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

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

Endangered butterflies of lowland forests under climate change
Konvička, Martin; Beneš, Jiří; Číp, D.; Sobík, D.; Spitzer, L.; Faltýnek Fric, Zdeněk; Rindoš, Michal; Vrba, Pavel
2023 - Czech
The material compiles conservation measures and methods for the care of endangered butterflies of open forests, protected by the EU Habitat Directive in the Czech Republic and under climate changes. These species are Euphydryas maturna, Lopinga achine, Parnassius mnemosyne, Coenonympha hero, and partially also Zerynthia polyxena. It results from predictions of vegetational and climatic changes of forest habitats, and outlooks of forest and water management conditions. Metodika, shrnující zásady péče o populace hnědáska osikového (Euphydryas maturna), okáče jílkového (Lopinga achine), jasoně dymnivkového (Parnassius mnemosyne), okáče hnědého (Coenonympha hero) a částečně pestrokřídlece podražcového (Zerynthia polyxena), druhů světlých lesů chráněných Směrnicí o stanovištích EU, v podmínkách měnícího se klimatu. Vychází z predikcí vegetačních a mezoklimatických změn lesních biotopů, výhledů lesního hospodářství v ČR a vodohospodářských poměrů.
