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 ...

Self‐Assembled Silicon@Silica Metasurfaces with High‐Quality Resonances in the Infrared

open access: yesSmall Science, EarlyView.
An artificial magnetic resonance is created via the fabrication of a 2D silicon particle assembly. This particle to metasurface bottom‐up synthetic strategy presents many structural defaults and deviates largely from the ideal metasurfaces produced through top‐down techniques. Even so, the effective medium of this material appears to display a magnetic

Balanced Adsorption Ability of NiFeP by Nonmetal Doping for Enhanced Water Dissociation Kinetics and Stability

open access: yesSmall Methods, EarlyView.
F incorporation in NiFeP (NiFePF) tailors the electronic structure of Ni, Fe, and P, optimizing *OH/*H adsorption on active sites. The balanced *OH/*H adsorption ability in NiFePF accelerates water dissociation and facilitates the desorption of *OH and alleviates poisoning active center and surface hydroxylation, limiting the surface reconstruction of ...

Metamodeling of Void Closure during Hot Flat Rolling

open access: yessteel research international, EarlyView.
This work aims to present a fast metamodel for void closure during hot flat rolling. The model takes into account every individual void of void distributions as found in industrial material and is capable of calculating the resulting void closure within only few seconds of computational time without loosing significant accuracy compared to expensive ...
