CrNbTaVWx with (x = 1 and 1.7) high entropy alloys have been devised for thermal barriers between the plasma-facing tungsten tiles copper-based heat sink in first wall of fusion nuclear reactors. These novel materials were prepared by ball milling consolidated Upgrade Field Assisted Sintering Technology at 1873 K under an applied pressure 90 MPa 10 min. In this work, structural mechanical prope...

The origin of the catalytic power of enzymes with a meta-stable native state, e.g. molten globular state, is an unsolved challenging issue in biochemistry. To help understand the possible differences between this special class of enzymes and the typical ones, we report here computer simulations of the catalysis of both the well-folded wild-type and the molten globular mutant of chorismate mutas...

Refractory high-entropy alloys are considered as potential structural materials for elevated temperature applications. To obtain refractory with high strength, different amounts of Si were added into the NbMoTiVW alloys. The effects on phase constitution, microstructure characteristics and mechanical properties NbMoTiVWSix investigated. Results show that when addition is 0, 0.025 0.05 (molar ra...

At its origins, thermodynamics was the study of heat and engines. Carnot transformed it into a scientific discipline by explaining engine power in terms of transfer of “caloric”. That idea became the second law of thermodynamics when Thomson and Clausius reconciled Carnot’s theory with Joule’s conflicting thesis that power was derived from the consumption of heat, which was determined to be a f...

Recurrence plots were introduced to quantify the recurrence properties of chaotic dynamics. Hereafter, the recurrence quantification analysis was introduced to transform graphical interpretations into statistical analysis. In this spirit, a new definition for the Shannon entropy was recently introduced in order to have a measure correlated with the largest Lyapunov exponent. Recurrence plots an...

The statistical origin of the entropy of charged black holes in models of induced Einstein-Maxwell gravity is investigated. The constituents inducing the EinsteinMaxwell action are charged and interact with an external gauge potential. This new feature, however, does not change divergences of the statistical-mechanical entropy of the constituents near the horizon. It is demonstrated that the me...
