“…This effect is well known for the nanoclusters of different types, e.g. for C [20], Ar [21], Na [21], and for nanoclusters of II-VI semiconductors [22,23]. Our first-principles calculations [16] have shown that such stable nanoclusters exist for ZnP 2 .…”

CdP 2 nanoclusters were fabricated by incorporation into pores of zeolite Na-X and by laser ablation. Absorption and photoluminescence (PL) spectra of CdP 2 nanoclusters in zeolite were measured at the temperatures of 4.2, 77 and 293 K. Both absorption and PL spectra consist of two bands blue shifted with respect to bulk crystal. We performed the calculations aimed to find the most stable clusters in the size region up to size of the zeolite Na-X supercage. The most stable clusters are (CdP 2 ) 6 and (CdP 2 ) 8 with binding energies of 9.30 eV and 10.10 eV per (CdP 2 ) 1 formula unit respectively. Therefore, we attributed two bands observed in absorption and PL spectra to these stable clusters. The Raman spectrum of CdP 2 clusters in zeolite was explained to be originated from (CdP 2 ) 6 and (CdP 2 ) 8 clusters as well. The PL spectrum of CdP 2 clusters produced by laser ablation consists of the asymmetric band with low-energy tail that has been attributed to emission of both (CdP 2 ) 8 cluster and CdP 2 microcrystals.

“…Consequently, to modernise and update Schrödinger's original question involves research in size-dependent biology relating to what is called 'nano-science'. Indeed, the observation has already been made [22] that an inert cluster and a living virus can be of comparable size, which in itself raises interesting issues about the difference between them both.…”

Abstract. The question is asked: what are new size-dependent effects characteristic of the nanoscale range which justify considering 'dynamics on the nanoscale' as a scientific area in its own right rather than merely an extension of existing knowledge to a different parameter range. A preliminary list of such effects is drawn up. It is shown to include many challenging unsolved problems as well as a number of fundamental investigations which are more or less advanced in development at the present time.

“…One would have in mind that the free energy of formation of small undercritical clusters depends on the cluster structure, which can differ even for the same cluster size (Bromley & Illas, 2007;Connerade, 2002;Ong & Tok, 2007). It is known that the so-called magic numbers of clusters correspond to the local minimum of the cluster energy in the dependence of their size.…”
