A review on the numerical simulation of equatorial plasma bubbles toward scintillation evaluation and forecasting

open access: yesProgress in Earth and Planetary Science, 2017
Equatorial plasma bubbles (EPBs) have been a longstanding and increasingly important subject because they cause severe scintillations in radio waves from Global Navigation Satellite System satellites.

Visible and Infrared Dual‐Band Camouflage Device Using Reflective Display Technology

open access: yesAdvanced Materials Technologies, EarlyView.
Integrating electrochromic devices and electrophoretic display technologies has led to developing a flexible dual‐band camouflage device. The system enables adaptive modulation across visible and near‐infrared spectra through pixel‐level control, rapid switching, and bistable operation.

Advances in Halide Perovskites for Photon Radiation Detectors

open access: yesAdvanced Materials Technologies, EarlyView.
This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

From Photo‐Damage to Self‐Healing in Thin Film Pb‐Iodide Perovskites: Action at a Distance

open access: yesAdvanced Optical Materials, Volume 13, Issue 19, July 4, 2025.
Fluorescence imaging uncovers pronounced spatial and temporal changes in photoluminescence of halide perovskite films following laser‐induced damage. Modifications spatially extend well beyond the illuminated region and evolve over distinct time scales ranging from seconds to many hours, revealing material‐specific self‐healing pathways. These findings

A method for scintillation characterization using geodetic receivers operating at 1 Hz

open access: yesJournal of Geodesy, 2017
Ionospheric scintillation produces strong disruptive effects on global navigation satellite system (GNSS) signals, ranging from degrading performances to rendering these signals useless for accurate navigation. The current paper presents a novel approach

Atmospheric scintillation in astronomical photometry [PDF]

open access: yes, 2015
Scintillation noise due to the Earth's turbulent atmosphere can be a dominant noise source in high-precision astronomical photometry when observing bright targets from the ground. Here we describe the phenomenon of scintillation from its physical origins
