Velikostní efekt při fázovém přechodu v aerosolových systémech s nanočásticemi (klastry)
Levdansky, V.V. ; Smolík, Jiří ; Moravec, Pavel
It is shown that the dependence of the condensation coefficient on the particle size influences the trapping coefficient of vapor molecules by growing particles (clusters), critical size of aerosol particles and the rate of homogeneous nucleation.
Velikostní efekty při koalescenci nanorozměrných aerosolových částic
Levdansky, V.V. ; Smolík, Jiří ; Moravec, Pavel
The size effects in coalescence of nanoparticles related to the influence of the particle size on the surface tension, the activation energy for diffusion of atoms in particles and the sticking probability of particles were considered.
Vliv velikostního efektu, rezonančního záření a povrchových procesů na kritický průměr aerosolových částic
Levdansky, V.V. ; Smolík, Jiří ; Moravec, Pavel
The influence of size effect, resonance radiation and surface processes on the critical size of aerosol particles is considered theoretically. The joint effect of an adsorbable foreign gas and a difference in the condensation and evaporation coefficients is discussed.
Příprava nanočástic CuOx z acetylacetonátu měďnatého
Moravec, Pavel ; Smolík, Jiří ; Klementová, Mariana ; Levdansky, V.V.
Copper and copper oxide particles have a wide field of applications as catalysts, sensors, semiconductors, etc. In this work, we studied CuOx nanoparticle synthesis by metal organics chemical vapor deposition (MOCVD) using copper acetylacetonate (CuAA) as a precursor.

Moravec, Pavel ; Smolík, Jiří ; Keskinen, H. ; Mäkelä, J.M. ; Bakardjieva, Snejana ; Levdansky, V.V.
This article deals with preparation of Ni/NiOx nanoparticles from nickel acetylacetonate.
Synthesis of Heterostructure Particles by CVD Method in a Tube Flow Reactor
Moravec, Pavel ; Smolík, Jiří ; Levdansky, V.V. ; Keskinen, H.
Powders of mixed or heterostructure fine particles are of even greater value than the single component ones. During last decade we prepared single component fine particles of silica, alumina, titania and zirconia by decomposition of organoelement precursors in an externally heated tube flow reactor. On the basis of experience with the synthesis of single component particles we prepared mixed or coated multicomponent particles Al2O3-SiO2, TiO2-SiO2 and ZrO2SiO2 by simultaneous decomposition of two precursors in one reactor.
Vliv uspořádání vstupní sekce na tvorbu ZrO2 nanočástic tepelným rozkladem zirkonium terc-butoxidu v průtočném trubkovém reaktoru
Moravec, Pavel ; Smolík, Jiří ; Levdansky, V.V. ; Keskinen, H. ; Mäkelä, J. M.
In this work we present more comprehensive study of the particle generation from ZTBO with special emphasis on the influence of inlet section arrangement on formation and characteristics of particles.
