We present an extended X-ray absorption fine structure study at the Mo K-edge of A2(Mo1−yMny)2O7 (A = Gd, Ho; y 0.05 and 0.10) pyrochlores, as a function temperature composition, coupled to diffractometric magnetic characterizations. Extending reported in our previous paper on pristine A2Mo2O7 compounds these Mo/Mn partially substituted samples, where we hypothesize competition between double-e...

Herein, we report bifunctional molybdenum-doped nickel sulfide on foam (Mo-NiSx/NF) for magnetic field-enhanced overall water splitting under alkaline conditions. Proper doping of Mo can lead to optimization the electronic structure NiSx, which accelerates dissociation H2O and adsorption OH− in hydrogen evolution reaction (HER) oxygen (OER) processes, respectively. In addition, magnetically act...

In the present study, Co-ZnO and Co-Ni-ZnO nanoparticles were synthesized by sonochemical methods and the structural and optical properties were investigated through Fourier Transform Infrared spectroscopy (FTIR), UV-Vis spectroscopy, Field Emission Scanning Electron Microscopy (FE-SEM), X-Ray Diffraction (XRD), and Photoluminescence spectroscopy (PL) methods. Morphology of nanoparticles obtain...

Manipulating structure, defects and composition of a material at the atomic scale for enhancing its physical or mechanical properties is referred to as nanostructuring. Here, by combining advanced microscopy techniques, we unveil how formation of highly regular nano-arrays of nanoparticles doubles the strength of an Fe-based alloy, doped with Ti, Mo, and V, from 500 MPa to 1 GPa, upon prolonged...

TiO2 coatings deposited using reactive magnetron sputtering and spray coating methods, as well as Agand Mo-doped TiO2 coatings were investigated as self-cleaning surfaces for beverage processing. The mechanical resistance and retention of the photocatalytic properties of the coatings were investigated over a three-month period in three separate breweries. TiO2 coatings deposited using reactive ...

Abstract For the first time, single crystals of undoped lithium tungstate and doped by 1.25% molybdenum were grown low-temperature-gradient Czochralski technique. The standard formation enthalpies, lattices stabilization energies, heat capacity determined in temperature range 320-997 K. lattice enthalpy dependence on Mo content was constructed.

The clean conversion of carbon dioxide and water to a single multicarbon product O2 using sunlight via photocatalysis without the assistance organic additives or electricity remains an unresolved challenge. Here we report bio-abiotic hybrid system with non-photosynthetic, CO2-fixing acetogenic bacterium Sporomusa ovata grown on scalable cost-effective photocatalyst sheet consisting pair particu...

Manganese oxide (MO) has been synthesised by chemical co-precipitation method and it was characterised for its functional group, phase structure, particle size morphology using FTIR, XRD, SEM TEM. Additionally, electrochemical properties like cyclic voltammetry (CV), galvanostatic charge/ discharge impedance spectroscopy (EIS) are recorded. The specific capacitance of the prepared manganese is ...

Glassy carbon electrode (GCE) was modified with metal oxides (MO = Fe3O4, ZnO) nanoparticles doped phthalocyanine (Pc) and functionalized MWCNTs, and the electrocatalytic properties were studied. Successful synthesis of the metal oxide nanoparticles and the MO/Pc/MWCNT composite were confirmed using FTIR, Raman and SEM techniques. The electrodes were characterized using cyclic voltammetry (CV) ...
