Au@Ag Nanoparticles: Halides Stabilize {100} Facets
The Journal of Physical Chemistry Letters, 2013 Seed-mediated growth is the most efficient methodology to control the size and shape of colloidal metal nanoparticles. In this process, the final nanocrystal shape is defined by the crystalline structure of the initial seed as well as by the presence of ligands and other additives that help to stabilize certain crystallographic facets.

Estimation of Purcell factor from mode-splitting spectra in an optical microcavity
, 2011 We investigate scattering process in an ultra-high-Q optical microcavity coupled to subwavelength scatterers by introducing "splitting quality" Qsp, a dimensionless parameter defined as the ratio of the scatterer-induced mode splitting to the total loss ...
