Crystallization kinetics of overlapping phases in Se70Te15Sb15 using isoconversional methods

Progress in Natural Science: Materials International, 2015
AbstractThe crystallization kinetics of Se70Te15Sb15 chalcogenide glass was studied by Differential Scanning Calorimetry (DSC) under non-isothermal conditions. This glass was found to have a double glass transition and double overlapped crystalline phases. The overlapped crystalline phases were successfully separated using the Gaussian fit model.

Thermo‐Oxidative Stability of Materials: Assessment and Predictions

Chemistry–Methods, Volume 6, Issue 3, March 2026.
The article summarizes long‐term stability predictions based on non‐Arrhenian extrapolation of fast high‐temperature thermoanalytical measurements. The theory is applicable for the lifetime estimation of objects made of plastics and other organic materials which can be employed in the conservation of plastic artifacts.

Naphthalene‐Modified Cationic Initiators for Superior Polymerization Stability and Thermal Conductivity in Epoxy Thermosets

Small Science, Volume 6, Issue 3, March 2026.
Naphthalene‐modified cationic initiators extend epoxy curing time, preserving intrinsic LC ordering and achieving exceptionally high thermal conductivity of 0.86 W m−1 K−1 in unfilled networks. Incorporating thermally conductive fillers further boosts performance, yielding composite conductivities up to ~25 W m−1 K−1.

Investigating Chemical Modifications in Furan‐Based Polyesters Through Experimental and Mathematical Analysis

Macromolecular Materials and Engineering, Volume 311, Issue 1, January 2026.
PTT‐co‐PTG and PTF‐co‐PTG copolyesters were synthesized via melt polycondensation. Phase‐transition analysis exhibited similar glass‐transition temperatures (Tg) for petrochemical and renewable feedstocks. The Gordon–Taylor model best fit experimental Tg across the copolymers composition range, validating its use for copolymer design and property ...
