Analysis of structure formation processes features in high-entropy alloys of Al-Co-Cr-Fe-Ni system during laser alloying

Results in Materials, 2022
Using the time dependent nucleation theory, the temperature dependences of the heterogeneous nucleation time for multicomponent substitution solid solutions, the formation of which is typical for high-entropy alloys in Al–Co–Cr–Fe–Ni systems obtained by ...

Synthesis and phase stability of zirconia-lanthania-ytterbia-yttria nanoparticles; a promising advanced TBC material

Journal of Asian Ceramic Societies, 2020
Advanced thermal barrier coatings (TBCs) developed by incorporating multicomponent rare earth oxide dopants into zirconia are promising alternative to replace yttria-stabilized zirconia (YSZ) thermal barrier coatings.

Comparison between solution‐phase stability and gas‐phase kinetic stability of oligodeoxynucleotide duplexes [PDF]

Journal of Mass Spectrometry, 2001
AbstractThe relative kinetic stabilities of different 16‐mer oligonucleotide duplexes were investigated by source collision‐induced dissociation (CID) in a heated capillary electrospray ion source. They were compared with the relative stabilities in solution obtained by thermal denaturation monitored by UV spectrophotometry.

An improved reduction method for phase stability testing in the single-phase region

Open Chemistry, 2020
A new reduction method for mixture phase stability testing is proposed, consisting in Newton iterations with a particular set of independent variables and residual functions. The dimension of the problem does not depend on the number of components but on

Stability of phase-contrast tomography

Journal of the Optical Society of America A, 2007
Phase-contrast tomography (PCT) allows three-dimensional imaging of objects that display insufficient contrast for conventional absorption-based tomography. We prove that PCT is stable with respect to high-frequency noise in experimental phase-contrast data, unlike conventional tomography, which is known to be mildly unstable.

Thermodynamic geometry of black holes in f(R) gravity [PDF]

, 2016
In this paper, we consider three types (static, static charged and rotating charged) of black holes in f(R) gravity. We study the thermodynamical behavior, stability conditions and phase transition of these black holes.

Decreasing viscosity and increasing accessible load by replacing classical diluents with a hydrotrope in liquid–liquid extraction

Frontiers in Chemical Engineering
Using a generic example, we show that the strategy of replacing a classically used aliphatic diluent with a hydrotrope in liquid–liquid extraction induces higher performance.
