This paper aims to investigate the correlations between concentrations of nine heavy metals in moss and atmospheric deposition within ecological land classes covering Europe. Additionally, it is examined what extent statistical relations are affected by use around sampling sites. Based on data collected 2010/2011 throughout Europe total modelled two chemical transport models (EMEP MSC-E, LOTOS-EUROS), correlation coefficients were specified for spatial subsamples defined (ELCE) as a...
A new software StatThermo for calculation of thermodynamic functions using the molecular constants in Rigid Rotator – Harmonic Oscillator approximation has been developed. Program includes various prebuilt algorithms to calculate atom coordinates majority simple compounds (with a number atoms N ≤ 8). The developed can make two reference temperatures (0 or 298.15 K) and different pressures. One prominent features is taking into account low-lying electronic levels. was tested on organic...

A new approach to determine the work function for ionic crystals by Knudsen Effusion Mass Spectrometry was suggested. The method successfully tested on alkali halide metals MX (M = Na, K, Rb, Cs; X F, Cl, Br, I).
A multi-technique approach based on Knudsen effusion mass spectrometry, gas phase chromatography, NMR and IR spectroscopy, thermal analysis, quantum-chemical calculations was used to study the evaporation of 1-butyl-3-methylimidazolium tetrafluoroborate (BMImBF4). The saturated vapor over BMImBF4 shown have a complex composition which consisted neutral ion pairs (NIPs) [BMIm+][BF4-], imidazole-2-ylidene C8N2H14BF3, 1-methylimidazole C4N2H6, 1-butene C4H8, hydrogen fluoride HF, boron...
In this work, comprehensive investigations of l- and dl-methionine have been conducted by the methods differential scanning calorimetry (DSC), Knudsen effusion mass spectrometry (KEMS), quantum chemistry. Heat capacities crystalline were measured DSC in temperature range 209–473 K their thermodynamic functions (TFs) determined. The structures molecular parameters 29 gaseous conformers computed framework DFT theory (B3LYP/cc-pVTZ) TFs methionine ideal gas state obtained. Sublimation was...

The crystal–vapor equilibrium for the standard amino acids l-serine and l-cysteine was studied by Knudsen effusion mass spectrometry in temperature ranges of 387–442 361–429 K, respectively. At these relatively low temperatures, surface degradation samples shown to be minor. vapor pressure obtained method used calibrate spectrometer. dependence investigated range is described a linear equation ln(p/Pa) = −(18.227 ± 289)/T + (39.828 0.593) −(16.658 270)/T (38.295 0.806) l-cysteine. set...
