Active Sites‐Enriched Hierarchical Weyl Semimetal WTe2 Nanowire Arrays for Highly Efficient Hydrogen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
Weyl semimetal WTe2 possesses high conductivity and robust topological surface states. A controlled synthesis method for carbon fiber‐supported WTe2 and core–shell WO3−x–WTe2 nanowire arrays is proposed. The WTe2 nanowires are highly crystalline, uniform, and vertically aligned, providing abundant active sites and durability in hydrogen evolution ...

Surface Engineering‐Induced d‐Band Center Down‐Regulation in High‐Entropy Alloy Nanowires for Enhanced Nanozyme Catalysis

open access: yesAdvanced Science, EarlyView.
PtRuFeCoNi HEA NWs are synthesized by adjusting the metal composition and surface‐engineered with PDA to create HEA NWs@PDA nanozymes with superior catalytic activities and photothermal properties. DFT calculations confirm that self‐polymerized PDA surface engineering moderately lowers the d‐band center of the HEAs, optimizes the surface charge ...

Demonstrating CavePI: Autonomous Exploration of Underwater Caves by Semantic Guidance [PDF]

open access: yesarXiv
Enabling autonomous robots to safely and efficiently navigate, explore, and map underwater caves is of significant importance to water resource management, hydrogeology, archaeology, and marine robotics. In this work, we demonstrate the system design and algorithmic integration of a visual servoing framework for semantically guided autonomous ...
