Aqueous rechargeable Zn//MnO2 batteries have attracted extensive research interest owing to their low cost and high energy density. However, the slow reaction kinetics, disproportionation of MnO2 cathode, irreversible phase transition mechanism considerably restrict development. Here, we chose Mo-doped α-MnO2 (Mo–MnO2) as cathode material proposed a stable N–H⋯O bond-reinforced interaction form...

Abstract Nanostructured pure and molybdenum (Mo)-doped nickel oxide (NiO) thin films with various concentrations of Mo dopants were successfully sputtered on indium-doped tin (ITO) substrates to apply in the ultraviolet (UV) photodetector sensors. The influence concentration films' structural, morphological, optical properties was studied using X-ray diffraction (XRD), field emission scanning e...

Magnetization and Hall resistivity have been investigated for single crystals of Dy-doped Nd2Mo2O7. A sharp decrease of the Hall resistivity upon a metamagnetic transition, perhaps associated with magnetic-field (H) induced flop of Dy moments, has been observed in the Dy-doped crystals only for H ‖ [111] direction. In addition, the sign of the Hall resistivity at a high field, both for H ‖ [100...

Mo, Cu-doped CeO2 (CMCuO) nanopowders were synthesized by the nitrate-fuel combustion method aiming to improve electrical and electrochemical properties of its Mo-doped (CMO) parent addition copper. An conductivity ca. 1.22·10−2 S cm−1 was measured in air at 800°C for CMCuO, which is nearly 10 times higher than that reported CMO. This increase associated with inclusion copper into crystal...

in this paper we propose and simulate a new heterostructure mesfet, called δ-doped ldd hmesfet. to improve carrier velocity in vicinity of the source in channel of gaas mesfet, one can replace source with alxga 1-x as. by increasing al content, discontinuity of hetero-interface could be increased. therefore, the velocity increases in the low field. however, increasing al mole fraction in excess...

The photoswitching behavior of the polyacrylic acid (PAA) doped by methyl orange (MO) brush film was investigated using spectral analysis UV-Vis absorbance, Fourier Transformation Infrared spectroscopy, 2D electrical conductivity mapping and Atomic Force Microscopy. kinetics time evolution photoisomerization PAA-MO PEBs from E-state to Z-state UV-light irradiation, reverse thermal relaxation ex...
