The performance of new sensors or advanced electrochemical energy storage devices strongly depends on the active materials chosen to realize such systems. In particular, their morphology may greatly influence their overall macroscopic properties. Frequently, limitations in classical ways of chemical preparation routes hamper the development of materials with tailored properties. Fortunately, su...

the overall aim of this study is to calculate some water properties in the single wall carbon naotubes (swcnt) and compare them to the bulk water properties to investigate the deviation of water properties inside the swcnt from those in the bulk. here some physical and transport properties of water molecules in the single wall carbon nanotube were reported by performing molecular dynamics (md) ...

It is demonstrated that electric transport in Bi-defi cient Bi 1− δ FeO 3 ferroelectric thin fi lms, which act as a p-type semiconductor, can be continuously and reversibly controlled by manipulating ferroelectric domains. Ferroelectric domain confi guration is modifi ed by applying a weak voltage stress to Pt/ Bi 1− δ FeO 3 /SrRuO 3 thin-fi lm capacitors. This results in diode behavior in macr...

We describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. We present a new method for computing, electronic transport wave function and Greens function of the disordered Graphene. In this method, based on the small rectangular approximation, break up the potential barriers in to small parts. Then using the f...

Here, we collect two parts of a research project on the pedestrian flow modeling. Rapid growth in the volume of public transport and the need for its reasonable, efficient planning have made the description and modeling of transport and pedestrian behaviors as important research topics in the past twenty years. First, we present a macroscopic model for the pedestrian flow based on continuum mec...

Abstract Nanoscale manipulation and characterization of individual molecules is necessary to understand the intricacies molecular structure, which governs phenomena such as reaction mechanisms, catalysis, local effective temperatures, surface interactions, charge transport. Here we utilize Raman enhancement between two nanostructured electrodes in combination with direct transport measurements ...
