Advanced Functional Materials for Marine Energy Utilization

open access: yesInterdisciplinary Materials, EarlyView.
Marine renewable energy is an important future clean energy supply. We construct and sort out the material system for marine energy capture and conversion, transmission, storage, and utilization for the first time. ABSTRACT Several features of marine energy, including large reserves, sustainable utilization, environmental friendliness, make it a ...

Distinguishing Intrinsic Descriptors of Grain Boundary Segregation Between Metallic and Non‐Metallic Solutes in BCC Fe via Machine Learning

open access: yesMaterials Genome Engineering Advances, EarlyView.
A combined DFT–interpretable machine learning framework identifies the intrinsic descriptors governing grain boundary segregation in BCC Fe. Geometric effects dominate metallic solutes, whereas electronic bonding controls nonmetallic solutes, exhibiting an overall contrasting trend Voronoi volume–segregation energy relationships.

Biomimetic Multifinger Tactile Sensing and Contact‐Regulated Palpation for Autonomous Breast Tumor Localization

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Early detection of breast abnormalities remains challenging: manual palpation is subjective and operator‐dependent, while imaging modalities may miss small or subtle stiffness anomalies. This paper presents a biomimetic multifinger robotic palpation approach intended to support early breast‐cancer screening and follow‐up assessment as a proof ...
