The effect of an external magnetic field on electrical impedance was measured on tris-(8-hydroxyquinoline) aluminum (Alq3) based OLEDs at different temperatures. Magnetic field effects (MFEs) were responsible for significant ...

Analytical modeling of p-i-n solar cells constitutes a practical tool to extract electronic material and device parameters from fits to experimental data and to establish optimization criteria. This paper proposes a model ...

In one-dimensional systems, the dynamics of a Brownian particle are governed by the force derived from a potential as well as by diffusion properties. In this work, we obtain the first-passage-time statistics of a Brownian ...

The stochastic drift-diffusion (DrDiff) theory is an approach used to characterize the dynamical properties of simulation data. With new features in transition times analyses, the framework characterized the thermodynamic ...

We examine bivariate extensions of Aït-Sahalia’s approach to the estimation of univariate diffusions. Our message is that extending his idea to a bivariate setting is not straightforward. In higher dimensions, as opposed ...

A cell/microreactor is develop and fully characterized to perform diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) experiments to investigate heterogeneously catalyzed surface reactions. The experimental ...

Materiais e dispositivos baseados em compostos orgânicos desempenham um importante papel em diversas áreas da aplicação tecnológica devido às suas interessantes propriedades eletro-magneto- ópticas, adicionadas às suas ...
