3D printed polyethylene terephthalate glycol ternary composites with short carbon fiber/ carbon nanotube graphitic reinforcements: Insights into multi-scale synergistic mechanisms

Composites Part C: Open Access
Three-dimensional printed (3DP) Polyethylene Terephthalate Glycol (PETG) ternary composites reinforced with short carbon fibers (sCF) and multi-walled carbon nanotubes (CNT) are reported for the first time. A single-screw extrusion process is employed to

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

Assessment of Different Technologies in the Fabrication of 3D Printed Tooth Models for Dental Education

European Journal of Dental Education, EarlyView.
ABSTRACT Background 3D printing has emerged as a practical method for fabricating customisable, accurate and affordable dental training models. Numerous 3D printing technologies exist, though there is no standardised comparison to inform their implementation in dental education.

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

Medical and Veterinary Entomology, EarlyView.
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.

A Dual Cell‐Line Molecular Platform to Assess Sub‐Threshold Biocompatibility: Application to Processed Orthodontic Clears Aligners

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective Traditional biocompatibility assessments primarily address cytotoxicity and bulk material properties but often overlook molecular responses that occur below toxicity thresholds. Detecting these subtle effects is crucial for materials intended for prolonged contact with human tissues.

Dental Arch Expansion With In‐House Clear Aligners: An Exploratory Prospective Clinical Study on Torque, Vertical Control and Attachment Configuration

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective To evaluate the short‐term efficacy of transverse dental arch expansion with in‐house aligners (IHA) by comparing planned and achieved buccolingual movements, and secondarily to explore torque expression, vertical control and the influence of attachment design/position using a contralateral within‐subject approach.

FieldDino: Rapid In‐Field Stomatal Anatomy and Physiology Phenotyping

Plant, Cell &Environment, EarlyView.
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.
