Phase transitions in the Co-rich part of Co–Al–Nb–Mo phase diagram are studied by energy dispersive spectroscopy (EDS), X-ray analysis, transmission electron microscopy (TEM), and differential scanning calorimetry (DSC) measurements. The obtained results were compared with for alloys binary Co–Al ternary Co–Al–Nb, Co–Al–Mo systems. Formation intermetallic L12 structure was found a range 10 at.%...

New resolving bases for ibuprofen 1 and mandelic acid 2 were studied and qualified by their binary phase diagrams of the corresponding salts. It was shown that analysis of the binary phase diagrams gives a good prediction for a resolution process. A comparison of resolving bases revealed that (S)-phenylglycinol (S)-7 is the best resolving base for ibuprofen 1. By the same procedure, various res...

in recent years, it has become increasingly important to incorporate explicit dynamics in economic analysis. these two tools that mathematicians have developed, differential equations and optimal control theory, are probably the most basic for economists to analyze dynamic problems. in this paper i will consider the linear differential equations on the plane (phase diagram) and elements of nonl...

Piezoelectric polymers have emerged as promising materials for application in pressure sensing devices particular wearable applications, where inorganic piezoelectric can face limitations due to their brittleness. One of the bottlenecks adaptation is relatively weak voltage coefficient. Hence there been numerous efforts improve performance comprising by making composites poly(vinylidene fluorid...

High-entropy (H-E) alloys, bulk metallic glasses (BMGs) and high-entropy BMGs (HE-BMGs) were statistically analyzed with the help of a database of ternary amorphous alloys. Thermodynamic quantities corresponding to heat of mixing and atomic size differences were calculated as a function of composition of the multicomponent alloys. Actual calculations were performed for configurational entropy (...

In this work, a series of compounds in the CaO-CoOx-ErOy ternary oxide system were synthesized air at 885 °C, using high temperature solid-phase synthesis method. The phase boundary each solid solution region was determined by X-ray powder diffraction techniques. diagram °C includes three solutions: (Ca3−xErx)Co4O9−z (0 ≤ x 0.9), (Ca3−xErx)Co2O6−z 1.25), and (Er1−xCax)CoO3−z 0.33). Four three-p...
