Ce3+:Lu3Al5O12–Al2O3 optical nanoceramic scintillators elaborated via a low-temperature glass crystallization route

Journal of Advanced Ceramics, 2023
Transparent Ce:lutetium aluminum garnet (Ce:Lu3Al5O12, Ce:LuAG) ceramics have been regarded as potential scintillator materials due to their relatively high density and atomic number (Zeff).

A new technique for infrared scintillation measurements [PDF]

, 2017
open7siWe propose a new technique to measure the infrared scintillation light yield of rare earth doped crystals by comparing it to near UV–visible scintillation of a calibrated Pr:(Lu0.75Y0.25)3Al5O12 sample.

The ionosphere prediction service prototype for GNSS users

Journal of Space Weather and Space Climate, 2019
The effect of the Earth’s ionosphere represents the single largest contribution to the Global Navigation Satellite System (GNSS) error budget and abnormal ionospheric conditions can impose serious degradation on GNSS system functionality, including ...

The Impact of Crystal Light Yield Non-Proportionality on a Typical Calorimetric Space Experiment: Beam Test Measurements and Monte Carlo Simulations

Instruments, 2022
Calorimetric space experiments were employed for the direct measurements of cosmic-ray spectra above the TeV region. According to several theoretical models and recent measurements, relevant features in both electron and nucleus fluxes are expected ...

Orthovanadate nanoparticles delay the accelerated aging in rats via the prevention of oxidative disturbances

Доповiдi Нацiональної академiї наук України
The abilities of gadolinium orthovanadate nanoparticles (GdVO4 : Eu3+ NPs, 8x25 nm) to ameliorate age-related lesions have been studied. To achieve the goal, a model of accelerated aging due to postnatal overfeeding (POF) was used.

Bulk NaI(Tl) scintillation low energy events selection with the ANAIS-0 module [PDF]

, 2014
Dark matter particles scattering off some target nuclei are expected to deposit very small energies in form of nuclear recoils (below 100 keV). Because of the low scintillation efficiency for nuclear recoils vs.

Comparison of Low‐Latitude Ionospheric Scintillation Forecasting Techniques Using a Physics‐Based Model

Space Weather, 2021
The temporal change in height of a specific electron density can be used as a proxy for vertical plasma drift (PVPD) at the magnetic equator. The use of PVPDs as a predictor of low‐latitude ionospheric scintillation during the subsequent evening has ...
