The present study aims at designing a promising Microbial Fuel Cell (MFC) to utilize wastewater in order to generate electricity. Two types of salt bridge have been used in MFC (KCl and NaCl). The maximum electricity generation with 1M KCl and NaCl has been 823 and 713 mV, respectively. Varied salt concentrations (0.5M, 1M, 2M, and 3M) of salt bridge in MFC have been analyzed with different fac...

Electronic tongues are devices used in the analysis of aqueous matrices for classification or quantification tasks. These systems composed several sensors different materials, a data acquisition unit, and pattern recognition system. Voltammetric have been electronic using cyclic voltammetry method. By this method, each sensor yields voltammogram that relates response current to change voltage a...

We explore the fabrication, physicochemical characterisation (SEM, Raman, EDX and XPS) and electrochemical application of hand-drawn pencil electrodes (PDEs) upon an ultra-flexible polyester substrate; investigating the number of draws (used for their fabrication), the pencil grade utilised (HB to 9B) and the electrochemical properties of an array of batches (i.e, pencil boxes). Electrochemical...

Creatinine is the final metabolic product of creatine in muscles and a widely accepted biomarker for chronic kidney disease. In this work, we present non-enzymatic sensor based on an electrochemical pretreated screen-printed carbon electrode (PTSPCE) with electrodeposited Cu nanoparticles (CuNPs). To function PoC format, prepared PTSPCE/CuNPs sensors were used as disposable elements portable po...

electrochemical properties of various rock-shaped-cuo/graphite (g) composites and monoclinic structure cuo nanoparticles as the cathode versus a zinc plate as the anode in a 4m naoh electrolyte were elucidated by electrochemical impedance spectroscopy (eis) and chronopotentiometry (cp) in a two electrode configuration cell. various values of g 9, 16 and 28 wt% were prepared and studied as catho...

An enzymatic biofuel cell is integrated on a screen-printed electrode as basis for self-powered biosensor. A glucose/O2 consisting of pyrroloquinoline quinone-dependent glucose dehydrogenase embedded within an Os-complex modified redox polymer bioanode to oxidize and non-limiting bilirubin oxidase-based gas diffusion biocathode in the direct-electron transfer regime reduction O2 showed glucose-...

Environmental monitoring is necessary to understand and evaluate the extent of pollution and eco-system disturbances and to work out remedial strategies. Electrochemical methods are attractive for environmental monitoring due to their capability for remote and in situ applications. The electrode-based sensors are prone to fine-tuning and modification to improve the selectivity and sensitivity f...
