Governance and infrastructure as pillars of performance: A socio‐ecological analysis of Ethiopian botanical gardens

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
While botanical gardens are often perceived merely as recreational spaces for a weekend walk, in the Global South, they are true lifelines for nature and for the people who depend on it. Our research in Ethiopia explored what actually keeps these gardens running long‐term.

Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Polypyrrole Nanofibrous Aerogel for Pressure Sensing and Anionic Contaminant Remediation

open access: yesSmall, EarlyView.
Nanofibrous aerogels (NFAs), highly porous ultralow‐density networks of entangled nanofibers, are conformally coated with polypyrrole (PPy) to provide a multifaceted material platform. Leveraging NFA's high surface area and mechanically robust structure with the conductive properties of PPy enables pressure‐responsive sensing for flexible electronics ...

Ultrafast Mechanochemical Synthesis of Plasmonic Transition Metal Nitride Nanoparticles

open access: yesSmall, EarlyView.
Mechanochemistry enables ultrafast synthesis of plasmonic transition metal nitride nanoparticles in minutes rather than hours without external heat supply. The resulting mono‐ and mixed‐metal nitrides display tunable plasmonic absorption, demonstrating a potentially scalable route to refractory plasmonic materials.

Morphological Stabilization of CsPbBr3 Quantum Dot Films Enabled by PVC‐g‐PMMA Graft Copolymer Encapsulation for Water‐Robust Color Conversion

open access: yesSmall, EarlyView.
Poly(vinyl chloride)‐graft‐poly(methyl methacrylate) encapsulation enabled formation of water‐stable CsPbBr3‐quantum‐dot fims with enhanced photoluminescence (PL) retention upon exposure to water, UV radiation, and ethanol. Time‐dependent ex situ transmission electron microscopy with quantitative particle segmentation identified the coefficient of ...
