Development and properties of cadmium and lead tungstate low-background scintillators for double beta decay experiments [PDF]

open access: yesÂderna Fìzika ta Energetika, 2014
Methods of deep purification of natural and isotopically enriched cadmium (Cd, 106Cd, 116Cd), as well as of archaeological lead (archPb), to produce cadmium and lead tungstate crystal scintillators have been developed. The basic stages of development and

Cherenkov and Scintillation Light Separation Using Wavelength in LAB Based Liquid Scintillator [PDF]

open access: yesJournal of Instrumentation. 14 (2019) 1-15, 2018
Linear alkyl benzene (LAB) has in recent years been used as a solvent for PPO in large-scale scintillation detectors, like Daya Bay and SNO+. The combination has several nice properties, including high light yield, good materials compatibility, and excellent pulse shape discrimination.

High‐Speed and Scalable Wet Spinning of Graphene/Liquid Crystalline Elastomer Composite Filaments

open access: yesAdvanced Functional Materials, EarlyView.
Polydomain filaments from graphene/liquid crystalline elastomer (LCE) composites are scalably‐manufactured by wet spinning across a wide range of diameters (≈137–1128 µm) at a speed up to 4500 m h−1 through a double diffusion coagulation mechanism, enabling fast actuation and optimized mechanical performance for broad applications.

Scintillation properties of Gd3Al2Ga3O12:Ce3+ single crystal scintillators [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2014
Abstract The scintillation properties of Gd 3 Al 2 Ga 3 O 12 :Ce 3+ (GAGG:Ce) single crystals grown by the Czochralski method with 1 at% cerium in the melt were investigated and results were compared with so far published results in the literature. The light yield (LY) and energy resolution were measured using a XP5200B photomultiplier.

Novel epoxy-bPBD-BisMSB composite plastic scintillator for alpha, beta and gamma radiation detection

open access: yesScientific Reports
A composite plastic scintillator is prepared by uniform dispersion of organic fluorophores 2-(4-Biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole (b-PBD) and 1,4-bis(2-methylstyryl) benzene (Bis-MSB) in epoxy resin followed by curing at room ...

Tribenzyl Organic Cations Carried Multidentate X‐Type Lewis Soft Base for High‐Performance Foldable Perovskite Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
This study proposes tribenzyl organic cation carried multidentate X‐type Lewis soft base to enhance adhesion and passivate defects simultaneously, aiming to achieve foldable and efficient perovskite nanocrystal‐based light‐emitting diodes. The resulting pure red F‐PeLEDs exhibit a recorded high EQE of 16.2% and robust mechanical properties to endure ...

Gold Nanoparticles and Their Alternatives for Radiation Therapy Enhancement

open access: yesFrontiers in Chemistry, 2014
Radiation therapy is one of the most commonly used treatments for cancer. The dose of delivered ionizing radiation can be amplified by the presence of high-Z materials via an enhancement of the photoelectric effect; the most widely studied material is ...

Ultrafast Superradiant Scintillation from Isolated Weakly Confined Perovskite Nanocrystals

open access: yesAdvanced Materials, EarlyView.
Efficiency and scintillation velocity are critical for high‐energy and medical physics. These parameters, typically conflicting in conventional scintillators, are simultaneously optimized by exploiting the giant oscillator strength of CsPbBr3 nanocrystals, leading to radiatively accelerated (multi)excitonic emission with unity efficiency without ...

Exploring Impacts of Surface Coatings to Modify Water Uptake and Selectivity within Metal–Organic Nanotubes

open access: yesAdvanced Materials Interfaces, EarlyView.
The surface of a metal–organic nanotube (MONT) is modified by a self‐assembled monolayer (ammonium trifluoroacetate) and polymer coatings, specifically polyvinylidene fluoride and polyacrylonitrile to explore their influence on water adsorption properties in hybrid materials.

Scintillating properties of frozen new liquid scintillators [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1999
Abstract The light emission from scintillators which are liquid at room temperature was studied in the interval between +20°C and −120°C where the phase transition from liquid to solid takes place. The light yield measured at −120°C is about twice as much as that observed at +20°C.
