Sustainable Structural Hot‐Melt Adhesives Enabled by Functionalized Crystalline Lamellae

Advanced Materials, EarlyView.
A high‐performance, recyclable hot‐melt adhesive is developed from renewable materials. It features functional crystalline lamellae that enhance shear strength and enable closed‐loop recycling. The adhesive also provides excellent water and oxygen barrier properties, meeting both sustainability and performance demands for advanced bonding and sealing ...

Electrically Tunable Friction: From Sticky to Slippery with Ionic Hydrogels

Advanced Materials, EarlyView.
This work demonstrates electrically tunable friction “from sticky to slippery” using ionic hydrogels, achieving reversible more‐than‐fifty‐fold modulation without liquid lubricants. An electric field extracts a salt‐rich interfacial layer that dramatically reduces friction.

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.

Holographic Whole‐Object Photopolymerization Preserving Director Alignment in Liquid Crystalline Actuators

Advanced Materials, EarlyView.
Holographic microlithography enables the fabrication of fully connected 3D liquid crystalline structures in a single exposure. The process maintains precise control over the director orientation within the entire object, preventing local director distortions typically observed in sequential printing.

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

Advanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...
