Low Frequency Mechanical Spectroscopy Study of Three Pyrrolidinium Based Ionic Liquids

open access: yesArchives of Metallurgy and Materials, 2015
In this work we present our recent results on three ionic liquids (ILs), which share bis(trifluoromethanesulfonyl)imide (TFSI) as anion and have different pyrrolidinium based cations.

Kinetics of thermal decomposition of sodium hexafluorosilicate under isothermal conditions

open access: yesВесці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук
The results of an experimental study of the thermal decomposition of sodium hexafluorosilicate Na2SiF6, performed under isothermal conditions at temperatures of 600, 700, 800 and 900 °C, are discussed. It is shown that the kinetics of this process can be

Advanced avrami formula and its application to describing the isothermal crystallisation of polymers

open access: yes
The classic Avrami formula has widely been used to describe and characterize the crystallisation process of polymers. We showed that the Avrami formula is not correct for the random nucleation.

Crystallization Behavior of a Ferri-Silicate α-Waste Glass

open access: yes, 1985
The crystallization behavior of a ferri-silicate α-waste glass was studied by means of several experimental techniques. The main crystal phase showed a plate-like morphology and was identified as a monoclinic pyroxene.

Application of a Numerical Method for the Analysis of Metglas 2826 MB Crystallization Kinetics [PDF]

open access: yes, 2002
Crystallization kinetics of y-FeNiMo solid solution in Metglas 2826 MB was studied by isothermal differential scanning calorimetry (DSC). The Johnson-Mehl-Avrami (JMA) equation was used to describe the crystallization process.
