Porous Hybrid Soft Actuators From Liquid Crystal Networks and Lyotropic Chromonic Liquid Crystal Templated Hydrogels

Advanced Materials, EarlyView.
The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Micro-computed tomographical and histopathological analyses of medial tibial plateaus from patients with subchondral insufficiency fracture or osteoarthritis of the knee

Arthritis Research & Therapy
Background Subchondral insufficiency fracture of the knee (SIFK) is a rare and rapidly progressing knee joint disease. The typical diagnostic finding of SIFK by magnetic resonance imaging (MRI) is a subchondral hypointense line around the bone marrow ...

Machine Learning–Assisted Bio‐Interfacial Engineering Resolves Structural–Functional Conflicts in Nanocomposites

Advanced Materials, EarlyView.
A machine learning‐guided bio‐interfacial design strategy resolves the long‐standing strength–toughness–functionality trade‐off in nanocomposites. By efficiently mapping high‐performance regions in the composition–processing space, the approach delivers hierarchically entangled, nanosheet‐pinned architectures that combine mechanical robustness ...

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 ...
