2023 - English
NIVB Meeting 2023 – the second meeting of the National Institute of Virology and Bacteriology (NIVB) in Kutná Hora on 2. 10. – 5. 10. 2023 will be again after one year an opportunity to meet the participating teams, discuss excellent science, establish collaborations, and present the progress of the project to the members of the International Scientific Advisory Board. Thanks to funding from the Czech Economic Recovery Plan, a number of important results have already been published in high impact journals. Several networking workshops have been organized and scientific collaborations have been established. The meeting in Kutná Hora is therefore a summary of all that has happened in the project over the past year. The main goal of the NIVB is to facilitate cooperation between 30 participating research teams from 8 Czech research institutions, and this goal is gradually being achieved. The NIVB acts as a common communication platform to discuss the desired cooperation of the NIVB research teams, especially those that have not had much contact so far due to their inter-institutional, interdisciplinary or inter-regional distance.\nWe thank all the participants who contributed to the meeting with 30 oral presentations and 67 posters. The NIVB 2022 meeting had the ambition to launch a new series of annual meetings dedicated to virology and bacteriology, and NIVB 2023 fulfils this ambition and continues to aim to inform the wider scientific community about new developments, trends and issues in these disciplines.

3D Printed Microfluidic Cell for Spectroelectrochemical Analysis
Šikula, M.; Vaněčková, Eva; Hromadová, Magdaléna; Kolivoška, Viliam
2023 - English
Recent advances in fused deposition modeling 3D printing (FDM 3DP) enabled \nthe manufacture of customized spectroelectrochemical (SEC) devices. Despite significant progress, \nreported designs still rely on conventional optical components (windows and cuvettes). In this \nwork, we apply bi-material FDM 3DP combining electrically conductive and optically \ntranslucent filaments to manufacture a fully integrated microfluidic SEC device. Employing cyclic \nvoltammetric measurements with redox probes, we demonstrate that the platform allows SEC sensing of \nreactants, intermediates, and products of charge transfer reactions in an oxygen- free \nenvironment. Developed approaches pave the way for SEC d vices with dramatically\nreduced costs compared to currently available commercial platforms.\n Keywords: spectroelectrochemistry; three-dimensional printing; fused deposition modeling Available on request at various institutes of the ASCR

Electrochemical Properties of Mixed Self-Assembled Monolayers Based on Terpyridine Transition Metal Complexes
Kocábová, Jana; Nováková Lachmanová, Štěpánka; Vavrek, František; Valášek, M.; Hromadová, Magdaléna
2023 - English
This work presents the electrochemical characterization of mixed self-assembled monolayers\n(SAMs) of [Os(terpy)2]2+ and terpyridine connected by tripodal anchoring groups to the\npolycrystalline gold bead electrode and provides a comparison with SAM based on\n[Os(terpy)2]2+ tripodal molecules without diluting terpyridine tripodal molecules. It is shown\nthat both arrangements enable reproducible preparation of well-defined compact films. The\nelectron transfer rate constant for mixed SAM was determined from cyclic voltammograms\naccording to Laviron’s analysis and compared with the rate constant obtained previously for\nSAM containing only [Os(terpy)2]2+ tripod.

Elimination Voltammetry with Linear Scan: Advantages and Disadvantages
Navrátil, Tomáš; Trnková, L.; Hrdlička, Vojtěch; Li, X.
2023 - English
Elimination voltammetry with linear scan (EVLS) represents an almost traditional\nmathematical method that helps to obtain additional and detailed information about the recorded\nelectrochemical signals and therefore, to better understand the analyzed systems. Although it\nhas been substantially developed and expanded during its existence of more than a quarter of a\ncentury and has found many areas of application, like any other mathematical and experimental\nmethod, it exhibits several advantages and disadvantages. In this contribution, we summarize\nits strengths, weaknesses, opportunities, as well as threats.\n Keywords: elimination voltammetry with linear scan; advantages; disadvantages Available on request at various institutes of the ASCR

Mathematical Modeling of Heat and Mass Transfer in a Rotary Kiln
Kozakovič, M.; Čada, J.; Kokavcová, A.; Havlica, Jaromír; Huchet, F.
2022 - English
The main objective of this research was to compare the results of the proposed 1D transport model with numerical simulations of mass transport in a direct-heat rotary kiln at laboratory scale. Another objective was to investigate the effect of the number of flights on the formation of an active particle surface in the airborne phase, which enables efficient heat transport. The studied rotary kiln is a low-angle cylinder with a length of 0.5 meter and a diameter of 0.108 meter with regularly arranged flights on the inside. The heat is transported into the rotary kiln by hot air at the inlet. The load in the rotary kiln consists of spherical particles with 1 millimeter diameter. The rotary kiln rotation speed is 21.5 rpm. For each simulation, 20 rotations were performed. The Discrete Element Method implemented in an open-source code LIGGGHTS was used for simulations.Efficient heat transfer is made possible primarily by the large number of particles in the airborne phase, which are heated by the warm air blowing in. To begin with, the number of flights and their geometry were found to be a key parameter controlling the amount of particles in the gaseous regime. It was also found that an area in the right part of the base of the cylinder is formed which is not reached by particles from the flights. This phenomenon is due to the dynamics of particle transport, as the particles are not maintained in the active phase and move rapidly towards the load due to gravity. In conclusion, the effect of this zone is negative, as hot air flows through it without resistance, preventing the system from heating effectively.

Electrochemical Techniques in Monitoring of Nervous System Drugs
Choińska-Mlynarczyk, Marta; Hrdlička, Vojtěch; Skopalová, J.; Šelešovská, R.; Kolivoška, Viliam; Navrátil, Tomáš
2022 - English
Drugs of the nervous system (ATC group N) belong generally to the most commonly (mis)used substances worldwide. Their determination and monitoring of these drugs and their metabolites in various body fluids or environmental matrices represent a challenge for analytical chemists. Our research is focused on the application of electrochemical methods in the monitoring of the most frequently prescribed and the newly introduced nervous system drugs of precisely specified structures and/or of defined properties. For toxicological and pharmacokinetic reasons, emphasis has been placed on investigating the reaction mechanisms of their metabolite formation. New or alternative to commonly used electroanalytical methods applicable for monitoring and characterization of target compounds in their pure state, in body fluids, wastewaters, and other environmental matrices, has been developed. To improve the chemometric parameters and sensing characteristics, attention was paid to the construction of new electrochemical sensors, detectors (e.g. screen-printed, 3D printed), or cells, based on (modified/unmodified) traditional or nontraditional materials, preferably usable at the point-of-care.
