“…For as-prepared TNTs and MoS2-TNTs, the obtained capacity fades with cycle number unlike to the Al2O3/MoS2/Al2O3-TNTs. This is attributed to the beneficial effects of the Al2O3-coating on the TNTs, which are in agreement with works reported in the literature [25,29,51,52]. 3 [49,50].…”

“…To overcome these problems, surface modification of the TNT layers by coating, decorating, and doping with various materials have been extensively explored [6,[25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Because of the low volumetric expansion and high porosity, the surface modified TNT layers deliver high capacity, while keeping the mechanical stability of the nanostructured electrode.…”

TiO2 nanotube layers (TNTs) decorated with Al2O3/MoS2/Al2O3 are investigated as a negative electrode for 3D Li-ion microbatteries. Homogenous nanosheets decoration of MoS2, sandwiched between Al2O3 coatings within self-supporting TNTs was carried out using atomic layer deposition (ALD) process. The structure, morphology, and electrochemical performance of the Al2O3/MoS2/Al2O3-decorated TNTs were studied using scanning transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and chronopotentiometry. Al2O3/MoS2/Al2O3-decorated TNTs deliver an areal capacity almost three times higher than that obtained for MoS2-decorated TNTs and as-prepared TNTs after 100 cycles at 1C. Moreover, stable and high discharge capacity (414 µAh cm−2) has been obtained after 200 cycles even at very fast kinetics (3C).

“…Nanostructure such as CdS, SnO 2 , TiO 2 , ZnS, ZnO, etc. with particular morphologies has drawn growing attention in the latest years due to their technological applications and unique optical characteristics [1][2][3][4][5]. Zinc oxide (ZnO) is a versatility of the II-VI direct band gap semiconductor with a large 3.37 eV band gap with a large 60 meV excitonic binding energy [6][7][8][9].…”

The impact of europium (Eu 3+) ion doping has been outlined in improving the structure and optical properties of macroporous honeycomb-like zinc oxide (ZnO) nanoparticles, produced by the gel-combustion technique by changing the quantity of dopant. The X-ray diffraction (XRD) research verified that the hexagonal wurtzite structure of ZnO was not disturbed by Eu 3+ substitution. Scherrer method, Scherrer plots (SP), Williamson-Hall (W-H) plots and Size-Strain plots (SSP) were used to estimate the crystallite size. Decreased crystallite size in ZnO:Eu 3+ was noticed along with lower angle shift of XRD peaks and increased lattice parameters such as unit cell volume that can be described as replacement result of Eu 3+ at Zn sites. Fourier transform infrared (FTIR) spectroscopy analysis confirmed the Eu 3+ dopant by moving the peak from 474 cm −1 to 525 cm −1. Field-emission scanning electron microscopy (FESEM) pictures verified macroporous honeycomb-like structures. UV-Visible (UV-Vis) absorption spectroscopic studies show that the ability of ZnO:Eu 3+ nanoparticles concerning the absorption of visible light increased upon Eu 3+ doping with a red shift compared to ZnO nanoparticles. Photoluminescence (PL) emission spectra of Eu 3+ doped ZnO nanoparticles exhibited five intense band emissions at 579, 591, 617, 652, and 706 nm ascribed to 5

We investigate the electronic properties of blue-phosphorene nanotubes using density functional theory first-principle calculations, taking into account, in particular, the presence of atom vacancies in the structure. The study considers both zigzag and armchair achiral configurations and reports on the structure and the electron energy states of the nanostructure. Compared to pristine blue-phosphorene nanotubes, which exhibit values of the fundamental bandgap between one and two electron-volts. For atomic single vacancies, the incorporation of spin-polarization helps to identify the induction of localized mid-gap states in the blue phosphorene nanotubes. The difference of energy between the highest near-valence and lower near-conduction localized states is, approximately, of 0.5 eV. Also the increase of the single vacancies concentration leads to the formation of additional bands that change the energy gap of the system.
