Arc length monitoring and closed-loop quality control for GTA-WAAM

open access: yesVirtual and Physical Prototyping
This study aims to enhance the monitoring and control of arc length in Wire Arc Additive Manufacturing with Gas Tungsten Arc (GTA-WAAM). Accurate measurement and closed-loop control of arc length in WAAM is challenging, especially under conditions of low

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses

open access: yesAdvanced Science, EarlyView.
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Microstructure transformation and mechanical behavior in NiTi alloys fabricated by dissimilar double wires arc additive manufacturing

open access: yesJournal of Materials Research and Technology
In traditional wire arc additive manufacturing process, it is difficult to control the chemical composition of deposition layer. A double filler wire with alternating current was proposed to fabricate the NiTi alloy.

Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics

open access: yesAdvanced Science, EarlyView.
We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...

Multimodal Wearable Biosensing Meets Multidomain AI: A Pathway to Decentralized Healthcare

open access: yesAdvanced Science, EarlyView.
Multimodal biosensing meets multidomain AI. Wearable biosensors capture complementary biochemical and physiological signals, while cross‐device, population‐aware learning aligns noisy, heterogeneous streams. This Review distills key sensing modalities, fusion and calibration strategies, and privacy‐preserving deployment pathways that transform ...
