Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

Hidden costs and propped-up profits: unraveling the economics of Europe’s purse-seine tuna fishing industry

npj Ocean Sustainability
Despite tuna fisheries’ global economic significance and contributions to food security and trade, we find that without substantial subsidies, notably fuel tax exemptions and fishing access agreement fees supported by public funds from the European Union,

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Bloom

, 2023
This essay tracks the solar relations embedded in the short and long phosphorous cycle, tracking the bodies, bonds, and supply chains that connect its extraction in the occupied Western Sahara to planetary bloom ecologies. While phosphorous rarely contends with fossil fuels in the environmental imaginary, I argue that its role in supporting capital and

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Fight for your alienation: The fantasy of employability and the ironic struggle for self-exploitation [PDF]

, 2013
This paper draws on Lacanian psychoanalysis, to introduce employability as a cultural fantasy that organizes identity around the desire to shape, exploit and ultimately profit from an employable self. Specifically, the paper shows how individuals seek to
