Resonant excitation energy transfer in [Rh(bpy)3][NaCr(ox)3]ClO4

Resonant fluorescence line narrowing of the R1 line of the [Cr(ox)3]3− chromophore in [Rh(bpy)3][NaCr(ox)3]ClO4 at 1.6 K neither gives rise to the usual three-line pattern nor to spectral diffusion. Instead multi-line spectra with spacings equal to the zero-field splitting of the ground state are observed. This phenomenon is attributed to efficient non-radiative resonant energy transfer within the R1 line.

GESTÃO DE RELAÇÕES ESTRATÉGICAS INTERPESSOAIS NAS ALIANÇAS CORPORATIVAS (GRE): SINERGIA DE VALOR NA GESTÃO INTEGRADA DE RH

Este trabalho pretende apresentar e compreender o papel da gestão estratégica de pessoas, dentro de uma visão que contempla as relações interorganizacionais fora dos limites tradicionais de seu escopo nas empresas e expandidas além das dimensões formais e fronteiras que permeiam uma organização. Este estudo estabelece a importância e sistemáticas da gestão de atividades de RH, compartilhadas com a cadeia de valor externa, analisando-as nas práticas com os canais de distribuição junto aos clientes. Esta área organizacional é denominada pelo autor de GRE - Gestão das Relações Estratégicas. Baseando-se em uma pesquisa exploratória em 26 empresas, organizada a partir de cinco empresas nodais e seus canais de distribuição, utilizou-se a aplicação de um questionário de pesquisa com escala Likert e entrevistas pessoais semi-estruturadas junto aos gestores e profissionais de diversas áreas, bem como o tratamento estatístico dos dados com o programa SPSS, indicando a confirmação das questões de pesquisa relativas a GRE como sendo uma proposta de expansão das atividades do RH, focando em como se pode e devem entregar valor para a organização, para os aliados estratégicos, os investidores e fundamentalmente para os clientes.(AU)

Elettrodeposizione di catalizzatori a base di Rh su schiume e fibre metalliche di FeCrAlloy per la produzione di syngas

The preparation of structured catalysts active in the catalytic partial oxidation of methane to syngas, was performed by electrosynthesis of hydroxides on FeCrAlloy foams and fibers. Rh/Mg/Al hydrotalcite-type compounds were prepared by co-precipitation of metallic cations on the support and successive calcination. Electrochemical reactions have been studied during the electrodeposition by linear sweep voltammetry. The experiments were performed at supports immersed in KNO3, KCl, Mg2+ and Al3+ aqueous solutions, starting by different precursors (nitrate and chlorides salts) and modifying the Mg/A ratio. Rh/Mg/Al hydrotalcite-type compounds were deposited on metal foams by applying a -1.2V vs SCE potential for 2000s with a nitrate solution of 0.06M total metal concentration. Firstly it was studied the effect of Mg on the coating propierties, modifying the Rh/Mg/Al atomic ratio (5/70/25, 5/50/45, 5/25/70 e 5/0/95). Then the effect of the amount of Rh was later investigated in the sample with the largest Mg content (Rh/Mg/Al = 5/70/25 and 2/70/28).The results showed that magnesium allowed obtaining the most homogeneous and well adherent coatings, wherein rhodium was well dispersed. The sample with the Rh/Mg /Al ratio equal to5/70/25 showed the best catalytic performances. Decreasing the Rh content, the properties of the coating were not modified, but the catalytic activity was lower, due to a not enough number of active sites to convert the methane. The work on metal fibers focused on the effect of precursor concentration, keeping constant composition, potential and synthesis time at the values of Rh/Mg/Al =5/70/25, -1.2V vs SCE and 1000s. However fibers geometry did not allow to obtain a high quality coating, even if results were quite promising.

Sn@Pt and Rh@Pt core–shell nanoparticles synthesis for glycerol oxidation

The development and optimization of electrocatalysts for application in fuel cell systems have been the focus of a variety of studies where core–shell structures have been considered as a promising alternative among the materials studied. We synthesized core–shell nanoparticles of Sn x @Pt y and Rh x @Pt y (Sn@Pt, Sn@Pt2, Sn@Pt3, Rh@Pt, Rh@Pt2, and Rh@Pt3) through a reduction methodology using sodium borohydride. These nanoparticles were electrochemically characterized by cyclic voltammetry and further analyzed by cyclic voltammetry studying their catalytic activity toward glycerol electro-oxidation; chronoamperometry and potentiostatic polarization experiments were also carried out. The physical characterization was carried out by X-ray diffraction, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. The onset potential for glycerol oxidation was shifted in 130 and 120 mV on the Sn@Pt3/C and Rh@Pt3/C catalysts, respectively, compared to commercial Pt/C, while the stationary pseudo-current density, taken at 600 mV, increased 2-fold and 5-fold for these catalysts related to Pt/C, respectively. Thus, the catalysts synthesized by the developed methodology have enhanced catalytic activity toward the electro-oxidation of glycerol, representing an interesting alternative for fuel cell systems.

A novel method to determine new potent angiotensin inhibitor, azilsartan, in human plasma via micelle-enhanced spectrofluorimetry using cremophor RH 40

Purpose: To develop a micelle-enhanced spectrofluorimetric method for the assay of azilsartan (AZL) in bulk form and spiked human plasma without the need for derivatization procedure. Method: The proposed method was based on studying the fluorescence behavior of AZL in Cremophor RH 40 (Cr RH 40) micellar system. The fluorescence intensity was measured at 371 nm after excitation at 264 nm. The proposed procedure was validated according to International Council on Harmonization (ICH) guidelines. Results: In aqueous solution, the fluorescence intensity of AZL was greatly enhanced by more than 3- fold in the presence of Cr RH 40. The fluorescence –concentration plot was linear over the range of 10 – 500 ng.mL-1, with a limit of detection of 3.287 ngmL-1. The proposed method was successfully applied to the determination of AZL in pure powder form and spiked human plasma. The mean recovery of AZL in spiked human plasma using the proposed method was 90.54 ± 1.17 %. Conclusion: The suggested method is highly sensitive and simple, and can easily be applied for the quantification of AZL in pure powder form as well as in biological fluids such as plasma.

Studio della reattività di cluster carbonilici di Rh con sali di Au(I)

Il progetto di tesi si è focalizzato sullo studio della reattività del cluster carbonilico [Rh7(CO)16]3- in presenza del sale Au(Et2S)Cl. Ogni reazione investigata è stata svolta in atmosfera controllata di CO, modificando i rapporti stechiometrici tra il precursore e il sale di Au(I) in diversi solventi. Inizialmente si è tentato di riprodurre la sintesi del cluster bimetallico [Rh20Au7(CO)45]5- già noto, utilizzando Au(Et2S)Cl. Si è poi amplificato lo studio con l’obiettivo principale di sintetizzare nuovi cluster bimetallici ad alta nuclearità. È stato ottenuto un composto nuovo analizzato tramite diffrattometria ai raggi X a cristallo singolo: [Rh22Au3(CO)x]n-. Tramite i dati cristallografici è stato possibile definirne la sola struttura metallica, e nonostante i diversi tentativi, il composto non ha prodotto cristalli migliori per una completa caratterizzazione. Viste le quantità significative di sottoprodotti a bassa nuclearità ottenute nelle reazioni studiate, parallelamente sono state condotte prove di recupero del rodio in quanto metallo prezioso. Infine, è stato ottimizzato un metodo per separare due specie già note con carica negativa simile, [Rh10Au(CO)26]3- e [Rh16Au6(CO)36]4-. Tutti i composti sono stati caratterizzati tramite spettroscopia IR, mentre sul nuovo cluster è stata effettuata anche un’analisi alla spettrometria di massa.
