Hierarchical nanorods constructed by Mn2Mo3O8@reduced graphene oxide nanosheet arrays with enhanced lithium storage properties

Submicron‐sized Sb 2 O 3 with hierarchical structure as high‐performance anodes for Na‐ion storage

“…The FESEM and TEM images of the Sb 2 O 3 product in Figure display that the sample is composed of uniform secondary particles with size in submicron ranges, which is aggregated from primary nanoparticles with average size of approximately 80 nm. Such a hierarchically structure not only possesses the good permeability and short diffusion length enabled by nano‐sized effects but also gain the advantage of high volumetric energy density and Coulombic efficiency originated from the high tap density and small surface area of the submicron‐sized secondary particles. Sb 2 O 3 polycrystalline nanoparticles feature leads to diffraction rings in the selected‐area electron diffraction (SAED) pattern (inset of Figure B).…”

A strategy of using temporary space-holders to increase the capacity for Li S batteries

“…9b) after cycling test. The new semicircle corresponds to SEI film resistance (R2) [68,69]. 96 Ω for MMMPC-rGO/S, MPC-rGO/S electrodes, respectively.…”

Grain engineered polar-axis-oriented epitaxial Mn2Mo3O8 films with enhanced magnetic transition temperature

“…2,4 The magnetic properties of M 2 Mo 3 O 8 can be controlled by manipulating the external magnetic field, electric field, and temperature. 1,2,5 In addition to powders and bulk single crystals, 4,[6][7][8][9][10][11] epitaxial M 2 Mo 3 O 8 films for M = Mn have been prepared on Al 2 O 3 (001) substrates using pulsed laser deposition (PLD). 12 Tensilestrained Mn 2 Mo 3 O 8 (hereafter MMO) films exhibit a larger spontaneous magnetization and polarization and a higher Ne ´el temperature (T N ) than bulk single crystals, 4,12 demonstrating that strain engineering is a promising way to modify the ferroic properties of MMO films.…”
