The synthesis of a family of para-substituted pyridine di(imine) ligands, and their corresponding iron dihalide, dicarbonyl and dinitrogen complexes are described. The influence of the substituents on the electronic structure of each derivative was investigated using a combination of X-ray diffraction, cyclic voltamme…
Lead by the theory of Transformation Optics and developments in metamaterials, the field of complex structures is growing in importance in the scientific community.In optics, those concepts add design flexibility to graded-index devices, but fabrication of high refractive index contrasts at the nanometer scale is stil…
The dielectric behavior of poly(vinyl alcohol) –PVA– crosslinked hydrogels obtained by the repeated freezing/thawing (F/T) technique have been investigated by dielectric relaxation spectroscopy (DRS) and differential scanningcalorimetry (DSC). The crosslinked polymer is produced by the clustering of chains caused by t…

O principal objetivo deste estudo foi conduzir uma investigação na performance da argila organofílica Brasgel como adsorvente no processo de remoção de metais pesados (zinco, chumbo e zinco/chumbo). Este trabalho foi realizado em 2 etapas; a primeira etapa consistiu em preparar a argila Brasgel organofílica, partindo-…
The clay mineral vermiculite was modified by intercalation of ethylenediamine (en) in acidic medium based on a 24 factorial design, the selected variables were: temperature of the intercalation reaction, concentration of en+, time under stirring and acid leaching of the vermiculite. Sixteen different experimental cond…
In this work CdMoO 4 nanoparticles were obtained under hydrothermal conditions using microwave radiation (2.45 GHz) (MH) at 100°C for different times. These powders were analyzed by X-ray diffraction (XRD), Field-emisson gum scanning electron microscopy (FEG-SEM), Ultraviolet-visible (UV-vis) absorption spectroscopy a…
There are many exotic properties of the charmonium and charmoniumlike states above $D\bar{D}$ threshold. The recent experimental results from BaBar and Belle on the new and conventional charmonium states are reviewed in this talk.
We have generated a number of compound data sets and programs for different types of applications in pharmaceutical research. These data sets and programs were originally designed for our research projects and are made publicly available. Without consulting original literature sources, it is difficult to understand sp…

Abstract. This first part of Special Session 5 explored the current status of infrared-based observations of obscured and distant stellar clusters in the Milky Way galaxy. Recent infrared surveys, either serendipitously or using targeted searches, have uncovered a rich population of young and massive clusters. However…
This text is an introduction to the study of NIP (or dependent) theories. It is meant to serve two purposes. The first is to present various aspects of NIP theories and give the reader the background material needed to understand almost any paper on the subject. The second is to advertise the use of honest definitions…
The mechanism of depinning process of vortex domain wall (DW) in a planar magnetic nanowire with an asymmetric notch is investigated by using focused magneto-optical Kerr effect (MOKE) magnetometer and micromagnetic modeling. Two distinct depinning fields are directly observed by the single-shot MOKE measurements. Mic…
The objective of this paper is to investigate the behaviour of laminated fibrereinforced composite plates subject to large deformations by developing a shell finite element and to predict the failure by illustrating the critical elements of the model. The laminates are assumed to be orthotropic and the first order she…
We systematically investigate the stability, electronic and magnetic properties of bimetallic benzene-ligand organic sandwich clusters, BzVBzTMBz (TM=Sc, Ti, Cr-Ni, Bz=C 6 H 6 ) and their one-dimensional infinite molecular wires, [BzVBzTM] , by employing spin-polarized density functional theory calculations. The BzVBz…

A new single element phase transition memory with a gate insulator composed of a phase transition film and two silicon dioxide layers is proposed. A phase transition thin film is placed between silicon dioxide layers and hence the gate stack of the transistor has a metal -insulator -phase transition material -insulato…
Parameters of molecular reactivity (PRM´s) have been used, to quantify atomic and molecular properties that can influence in the interactions among the molecules, in the synthesis of chemists compounds of interest in research and possible applications. In this work we observed that the order of the ligands basicicity…
