International Journal of Electrochemical Science, 2019 The Belousov-Zhabotinskii (BZ) oscillating reaction mixture (malonic acid, bromate, and cerium ions in a strongly acidic medium) was studied. The oxidation state of the Ce+4/Ce+3 catalyst fluctuates and drives the open-circuit potential (OCP) of the ...

Dissipative Structures in Supersonic Turbulence
Physical Review Letters, 2009 We show that density-weighted moments of the dissipation rate, $ε_l$, averaged over a scale $l$, in supersonic turbulence can be successfully explained by the She and Lévêque model [Phys. Rev. Lett. {\bf 72}, 336 (1994)]. A general method is developed to measure the two parameters of the model, $γ$ and $d$, based directly on their physical ...

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Conditins for the Time Dissipative Structure Formation at Nonequilibrium Transitions [PDF]
Журнал нано- та електронної фізики, 2011 We discuss processes of the dissipative structure formation when the nonequilibrium phase transition takes place. The model is considered under assumptions that dispersion of the relaxation time of the order parameter and influence of the external force ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
