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

Journal 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.

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Impacts of Fluorination at the Ortho‐Position of Carboxy Groups on Tetrakis(biphenyl)ethene‐Based Hydrogen‐Bonded Framework

Small, EarlyView.
This work provides new findings on the effect of fluorination on the substitution of TPE derivatives and the modulation of the structure and fluorescence properties of hydrogen‐bonded organic framework (HOF) of F‐CBPE. ABSTRACT Fluorination of building block molecules is one of the effective engineering approaches to modulate molecular assembly in ...

Topological Structuring of Adhesive Layers to Enhance Resistance against Interfacial Fracture

Small, EarlyView.
A hybrid bonding method that combines chemical affinity with mechanical interlocking is demonstrated. This approach uses a solution‐based technique to create a porous layer that strongly adheres to one substrate and templates a robust mechanical interlock with the other adherend. By tuning the pore geometry, crack propagation is effectively suppressed,

Facile one‐step synthesis of efficient hybridized local and charge transfer emitter for ultraviolet electroluminescence with low roll‐off

Smart Molecules, EarlyView.
An effective hybridized local and charge‐transfer emitter D3CZ4F featuring multiple C–H⋯F locking interactions was developed, achieving an outstanding EQE of 8.97%, a small roll‐off, an emission peak at 388 nm, and color coordinates of (0.165, 0.025), respectively.

A multifunctional near‐infrared dual‐channel off‐on‐off probe for sequential detection of fluoride and hypochlorous acid: Multimatrix applications

Smart Molecules, EarlyView.
This multifunctional, sequence‐specific probe (DHM) enables stepwise detection: fluoride triggers red/near‐infrared emission via cleavage, then hypochlorous acid induces blue fluorescence. It achieves fast, selective visual detection in environmental samples, foods, and in vivo models.
