TL;DR: In this article, the authors present an overview of aperture and apertureless type scanning near-field optical microscopy (SNOM) techniques that have been developed, with a focus on three-dimensional SNOM methods.

TL;DR: In this paper, the results of room temperature chemical bath deposition (CBD) of highly porous nanostructured PVP-capped Ni(OH) 2 /NiO thin films are presented.

TL;DR: In this article, the authors discuss the recent advances in NiO-based electrodes fabricated using different approaches and different composite forms in order to obtain cells of high efficiency and specific capacitances.

TL;DR: In this paper, the authors provide a review and detailed information on the uses of 3D nickel foam-based electrodes with metal oxides/hydroxides of different morphologies for high-performance pseudocapacitors.

TL;DR: In this article, the local effect of copper nanoparticles (Cu-NPs) on the Fermi energy of graphene domains in large-area graphene thin films was investigated. And the results corroborate the Kelvin-probe force microscopy experiments indicating that the level shifts in the presence of Cu NPs, which break the electron-hole symmetry of graphene due to its weak Van der Waals interactions with Cu even in the absence of chemical bonding and charge transfer.
