Irregular Moons Possibly Injected from the Outer Solar System by a Stellar Flyby

open access: yesThe Astrophysical Journal Letters
The irregular moons orbit the giant planets on distant, inclined, and eccentric trajectories, in sharp contrast with the coplanar and quasicircular orbits of the regular moons.

Binder Engineering Suppresses Jahn–Teller‐Driven Mn Dissolution and Enables High‐Loading MnO2 Cathodes for Aqueous Zn‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A Zn2+‐coordinated poly(vinylidene fluoride) binder is shown to suppress Jahn–Teller‐driven Mn dissolution while improving dispersion, wettability, and structural integrity in thick MnO2 cathodes. This simple binder‐engineering strategy enables high‐loading aqueous Zn‐ion batteries with enhanced areal capacity, cycling stability, and practical promise ...

Ionic Transportation Induced Electric Field Modulation in Porous Ecoflex/PTFE with Confined Liquid for High‐Performance Contact Electrification Power Generation

open access: yesAdvanced Functional Materials, EarlyView.
Porous Ecoflex/PTFE composite with encapsulated liquid generates electricity through ionic migration induced by dynamic pore deformation, creating non‐uniform electric fields that drive charge induction on electrodes. This mechanism enhances charge transfer and ensures stable contact electrification performance, achieving 12 V and 4 nC with consistent ...

Metastatic oral malignant melanoma transformed from pre-existing pigmented lesions in mandibular gingiva: Report of an unusual case

open access: yesJournal of Dental Sciences, 2013
The objective of this study is to report the transformation of a 10-year history of melanotic mandibular gingival lesion into primary oral melanoma (POM) in a 37-year-old Taiwanese woman. The patient declined all treatments and died of widespread disease

Design and ballistic analysis of the mission for long-term study of the asteroid Apophis by a nanosatellite with an electric rocket propulsion system

open access: yesКосмические аппараты и технологии, 2020
The paper considers non-spherical objects with low gravitational attraction, such as asteroids, satellites of the planet and comets. We considered possibility of a mission to small bodies of the solar system of irregular shape on the example of the ...

Collisional Origin of Families of Irregular Satellites

open access: yesThe Astronomical Journal, 2004
A distinctive feature of the irregular moons of the giant planets is their orbital grouping. Previously, the prograde and retrograde groups of irregular moons at Jupiter were believed to be groups of fragments produced by the disruption of two large moons.

Inventory of the inner and irregular satellites in the Jovian system [PDF]

open access: yes, 2022
openThis study presents a comprehensive inventory of the inner and irregular satellites in the Jovian system. The satellites are categorised according to the orbital parameters such as samimajor axis, orbital inclination and eccentricity, and physical ...

In Situ Crystalline‐Amorphous Composite Oxide Structure Suppressing Thermal Wear Instability for Refractory Multi‐Principal Element Alloy

open access: yesAdvanced Functional Materials, EarlyView.
An effective strategy is developed to overcome the medium temperatures wear resistance degradation in refractory multi‐principal element alloys. By utilizing chemical short‐range ordering to trigger oxygen‐induced amorphization, a composite oxide structure is formed, which combines high hardness with robust stiffness.

An Ultradeep Survey for Irregular Satellites of Uranus: Limits to Completeness [PDF]

open access: yesThe Astronomical Journal, 2005
We present a deep optical survey of Uranus' Hill sphere for small satellites. The Subaru 8-m telescope was used to survey about 3.5 square degrees with a 50% detection efficiency at limiting red magnitude m = 26.1 mag. This magnitude corresponds to objects that are about 7 km in radius (assuming an albedo of 0.04).
