This paper provides the analytical solution to a one-parameter Šesták–Berggren kinetic model for thermoanalytical study of pyrolysis reactions involving multiple independent parallel reactions. Such are widely used, instance, in modeling thermal protection materials used heatshields spacecraft during atmospheric entry phase. Solving inverse problems infer parameters through optimization techniq...

The hot deformation behavior of a Fe–22Cr–25Ni–3.5W–3Cu–1.5Co super-austenitic stainless steel was investigated using isothermal compression tests with a wide range of temperatures (1173–1373 K) and strain rates (0.1–10 s). The results showed that all the flow curves gradually turned to balanced stress state without notable peak stress characteristics during the entire deformation, which indica...

We consider the effect of the reversibility of the chemical reaction on the propagation and stability of laminar premixed flames, an important realistic aspect which has received little attention in the literature. For the sake of analytical tractability and clarity of the results, the thermodiffusive approximation of constant density is adopted, along with the simple framework of a single reve...

Machine learning techniques have been used to quantify the relationship between local structural features and variations in dynamical activity disordered glass-forming materials. To date these methods applied an array of standard (Arrhenius super-Arrhenius) glass formers, where work on "soft spots" indicates a connection linear vibrational response configuration energy barriers non-linear defor...

We have studied a system composed of an hydrophobic aerosil (R812) dispersed in the liquid crystal 4-n-octyl-4’-cyanobiphenyl (8CB) using the spin probe ESR technique and, in particular, we have determined, for different aerosil concentrations, the temperature dependence of the orientational order parameter 〈P2〉 and the rotational diffusion coefficient D⊥ of the probe 5-doxyl stearic acid in th...
