The size and shape of nanoscale materials provide excellent control over many of the physical and chemical properties, including electrical and thermal conductivity, magnetic properties, luminescence, and catalytic activity (Lieber, 1998). In particular, the synthesis and morphological control of nanosized particles, which exhibit surprising and novel phenomena based on the unique property called the quantum size effect, are attractive to chemists and physicists (Alivisatos, 1996). In recent… 
IR femtochemistry on the surface of wide-gap ionic crystals
We have found and studied a phenomenon of the growth of films resulting from decomposition of some organic and silicon-containing molecules adsorbed on the surface of ionic crystals under the action
Plasmon mediated non-photochemical nucleation of nanoparticles by circularly polarized light
We predict nucleation of pancake shaped metallic nanoparticles having plasmonic frequencies in resonance with a non-absorbed circularly polarized electromagnetic field. We show that the same field

Manipulation of gold nanoparticles inside transparent materials.
TLDR
A method that can control the precipitation of Au nanoparticles in three dimensions inside transparent materials by using focused femtosecond laser irradiation is reported, implying that the laser can be used not only in practical applications, such as the 3D optical memory and the fabrication of integrated alloptical switches, but also in the study of the control of nucleation and crystal growth.

Photoinduced Conversion of Silver Nanospheres to Nanoprisms
TLDR
This light-driven process results in a colloid with distinctive optical properties that directly relate to the nanoprism shape of the particles, which could be useful in developing multicolor diagnostic labels on the basis of nanoparticle composition and size but also of shape.
Ultrashort pulse manipulation of ZnO nanowire growth.
TLDR
The overall results show that the pulse energy is critical for heterogeneous nucleation while the irradiation duration affects the density of nucleation, which together with the hydrothermal treatment temperature influence the growth rate and thus the morphology of the nanowires.
Nanobelts of Semiconducting Oxides
TLDR
The beltlike morphology appears to be a distinctive and common structural characteristic for the family of semiconducting oxides with cations of different valence states and materials of distinct crystallographic structures, which could be an ideal system for fully understanding dimensionally confined transport phenomena in functional oxides.
