Melting in metallic Sn nanoparticles studied by surface Brillouin scattering and synchrotron-x-ray diffraction

Melting profile of cesium metal nanoclusters by molecular dynamics simulation

“…Tel. : +98 711 613 7353; fax: +98 711 228 6008. melting point decreases with the decrease in the cluster size [10]. However for small clusters with sizes less than 1-2 nm, the monotonic relation of melting temperature with the size of the cluster is lost.…”

Physical properties of elongated inorganic nanoparticles

“…Generally, melting of nanoparticles starts at their surfaces. Experimental techniques used to observe the melting of nanoparticles include for example X-ray [609,610] and electron diffraction [608,611,612], calorimetry [613], femtosecond laser spectroscopy [614] and surface Brillouin scattering [615]. Several reports have shown that samples of metal nanorods made of same material, but differing from each other in terms of average diameters and lengths, have dissimilar melting points.…”

Impurity effect on the melting of nickel clusters as seen via molecular dynamics simulations

“…Such a size effect on the melting temperature of small metal clusters having diameters down to 2-3 nm has been confirmed in a series of experiments. [6][7][8][9] However for clusters having sizes smaller than 1-2 nm, the melting temperature is no longer a monotonic function of the cluster size. Experiments on sodium clusters Na N , with number of atoms N = 50-360, have demonstrated that melting temperature as a function of size shows a prominent irregular structure with the local maxima.…”
