Advanced Science, EarlyView.The dynamic “spring‐like” behavior of Pd─Cu dual atoms with PdN3─CuN3 coordination structure can be stretched and recovered with potential variation, which remarkably elevates the structural stability and catalytic activity of Cu atoms for electrocatalytic reduction reactions in strong‐acid electrolytes. The modulated electron‐orbit coupling effect and

TERA: A Simulation Environment for Terrain Excavation Robot Autonomy [PDF]
arXivDeveloping excavation autonomy is challenging given the environments where excavators operate, the complexity of physical interaction and the degrees of freedom of operation of the excavator itself. Simulation is a useful tool to build parts of the autonomy without the complexity of experimentation.

Organocatalytic C─O Bond Cleavage and Asymmetric Transformations via [1,3]‐Sigmatropic Rearrangement
Advanced Science, EarlyView.A direct asymmetric strategy for fulfilling the functional group transfer by aryl ether cleavage and migration is developed, representing the first Brønsted base‐catalyzed asymmetric [1,3]‐sigmatropic rearrangement reaction. The resulting chiral benzofuran products generated through this strategy exhibit significant 3D‐dimensionality and demonstrate ...

3D Operation of Autonomous Excavator based on Reinforcement Learning through Independent Reward for Individual Joints [PDF]
arXivIn this paper, we propose a control algorithm based on reinforcement learning, employing independent rewards for each joint to control excavators in a 3D space. The aim of this research is to address the challenges associated with achieving precise control of excavators, which are extensively utilized in construction sites but prove challenging to ...

Artificial Gold Enzymes Using a Genetically Encoded Thiophenol‐Based Noble‐Metal‐Binding Ligand
Angewandte Chemie, Volume 137, Issue 12, March 17, 2025.A new class of artificial metalloenzymes containing genetically encoded noble‐metal‐binding sites featuring a non‐canonical thiophenol‐based amino acid, which serves as an excellent soft ligand for binding various noble metals, was developed. The corresponding gold(I) enzyme was characterised, confirming gold binding to the thiophenol, and successfully
