DuckyDog: An Erect Amphibious Robot with Variable‐Stiffness Legs and Passive Fins

Advanced Intelligent Systems, Volume 7, Issue 7, July 2025.
DuckyDog, a quadruped amphibious robot using erect posture, is proposed with dog‐inspired tendon‐driven compliant legs for walking and paddling, a duck‐inspired body for buoyancy, and passive fins to increase propulsion. It achieves maximum speeds of 0.4 body lengths per second on land and 0.3 on water, demonstrating the ability to navigate in complex ...

Hinge‐Like Mechanochromic Mechanophores Based on [2.2]Paracyclophane

Angewandte Chemie, EarlyView.
Hinge‐like supramolecular mechanophores utilizing [2.2]paracyclophane have been developed. In the force‐free state, the rigid [2.2]paracyclophane forces two luminophores into proximity, leading to excimer‐dominant photoluminescence. Stretching the polyurethane films into which the mechanophores are covalently incorporated results in the structures of ...

Macromolecule‐Driven Supramolecular Polymerization Induced by Crowding Effects

Angewandte Chemie, EarlyView.
A systematic study is presented that investigates the influence of the excluded volume effect by macromolecules on supramolecular polymerizations in organic media. Upon crowding, the discotic supramolecular monomers sequentially assemble into polymers and higher‐order aggregates (HOAs), affected by the macromolecule's concentration, size and polarity ...

Statistical Link Between Bell Nonlocality and Uncertainty Relations in Quantum Mechanics

Annalen der Physik, EarlyView.
Bell nonlocality and uncertainty principle are two distinguished features in quantum mechanics from classical physics. In this work, it is showed the interplay between these two quantum properties. The upper bound of nonlocal correlation strength is determined by accumulation of all local measurement uncertainty, which means that more Bell nonlocality ...

Highly Enantioselective Organocatalysis with Bidentate Halogen Bond Donors

Angewandte Chemie International Edition, Volume 64, Issue 30, July 21, 2025.
In a model Mukaiyama aldol reaction with unbiased substrates, high enantioselectivity was achieved with a modifiable bidentate iodine(I)‐based halogen bonding organocatalyst. The crucial role of halogen bonding was confirmed by the low performance of the corresponding hydrogen bond donor and via DFT calculations.

Embracing Complexity: Peptides as Tuneable Scaffolds in the Construction of Discrete Supramolecular Systems

Angewandte Chemie International Edition, Accepted Article.
Supramolecular chemistry has advanced rapidly, with scientists using fundamental understanding to generate function from simple building blocks. However, synthetic systems are still in their infancy when compared to biology. The increasing use of peptides in supramolecular structures provides a clear roadmap to more complex function; introducing chiral,

Path Integral Spin Dynamics for Quantum Paramagnets

Advanced Physics Research, EarlyView.
The study has developed a path integral method, which is a classical approach, combined with atomistic spin dynamics simulations to calculate thermal quantum expectation values. This method can handle Hamiltonians with non‐linear terms, which are important for describing uniaxial anisotropies and mechanical constraints.
