Event‐Driven Elongation Monitor for Soft Devices Using a Deformation‐Activated Piezoconductive Switch

open access: yesAdvanced Materials Technologies, EarlyView.
A stretchable, event‐driven strain sensor with low energy consumption is developed using positive piezoconductive composites. These composites remain insulative when relaxed, while they become conductive when stretched. Their electrical characteristics are modifiable by the nickel's weight ratio and cross‐sectional geometry. Strain‐induced switching is

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,

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

A Resonant Beginning for the Solar System’s Terrestrial Planets

open access: yesThe Astrophysical Journal
In the past two decades, transit surveys have revealed a class of planets with thick atmospheres—sub-Neptunes—that must have completed their accretion in protoplanet disks.

Single and Bi‐Layer Glass‐Based Phantoms: Robust Materials for a Calibration Standard for Fluorescence Imaging Systems

open access: yesAdvanced Photonics Research, EarlyView.
Fluorescence‐guided surgery is a common technique and characterizing imaging performance is important to ensure clinical reliability. A calibration standard comprising multiple glass phantoms fabricated to mimic the optical properties of fluorescent and non‐fluorescent tissue is presented.

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
