Nanoparticle, size-dependent melting, quantum size effect, liquid drop model, Lindemann criterion, nuclear physics, quantum mechanics, materials chemistry.

Nanoparticle research is an exciting field. Serving as a linkbetween bulk materials and atoms, these materials, existingon a nanometre scale (10−9m), display some fascinating properties.One such property is the depression of melting point.As the particle size decreases, the melting temperature decreasesdramatically. This article describes a model explainingthe origin of this behaviour of nanomaterials (Figure 1).To reinforce the concept in the text and force the reader tothink carefully about the quantitative aspects, short problemshave been included in the end.
