Effects of Y2O3 on crystallization kinetics of SiO2-Al2O3-CaO-CaF2 oxy-fluoride glass-ceramic system

open access: yesResults in Physics, 2017
Differential thermal analysis (DTA) patterns of SiO2-Al2O3-CaO-CaF2 oxy-fluoride glass system with adding different amounts of Y2O3 from 0.5 (wt%) to 1.5 (wt%) have been studied under isochronal circumstances. It is concluded that, the crystallization of

Geopolymers as a Sustainable Chemical Platform: From Building Materials to Advanced Functional Applications

open access: yesThe Chemical Record, Volume 26, Issue 9, September 2026.
Geopolymers are presented as a chemically programmable platform whose properties emerge from activation chemistry, nanoscale disorder, and interfacial design. The review highlights sustainability challenges, the shift toward nanoengineered and hybrid systems, and the rise of halloysite‐based architectures enabling tunable structures across scales for ...

Classification of Processes by the Lyapunov exponent [PDF]

open access: yes
This paper deals with the problem of the discrimination between wellpredictable and not-well-predictable time series. One criterion for the separation is given by the size of the Lyapunov exponent, which was originally defined for deterministic systems ...

Crystallization kinetics of Zr-33 at % Ni amorphous alloy

open access: yes, 1986
The amorphous to crystalline transition in Zr-33 at% Ni amorphous alloy has been found to occur by polymorphic crystallization. The product of the cyrstallization process has been identified as the equilibrium Zr2Ni intermetallic phase.
