="Al-Cu-Li alloys">Al-Cu-Li alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20preparation%20effects" title=" surface preparation effects"> surface preparation effects</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20techniques" title=" electrochemical techniques"> electrochemical techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=localized%20corrosion" title=" localized corrosion"> localized corrosion</a> </p> <a href="https://publications.waset.org/abstracts/110369/influence-of-surface-preparation-effects-on-the-electrochemical-behavior-of-2098-t351-al-cu-li-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110369.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18173</span> Photo-Electrochemical/Electro-Fenton Coupling Oxidation System with Fe/Co-Based Anode and Cathode Metal-Organic Frameworks Derivative Materials for Sulfamethoxazole Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xin%20Chen">Xin Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinyong%20Li"> Xinyong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Qidong%20Zhao"> Qidong Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Wang"> Dong Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new coupling system was constructed by combining photo-electrochemical cell with electro-fenton cell (PEC-EF). The electrode material in this system was derived from MnyFe₁₋yCo Prussian-Blue-Analog (PBA). Mn₀.₄Fe₀.₆Co₀.₆₇-N@C spin-coated on carbon paper behaved as the gas diffusion cathode and Mn₀.₄Fe₀.₆Co₀.₆₇O₂.₂ spin-coated on fluorine-tin oxide glass (FTO) as anode. The two separated cells could degrade Sulfamethoxazole (SMX) simultaneously and some coupling mechanisms by PEC and EF enhancing the degradation efficiency were investigated. The continuous on-site generation of H₂O₂ at cathode through an oxygen reduction reaction (ORR) was realized over rotating ring-disk electrode (RRDE). The electron transfer number (n) of the ORR with Mn₀.₄Fe₀.₆Co₀.₆₇-N@C was 2.5 in the selected potential and pH range. The photo-electrochemical properties of Mn₀.₄Fe₀.₆Co₀.₆₇O₂.₂ were systematically studied, which displayed good response towards visible light. The photoinduced electrons at anode can transfer to cathode for further use. Efficient photo-electro-catalytic performance was observed in degrading SMX. Almost 100% SMX removal was achieved in 120 min. This work not only provided a highly effective technique for antibiotic treatment but also revealed the synergic effect between PEC and EF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electro-fenton" title="electro-fenton">electro-fenton</a>, <a href="https://publications.waset.org/abstracts/search?q=photo-electrochemical" title=" photo-electrochemical"> photo-electrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=synergic%20effect" title=" synergic effect"> synergic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfamethoxazole" title=" sulfamethoxazole"> sulfamethoxazole</a> </p> <a href="https://publications.waset.org/abstracts/83517/photo-electrochemicalelectro-fenton-coupling-oxidation-system-with-feco-based-anode-and-cathode-metal-organic-frameworks-derivative-materials-for-sulfamethoxazole-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83517.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18172</span> Analysis of Some Produced Inhibitors for Corrosion of J55 Steel in NaCl Solution Saturated with CO₂</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ambrish%20Singh">Ambrish Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The corrosion inhibition performance of pyran (AP) and benzimidazole (BI) derivatives on J55 steel in 3.5% NaCl solution saturated with CO₂ was investigated by electrochemical, weight loss, surface characterization, and theoretical studies. The electrochemical studies included electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), electrochemical frequency modulation (EFM), and electrochemical frequency modulation trend (EFMT). Surface characterization was done using contact angle, scanning electron microscopy (SEM), and atomic force microscopy (AFM) techniques. DFT and molecular dynamics (MD) studies were done using Gaussian and Materials Studio softwares. All the studies suggested the good inhibition by the synthesized inhibitors on J55 steel in 3.5% NaCl solution saturated with CO₂ due to the formation of a protective film on the surface. Molecular dynamic simulation was applied to search for the most stable configuration and adsorption energies for the interaction of the inhibitors with Fe (110) surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibitor" title=" inhibitor"> inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=EFM" title=" EFM"> EFM</a>, <a href="https://publications.waset.org/abstracts/search?q=AFM" title=" AFM"> AFM</a>, <a href="https://publications.waset.org/abstracts/search?q=DFT" title=" DFT"> DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=MD" title=" MD"> MD</a> </p> <a href="https://publications.waset.org/abstracts/115086/analysis-of-some-produced-inhibitors-for-corrosion-of-j55-steel-in-nacl-solution-saturated-with-co2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115086.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18171</span> Synthesis and Electrochemical Characterization of a Copolymer (PANI/PEDOT:PSS) for Application in Supercapacitors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naima%20Boudieb">Naima Boudieb</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Loucif%20Seaid"> Mohamed Loucif Seaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Imad%20Rati"> Imad Rati</a>, <a href="https://publications.waset.org/abstracts/search?q=Imane%20Benammane"> Imane Benammane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to synthesis of a copolymer PANI/PEDOT:PSS by electrochemical means to apply in supercapacitors. Polyaniline (PANI) is a conductive polymer; it was synthesized by electrochemical polymerization. It exhibits very stable properties in different environments, whereas PEDOT:PSS is a conductive polymer based on poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(styrene sulfonate)(PSS). It is commonly used with polyaniline to improve its electrical conductivity. Several physicochemical and electrochemical techniques were used for the characterization of PANI/PEDOT:PSS: cyclic voltammetry (VC), electrochemical impedance spectroscopy (EIS), open circuit potential, SEM, X-ray diffraction, etc. The results showed that the PANI/PEDOT:PSS composite is a promising material for supercapacitors due to its high electrical conductivity and high porosity. Electrochemical and physicochemical characterization tests have shown that the composite has high electrical and structural performances, making it a material of choice for high-performance energy storage applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title="energy storage">energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitors" title=" supercapacitors"> supercapacitors</a>, <a href="https://publications.waset.org/abstracts/search?q=SIE" title=" SIE"> SIE</a>, <a href="https://publications.waset.org/abstracts/search?q=VC" title=" VC"> VC</a>, <a href="https://publications.waset.org/abstracts/search?q=PANI" title=" PANI"> PANI</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%283" title=" poly(3"> poly(3</a>, <a href="https://publications.waset.org/abstracts/search?q=4-ethylenedioxythiophene" title="4-ethylenedioxythiophene">4-ethylenedioxythiophene</a>, <a href="https://publications.waset.org/abstracts/search?q=PEDOT" title=" PEDOT"> PEDOT</a>, <a href="https://publications.waset.org/abstracts/search?q=polystyrene%20sulfonate" title=" polystyrene sulfonate"> polystyrene sulfonate</a> </p> <a href="https://publications.waset.org/abstracts/182320/synthesis-and-electrochemical-characterization-of-a-copolymer-panipedotpss-for-application-in-supercapacitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182320.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18170</span> 1-Butyl-2,3-Dimethylimidazolium Bis (Trifluoromethanesulfonyl) Imide and Titanium Oxide Based Voltammetric Sensor for the Quantification of Flunarizine Dihydrochloride in Solubilized Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajeev%20Jain">Rajeev Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Nimisha%20Jadon"> Nimisha Jadon</a>, <a href="https://publications.waset.org/abstracts/search?q=Kshiti%20Singh"> Kshiti Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Titanium oxide nanoparticles and 1-butyl-2,3-dimethylimidazolium bis (trifluoromethane- sulfonyl) imide modified glassy carbon electrode (TiO2/IL/GCE) has been fabricated for electrochemical sensing of flunarizine dihydrochloride (FRH).

Scanning electrochemical microscopy was used to monitor the chemical activity of the surface and the data was compared with the conventional corrosion results such as potentiodynamic polarization, linear polarization, and immersion tests. The SECM results showed that the chemical reactivity of Mg is higher than phosphate-permanganate-coated Mg. Regions in the vicinity of the galvanic couple boundary are very active in the magnesium phase and fully protected in the iron phase.

The objective of the study is the treatment and characterization of textile wastewater by an electrochemical process. The results obtained at various operational parameters indicated that at 20 minutes of electrochemical process at ( pH =7), initial concentration 10 mg/L, current density 37.5 mA/cm², voltage 9 v and temperature 25⁰C the highest removal efficiency was achieved. The kinetics of removal of selected metal by electrochemical treatment has been successfully described by the first-order rate equation. The results of microscopic techniques using SEM for the scarified electrode before treatment were uniform and smooth, but after the electrochemical process, the morphology was completely changed. This is due to the detection of the adsorbed aluminum hydroxide coming from adsorption of the conducting electrolyte, chemicals used in the experiments, alloying and the scrap impurities of the anode and cathode. The FTIR spectroscopic analysis broad bands at 3450 cm-¹ representing O-H functional groups, while the presence of H-O-H and Al-H groups are indicated by the bands at 2850-2750 cm-¹ and 1099 representing C-H functional groups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical" title="electrochemical">electrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20wastewater" title=" textile wastewater"> textile wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=removal%20efficiency" title=" removal efficiency"> removal efficiency</a> </p> <a href="https://publications.waset.org/abstracts/174364/treatment-and-characterization-of-cadmium-metal-from-textile-factory-wastewater-by-electrochemical-process-using-aluminum-plate-electrode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174364.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18165</span> Embedded Electrochemistry with Miniaturized, Drone-Based, Potentiostat System for Remote Detection Chemical Warfare Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amer%20Dawoud">Amer Dawoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesy%20Motchaalangaram"> Jesy Motchaalangaram</a>, <a href="https://publications.waset.org/abstracts/search?q=Arati%20Biswakarma"> Arati Biswakarma</a>, <a href="https://publications.waset.org/abstracts/search?q=Wujan%20Mio"> Wujan Mio</a>, <a href="https://publications.waset.org/abstracts/search?q=Karl%20Wallace"> Karl Wallace</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of an embedded miniaturized drone-based system for remote detection of Chemical Warfare Agents (CWA) is proposed.

However, the development of an ideal microfluidic system based on LOC technology for diagnostics purposes requires overcoming several obstacles, such as improving sensitivity, selectivity, portability, cost-effectiveness, and prototyping methods. While numerous studies have introduced technologies and systems that advance these criteria, existing systems still have limitations. Electrochemical enzyme-linked immunosorbent assay (e-ELISA) in a LOC device offers numerous advantages, including enhanced sensitivity, decreased turnaround time, minimized sample and analyte consumption, reduced cost, disposability, and suitability for miniaturization, integration, and multiplexing. In this study, we present a novel design and fabrication method for a microfluidic diagnostic platform that integrates screen-printed electrochemical carbon/silver chloride electrodes on flexible printed circuit boards with flexible, multilayer, polydimethylsiloxane (PDMS) microfluidic networks to accurately manipulate and pre-immobilize analytes for performing electrochemical enzyme-linked immunosorbent assay (e-ELISA) for multiplexed quantification of blood serum biomarkers. We further demonstrate fast, cost-effective prototyping, as well as accurate and reliable detection performance of this device for quantification of interleukin-6-spiked samples through electrochemical analytics methods. We anticipate that our invention represents a significant step towards the development of user-friendly, portable, medical-grade, POC diagnostic devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lab-on-a-chip" title="lab-on-a-chip">lab-on-a-chip</a>, <a href="https://publications.waset.org/abstracts/search?q=point-of-care%20diagnostics" title=" point-of-care diagnostics"> point-of-care diagnostics</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20ELISA" title=" electrochemical ELISA"> electrochemical ELISA</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker%20quantification" title=" biomarker quantification"> biomarker quantification</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20prototyping" title=" fast prototyping"> fast prototyping</a> </p> <a href="https://publications.waset.org/abstracts/169509/fast-prototyping-of-precise-flexible-multiplexed-printed-electrochemical-enzyme-linked-immunosorbent-assay-system-for-point-of-care-biomarker-quantification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169509.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18163</span> Pollutants Removal from Synthetic Wastewater by the Combined Electrochemical Sequencing Batch Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Mojiri">Amin Mojiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Akiyoshi%20Ohashi"> Akiyoshi Ohashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomonori%20Kindaichi"> Tomonori Kindaichi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Synthetic domestic wastewater was treated via combining treatment methods, including electrochemical oxidation, adsorption, and sequencing batch reactor (SBR).

The impedance spectra are dependent on the applied dc current density, on the type of cation and on the concentration. When the applied dc current density increases, the diameter of the impedance spectra loops increases because all the components of membrane system resistance increase. The diameter of the impedance plots decreases in the order of Na(I), Ni(II) and Cr(III) due to the increased interactions between the negatively charged sulfonic groups of the membrane and the cations with greater charge. Nyquist plots are shifted towards lower values of the real impedance, and its diameter decreases with the increase of concentration due to the decrease of the solution resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ion-exchange%20membranes" title="ion-exchange membranes">ion-exchange membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=Electrochemical%20Impedance%20Spectrocopy" title=" Electrochemical Impedance Spectrocopy"> Electrochemical Impedance Spectrocopy</a>, <a href="https://publications.waset.org/abstracts/search?q=multivalent%20metal%20cations" title=" multivalent metal cations"> multivalent metal cations</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20system" title=" membrane system"> membrane system</a> </p> <a href="https://publications.waset.org/abstracts/22796/study-of-the-transport-of-multivalent-metal-cations-through-cation-exchange-membranes-by-electrochemical-impedance-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22796.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">529</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18161</span> Electrodeposition and Selenization of Cuin Alloys for the Synthesis of Photoactive Cu2in1-X Gax Se2 (Cigs) Thin Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Benaicha">Mohamed Benaicha</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Allam"> Mahdi Allam </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new two stage electrochemical process as a safe, large area and low processing cost technique for the production of semi-conducting CuInSe2 (CIS) thin films is studied. CuIn precursors were first potentiostatically electrodeposited onto molybdenum substrates from an acidic thiocyanate electrolyte. In a second stage, the prepared metallic CuIn layers were used as substrate in the selenium electrochemical deposition system and subjected to a thermal treatment in vacuum atmosphere, to eliminate binary phase formation by reaction of the Cu2-x Se and InxSey selenides, leading to the formation of CuInSe2 thin film. Electrochemical selenization from aqueous electrolyte is introduced as an alternative to toxic and hazardous H2Se or Se vapor phase selenization used in physical techniques. In this study, the influence of film deposition parameters such as bath composition, temperature and potential on film properties was studied. The electrochemical, morphological, structural and compositional properties of electrodeposited thin films were characterized using various techniques. Results of Cyclic and Stripping-Cyclic Voltammetry (CV, SCV), Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray microanalysis (EDX) investigations revealed good reproducibility and homogeneity of the film composition. Thereby optimal technological parameters for the electrochemical production of CuIn, Se as precursors for CuInSe2 thin layers are determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title="photovoltaic">photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=CIGS" title=" CIGS"> CIGS</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20alloys" title=" copper alloys"> copper alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodeposition" title=" electrodeposition"> electrodeposition</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a> </p> <a href="https://publications.waset.org/abstracts/31570/electrodeposition-and-selenization-of-cuin-alloys-for-the-synthesis-of-photoactive-cu2in1-x-gax-se2-cigs-thin-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31570.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">463</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18160</span> Study of the Adsorption of Metal Ions Ag+ Mg2+, Ni2+ by the Chemical and Electrochemical Polydibenzoether Crown</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalila%20Chouder">Dalila Chouder</a>, <a href="https://publications.waset.org/abstracts/search?q=Djaafer%20Benachour"> Djaafer Benachour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work concerns the study of the adsorption of metal ions Ag +, Mg +, and Ni2+ in aqueous medium by polydibenzoether-ROWN based on three factors: Temperature, time and concentration.

Here, binary mixtures of ILs were prepared with fumed silica nanoparticles and characterized to obtain ILs with conductivity and electrochemical properties optimized for use in energy storage devices.

Fe-BTC was synthesized at room temperature using the noble Iron-trimesate system. The high surface area of as synthesized Fe-BTC proved MOFs as ideal modifiers for glassy carbon electrode. The characterization techniques such as TGA, XRD, FT-IR, BET (BET surface area= 1125 m2/gm) analysis explained the electrocatalytic behaviour of Fe-BTC towards these two drugs. The material formed is cost effective and exhibit higher catalytic behaviour towards analyte systems. The synergism between synthesized Fe-BTC and electroanalytical techniques helped in developing a highly sensitive analytical method for studying the redox fate of ARP and RZ, respectively. Cyclic voltammetry of ferricyanide system proved Fe-BTC/GCE with an increase in 132% enhancement in peak current value as compared to that of GCE. The response characteristics of cyclic voltammetry (CV) and square wave voltammetry (SWV) revealed that the ARP and RZ could be effectively accumulated at Fe-BTC/GCE.

Their early detection is vital and can only be possible by detecting the bacteria causing the disease accurately and rapidly. Great progress has been made in this field with the use of biosensors. Molecularly imprinted polymers have gain broad interest because of their excellent properties over natural receptors, such as being stable in a variety of conditions, inexpensive, biocompatible and having long shelf life. These properties make molecularly imprinted polymers an attractive candidate to be used in biosensors. In this study it is aimed to produce an aptamer-molecularly imprinted polymer based electrochemical sensor by utilizing the properties of molecularly imprinted polymers coupled with the enhanced specificity offered by DNA aptamers. These ‘apta-MIP’ sensors were used for the detection of Staphylococcus aureus and Escherichia coli. The experimental parameters for the fabrication of sensor were optimized, and detection of the bacteria was evaluated via Electrochemical Impedance Spectroscopy. Sensitivity and selectivity experiments were conducted. Furthermore, molecularly imprinted polymer only and aptamer only electrochemical sensors were produced separately, and their performance were compared with the electrochemical sensor produced in this study. Aptamer-molecularly imprinted polymer based electrochemical sensor showed good sensitivity and selectivity in terms of detection of Staphylococcus aureus and Escherichia coli. The performance of the sensor was assessed in buffer solution and tap water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aptamer" title="aptamer">aptamer</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20sensor" title=" electrochemical sensor"> electrochemical sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=staphylococcus%20aureus" title=" staphylococcus aureus"> staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=molecularly%20imprinted%20polymer" title=" molecularly imprinted polymer"> molecularly imprinted polymer</a> </p> <a href="https://publications.waset.org/abstracts/171368/development-of-an-aptamer-molecularly-imprinted-polymer-based-electrochemical-sensor-to-detect-pathogenic-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171368.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18155</span> Electrochemical Sensor Based on Poly(Pyrogallol) for the Simultaneous Detection of Phenolic Compounds and Nitrite in Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Farsadrooh">Majid Farsadrooh</a>, <a href="https://publications.waset.org/abstracts/search?q=Najmeh%20Sabbaghi"> Najmeh Sabbaghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Mostashari"> Seyed Mohammad Mostashari</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolhasan%20Moradi"> Abolhasan Moradi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phenolic compounds are chief environmental contaminants on account of their hazardous and toxic nature on human health. The preparation of sensitive and potent chemosensors to monitor emerging pollution in water and effluent samples has received great consideration. A novel and versatile nanocomposite sensor based on poly pyrogallol is presented for the first time in this study, and its electrochemical behavior for simultaneous detection of hydroquinone (HQ), catechol (CT), and resorcinol (RS) in the presence of nitrite is evaluated. The physicochemical characteristics of the fabricated nanocomposite were investigated by emission-scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), and Brunauer-Emmett-Teller (BET). The electrochemical response of the proposed sensor to the detection of HQ, CT, RS, and nitrite is studied using cyclic voltammetry (CV), chronoamperometry (CA), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS). The kinetic characterization of the prepared sensor showed that both adsorption and diffusion processes can control reactions at the electrode. In the optimized conditions, the new chemosensor provides a wide linear range of 0.5-236.3, 0.8-236.3, 0.9-236.3, and 1.2-236.3 μM with a low limit of detection of 21.1, 51.4, 98.9, and 110.8 nM (S/N = 3) for HQ, CT and RS, and nitrite, respectively. Remarkably, the electrochemical sensor has outstanding selectivity, repeatability, and stability and is successfully employed for the detection of RS, CT, HQ, and nitrite in real water samples with the recovery of 96.2%–102.4%, 97.8%-102.6%, 98.0%–102.4% and 98.4%–103.2% for RS, CT, HQ, and nitrite, respectively. These outcomes illustrate that poly pyrogallol is a promising candidate for effective electrochemical detection of dihydroxybenzene isomers in the presence of nitrite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20sensor" title="electrochemical sensor">electrochemical sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%20pyrogallol" title=" poly pyrogallol"> poly pyrogallol</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=simultaneous%20determination" title=" simultaneous determination"> simultaneous determination</a> </p> <a href="https://publications.waset.org/abstracts/175723/electrochemical-sensor-based-on-polypyrogallol-for-the-simultaneous-detection-of-phenolic-compounds-and-nitrite-in-wastewater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175723.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18154</span> Facial Design of Combined Photoelectrocehmcial-Fenton Coupling Nanocomposites for Antibiotic Eliminations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xinyong%20Li">Xinyong Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new coupling system was constructed by combining photo-electrochemical cell with eletro-fenton cell (PEC-EF).

The two separated cells could degrade Sulfamethoxazole (SMX) simultaneously and some coupling mechanisms by PEC and EF enhancing the degradation efficiency were investigated. The continuous on-site generation of H₂O₂ at cathode through an oxygen reduction reaction (ORR) was realized over rotating ring-disk electrode (RRDE). The electron transfer number (n) of the ORR with Mn₀.₄Fe₀.₆Co₀.₆₇-N@C was 2.5 in the selected potential and pH range. The photo-electrochemical properties of Mn₀.₄Fe₀.₆Co₀.₆₇O₂.₂ were systematically studied, which displayed good response towards visible light.

A single–stranded DNA probe with a thiol modification was covalently immobilized on the surface of the AuE by forming an Au–S bond. Differential pulse voltammetry (DPV) was used to monitor DNA hybridization by measuring the electrochemical signals of reduction of the OB binding to double– stranded DNA (ds–DNA). Our results showed that OB–based DNA biosensor has a decent potential for detection of single–base mismatch in target DNA. Selectivity of the proposed DNA biosensor was further confirmed in the presence of non–complementary and complementary DNA strands. Under optimum conditions, the electrochemical signal had a linear relationship with the concentration of the target DNA ranging from 0.3 nmol L-1 to 240.0 nmol L-1, and the detection limit was 0.17 nmol L-1, whit a promising reproducibility and repeatability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20biosensor" title="DNA biosensor">DNA biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=oracet%20blue" title=" oracet blue"> oracet blue</a>, <a href="https://publications.waset.org/abstracts/search?q=Helicobacter%20pylori" title=" Helicobacter pylori"> Helicobacter pylori</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode%20%28AuE%29" title=" electrode (AuE)"> electrode (AuE)</a> </p> <a href="https://publications.waset.org/abstracts/53867/an-electrochemical-dna-biosensor-based-on-oracet-blue-as-a-label-for-detection-of-helicobacter-pylori" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53867.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">266</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18152</span> Iron(III)-Tosylate Doped PEDOT and PEG: A Nanoscale Conductivity Study of an Electrochemical System with Biosensing Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giulio%20Rosati">Giulio Rosati</a>, <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Sappia"> Luciano Sappia</a>, <a href="https://publications.waset.org/abstracts/search?q=Rossana%20Madrid"> Rossana Madrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Noemi%20Rozl%C3%B2snik"> Noemi Rozlòsnik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The addition of PEG of different molecular weights has important effects on the physical, electrical and electrochemical properties of iron(III)-tosylate doped PEDOT.

Moreover, the conductive films kinetics at the nanoscale, in response to different bias voltages, change radically depending on the PEG molecular weight. The hybrid conductive films show also interesting electrochemical properties, making the PEDOT PEG doping appealing for biosensing applications both for EIS-based and amperometric affinity/catalytic biosensors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy" title="atomic force microscopy">atomic force microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensors" title=" biosensors"> biosensors</a>, <a href="https://publications.waset.org/abstracts/search?q=four-point%20probe" title=" four-point probe"> four-point probe</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-films" title=" nano-films"> nano-films</a>, <a href="https://publications.waset.org/abstracts/search?q=PEDOT" title=" PEDOT"> PEDOT</a> </p> <a href="https://publications.waset.org/abstracts/75824/ironiii-tosylate-doped-pedot-and-peg-a-nanoscale-conductivity-study-of-an-electrochemical-system-with-biosensing-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75824.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18151</span> Electrochemical Performance of Al-Mn2O3 Based Electrode Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noor%20Ul%20Ain%20Bhatti">Noor Ul Ain Bhatti</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Junaid%20Khan"> M.

In this study, Al incorporated Mn<sub>2</sub>O<sub>3</sub> compositions were synthesized to study the effect of Al doping on electrochemical performance of host material. Structural studies were carried out using X-ray diffraction analysis to confirm the phase stability and explore the lattice parameters, crystallite size, lattice strain, density and cell volume. Morphology and composition were analyzed using field emission scanning electron microscope and energy dispersive X-ray spectroscopy, respectively. Dynamic light scattering analysis was performed to observe the average particle size of the compositions. FTIR measurements exhibit the O-Al-O and O-Mn-O and Al-O bonding and with increasing the concentration of Al, the vibrational peaks of Mn-O become sharper. An enhanced electrochemical performance was observed in compositions with higher Al content. <p class="card-text"><strong>Keywords:</strong> <a
