Natural physical aging in glassy As–Se: A comparative study of chaotic behavior with enhanced results analysis

Chaotic behavior of light-assisted physical aging in arsenoselenide glasses

“…[23][24][25][26][27][28] Amorphous state of glassy bulks were controlled visually by a characteristic conch-like fracture, as well as data of X-ray diffractometry.…”

“…[20][21][22] Recently, such an approach has been adequately applied to describe kinetics of natural PhA revealed in structural relaxation of Se-rich As-Se glasses below glass transition T g . 23 Kinetics of enthalpy losses DH induced by prolonged storage in natural ambient conditions was used to determine the phase space reconstruction parameters, the emerged chaoticity was attributed to complex nature of underlying structural transformations initialized by multiply repeated mixed serial-parallel cycles of Se atoms twisting within doublewell potentials of nearest chemical neighbours (aligning of Se chains) followed by atomic shrinkage at larger length scales. [24][25][26][27][28] In the present paper, this approach has been applied to disclose deterministic chaoticity in the kinetics of enthalpy losses in As-Se ChG under prolonged exposure by light of different discrete wavelengths.…”

Analysis on Phase Space Reconstruction and Chaotic Characteristic of Element Concentration Series of Gold Deposit

“…Therefore, investigation in the oreforming process with solid phase and the effect of dynamics has great significance. Chaos theory is an important branch of nonlinear analysis, and is widely applied in the last few decades in a variety of systems, e.g., mechanical, chemical, physical, as well as in social sciences [7][8][9][10]. In particular, chaotic techniques, developed to extract qualitative and quantitative information from time series, have been applied recently to the study of a large variety of irregular, erratic signals and by now have demonstrated to can be very useful to reveal deep dynamical features [11].…”

Investigation of physical ageing effect in Se 90 In 4 Sn 6 glass

“…In general, the relaxation process within the amorphous phase has several features that lack a complete explanation: the reason is of threefold: (1) in most cases, the relaxation process is non-Arrhenius in its temperature dependence; (2) it is non-exponential in its time dependence; (3) it is non-linear in its structural state dependence (Hodge, 1994). Therefore, wide door for studying of physical ageing in chalcogenide glasses is still open and nowadays research focus has been shifted towards new interpretation of this phenomenon using new techniques and new theories (Shpotyuk et al, 2013;Hacinliyan et al, 2014;Balitska et al, 2014;Shpotyuk et al, 2014).…”

“…So, the causes of ageing in living systems are one of the greatest unsolved mysteries in science (Chakravarty et al, 2005). The effect of natural physical ageing, which tends non-crystalline materials towards more favorable thermodynamic states, is able to modify some other phenomena in these disordered solids (Hacinliyan et al, 2014). The physical ageing of a glassy polymer occurs at a temperature below the glass transition temperature with time-dependent changes in specific volume, enthalpy, mechanical strength, and dielectric responses (Hutchinson, 1995).…”
