155. Laser ablation-single-particle-inductively coupled plasma mass spectrometry as a multimodality bioimaging tool in nano-based omicsDino Metarapi, Johannes Teun van Elteren, Martin Šala, Katarina Vogel-Mikuš, Iztok Arčon, Vid Simon Šelih, Mitja Kolar, Samo B. Hočevar, 2021, izvirni znanstveni članek Opis: Advanced data processing and visualization techniques were applied to laser ablation-single particleinductively
coupled plasma mass spectrometry (LA-sp-ICPMS) data obtained from imaging of roots of
sunflower (Helianthus annuus L.) which were exposed to ionic silver (Ag+). Highly multiplexed images with
tissue level resolution were generated, showing the uptake and transformation of Ag+ to silver
nanoparticles (AgNPs) in whole root cross-sections, and revealing that the size of biosynthesized AgNPs is
predisposed by the reducing power of particular root compartments. Various Ag+ and AgNP visualization
strategies are shown with special emphasis on spatially resolved information associated with the number
and spherical-equivalent size of individual AgNPs in user-selected root cross-sectional regions, including
statistical analysis of the AgNP distribution. Normally, this multimodality information can only be obtained
by combining the results of techniques from several complementary platforms. Ključne besede: Laser ablation, Ag XANES, bioimaging Objavljeno v RUNG: 03.06.2021; Ogledov: 2837; Prenosov: 51 Povezava na celotno besedilo Gradivo ima več datotek! Več... |
156. Neznanka, ki na odgovor še čaka2021, intervju Opis: Vprašanje, kako in kje nastajajo kozmični delci ekstremnih energij, je odprto že več kot petdeset let. Med najverjetnejšimi kraji njihovega nastanka sodijo aktivna galaktična jedra; to so središča galaksij, v katerih se skrivajo črne luknje, ki požirajo snov iz okolice. V raziskavah mednarodne kolaboracije Pierre Auger sodelujejo tudi slovenski raziskovalci z Univerze v Novi Gorici in Instituta Jožef Stefan.

160. Calibration of the underground muon detector of the Pierre Auger ObservatoryA. Aab, Andrej Filipčič, Jon Paul Lundquist, Samo Stanič, Marta Trini, Serguei Vorobiov, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2021, izvirni znanstveni članek Opis: To obtain direct measurements of the muon content of extensive air showers with energy above 10[sup]16.5 eV, the Pierre Auger Observatory is currently being equipped with an underground muon detector (UMD), consisting of 219 10 m[sup]2-modules, each segmented into 64 scintillators coupled to silicon photomultipliers (SiPMs). Direct access to the shower muon content allows for the study of both of the composition of primary cosmic rays and of high-energy hadronic interactions in the forward direction. As the muon density can vary between tens of muons per m[sup]2 close to the intersection of the shower axis with the ground to much less than one per m[sup]2 when far away, the necessary broad dynamic range is achieved by the simultaneous implementation of two acquisition modes in the read-out electronics: the binary mode, tuned to count single muons, and the ADC mode, suited to measure a high number of them. In this work, we present the end-to-end calibration of the muon detector modules: first, the SiPMs are calibrated by means of the binary channel, and then, the ADC channel is calibrated using atmospheric muons, detected in parallel to the shower data acquisition. The laboratory and field measurements performed to develop the implementation of the full calibration chain of both binary and ADC channels are presented and discussed. The calibration procedure is reliable to work with the high amount of channels in the UMD, which will be operated continuously, in changing environmental conditions, for several years.
