On the theoretical side, ab initio electronic structure calculations of Fe/MgO13 and Au/Fe/MgO14 junctions with in-plane lattice constants of Fe and MgO, respectively, found a linear VCMA with β of about +130 and +70 fJ V−1m−1, respectively. A ubiquitous feature in ...
The thermal conductivity K(T) vs temperature has been measured for (Y,Pr)Ba 2 Cu 3 O 7 , (Y,Tb)Ba 2 Cu 3 O 7 and YBa 2 (Cu,Zn) 3 O 7 single crystals from... PF Henning,G Cao,JE Crow,... - 《Journal of Superconductivity》 被引量: 9发表: 1995年 ...
Lattice structure and slip systems are introduced as well as the main mechanical properties of MgO based on constant strain-rate and creep experiments. In Section 3, we focus on multi-scale modeling of MgO plasticity. This section relies on atomic scale simulations (dislocation core modeling) and...
However, the optimal lattice constants of the RS ZMO models obviously decrease, as shown in Figure 2a. Nevertheless, the Hubbard U parameter is helpful for improving the underestimated 𝐸𝑔Eg. However, the on-site Coulomb interactions of the p and d localized electrons also induce the ...
Ni catalysts based on Al2O3 and Al2O3 modified with CaO-MgO were tested for the dry reforming of biogas (BDR). Time-on-stream experiments were carried out between 600 and 800 °C, and the spent catalysts were examined using a variety of characterization techniques including, N2 adsorption...
Entropy generation due to heat transfer accumulates around the upper cold wall and increases in the lower-left corner with increasing values of Ra, due to increased kinetic energy and due to a decrease in the velocity near the boundary layer; however, for values of Ra ≤ 104, the entropy ge...
They also used Na2O, CaO, and K2O as carrier material. The methanation reaction with 5% Ru_10% MgO/Al2O3 catalysts was performed in a packed-bed reactor at a temperature of 593 K and atmospheric pressure. The feed flow rate was 30 mL min−1 (CO2/N2 = 10:90) plus 30 mL min...
As long as the complete system, based on a Li2O-Al2O3-SiO2-CaO mixture, does not contain any other element, the results are promising. As soon as other elements are added, new phases start to crystallize. Besides Li and Al, reporting from the Li-ion battery input into the slag, Si,...
