A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Effect of Magnetic Anisotropy and Gradient‐Induced Dzyaloshinskii‐Moriya Interaction on the Formation of Magnetic Skyrmions

open access: yesSmall, EarlyView.
Magnetic force microscopy of gradient‐induced CoPt films reveals that magnetic skyrmion size and density vary with film thickness, gradient polarity, and applied magnetic field. An increased skyrmion density is observed in films exhibiting higher magnetic anisotropy.

On‐Tip Polymerization Method for Multimodal Characterization of Nanoparticles with Electron/Ion Imaging and Atom Probe Tomography

open access: yesSmall Methods, EarlyView.
This study presents an on‐tip polymerization method that employs a needle substrate with a designed through‐microchannel (“needle‐eye”) to retain a picoliter‐scale solution of nanoparticles. Using a resin precursor as the solution, polymerization is carried out in situ at the needle tip.
