Self-assembled nanoparticle superlattices-materials made of inorganic cores capped by organic ligands, of varied structures, and held together by diverse binding motifs-exhibit size-dependent properties as well as tunable collective behaviour arising

The response and properties of a dielectric nanodroplet with a 10 nm diameter made of formamide placed in a uniform electric field are explored with molecular dynamics simulations and an analytic free energy formulation. Increasing fields cause the i

We review the historical and modern understanding of the most basic equation of friction, Amontons' law, which describes phenomena that were already understood and studied by Leonardo da Vinci 500 years ago. This law states that for any two materials

Diffusion characteristics of gold clusters (consisting of 38, 79, 140, or 586 atoms) on two types of defective graphite surfaces, one with a one-layer deep hole and the other with a one-layer high step edge, are studied with the use of molecular dyna

Investigations of surface roughness effects on the structure, dynamics and rheology of a molecular fluid (hexadecane) confined between solid (gold) surfaces, through the use of large-scale molecular dynamics simulations, reveal a remarkable sensitivi

Size-evolutions of structural and spectral properties in two types of finite systems are discussed. First we focus on energetics and structures of gold clusters, particularly AuN in the 40≲N≲200 range exhibiting a discrete sequence of optimal clu

Anomalous diffusion of a gold nanocrystal Au{sub 140} , adsorbed on the basal plane of graphite, exhibiting L{acute e}vy-type power-law flight-length and sticking-time distributions, is predicted through extensive molecular dynamics simulations. An a

Investigations of the melting of gold nanocrystalline clusters, using molecular dynamics simulations, reveal that at elevated temperatures the melting process is punctuated by solid-to-solid structural transformations from the low-temperature optimal
