A New Database of Giant Impacts over a Wide Range of Masses and with Material Strength: A First Analysis of Outcomes

open access: yesThe Planetary Science Journal
In the late stage of terrestrial planet formation, planets are predicted to undergo pairwise collisions known as giant impacts. Here, we present a high-resolution database of giant impacts for differentiated colliding bodies of iron–silicate composition,

Synthesis and Optical Properties of Single‐Crystalline Phosphors Gd3In2Ga3O12:RE3+ (RE = Nd3+ and Ho3+) Grown via the Optical Float Zone Method

open access: yesAdvanced Photonics Research, EarlyView.
Nd3+‐ and Ho3+‐doped Gd3In2Ga3O12 single crystals have been successfully synthesized via the optical float zone method. Their structure and optical characterization demonstrate efficient narrow‐line 4f–4f emission, low cross‐relaxation, and bright photoluminescence, indicating their potential as advanced optical materials for photonic applications. The

Bleeding‐Mimetic Damage‐Detecting and Self‐Healing Modular Skin for Inflatable Structures

open access: yesAdvanced Robotics Research, EarlyView.
A damage‐detecting and self‐healing system inspired by the human bleeding mechanism is developed for inflatable structures, using a liquid conductive elastomeric material enclosed in a small pouch. This material, composed of uncured elastomer, its curing agent, conductive particles, and a dispersant, solidifies only after being exposed to air and ...

Snap and Jump: How Elastic Shells Pop Out

open access: yesAdvanced Robotics Research, EarlyView.
Indent an elastomeric shell and let it go. The spherical shells can store and release the elastic energy. Desktop‐scale experiments, material point method simulation, and analytical theory uncover the fundamental mechanism of soft jumping robots.
