From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.

Macroscopic Convective Fluid Flows Arising From Binding of Ions and Small Molecules to Proteins

Small, EarlyView.
The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from urease by EDTA pre‐treatment results in binding‐induced convective fluid flow.

Autonomous and Communicative Microcapsule Systems for Life‐Like Homeostatic pH Regulation

Small, EarlyView.
A dual‐microcapsule system mimicking biological homeostasis is developed, enabling programmable pH oscillations through antagonistic enzymatic feedback. Monodisperse urease and esterase capsules, produced via hybrid‐junction 3D‐printed microfluidics with epoxy‐modified channels, exhibit adaptive shell permeability and inter‐capsule communication.

Perfluorohexanone for Clean Fire Suppression: Mechanisms, System Design, Applications, and Future Directions

Safety Science and Technology, EarlyView.
Driven by halon and high GWP agent phase out, perfluorohexanone is increasingly deployed in enclosures such as data centers, marine machinery spaces, and industrial process lines. This review summarizes application performance, discharge and distribution design, material compatibility, and byproduct control and maps practical gaps for large volume and ...
