Luminescence of the CsZrCl under High Pressure.

The photoluminescence (PL) and Raman spectra of the CsZrCl crystal over a wide range of pressures were studied in this work for the first time. PL measurements were performed up to 10 GPa, while the Raman spectra were measured up to 20 GPa. The PL data revealed a linear blue shift of the emission maximum from about 2.

Simultaneous Measurement of the Half-Life and Spectral Shape of ^{115}In β Decay with an Indium Iodide Cryogenic Calorimeter.

Current bounds on the neutrino Majorana mass are affected by significant uncertainties in the nuclear calculations for neutrinoless double-beta decay. A key issue for a data-driven improvement of the nuclear theory is the actual value of the axial coupling constant g_{A}, which can be investigated through forbidden β decays. We present the first measurement of the 4th-forbidden β decay of ^{115}In with a cryogenic calorimeter based on indium iodide.

Measurement of the 2νββ Decay Half-Life of ^{82}Se with the Global CUPID-0 Background Model.

We report on the results obtained with the global CUPID-0 background model, which combines the data collected in the two measurement campaigns for a total exposure of 8.82  kg×yr of ^{82}Se. We identify with improved precision the background sources within the 3 MeV energy region, where neutrinoless double β decay of ^{82}Se and ^{100}Mo is expected, making more solid the foundations for the background budget of the next-generation CUPID experiment.

Features of Electrochemical Hydrogen Pump Based on Irradiated Proton Exchange Membrane.

An electrochemical hydrogen pump (EHP) with a proton exchange membrane (PEM) used as part of fusion cycle systems successfully combines the processes of hydrogen extraction, purification and compression in a single device. This work comprises a novel study of the effect of ionizing radiation on the properties of the PEM as part of the EHP. Radiation exposure leads to nonspecific degradation of membranes, changes in their structure, and destruction of side and matrix chains.

Bis(thienyl)ethenes with α-methoxymethyl groups. Syntheses, spectroscopic Hammett plots, and stabilities in PMMA films.

A series of bis(thienyl)ethenes (BTEs) possessing perfluorocyclopentene backbones and methoxymethyl groups (MOM) in the 2/2'-positions of the thiophenes was prepared and examined. The substitution pattern of the 5/5'-positions was varied, covering the range from electron-donating to electron-withdrawing. The substituent effects of the absorption wavelengths of the ring-opened and the ring-closed isomers, which are interconverted by reversible 6π-electrocyclizations and cycloreversions, are studied by means of the spectroscopic Hammett equation and the Hammett-Brown equation.

Final Result on the Neutrinoless Double Beta Decay of ^{82}Se with CUPID-0.

CUPID-0, an array of Zn^{82}Se cryogenic calorimeters, was the first medium-scale demonstrator of the scintillating bolometers' technology. The first project phase (March 2017-December 2018) allowed the most stringent limit on the neutrinoless double beta decay half-life of the isotope of interest, ^{82}Se, to be set. After a six month long detector upgrade, CUPID-0 began its second and last phase (June 2019-February 2020).

Growth, structure, and temperature dependent emission processes in emerging metal hexachloride scintillators CsHfCl and CsZrCl.

Crystals of metal hexachlorides CsMCl (M = Hf or Zr) have recently emerged as promising materials for scintillation applications due to their excellent energy resolution. In this work, we investigated the crystal structure and scintillation properties of CsHfCl and CsZrCl crystals in the broad temperature range from 9 to 300 K. X-ray diffraction data confirmed the same cubic structure (space group ) for CsHfCl and CsZrCl over the entire examined temperature range.

Background identification in cryogenic calorimeters through delayed coincidences.

Localization and modeling of radioactive contaminations is a challenge that ultra-low background experiments are constantly facing. These are fundamental steps both to extract scientific results and to further reduce the background of the detectors. Here we present an innovative technique based on the analysis of delayed coincidences in Th and U decay chains, developed to investigate the contaminations of the ZnSe crystals in the CUPID-0 experiment.

[Inguinal lymphadenitis due to invasion of Dirofilaria repens].

The paper presents the case of the right-sided inguinal inflammation of a lymph node as a result of invasion of Dirofilaria repens, the parasitic pathogen of subcutaneous dirofilariasis in animals of the canine family. The diagnosis was verified on the basis of the parallel application of morphological studies of cross sections of the nematode in histological samples and the molecular biological method polymerase chain reaction of scrapings of histological material. The localization of this helminth inside the cavities of the human body is extremely rare.

D. repens is the causative agent of subcutaneous dirofilariasis in canine animals. In recent years, human invasion by this vector-borne helminthiasis has been recorded in many countries with temperate climate, but the localization of this helminth in the cavities of the human body is extremely rare.

Characterization of vanadium of biological origin for possible applications in physics experiments.

For the first time, vanadium of biological origin, extracted from centrifugal fraction of vanadium-storing blood cells of the Ascidia sydneiensis samea species, was characterized as regards its isotopic composition and content of natural radioactive elements potassium (K), thorium (Th) and uranium (U). The natural abundance of vanadium isotopes has been confirmed with high accuracy, thus excluding a possible selectivity within bio-chemical reactions of vanadium concentration in blood cells from seawater. A large potassium concentration (up to 5500 × 10 g g) was found in the blood cell samples.
