Wide-band chalcogenide scintillators on the basis of AIIBVI compounds

Технологія та конструювання в електронній апаратурі, 2012
The formation characteristics of chalcogenide scintillators (CS) based on zinc sulfide and selenide are considered. The research has shown that such scintillators have high specific light yield, low afterglow level, short luminescence time, low value of ...

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

Advanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

Advanced Functional Materials, EarlyView.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Multi-frequency GNSS robust carrier tracking for ionospheric scintillation mitigation

Journal of Space Weather and Space Climate, 2017
Ionospheric scintillation is the physical phenomena affecting radio waves propagating from the space through the ionosphere to earth. The signal distortion induced by scintillation can pose a major threat to some GNSS application. Scintillation is one of

Interfacial Behavior of Methane in Methane/p‐Xylene/Water Systems: First Principles Inspected Using Neutron Imaging and Molecular Dynamics Simulations

Advanced Materials Interfaces, EarlyView.
Pressurized gases reduce interfacial tension (IFT) at the gas‐liquid interfaces, their influence on the liquid–liquid interfaces remains unclear. For model compounds methane, water, and p‐xylene, neutron imaging observation of pressurized three‐phase systems is combined with Molecular Dynamics simulations.

Solar Cycle Variations of GPS Amplitude Scintillation for the Polar Region

Space Weather, 2020
Global Positioning System (GPS) L1 amplitude data, obtained using the Canadian High Arctic Ionospheric Network (CHAIN) during the period 2008–2018, is used to study the seasonal and solar cycle dependence of high‐latitude amplitude scintillation.
