Extremely anisotropic scintillations [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
A small number of quasars exhibit interstellar scintillation on time-scales less than an hour; their scintillation patterns are all known to be anisotropic. Here we consider a totally anisotropic model in which the scintillation pattern is effectively one-dimensional.

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.

Inhibition of canalicular and sinusoidal taurocholate efflux by cholestatic drugs in human hepatoma HepaRG cells

open access: yesBiopharmaceutics &Drug Disposition, Volume 43, Issue 6, Page 265-271, December 2022., 2022
Effects of cholestatic drugs towards hepatic canalicular and sinusoidal secretion of bile acids were investigated using a biphasic functional assay in human hepatoma HepaRG cells. After an initial loading phase with taurocholate, cells were re‐incubated in taurocholate‐free medium (efflux phase), with or without calcium (for modulating the opening of ...

A Sustainable Route From Quartz to Bifunctional Material with Adsorbed Lanthanides for Enhanced Fluorescent Activation in Doxycycline Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
The aim of this study is to develop a sensor material based on natural quartz combined with La(III) and Ce(III), both detected in Ni‐MH batteries, as well as Eu(III), for reliable qualitative and quantitative analysis of doxycycline over a broad concentration range.

GOLD plasma bubble observations comparison with geolocation of plasma irregularities by back propagation of the high-rate FORMOSA7/COSMIC 2 scintillation data

open access: yesFrontiers in Astronomy and Space Sciences
Using the high-rate phase and amplitude scintillation data from FORMOSA7/COSMIC two mission and back-propagation method, we geolocate plasma irregularities that cause scintillations.

3D Printing of Scintillating Materials [PDF]

open access: yesarXiv, 2014
We demonstrate, for the first time, the applicability of 3D printing technique to the manufacture of scintillation detectors. We report of a formulation, usable in stereolithographic printing, that exhibits scintillation efficiency on the order of 30\% of that of commercial polystyrene based scintillators.

Leveraging Grain Boundary Effects for Nanostructured Electrode Layers in Symmetric Solid Oxide Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Nanocrystalline thin‐films of lanthanum chromite exhibit extraordinary properties of fast oxygen kinetics. These properties are due to the peculiar chemistry of grain boundaries and can be harnessed for fabricating symmetric electrochemical devices with self‐healing properties. Abstract While grain boundary engineering is attracting great interest as a

GPS TEC, scintillation and cycle slips observed at high latitudes during solar minimum [PDF]

open access: yesAnnales Geophysicae, 2010
High-latitude irregularities can impair the operation of GPS-based devices by causing fluctuations of GPS signal amplitude and phase, also known as scintillation.

Development of novel plastic scintillators based on polyvinyltoluene for the hybrid J-PET/MR tomograph [PDF]

open access: yesarXiv, 2017
A novel plastic scintillator, referred to as J-PET scintillator, has been developed for the application in the digital positron emission tomography (PET). The novelty of the concept lies in application of the 2-(4-styrylphenyl)benzoxazole as a wavelength shifter. To date, the chemical compound has not been used as scintillator additive.

PMT calibration of a scintillation detector using primary scintillation [PDF]

open access: yesJournal of Instrumentation, 2015
We have studied the calibration of PMTs in scintillation detectors, inducing single electron response on the PMT from primary scintillation produced by x-ray interaction. The results agree with those obtained by the commonly used single electron response (SER) method, which uses LED light pulses to induce the PMT SER.
