Photochemical Fuel Carrier Molecules for Robotic Embodied Energy

Advanced Materials, EarlyView.
We designed a novel fuel carrier photoresponsive molecule for on‐demand energy storage and release. Carrier molecules undergo bond scission under UV light to release chemical fuel and locally generate propulsive Marangoni flows. We demonstrate this photochemical embodied energy strategy in small‐scale robots and active matter systems, enabling ...

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

Advanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Self‐Oscillating Helix Showing Amplified Winding and Unwinding Motions

Advanced Materials, EarlyView.
The hydrogel helix exhibits autonomous oscillation synchronized with the Ru(bpy)32+/3+ redox cycle in the Belousov–Zhabotinsky reaction. Periodic winding–unwinding accompanies magnified motion along one direction within the gel phase. ABSTRACT Helical architectures in nature amplify motion via winding–unwinding.

Current Switching of Topological Spin Chirality in the van der Waals Antiferromagnet Co1/3TaS2

Advanced Materials, EarlyView.
Spin chirality plays a central role in quantum magnetism, governing spin winding and generating real‐space Berry phases. We propose the intriguing concept of current‐switching spin chirality and demonstrate it via unconventional intrinsic self‐spin‐orbit‐torque in pristine Co1/3TaS2, purely by electrical current and with high energy efficiency.

Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings

Advanced Materials, EarlyView.
This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external
