Measurement of Krypton-85 in samples of atmospheric with Quantulus 1220 device without using a liquid scintillator [PDF]

arXiv, 2015
The possibility of measuring the 85Kr activity with a liquid scintillation spectrometer (LSS) by registering the scintillations in krypton was investigated. It was found that at partial pressure of krypton less than atmospheric, the conversion efficiency of krypton scintillators amounts to 3 keV/photon and is 20 times lower than the conversion ...

Development of Carbon‐11 Labeled Pyrimidine Derivatives as Novel Positron Emission Tomography (PET) Agents Enabling Brain Sigma‐1 Receptor Imaging

Advanced Science, EarlyView.
Novel carbon‐11 labeled pyrimidine derivatives are developed as PET imaging probes for visualizing sigma‐1 receptors in the brain. [11C]CNY‐01 demonstrates superior brain uptake and binding specificity in both rodents and non‐human primates. The study reveals decreased sigma‐1 receptor expression in Alzheimer's disease, offering a promising tool for ...

Isotope Techniques in Chemical Wastewater Treatment: Opportunities and Uncertainties

Angewandte Chemie, EarlyView.
In this review, we would first introduce basic knowledge about isotopic compounds and then scrutinize the physical and chemical influence induced by isotope changes. Special attention will be paid to the uncertainties in explaining the isotope results.

The field of view of a scintillator pair for cosmic rays [PDF]

arXiv, 2016
Particles in an extended air shower (EAS), initiated by a cosmic ray primary, lead to two nearly simultaneous detections in a scintillator pair. The angle of the EAS and the axis through both scintillators can be reconstructed using the time difference of the detections and the distance between the scintillators. The acceptances of a scintillator along

A Review of Ga₂O₃ Heterojunctions for Deep‐UV Photodetection: Current Progress, Methodologies, and Challenges

Advanced Electronic Materials, EarlyView.
This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges

Degradation of Glyphosate to Benign N‐Formyl Glycine Using MOF‐808 Nanocrystals

Angewandte Chemie, EarlyView.
A Zr‐based metal–organic framework (MOF‐808) with different crystal sizes and designed defect sites was employed as an efficient heterogeneous catalyst for the complete degradation of glyphosate at room temperature. The degradation mechanism produces N‐formyl glycine and hydroxymethyl‐phosphonate. Abstract Glyphosate (N‐phosphonomethyl glycine, GPh) is

Simulation Study for the Energy Resolution Performances of Homogenous Calorimeters with Scintillator-Photodetector Combinations [PDF]

arXiv, 2018
The scintillating properties of active materials used in high energy and particle physics experiments play an important role regarding the performances of both calorimeters and experiments. Two scintillator materials, a scintillating glass and an inorganic crystals were examined to be used for collider experiments showing good optical and scintillating

High Resistivity of Single Crystal CsPbBr3 Semiconductor for Radiation Detection via Proposed Temperature‐Concentration Balance Method

Advanced Electronic Materials, EarlyView.
This study introduces a temperature‐concentration balance (TCB) method to grow high‐quality CsPbBr₃ single crystal with improved phase purity and structural stability. The crystals exhibits a sharp emission peak at 527 nm, narrow full width at half maximum (21.1 nm), and high resistivity (up to 3.97 × 10¹⁰ Ω·cm).

The Scintillating Grid Illusion

Vision Research, 1997
Disk-shaped luminance increments were added to the intersections of a Hermann grid consisting of medium grey bars on a black background. Illusory spots, darker than the background, were perceived as flashing within the white disks with each flick of the eye. This striking phenomenon may be referred to as the scintillating grid illusion.

SSLG4: A Novel Scintillator Simulation Library for Geant4 [PDF]

arXiv
This study introduces a new Scintillator Simulation Library called SSLG4 for the Geant4 Monte Carlo simulation package. With SSLG4, we aim to enhance efficiency and accelerate progress in optical simulations within the Geant4 framework by simplifying scintillator handling and providing a rich repository of scintillators.
