Dielectric function of two-phase colloid–polymer nanocomposite

A simple two-phase environment model is used to calculate localized plasmon resonances in effective media, beyond the limit of homogeneous media.

Physicochemical characterization of nanoparticles and their behavior in the biological environment

Whilst the physical and chemical properties of nanoparticles in the gas or idealized solvent phase can nowadays be characterized with sufficient accuracy, this is no longer the case for particles in the presence of a complex biological environment.

The role of defects in the nonlinear optical absorption behavior of carbon and ZnO nanostructures

In bulk materials, defects are usually considered to be unwanted since deviations from perfect lattices may degrade device performance.
