Journal ArticleDOI
Biosynthesis of gold nanoparticles using Pseudomonas aeruginosa.
TL;DR: Transmission electron microscopy (TEM) micrograph showed the formation of well-dispersed gold nanoparticles in the range of 15-30 nm and may lead to the development of an easy bioprocess for synthesis of Au NPs.
Journal ArticleDOI
Electrically tunable plasmonic behavior of nanocube-polymer nanomaterials induced by a redox-active electrochromic polymer

TL;DR: It is suggested that the combination of anisotropic nanostructures and electrochromic matrix has the potential to reversibly electrically tune plasmonic resonances over the full visible spectrum.
Journal ArticleDOI
A new catalytically active colloidal platinum nanocatalyst: the multiarmed nanostar single crystal.
TL;DR: High-resolution TEM shows that the nanostar has many arms, varying from a few to over 30, whereby even the largest ones are found to have single-crystal structures, which strongly suggests that they are formed by a growth mechanism of the seed crystals and not by the aggregation of seed crystals, which should produce twinning planes.
Journal ArticleDOI
Experimental evidence for the nanocage effect in catalysis with hollow nanoparticles.
TL;DR: Because of the nanoreactor confinement effect of the hollow nanocatalysts, the frequency factors obtained from the Arrhenius plots are found to be the highest ever reported for this reduction reaction.
Journal ArticleDOI
On the Use of Plasmonic Nanoparticle Pairs As a Plasmon Ruler: The Dependence of the Near-Field Dipole Plasmon Coupling on Nanoparticle Size and Shape †
TL;DR: The aim of the present paper is to use electron beam lithography and DDA calculations to examine the constancy of the exponential decay length value in the plasmonic ruler equation on particle size and shape of a number of particles including nanoparticles of different symmetry and orientations.
