Popis:	Both gas phase Na n and Na n (NaOH) 2 nanoparticle ensembles ( n = 50–250) are produced in a gas aggregation source and studied by using laser-ionization time-of-flight mass spectrometry. Heterogeneous Na n (NaOH) 2 clusters are shown to be produced by accretion of sodium atoms on nucleation centers initially formed by a chemical reaction between H 2 O and Na or Na 2 molecules. Mass distributions are compared for Na n grown on an homogeneous nucleation center and for Na n (NaOH) 2 developing on an heterogeneous seed in the same condensation source, allowing the comparison between homogeneous and heterogeneous clustering efficiency.
