Porous single-crystalline nanosheet (NS) arrays of Co3S4 have been synthesized via a simple shape and phase transformation route, which exhibits high specific capacitance (1081 F g−1 at 1.61 A g−1) areal (2.69 cm−2 4 mA 2.33 12 cm−2) with good cycling performance (96.2% retention after 3000 cycles).
Abstract Although lithium (Li) is inert to dry oxygen at room temperature, it reacts with elevated temperatures, causing thermal runaway and fire hazard in Li metal batteries (LMBs). However, the oxidation mechanism of high temperatures not explored. Here, real‐time transmission electron microscopy studies effect temperature on mechanisms dendrites are reported. The controlled by outward diffusion + through oxide layer (the Wagner mechanism), forming thin films 2 O comprising nanograins...
TiNiSi-type Zintl phase CaAgSb can transform into LiGaGe-type CaAg x Zn(1-x)/2Sb when some of the Ag atoms are substituted by Zn atoms, leading to an ultralow thermal conductivity ≈0.4 W m-1 K-1 in whole measured temperature range CaAg0.2Zn0.4Sb. The microstructure is then investigated spherical aberration-corrected electron microscopy on atomic scale, which reveals all-scale hierarchical structure that scatter phonons a wide frequency range. There exist large quantity nanometer precipitates...
Using scanning transmission electron microscopy, we report direct observation of oxygen vacancy ordering induced atomic displacements the cation sub-lattice in yttria-stabilized zirconia (YSZ). We find that lattice adopts a zigzag configuration along [100] direction with alternately narrow and wide spacings equivalent 0.85 1.15 times (200) inter-planar distance cubic YSZ. atomistic simulations, show are by alternate presence vacancies at (1/4, 1/4, 1/4) 3/4, sites unit cells [001] direction....
The crystal structures and morphologies of ternary Bi2(SexTe1−x)3 nanoplates have been systematically characterized by employing atomic force microscopy, scanning electron high-resolution transmission microscopy equipped with the energy dispersive X-ray spectrometer, diffraction. We find that exhibit uniform charge surface potential distributions. And their Fermi levels can be effectively tuned up to 0.23 eV varying selenium/tellurium composition ratios.
The microscopic mechanisms of the initial-stage oxidation Ni3Al(100) and Ni3Al(110) surfaces are comparatively studied using ab initio calculations based on density-functional theory thermodynamics considerations. surface energies two as functions aluminum oxygen chemical potentials constructed show that formation any antisite defects is not favorable at surface, whereas Al surface. phase diagrams -(110) with different various coverages determined. These results adsorption enhances...
