in the composition from the average value was calculated as the ratio of the local elemental concentration to its average concentration. Metallographic samples were etched with Marble’s reagent for 1 min......
(0.15,0.4)CrFeNiCo HEA at 600 °C under 25 MPa pressure for 70 h enabled dominant spinel oxide formation [54]. The increased Al ratio enhanced the oxidation resistance thanks to the sluggish......
was observed with an mole ratio of 39.94% in Fig. 12(d), confirming the Ag-GNS reinforcement in the matrices. Furthermore, the dislocation density between the Ag-GNSs and the solder matrix can......
] Shoulder-to-pin diameter ratio (SPR) defines the relation between the dimensions of tool pin and shoulder. SPR of dissimilar FSW of Al-Cu depends on the alloy type and the thickness of the workpiece... of dissimilar Al-Cu Weld joint efficiency (η), is a criterion to identify the acceptable weld joint and it is expressed as the ratio of weld tensile strength to the workpiece tensile strength. During......

engineering, the perovskite MAPbI3-xClx prepared by spin-coating of MAI and PbCl2 (3:1 molar ratio) in a DMF solution was utilized as the photoactive layer of inverted PSCs, delivering the PCE up to 10...%. Furthermore, by adjusting the composition of DMF and GBL mixed solvents, the largest MAPbI3-xClx crystal grains at a 8:2 volume ratio of DMF:GBL were obtained via spray coating due to the flux balance......
structure. An interesting feature is that the first-order magnetic phase transition (FOMT) temperature in Gd5(Si1-xGex)4 is strongly dependent on the molar ratio Si to Ge, as shown in Fig.4 [4......
principle as (4) The mass action concentration of structural unit is defined as a ratio of equilibrium mole number of structural unit i to the total equilibrium mole......
