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

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.

A Novel Distributed Sensor Network to Assess Wind Turbine Blade Acoustics for Structural Health Monitoring

Wind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT To reduce the need for scheduled wind turbine blade inspections and large‐scale repairs, a novel distributed acoustic sensing system for monitoring the structural health of wind turbine blades is proposed. This integral passive monitoring system utilizes a sparse array of in‐blade multimodal sensors and a single blade‐external downtower sensor,

FieldDino: Rapid In‐Field Stomatal Anatomy and Physiology Phenotyping

Plant, Cell &Environment, Volume 49, Issue 10, Page 7714-7726, October 2026.
ABSTRACT Stomatal anatomy and physiology define CO2 availability for photosynthesis and regulate plant water use. Despite being key drivers of yield and dynamic responsiveness to abiotic stresses, conventional measurement techniques of stomatal traits are laborious and slow, limiting adoption in plant breeding.

Conspecific cueing or cooperative feeding?—Foraging stable flies are visually attracted to conspecific flies

Medical and Veterinary Entomology, Volume 40, Issue 3, Page 512-529, September 2026.
In two‐choice laboratory bioassays, food‐deprived and CO2‐stimulated stable flies were offered paired landing platforms that were baited or not (control) with conspecific flies. The presence of conspecifics prompted the attraction and landing of foraging stable flies.
