Ambient organic aerosol origin at rural background site in the Czech Republic
Lhotka, Radek
2022 - anglický
Source apportionment of organic aerosols (OA) at background sites is one of the important tasks of the current air quality protection. OA are emitted directly from primary sources or formed in the atmosphere via the oxidation of gas-phase precursors with subsequent partitioning resulting in low-volatility products into the particle phase.

2022 - anglický
This study assesses the variability of organic aerosol (OA) sources monitored at the rural background site Frýdlant. Non-refractory PM1 was evaluated in two seasons of\n2021. The positive matrix factorization with the multi-linear engine was used to determine the sources of OA at Frýdlant site, with four factors resolved both in winter and\nsummer.

An Improved Method for Calculation of the Wet Particle Diameter and tha Kappa Parameters from the CCN Data
Wagner, Zdeněk; Mishra, Gaurav; Moravec, Pavel; Zíková, Naděžda
2022 - anglický
The study of particle size distribution and hygroscopic growth is important for several reasons. Particle diameter is available experimentally, but the relationship of \nhygroscopic growth to cloud condensation nuclei (CCN) and AMS data can be modeled mathematically. In this paper, we present an improved algorithm for calculating the wet \nparticle diameter and the κ parameter that is faster, more accurate, and more reliable than the algorithm used by other authors.\n

Electrochemical Characterization of Self-Assembled Monolayers Containing Redox Switching Element
Nováková Lachmanová, Štěpánka; Kocábová, Jana; Vavrek, František; Sebechlebská, Táňa; Šebera, Jakub; Kolivoška, Viliam; Lukášek, J.; Balzer, N.; Valášek, M.; Hromadová, Magdaléna
2022 - anglický
Adsorption properties of molecules containing [Ru(terpy)2]2+ and [Os(terpy)2]2+ redox switching element connected to the electrode surface by tripodal thiolate anchoring groups have been studied together with their charge transfer properties in the adsorbed form. STM-based current-voltage measurements confirmed that the conductance of self-assembled monolayer containing [Os(terpy)2]2+ redox switching element is lower than that containing [Ru(terpy)2]2+ element. This observation agrees with previously observed differences in the electron transfer rate constants of these molecules in their adsorbed state.
