Publikováno v: Journal of Physics and Chemistry of Solids. 68:701-706

Nitrogen-doped diamond-like carbon (DLC) layers (a-C:H:N, N-DLC or DLN) were prepared by the plasma-enhanced chemical vapor deposition (PECVD) technique, using a RF capacitive discharge (13.56 MHz), at low pressures (20 Pa), produced from a mixture o

Comment on ‘TenS4+ (n= 1–4) clusters in the gas phase’ by D.M. David Jaba Singh and T. Pradeep [Chem. Phys. Lett. 417 (2006) 34]

Autor: Milan Alberti, Zbyněk Špalt, Josef Havel

Publikováno v: Chemical Physics Letters. 429:638-641

Isotopic pattern of TeS 4 + species as published by Singh and Pradeep does not correspond to the declared TeS 4 + but to the Te 2 + cluster. Furthermore, most of the other species declared as having been formed in the gas-phase have already been publ

Laser desorption/ionization and laser ablation synthesis of new selenium oxide compounds from selenium(IV) dioxide

Autor: Milan Alberti, Zbyněk Špalt, Eladia María Peña-Méndez, Josef Havel

Publikováno v: Rapid Communications in Mass Spectrometry. 20:1019-1024

Laser desorption/ionization (LDI) and/or laser ablation (LA) of selenium dioxide crystals or its mixtures with sodium peroxide were studied using a commercial matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometer. I

Publikováno v: Polyhedron. 24:1417-1424

Arsenic clusters Asn (n = 2−7) were generated from elemental arsenic using laser ablation on a commercial matrix assisted laser desorption ionization – time of flight (MALDI-TOF) mass spectrometric instrument. Singly charged As n + clusters were

Publikováno v: Rapid Communications in Mass Spectrometry. 19:3405-3410

Laser desorption/ionisation and laser ablation of solid selenium trioxide, as well as the gas-phase behaviour of selenium trioxide, were studied. Selenium trioxide undergoes photochemical decomposition and, from the mass spectra obtained by laser des
