Effects of Engineered Dam Releases on Benthic Assemblages During Drought and Comparison With Unregulated Reaches

River Research and Applications, EarlyView.
ABSTRACT River regulation following damming is often associated with deleterious downstream effects, in large part due to reduced total discharge and disruption of seasonal flooding. These effects would be expected to be exacerbated by drought, particularly extended drought.

From Innovation to Sustainability: Integrating Fintech, Green Trade and Knowledge Systems for Circular Growth in Sub‐Saharan Africa

Sustainable Development, EarlyView.
ABSTRACT The transition toward circular and sustainable growth remains a major challenge in Sub‐Saharan Africa (SSA), where resource constraints, limited recycling capacity, and infrastructure deficits constrain environmental performance. Drawing on circular economy and innovation systems perspectives, this study examines how financial technology ...

Radiation‐Based 3D Dual‐Mode Thermal Management Devices: Advances in Active/Passive Switching for Energy‐Saving Applications

Small, EarlyView.
Heating and cooling energy demand account for nearly half of the global energy consumption. SH and RC offer sustainable, zero‐energy strategies, but single‐mode devices lack adaptability. 3D dual‐mode devices, exploiting axial, flipping, and bending deformations, provide reversible switching with dynamic or passive control, representing a promising ...

Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices

Small, EarlyView.
True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key
