Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

Packaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

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.

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.
