DETERMINAÇÃO DE ESTRUTURAS CRISTALINAS A PARTIR DA DIFRAÇÃO DE RAIOS X EM POLICRISTAIS – UM CAMINHO VIÁVEL  

Prof. Dr. Alexandre Cuin

UFJF – Depto. Química

 Abstract:

A determinação e refinamento de estruturas cristalinas através da técnica de difração de Raios X em amostras policristalinas (SDPD – Structure Determination from Powder Diffraction data) teve uma grande expansão nas últimas décadas, possivelmente devido ao desenvolvimento de novos difratômetros, a trabalhos inovadores, como o de Young Rietveld entre outros, à disponibilidade de computadores e, também, ao desenvolvimento de softwares específicos para tratamento dos dados de raios X. Apesar desta expansão, ainda poucos grupos de pesquisa no mundo estão habilitados a desenvolver o trabalho em SDPD. No presente seminário, serão abordados alguns conceitos teóricos e, também, experimentais sobre SDPD no intuito de mostrar que a determinação de estruturas utilizando-se dados de difração de raios X de amostras policristalinas pode ser um caminho viável quando monocristais do material não são possíveis de serem obtidos para um determinado composto

Correlating Structural, Electronic and Ionic Diffusion Properties of Nanomaterials for Energy Storage 

Profª Drª Corinne Arrouvel / UFSCar – Sorocaba

 Abstract:

 The quest of new materials at the nanoscale is an important topic in the modern society. The industrial interest is to improve the energy conversion, the storage capacity and the kinetic of the electrochemical energy in high-technology devices. Materials should be in addition low cost, stable under a wide range of temperature and pressure conditions and safe. This talk will introduce basic concepts of electrochemistry, of bulk and surface properties in order to explain the difference of energy carrier transport mechanisms in rechargeable lithium batteries, capacitors, solid oxide fuel cells and solar cells. Combining computational and experimental techniques, we show that some key aspects are based on the search of optimized size and morphology of their nanocomponents. Anisotropic energy pathways and crystal shape will be therefore highlighted.

Nonperturbative QCD effects in forward scattering at LHC 

Prof. Emerson Gustavo de Souza Luna – IF/UFRGS

Abstract:

We study infrared contributions to semihard parton-parton interactions by considering an effective charge whose finite infrared behavior is constrained by a dynamical mass scale. Using an eikonal QCD-based model in order to connect this semihard parton-level dynamics to the hadron-hadron scattering, we obtain predictions for the proton-proton ($pp$) and antiproton-proton ($\bar{p}p$) total cross sections, $\sigma_{tot}^{pp,\bar{p}p}$, as well as for the ratios of the real to imaginary part of the forward scattering amplitude, $\rho^{pp,\bar{p}p}$. We discuss the theoretical aspects of this formalism and consider the phenomenological implications of a class of energy-dependent form factors in the high-energy behavior of the forward amplitude. Our results, obtained using a group of updated sets of parton distributions, are consistent with the recent data from the TOTEM experiment.
