The optical-transport properties of 1D Se-doped CdS nanostructures with different doping contents and/or crystallization degrees are reported. The locally excited photoluminescence shows a significant redshift during the transport along the long axis of the 1D structures and can leave enough PL intensity for detection. The magnitude of the redshift is found to be highly dependent on the content...

Local drug delivery has received much recognition in recent years, yet it is still unpredictable how drug efficacy depends on physicochemical properties and delivery kinetics. The purpose of the current study is to provide a useful mathematical model for drug release from a drug delivery device and consecutive drug transport in biological tissue, thereby aiding the development of new therapeuti...

Friction in ordered atomistic layers plays a central role in various nanoscale systems ranging from nanomachines to biological systems. It governs transport properties, wear and dissipation. Defects and incommensurate lattice constants markedly change these properties. Recently, experimental systems have become accessible to probe the dynamics of nanofriction. Here, we present a model system co...

A combination of ab initio simulations and linear-scaling Green’s functions techniques is used to analyze the transport properties of long (up to one micron) carbon nanotubes with realistic disorder. The energetics and the influence of single defects (monoand di-vacancies) on the electronic and transport properties of single-walled armchair carbon nanotubes are analyzed as a function of the tub...

After the discovery of the high-Tc superconducting oxides, many strongly correlated 3d electron systems have been reinvestigated. Recently, perovskite-type manganese oxides (R,A)MnO3 have been studied extensively. The above group of materials exhibit colossal magnetoresistance (MR) at the carrier doped region, which is interesting not only from the standpoint of strongly correlated systems but ...

The exceptionally high mobility of carriers in graphene is one of its defining characteristics, especially in view of potential applications. Therefore it is of both practical and fundamental importance to understand the mechanisms responsible for limiting the values of the mobility. The aim of the paper is to study theoretically one such mechanism, i.e. scattering on ripples. The transport pro...

We study the charge transport properties of fields confined to a (2+1)-dimensional defect coupled to (3+1)-dimensional super-Yang-Mills at large-Nc and strong coupling, using AdS/CFT techniques applied to linear response theory. The dual system is described by Nf probe D5or D7-branes in the gravitational background of Nc black D3-branes. Surprisingly, the transport properties of both defect CFT...

The review introduces the reader to a theoretical method describing the transport properties of dilute alloys on an ab initio basis. The calculations start from density or spin density functional theory using a Green function formalism to investigate the underlying electronic structure of the ideal and perturbed system on equal footing. The residual resistivity is calculated solving the quasicl...
