  • Metal nanoparticles are certain to be the building blocks of the next generation of electronic, optoelectronic and chemical sensing devices. The physical limits imposed by top-down methods such as photo- and electron- beam lithography dictate that the synthesis and assembly of functional nanoscale materials will become the province of chemists.

  • Laser-induced thermal explosion of metallic nanoparticles originates from nonlinear optical effect. Nonlinear optical properties of nanoparticle materials depend strongly on their size and shape. Several methods were proposed to produce nanoparticles of a controlled size and welldefined distribution. We studied to prepare silver nanoparticles by laser ablation. The characteristic spectral feature of the silver nanoparticles (peak around 400nm) was found in the absorption spectra measured by a UV-Vis 2450 spectrometer. ...

  • This book consists of a collection of review chapters that summarize the recent progress in the areas of metal and semiconductor nanosized crystals (nanocrystals). The interest in the optical properties of nanoparticles dates back to Faraday’s experiments on nanoscale gold. In these experiments, Faraday noticed the remarkable dependence of the color of gold particles on their size. The size dependence of the optical spectra of semiconductor nanocrystals was first discovered much later (in the 1980s) by Ekimov and coworkers in experiments on semiconductor-doped glasses.

  • Catalysis and Electrocatalysis at Nanoparticle Surfaces reflects many of the new developments of catalysis, surface science, and electrochemistry. The first three chapters indicate the sophistication of the theory in simulating catalytic processes that occur at the solid–liquid and solid–gas interface in the presence of external potential. The first chapter, by Koper and colleagues, discusses the theory of modeling of catalytic and electrocatalytic reactions.
