Numerical analysis of the resistance behavior of an electrostatically-induced graphene double junction

We present a numerical approach that we have developed in order to reproduce and explain the resistance behavior recently observed, as a function of the backgate voltage and of the position of a biased scanning probe, in a graphene flake in which a double p-n junction has been electrostatically induced. A simplified electrostatic model has been adopted to simulate the effect of gate voltages on the potential landscape, assuming for it a slow variation in space and using a simple capacitive model for the coupling between the electrodes and the graphene sheet. The transport analysis has then been performed with a solution of the Dirac equation in the reciprocal space coupled with a recursive scattering matrix approach. The efficiency of the adopted numerical procedure has allowed us to explore a wide range of possible potential landscapes and bias points, with the result of achieving a good agreement with available experimental data

Estudos dos frutos e da polpa da bocaiuva extraída mecanicamente para a produção de biodiesel.

Procurando obter parâmetros que norteiem o processo da extração do óleo da polpa da bocaiuva para a produção de biodiesel, frutos da bocaiuva foram coletados durante a safra de 2008 na região de Corumbá (MS) e destinados para análise do teor de óleo na Embrapa Instrumentação Agropecuária. Order to obtain data to guide the process of extracting oil from the pulp of bocaiuva for the production of biodiesel, bocaiuva fruits were collected in the 2008 harvest in Corumbá (MS) and sent for analysis of oil content in the Embrapa Instrumentação Agropecuária
