Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

open access: yesAdvanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

open access: yesAdvanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

Irregular Migration – Between Legal Status and Social Practices: 'Narratives of Polish labour migration'

open access: yesNordic Journal of Migration Research, 2012
How do Polish migrant workers experience the process of migration and how does irregular migration status influence their life plans? In this article I analyse how the shifts between different legal statuses may be related to the social practices ...

“Irregular” Migration and Divergent Understandings of Security in the Sahel [PDF]

open access: yes, 2020
On 23 September 2020, the EU launched its new Pact on Migration and Asylum. In a refreshingly blunt press-release accompanying the Pact one could read: “The current system no longer works. And for the past five years, the EU has not been able to fix it”.

Linking Polyelectrolyte Modification and Enzyme‐Catalyzed Phenolic Acid Functionalization of Cellulose Fiber for Functional Foams

open access: yesAdvanced Materials Technologies, EarlyView.
Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing
