In this work, we probe anion production upon electron interaction with Fe(CO)5 clusters using two complementary cluster-beam setups. We have identified two mechanisms that lead to synthesis of complex anions with mixed Fe/CO composition. These two me

The latest achievements are presented in experimental and theoretical studies of resonance scattering of low-energy (0–15-eV) electrons from molecular targets in a gas phase resulting in the formation and decay of negative ions. The focus is on dis

Plant hormones (PHs) are signalling molecules produced within plants that influence plant growth, seed germination, fruit maturation and ripening and pathogen defence [1,2]. Hence, the quantitative analysis of the PHs and determination of their conce

Ion mobility spectrometry (IMS) equipped with a corona discharge (CD) ion source was used for measurement of three auxin plant hormones including indole-3-acetic acid (IAA), indole-3-propionic acid (IPA), and indole-3-butyric acid (IBA). The measurem
