Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp

open access: yesSmall, EarlyView.
Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.

Obligation, Exemption and Remission: The Multi‐Layered Functioning of the Poll Tax (Cizye) in Ottoman Governance during the Long Eighteenth Century

open access: yesHistory, EarlyView.
Abstract This article examines the poll tax (Ottoman Turkish cizye; Arabic jizya) levied on non‐Muslim subjects of the Ottoman Empire, not as a fixed, one‐dimensional tax item within the Ottoman fiscal system but as a multi‐layered administrative instrument organized around obligation, exemption and remission.

The Momentum of ‘Developed’: Bodies of Water, Aging Bodies and Malta's Interventions at the UN

open access: yesHistory, EarlyView.
Abstract Histories of major powers continue to shape how many scholars conceptualize internationalism. By focusing on Malta's interventions at the UN challenges, this article challenges such narrative. In particular, it examines Arvid Pardo's 1967 petition that the seabed be reconceived and protected as the ‘common heritage of mankind’ and Vincent ...

Distinct element method for static and flow mobility characteristics of lunar regolith based on particle shape characteristics

open access: yesYantu gongcheng xuebao
Since it exhibits uniquely grain shape, physical and mechanical characteristics, the lunar regolith is extremely important for utilization of in-situ resources, selection of base station location and construction in lunar exploration.

STRATIFIED ADAPTATION: Infrastructure, Elevation, and Cascading Floods in the Urban Mekong Delta

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Flood‐prone cities in the global South are increasingly the target of infrastructure projects aimed at building climate ‘resilience’. At the same time, residents of these cities take adaptation to flooding into their own hands. In this article we examine the interrelationship between household‐scale and urban‐scale flood mitigation projects in
