Table 2: Entropies of some solid elements at 298 K, J K–1 mol–1 The entropies of the solid elements are strongly influenced by the manner in which the atoms are bound to one another. The contrast between diamond and graphite is particularly striking; graphite, which is built up of lo...
CrCoNi alloy exhibits a remarkable combination of strength and plastic deformation, even superior to the CrMnFeCoNi high-entropy alloy. We connect the magnetic and mechanical properties of CrCoNi, via a magnetically tunable phase transformation. While both alloys crystallize as single-phase face-centered...
2,3. Except for the computational discovery of high-entropy carbides, performed with the entropy-forming-ability descriptor4, most innovation has been slowly driven by experimental means1,2,3. Hence, advancement in the field needs more theoretical contributions. Here we introduce...
High entropy alloys have been proposed in 2004, which are expected to be widely used in aerospace, petrochemical and other fields due to their excellent properties compared with the traditional alloys, and have become a hot spot in current metal material research. It has become one of the metho...

C(graphite) arrow C(diamond) Using the information below, calculate the standard entropy change for the reaction below. C6H12O6 (s) + 6 O2 (g) --> 6 CO2 (g) + 6 H2O (l) Substance S degree (J/mol-K) C6H12O6 (s) 212.13 O2 ...
The ingots of the above samples were prepared by vacuum melting at 1373 K for 24 h, which were separately ground into fine powders and loaded into a graphite mold with an inner diameter of 16 mm. Then, a dense disk sample was prepared by a spark plasma Crystal structure and microstructure...
For a monotonically increasing R m flow ratio, the position of the G-peak is downshifted to a low wavenumber, a decrease in I D /I G ratio suggests a decrease in sp 2 /sp 3 ratio, which is associated with the decrease in the fraction of graphite and the more disordered carbon ...
However, commonality of superconducting characteristics of HEA materials is unclear. Here, we have investigated the crystal and electronic structure, and the robustness of superconducting states in a HEA-type metal telluride (MTe; M = Ag, In, Sn, Pb, Bi) under high pressure, and the ...
whereas the additional peaks for remaining three compositions indicate the presence of secondary phases. The small peaks at 2θ = 31.7°, marked by the diamond symbol in the spectra of HfNbTaTiZrC5, HfNbTaTiWC5and HfTaTiWZrC5, are from the (111) plane of a monoclinic (Hf,Zr)O2phase...
