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.

Crystallization kinetics of GdYScAlCo high-entropy bulk metallic glass

Chimica Techno Acta, 2023
The thermal stability and non-isothermal crystallization of a new bulk-amorphous high-entropy (HE-BMG) equiatomic GdYScAlCo alloy were studied by differential scanning calorimetry (DSC). The alloy shows a four-stage crystallization process.

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 ...
