g-CN-coated MnO hollow nanorod cathode for stable aqueous Zn-ion batteries

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 2,   Pages 217-225 doi: 10.1007/s11705-022-2214-7

Abstract: Aqueous zinc-ion batteries are attracting considerable attention because of their high safety compared with conventional lithium-ion batteries. Manganese-based materials have been widely developed for zinc-ion batteries cathode owning to their low cost, high security and simple preparation. However, the severe volume expansion and poor stability during charging and discharging limit the further development of manganese-based cathodes. Herein, superior α-MnO2@g-C3N4 was successfully prepared for stable zinc-ion batteries (ZIBs) cathode by introducing g-C3N4 nanosheets. Compared with pure α-MnO2, α-MnO2@g-C3N4 has a specific capacity of 298 mAh·g–1 at 0.1 A·g–1. Even at 1 A·g–1, the α-MnO2@g-C3N4 still retains 100 mAh·g–1 (83.4% retention after 5000 cycles), implying its excellent cycling stability. The α-MnO2@g-C3N4-based cathode has the highest energy density (563 Wh·kg–1) and power energy density (2170 W·kg–1). This work provides new avenues for the development of a wider range of cathode materials for ZIBs.

Analytical and numerical investigation into the longitudinal vibration of uniform nanotubes

Masoud MASOUMI,Mehdi MASOUMI

Frontiers of Mechanical Engineering 2014, Volume 9, Issue 2,   Pages 142-149 doi: 10.1007/s11465-014-0292-z

Abstract:

In recent years, prediction of the behaviors of micro and nanostructures is going to be a matter of increasing concern considering their developments and uses in various engineering fields. Since carbon nanotubes show the specific properties such as strength and special electrical behaviors, they have become the main subject in nanotechnology researches. On the grounds that the classical continuum theory cannot accurately predict the mechanical behavior of nanostructures, nonlocal elasticity theory is used to model the nanoscaled systems. In this paper, a nonlocal model for nanorods is developed, and it is used to model the carbon nanotubes with the aim of the investigating into their longitudinal vibration. Following the derivation of governing equation of nanorods and estimation of nondimensional frequencies, the effect of nonlocal parameter and the length of the nanotube on the obtained frequencies are studied. Furthermore, differential quadrature method, as a numerical solution technique, is used to study the effect of these parameters on estimated frequencies for both classical and nonlocal theories.

Hydrothermal synthesis of crystalline α-/β-MnO2 nanorods via γ-MnOOH nanorod precursors

ZHANG Weixin, REN Xiangbin, YANG Zeheng, WANG Hua, WANG Qiang, HUANG Fei

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 4,   Pages 365-371 doi: 10.1007/s11705-007-0066-9

Abstract: The crystalline -MnO and -MnO nanorods have been successfully prepared via a facile hydrothermal method from -MnOOH nanorods precursor, respectively. The samples were characterized by means of X-ray diff raction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), field emission scanning electron microscope (FESEM) and Fourier transformed infrared spectra (FTIR). The morphology and structure of -MnOOH nanorods precursors have a great influence on the crystal structure of the obtained products. The -MnO nanorods are prepared from the 100°C -MnOOH precursor, while the -MnO nanorods are obtained from the 150°C -MnOOH precursor, respectively. Besides, the catalytic activity of the prepared -MnO and -MnO nanorods for the HO decomposition has been investigated comparatively, and the latter shows better catalytic activity.
