The standard practice in calculation and laboratory exercises often involves students working with the same dataset. While this simplifies process, it also creates a significant opportunity for academic dishonesty, such as plagiarism, may resort to using others’ work or results. This undermines intended learning outcomes. Additionally, there is tendency of use measurement data from real world which presents some challenges, particularly terms providing large volume diverse datasets due...
The Mini Labyrinth experiment is a neutron and gamma shielding currently being developed at the Slovak University of Technology, Bratislava (STU). STU consists NEUTRONSTOP blocks, water tank, PuBe source, graphite prism. This article describes second construction version presents newest results fields’ simulation measurement. source with emission rate 1.06E7 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math...
One of the most effective ways gaining user experience and minimizing effects on modelling simulation is benchmarking. Currently (2022) a new experimental workplace, so called 'Mini Labyrinth' being developed at Slovak University Technology in Bratislava (STU). It simple neutron gamma shielding benchmark, inspired by ALARM-CF-AIR-LAB-001 ICSBEP experiment. The latest V2 setup consists PuBe source, several NEUTRONSTOP C5 blocks, H2O filled polylactic acid (PLA) tank, plastic source holder...
Laboratory exercises are an important part of the teaching process at many faculties. However, despite fact that today implementation laboratory is carried out on modern equipment, full potential equipment often not used, is, some possibilities fully used in student practice. In paper, it will be shown two cases from practice how user experience can expanded by using exactly those „forgotten“ options. first case, a solution based use Standard Commands for Programmable Instruments (SCPI),...
The use of sensors in the development laboratory equipment is widespread, and today there hardly any modern device that does not rely on some form sensor technology. Sensors are selected to meet specific characteristics a given process. In selection process, certain dominant features typically considered; however, also often overlooked, yet they can significantly impact realization desired functionalities equipment. This paper highlights these aspects through practical example.
Due to its unique material properties, such as extreme hardness and radiation resistance, silicon carbide has been used an important construction for environments with conditions, like those present in nuclear reactors. As such, it is constantly exposed energetic particles (e.g., neutrons) consequently subjected gradual crystal lattice degradation. In this article, the 6H-SiC damage simulated by implantation of 4 MeV C3+ ions (0001) axial direction a single ion fluences 1.359 1015 cm-2,...
The Mini Labyrinth experiment is a simple neutron and gamma shielding developed at STU, inspired by the ALARM-CF-AIR-LAB-001 ICSBEP benchmark experiment, originally constructed in former Soviet Union 1982. Compared to original Labyrinth, which was made from concrete blocks had dimension of several meters, STU approximately ten times smaller consists NEUTRONSTOP blocks. purpose this validate computer codes partners involved APVV-DS international project "Experimental simulation studies...

In this paper the influence of thermal reduction on oxygen functional groups graphene oxide, synthesized by modified Hummer's method, has been investigated. The oxide was characterized X-ray diffraction analysis, ultraviolet-visible spectroscopy, scanning and transmission electron microscopy. Atomic force microscopy used for thickness analysis layers before after reduction. Changes in surface thermally reduced were monitored temperature programmed desorption method (TPD). TPD samples showed...
Abstract Ion beam irradiation is a versatile tool for structural modification and engineering of new materials. In this study, 12‐tungstophosphoric acid (WPA) films different thickness were spin‐coated on platinized silicon substrate irradiated with low energy hydrogen ions (10 keV) swift heavy (Bi, Xe, V) energies up to 710 MeV. The energy/fluence combinations allowed controllable changes that investigated in detail using Raman Infrared spectroscopy. For 120‐nm‐thick WPA samples, the led...
This paper presents the electrochemical properties of graphene-oxide composites and nanoparticles cobalt-ferrite, as well cobalt-ferrite doped with zinc gallium. Graphene-oxide (GO) was synthesized by a modified Hummer's method. The magnetic were solvothermal method, after which oleic acid exchanged dihydrocaffeic to obtain hydrophilic material.
