Space Pump: Repairable 3D‐Printed Bioinspired Pneumatic Peristaltic Pump for Fluid and Regolith Transport in Space

Advanced Intelligent Systems, EarlyView.
The space pump transports lunar regolith under vacuum condition. A fully 3D‐printed biomimetic peristaltic pump demonstrates reliable transport of liquids and solids using pneumatic ring actuators and flexible fused filament fabrication. The system operates under atmospheric and vacuum conditions, achieves high flow rates, and enables self‐priming ...

Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

American Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Negotiating contested spaces and places: Narratives of social suffering and resistance in racialized Cape Town communities

American Journal of Community Psychology, EarlyView.
Abstract This study employs a schizocartographic approach to explore community narratives of space, memory, and violence in Kraaifontein, Cape Town. Through participants' accounts, ordinary places—gardens, shops, blocks, sports grounds, and streets—emerge as ambivalent geographies where trauma, resilience, and belonging intersect.

Design and Performance of a High‐Efficiency Inhibitor: Synergistic Effect of Modified Chitosan and Boron Nitride Nanosheets on Steel Protection

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Metal corrosion causes significant economic losses and safety hazards, underscoring the urgent need for effective, environmentally friendly corrosion inhibitors. In this study, an organic–inorganic composite inhibitor, chitosan–glucose–BN (CS–GL–BN) was developed to protect Q235 mild steel in a 3.5‐wt% NaCl solution.

Scale‐space image analysis for mapping spotted knapweed in grassland ecosystems

Applications in Plant Sciences, EarlyView.
Abstract Premise This study investigates the value of scale‐space representations of spatial features for the identification and mapping of invasive plants using high‐resolution multispectral imagery. Scale‐space representations combine the two‐dimensional spatial domain with a third dimension representing spatial scale, such that features can be ...

Pure Inverse Spin Hall Effect in Ferromagnetic Ni80Fe20/Y3Fe5O12 (YIG) Heterostructures via the Longitudinal Spin Seebeck Effect

Advanced Physics Research, EarlyView.
A pure inverse spin Hall effect (ISHE) is demonstrated in ferromagnetic Ni₈₀Fe2₀/YIG heterostructures via the longitudinal spin Seebeck effect. By employing symmetry‐controlled geometries and reference samples, anomalous Nernst contributions are quantitatively eliminated, revealing intrinsic spin–charge conversion in Ni₈₀Fe2₀.
