Advanced Robotics Research, EarlyView.Fuel‐free Cu2O‐based micromotors functionalized with β‐cyclodextrin actively remove bisphenol A from water under visible light. The cyclodextrin shell captures BPA and enhances micromotor motility, leading to faster degradation and higher overall removal than nonfunctionalized Cu2O and Cu2O@Au.

SAR Target Recognition via Meta-Learning and Amortized Variational Inference
Sensors, 2020 The challenge of small data has emerged in synthetic aperture radar automatic target recognition (SAR-ATR) problems. Most SAR-ATR methods are data-driven and require a lot of training data that are expensive to collect.

Advanced Science, EarlyView.Here, we establish a quantitative relationship between the electrostriction coefficient (Q33) of FRPs and their interplanar spacing (d): Q33 = 100(Δd/d0+1) × Q33(s). Using this model, we fabricated high‐performance soft robots, including a biomimetic crawler (with a speed of 27 cm/s) and a butterfly (with a thrust‐to‐weight ratio of 0.71).

FOS3D: A Fluorescence‐Enabled Toolkit for Characterizing a Three‐dimensional Osteosarcoma Model
Advanced Science, EarlyView.FOS3D describes fluorescent (F) osteosarcoma (OS) cells in a tri‐dimensional (3D) model. The study comprises three phases: development, where biofabrication parameters are tuned to achieve cytocompatibility and tumor‐specific mechanical properties in cell‐laden gelatin methacryloyl constructs; validation, where whole‐well fluorescence reading is ...

Advanced Science, EarlyView.Supramolecular hydrogels enable real‐time visualization of mechanical stress through supramolecular switching mechanotransduction. Adamantane‐modified cellulose functions as a responsive domain that undergoes an on–off transition between hydrated and dehydrated states via reversible β‐cyclodextrin–adamantane complexation and decomplexation.

Coupled Electronic and Ionic Conductivity in Strain‐Stiffening Hydrogels
Advanced Science, EarlyView.A soft PVA–PABA hydrogel is developed that couples tissue‐like strain‐stiffening mechanics with dual ionic–electronic conduction. Dynamic boronic crosslinks enable self‐assembled percolative pathways, producing deformation‐responsive resistance with a stabilization plateau at stiffening onset, revealing alignment‐assisted charge transport and advancing
