Free-floating Planets Produced by Planet-Planet Scatterings: Ejection Velocity and Survival Rate of Their Moons

The discovery of numerous free-floating planets (FFPs) has intensified interest in their origins and dynamical histories. A leading formation mechanism is planet-planet scatterings in unstable multi-planetary systems, which can naturally lead to planetary ejections.

Multimodal Imaging of Strain and Light Emission of Core–Shell InGaN/GaN Wires under a Sub‐Micrometer Polychromatic X‐Ray Probe

Advanced Materials Interfaces, EarlyView.
Micro‐Laue diffraction and excited optical X‐ray luminescence are used to study InGaN/GaN core‐shell wires on the BM32 beamline at the European Synchrotron. Multimodal imaging of X‐ray fluorescence, deviatoric strain tensors and optical emissions is performed using simultaneous mapping.

Advanced Ceramics in Aerospace and Defense: The Interrelationship between Traditional and Additive Manufacturing Approaches

Advanced Materials Technologies, EarlyView.
Additive manufacturing revolutionizes production by enabling on‐demand, customized, and sustainable manufacturing with streamlined supply chains. While metal and polymer AM are well‐established, advanced ceramic AM is rapidly emerging, overcoming traditional material challenges.

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

Advanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Laser Micromachining of Liquid Metal Patterns for Stretchable Electronic Circuits

Advanced Materials Technologies, EarlyView.
A cleanroom‐free fabrication strategy combines UV‐laser micromachining with a copper foil wetting layer to rapidly produce high resolution, liquid metal based stretchable electronic circuits on diverse substrates. The scalable, maskless process enables complex circuit designs (<$<$3 h, ∼$\sim$15/device) with excellent electrical stability under strain,
