Accelerated degradation testing impacts the degradation processes in 3D printed amorphous PLLA

L. Malone, Serena M. Best, Ruth E. Cameron

Additive manufacturing and electrospinning are widely used to create degradable biomedical components. This work presents important new data showing that the temperature used in accelerated tests has a significant impact on the degradation process in amorphous 3D printed poly-l-lactic acid (PLLA) fibres. …

Induced Birefringence in 3D Printing: Concealing Information Optically within Printed Objects

David M. Roper, Kyung‐Ah Kwon, L. Malone, Serena M. Best et autres

Abstract This paper presents a novel method to spatially vary the intra‐layer birefringence of Fused Filament Fabricated (FFF) parts by controlling chain alignment during extrusion along individual rasters. The role of print speed, extrusion factor and layer separation on the birefringence of …

Thawing of massive ground ice in mega slumps drives increases in stream sediment and solute flux across a range of watershed scales

Steven V. Kokelj, Denis Lacelle, Trevor C. Lantz, Jon Tunnicliffe et autres

Abstract Ice‐cored permafrost landscapes are highly sensitive to disturbance and have the potential to undergo dramatic geomorphic transformations in response to climate change. The acceleration of thermokarst activity in the lower Mackenzie and Peel River watersheds of northwestern Canada has led to …
