Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

Enhanced Acceleration and Escape of Hydrogen Pickup Ions Upstream from Mars by Interplanetary Shocks

open access: yesThe Astrophysical Journal
The pickup process of newly ionized hydrogen (H) from the Martian extended exosphere represents an important H ^+ escape channel on Mars. It is generally believed that interplanetary (IP) shocks can accelerate the pickup ions and, in turn, affect the ...

Mirror instability driven by pickup ions in the outer heliosheath

open access: yesThe Astrophysical Journal, 2020
<p><span class="fontstyle0">Kinetic linear instability analysis and hybrid simulations are carried out to examine the role of mirror instability in scattering the pickup ions in the outer heliosheath. The dynamics of these pickup ions is essential to<br />the understanding of the energetic ...

Autonomous Machine Learning‐Based Classification and Arrangement of Submillimeter Objects Using a Capillary Force Gripper

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study presents an automated system integrating a capillary force gripper and machine learning‐based object detection for sorting and placing submillimeter objects. The system achieved stable and simultaneous manipulation of four object types, with an average task time of 86.0 seconds and a positioning error of 157 ± 84 µm, highlighting its ...

Interstellar and Inner Source Pickup Ions Observed with Swics on Ulysses [PDF]

open access: yes, 1998
Many species of pickup ions, both of interstellar origin and from an inner, distributed source have been discovered using data from the Solar Wind Ion Composition Spectrometer (SWICS) on Ulysses.

Proton Cyclotron Waves and Pickup Ion Ring Distribution Instabilities Upstream of Mars

open access: yesGeophysical Research Letters
Proton cyclotron waves (PCWs) upstream of Mars are thought to be associated with the instabilities of pickup ions. The instabilities of pickup ions of ring distributions have larger maximum growth rates compared with beam distributions.

On the origin of inner‐source pickup ions

open access: yesGeophysical Research Letters, 2003
In situ measurements of pickup ions (PUI) exhibit a component that has nearly thermalized with the solar wind. This implies an origin close to the Sun and is generally ascribed to interaction of the solar wind with interplanetary dust particles (IDPs).

Cassini CAPS Identification of Pickup Ion Compositions at Rhea [PDF]

open access: yesGeophysical Research Letters, 2018
AbstractSaturn's largest icy moon, Rhea, hosts a tenuous surface‐sputtered exosphere composed primarily of molecular oxygen and carbon dioxide. In this Letter, we examine Cassini Plasma Spectrometer velocity space distributions near Rhea and confirm that Cassini detected nongyrotropic fluxes of outflowing during both the R1 and R1.5 encounters ...

Experimental methods in chemical engineering: Magnetometry

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Magnetometry is a non‐invasive technique to characterize the behaviour of magnetic materials of which the most common contain Fe, Co, and Ni. Vibrating sample magnetometers (VSMs) vibrate samples at a fixed frequency in a static, homogeneous magnetic field to induce a voltage in pick up coils according to Faraday's law of induction.

Fluctuations Driven by Multicomponent Pickup Ion Distributions in the Outer Heliosheath

open access: yesThe Astrophysical Journal
The stability of a realistic multicomponent pickup ion (PUI) velocity distribution derived from a global model of neutral atoms in the heliosphere, which treats hydrogen and helium atoms self-consistently and includes equations for electrons and helium ...
