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.

Sentipensar [Feel‐Thinking] Cultivates Collective Scientific Sensemaking and Worldbuilding Within and Beyond Ecological Despair

open access: yesScience Education, EarlyView.
ABSTRACT Educating youth about environmental and climate justice is crucial in realizing a sustainable and flourishing future. Yet this can be challenging given the intense eco‐emotions youth experience and express while learning about these consequential realities and their implications.

Mechanically Robust Dicing‐Free Thermoelectric Module Fabrication Using Anion‐Cation co‐Doped Bismuth Tellurides

open access: yesSmall, EarlyView.
NaCl co‐doping effectively enhances the thermoelectric performance of p‐type Bi–Sb–Te (BST) alloys through simultaneous Na+ substitution at Sb sites and Cl− substitution at Te sites, inducing local lattice distortion and defect engineering. At low doping levels, carrier transport is optimized by tuning carrier concentration and suppressing antisite ...

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

Adhesive Protein Nanoparticles Control Emulsion Properties via Tunable Interdroplet Linking

open access: yesSmall, EarlyView.
In this study, pea protein nanoparticles were probed for their ability to link emulsion droplets. Experiments across multiple length scales showed that the nanoparticles form shear‐resistant links via bridging interactions from the thin film between droplets.
