Influence of Annealing Temperature on the Thermomechanical Properties and Dimensional Stability of FFF‐Printed PET‐CF

Journal of Applied Polymer Science, Volume 143, Issue 38, October 10, 2026.
Following extrusion at 265°C, components underwent a 45‐min annealing process at temperatures from 145°C to 225°C. The results show that increasing the annealing temperature elevates the onset of thermal softening, significantly enhancing thermal reliability.

Some thermodynamic and kinetic properties of the system PETG‐CO₂, and morphological characteristics of the CO₂‐blown PETG foams

Polymer Engineering & Science, 1999
AbstractThe solubility of CO2 in PETG, a glycol‐modified PET, was measured at different temperatures and over a broad pressure range, and diffusion coefficients were derived at the corresponding conditions. The solubility of CO2 is quits high. For example, almost 15 wt% CO2 can be dissolved in PETG at 35°C and 6.0 MPa. Consequently, CO2 is good blowing

Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

Advanced Robotics Research, Volume 2, Issue 5, October 2026.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

The Complete Chloroplast Genome of Dioscorea hypoglauca: Comparative Genomics and Phylogenetic Insights

Ecology and Evolution, Volume 16, Issue 10, October 2026.
We assembled and characterized the complete chloroplast genome of Dioscorea hypoglauca, a medicinally important yam species from southern China. The 153,219 bp genome exhibits a typical quadripartite structure, containing 129 genes (84 protein‐coding, 37 tRNA, and 8 rRNA genes), and comparative analyses with 22 other Dioscorea species revealed dynamic ...
