Circularity in 3D Printing with Poly(Ethylene Terephthalate Glycol): Copolymer Composition Dependent Degradation During Recycling

Macromolecular Materials and Engineering
Reduced environmental impact is commonly cited as a driver for additive manufacturing, but non‐circular end‐of‐life disposition of the printed materials reduces these advantages.

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 ...

Organellar inheritance in the green lineage: insights from Ostreococcus tauri [PDF]

, 2013
Along the green lineage (Chlorophyta and Streptophyta), mitochondria and chloroplast are mainly uniparentally transmitted and their evolution is thus clonal. The mode of organellar inheritance in their ancestor is less certain.

Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

Journal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

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.

The phenotypic equilibrium of cancer cells: From average-level stability to path-wise convergence

, 2015
The phenotypic equilibrium, i.e. heterogeneous population of cancer cells tending to a fixed equilibrium of phenotypic proportions, has received much attention in cancer biology very recently.
