Vision‐Based Handover and Organization of Robotic Scrub Nurse for Seamless Surgical Flow

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a pose estimation‐based robotic scrub nurse (PERSN) that assists surgical procedures by estimating the surgeon's hand position, orientation, and grasping state, along with the constraint‐based 6D pose of surgical instruments. User evaluations show that PERSN provides greater immediate usability and reduces physical demand compared ...

Concerted Proton and Electron Transfer in Heterogeneous Electrocatalytic CO2 Reduction

open access: yesAngewandte Chemie, EarlyView.
Concerted proton‐electron transfer (CPET) enables CO2‐to‐CO conversion with significantly reduced energy cost compared to cation‐stabilized pathways. Under controlled mass transport of proton donors, CPET dominates at modest potentials. At higher overpotentials, a cation‐stabilized pathway is found to dominate.

Liquid Jetting‐Based Miniature Robotic Navigation in Confined Fluidic Spaces

open access: yesAdvanced Intelligent Systems, EarlyView.
We introduce a new class of liquid‐jetting‐based miniature robots (JetBots) ranging in size from mm‐to‐cm, featuring a unified approach in design, fabrication, and actuation. They demonstrate fast locomotion (30.3 cm/s), rapid steering (648.8°/s), and diverse functions, such as puncturing soft materials and unlimited cargo sampling and delivery, paving

Accelerated Discovery‐to‐Unveiling of High‐Performance and Affordable Ammonia Electrode Process by Human–Machine Collaboration Framework

open access: yesAngewandte Chemie, EarlyView.
By employing dimensionally reduced reaction descriptors, a human–machine collaboration framework for efficient electrochemical nitrate reduction to NH3 electrocatalysts screening is established and drastically shorten the discovery timeframe. A new kinetic model is established in combination with a rotating ring‐disk electrode, unveiling the pivotal ...

Systematic Review and Meta‐Analysis of Endovascular Therapy Effectiveness for Unruptured Saccular Intracranial Aneurysms

open access: yesStroke: Vascular and Interventional Neurology
Background Currently, endovascular treatment of intracranial aneurysms is limited by low complete occlusion rates. The advent of novel endovascular technology has expanded the applicability of endovascular therapies; however, the superiority of novel ...
