Článekpeer-reviewedpublished Otevřený přístup Thermomechanical analysis as a useful tool to study photoinduced changes of the viscous flow of glassy materials(University of Pardubice, 2021) Smolík, Jan; Zmrhalová, Zuzana; Knotek, Petr; Černošková, Eva; Plecháček, Tomáš; Adam, MartinA modified thermomechanical analyzer is described as an useful tool to study the photoinduced changes in the viscous flow and thermal properties of glassy materials. The device proposed was tested on model chalcogenide glass As2S3 using the penetration method. Further, the article discusses and summarizes the effect of the light illumination (at wavelength of 650 nm) on the viscous flow at different temperatures below the glass transition temperature (Tg), and on the thermal behaviour interpreted from dilatometric curves via glass transition temperature and softening temperature.Článekpeer-reviewedpublished Otevřený přístup Effect of silver addition on thermal properties of (GeS2)50(Sb2S3)50 glass(University of Pardubice, 2021) Včeláková, Michaela; Košťál, Petr; Honcová, Pavla; Adam, MartinThermal properties of the (GeS2)50(Sb2S3)50 glass without and with the addition of 10 at. % of silver has been studied using calorimetry and thermal analysis. The viscosity data were obtained in a wide temperature range and described by the appropriate model. The glass transition region and the crystallization behaviour were studied in detail.
