The electron energy was considered self-consistent for energy variation lower than 10−6 eV. Geometric optimization was considered to converge when the energy variation was <0.05 eV Å−1. In the direction perpendicular to the structural plane, the corresponding vacuum spacing was 15...
The long-term cyclability of KVO towards K-ion storage was tested in a symmetric full-cell configuration in a 3 M KCl electrolyte at various current densities ranging from 2 to 20 A g−1.Figure 2dshows the nearly linear potential-capacity curves. The calculated electrode capacities are...
it nevertheless remains below the limits of detection for virtually all traditional spectroscopies. Furthermore, binding of numerous other metals and the absence of any long-range ordering impede x-ray/neutron scattering approaches. However, XAFS is devoid of such sample form limitations and simultaneou...
Transmission electron microscopy(TEM) was used to investigate the particle size, distribution, morphology and composition of microalloyed carbonitrides precipitated in test steels at 930掳C and 700掳C. The relation between pattern and configuration was revealed, and the results indicated that the ...
graphene fluoride, or graphene oxide sheet embracing said particulate, and wherein said particulate has an electrical conductivity no less than 10−4 S/cm and wherein said multiple composite particulates are packed together with graphene sheets forming a three-dimensional electron-conducting pathway. ...
Due to their good wetting properties, the compounds of formula I typically form uniform continuous liquid films on substrates. After hydrolysis/thermolysis and, if desired, annealing, they are converted into thin uniform metal oxide films. Adhesion of the films to the substrate may depend on the ...
9): (a) photoresist is spin-coated and deposited on a substrate using photolithography to form the pattered VO2 bricks; (b) a desired sample pattern is transferred to photoresist by writing the pattern with an electron beam lithography; (c) 1 μm thick VO2 layer is then prepared on 38...
Vanadium pentoxide (α-V2O5) is one of the most widely studied layer-VOs because of its facile synthesis, low cost, and high theoretical specific capacity of 589 mAh g−1based on the two-electron reaction43. In AZIBs, however, α-V2O5is known to require long activation cycles, making it...

(KTP)-type structure built upon helical chains of corner-shared VO4F2octahedra linked by PO4tetrahedra through vertexes to form a robust framework (Fig.1e) that encloses a 3D system of intersecting cavities accommodating Na+ions. The unit cell volume is ~2.2% and ~4.4% smaller than that ...
