The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

A Comparative Evaluation of Carbonaceous and Alloy Type Anodes for Sodium‐Ion Batteries: Capacity, Scalability, and Sustainability Perspectives

Small, EarlyView.
This review critically compares the electrochemical performance of carbon‐based and alloy‐type anodes for sodium‐ion batteries, with an emphasis on strategies that enhance practical deployment. It highlights how synergistic optimization of microstructure, electrolyte, and presodiation improves hard carbon, while nanostructuring and interfacial ...

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Human Colitis‐on‐Chip Model Reveals Dual Roles of Butyrate in Epithelial and Macrophage Defense Against Candida albicans Tissue Invasion

Small, EarlyView.
This study establishes a human immunocompetent colitis‐on‐chip model that mimics inflamed gut mucosa and enables quantitative analysis of Candida albicans tissue invasion under DSS‐induced injury. It reveals that microbiota‐derived butyrate simultaneously stabilizes epithelial junctions and reprograms macrophages via HDAC/NLRP3‐dependent mechanisms ...

Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators

Small, EarlyView.
We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.
