Forming alloys with impurity elements is a routine method for modifying the properties of
metals. An alternative approach involves the incorporation of interfaces into the crystalline …

Melting of solids is a common phenomenon in nature. It is also one of the most important
phase transformations in materials science and engineering. In recent years, extensive …

In the 1990s, nanoparticles and quantum dots began to be used in optical, electronic, and
biological applications. Now they are being studied for use in solid-state quantum …

A simple model for the size-dependent amplitude of the atomic thermal vibrations of a
nanocrystal is presented which leads to the development of a model for the size dependent …

Homogeneous nucleation kinetics for melting in superheated crystals is analyzed in order to
derive a kinetic stability limit for the crystal lattice above its equilibrium melting point (T m). It …

Recent unambiguous experiments (melting of ultrafine particles, premelting at the surface of
a bulk crystal, superheating, etc.) offer clear evidence of the key role of the surface in …

A unified model, free of any adjustable parameters, for the size-dependence and dimension-
dependence of melting point depression and superheating of nanocrystals is developed. In …

Precipitation-strengthening at ambient and high temperatures is examined in Al-0.5 Mn-0.3
Si (at.%) alloys with and without 0.02 at.% Sn micro-additions. Isochronal aging experiments …

Nanocalorimetry was used to investigate the melting of Bi nanoparticles. The particles were
formed by evaporating Bi onto a silicon nitride substrate, which was then heated. The …

The abbreviation “nano-Calphad” stands for “Calculation of Phase Diagrams for nano-
systems.” Nano-systems contain at least one phase or at least one interface layer (film …
