We report the synthesis of klockmannite (CuSe) via a three-probe electrochemical set-up (chronoampereometry). The structural properties are examined by X-ray diffraction and Raman spectroscopy. Field emission scanning electron microscopy (FESEM) analysis revealed formation vertically aligned CuSe nanosheets with an average thickness 34 nm lateral size 700 nm. exhibit impressive field characteri...

Implementation of microbial fuel cells (MFCs) for electricity production requires effective current generation from waste products via robust cathode reduction. Three cathode types using dissolved oxygen cathodes (DOCs), ferricyanide cathodes (FeCs) and air cathodes (AiCs) were therefore assessed using bioethanol effluent, containing 20.5 g/L xylose, 1.8 g/L arabinose and 2.5 g/L propionic acid...

The hardness and wear resistance of amorphous Al–Mn alloy coatings can be improved by incorporating ceramic particles into them to extend their application. In this paper, Al–Mn/WC composite have been prepared with electrodeposition in stirred AlCl3–NaCl–KCl–MnCl2 molten salts at 180 °C the addition WC particles. effects stirring speed (400–700 rpm) cathode current density (15–75 mA/cm2) on pro...

In this study, we propose dibenzo[b,f][1,5]diazocine/ZnO organic/inorganic hybrid photoanode for application in the photoelectrochemical water splitting. The electrode consisting of inorganic ZnO nanorod (ZnO NR) array structures and organic diazocine derivative film with or without platinum nanoparticle (Pt NP) cocatalyst was examined. morphology characterization performed by FESEM. UV-vis abs...

The large amount of molasses that are generated in sugar-processing companies not always redistributed for commercialization by-products. Because this, the present research uses these wastes as fuel low-cost, lab-scale, single-chamber microbial cells. Zinc and copper electrodes were used 100 mL molasse chamber fuel, managing to generate current voltage peaks 1.73 ± 0.13 mA 0.953 0.142 V. In mon...

High entropy alloy attracts great attention for its high thermal stability and corrosion resistance. A CoCrFeNiMn high-entropy coating was deposited on grey cast iron through plasma transfer arc cladding. It formed fine acicular martensite near the iron, with columnar grains perpendicular to interface between substrate cladding layer as well dendrite in middle part of coatings. Simple FCC solid...
