Photothermal‐Expedited Ion Transport Kinetics for Efficient Electrocatalytic Hydrogen Evolution

open access: yesNational Materials, EarlyView.
The photothermal effect of two‐dimensional graphdiyne is explored via combined experiments and simulations and is further fully leveraged to synergistically expedite reactive ion transport kinetics and enhance intrinsic site activity toward a boosted electrocatalytic hydrogen evolution reaction (HER). The HER performance is thus elevated to rank at the

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 ...
