3D‐Printed Sulfur‐Derived Polymers With Controlled Architectures for Lithium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
Rheology‐guided formulation design for direct ink writing enables the fabrication of 3D sulfur copolymer cathodes with controlled architectures for lithium‐sulfur batteries. The printed electrodes exhibit multiscale porosity and high sulfur utilization, delivering enhanced electrochemical performance compared to conventional cast electrodes.

A Recipe for Eccentricity and Inclination Damping for Partial-gap Opening Planets in 3D Disks

The Astrophysical Journal
In a previous paper, we showed that, like the migration speed, the eccentricity damping efficiency is modulated linearly by the depth of the partial gap a planet carves in the disk surface density profile, resulting in less efficient e -damping compared ...

Excitation and Propagation of Eccentricity Disturbances in Planetary Systems

, 2004
The high eccentricities of the known extrasolar planets remain largely unexplained. We explore the possibility that eccentricities are excited in the outer parts of an extended planetary disk by encounters with stars passing at a few hundreds of AU ...

Streaming Torque in Dust–Gas Coupled Protoplanetary Disks

The Astrophysical Journal
We investigate the migration of low-mass protoplanets embedded in dust–gas coupled protoplanetary disks. Linear calculations are performed with respect to the Nakagawa–Sekiya–Hayashi (NSH) equilibrium within a shearing sheet. We find that the dusty quasi-

Implications for the formation of Oort cloud-like structures and interstellar comets in dense environments

Astronomy & Astrophysics
Most stars form in dense stellar environments, where frequent close encounters can strongly perturb and reshape the early architecture of planetary systems.

Long-term Evolution of Warps in Debris Disks—Application to the Gyr-old System HD 202628

The Astrophysical Journal, 2023
We present the results of N -body simulations meant to reproduce the long-term effects of mutually inclined exoplanets on debris disks, using the HD 202628 system as a proxy.

Orbital migration and the frequency of giant planet formation [PDF]

, 2002
We present a statistical study of the post-formation migration of giant planets in a range of initial disk conditions. For given initial conditions we model the evolution of giant planet orbits under the influence of disk, stellar, and mass loss torques.

3D Printing of Highly Dense and Translucent Zirconia Parts for Dental Applications: Effect of Filament Overlapping

Advanced Materials Technologies, EarlyView.
This study formulated a 5Y‐PSZ zirconia paste for extrusion‐based additive manufacturing via direct ink writing, producing dense ceramic structures for dental applications. A colloidal approach with 47 vol% nanometric powder and tailored additives optimized rheology and printability.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
