2008 journal article

Interfacial and solvent effects govern the formation of tris(dibenzylidenacetone)dipalladium(0) microstructures

LANGMUIR, 24(15), 7803–7809.

By: D. Leonard n, M. Cerruti n, G. Duscher n & S. Franzen n 

TL;DR: The formation of a majority of rods or hexagonal platelets in solution was shown to be determined by the ratio of THF to H(2)O in the solvent, whereas supersaturation effects and interfacial surface tension played a major role in creating the shape of particles formed upon evaporation of Pd(2)(DBA)(3) droplets on a surface.

TL;DR: The infrared emissivity of Au and silica-coated Au nanoparticles (Au NPs) deposited on indium tin oxide substrates was investigated and differences in temperature before and after laser irradiation were found to be directly proportional to the number of particles present on the slide and to the laser power used in the experiment.
