Sustainable Cities Under Pressure: Climate Risk, Oil Price Uncertainty, and Technological Innovation in GCC Countries

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the dynamic interactions between climate risk, oil price uncertainty (OPU), and technological innovation in shaping Sustainable Development Goals (SDGs) related to Sustainable Cities and Communities (SCC) across Gulf Cooperation Council (GCC) countries from 2005 to 2024. Using a panel Time‐Varying Interactive Fixed Effects (

Photo‐Activated Merging Cascades in Droplet Swarms Upon Synergistic Solvation of Surfactants

open access: yesSmall, EarlyView.
UV activates the motility of UV‐responsive droplets through a decylammonium/carbamate crystalline layer at the air/water interface. Upon merging with immobilized C12E3 surfactant droplets in the layer, hybrid droplets form which dissolve the layer due to synergistic solvation. In large droplet fields, this non‐linear behavior drives cascading events of

Dual‐Functionality, Bio‐Friendly Artificial Muscles for Actuation and Motion Sensing in Smart Wearable Systems

open access: yesSmall, EarlyView.
This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

CMesh: A Polymer‐Free Carbon Nanotube Scaffold for Robust TEM Specimen Preparation of Porous Graphene

open access: yesSmall, EarlyView.
CMesh, a polymer‐free carbon nanotube scaffold, reinforces pristine and pre‐existing porous graphene during TEM specimen preparation while preserving clean suspended imaging windows. The tunable mesh enables high‐yield transfer onto standard grids, atomic‐resolution imaging of nanopores and defects, and in situ observation under demanding microscopy ...
