1. A New Synthetic Route and Comprehensive Topological Study of a Benzimidazole Derivative
Benzimidazole and its derivatives are molecules that have diverse biological properties, therefore we synthesized and studied a new benzimidazole to understand their physical/chemical properties. The compound was obtained through a new synthetic route, using graphite oxide, in the absence of solvent, with crystalline packaging supported by C-H…N and C-H…

2. Estudio de estructuras de cis- y trans-estilbeno mediante microscopiade fuerza atómica
ABSTRACTNanotechnology is a multidisciplinary field that emerged in recent years due to the development of tools to "see", study and manipulate matter at atomic and molecular levels. Stilbene and some of its derivatives are organic molecules found in nature, which have chemical structures of interest in nano-fabrication of molecular machine building blocks (

3. Estudo cristaloquímico de quatro derivados fenazínicos utilizando a difração de raios-X.
In general, natural and synthetic phenazines have attracted much attention because of their biological activities, like antitumour agents antimalarials, antibiotics, among others. The natural phenazines are isolated as secondary metabolites of terrestrial and marine microorganisms, mainly of Pseudomonas spp. and Streptomyces spp. This work aiming the structu

4. NOVAS ABORDAGENS ANALÍTICAS PARA A DETERMINAÇÃO DE CICLOFENIL POR FLUORIMETRIA APÓS DERIVAÇÃO FOTOQUÍMICA E PARA AS DETERMINAÇÕES VOLTAMÉTRICAS DE ESTROBILURINAS UTILIZANDO O ELETRODO DE MERCÚRIO E DE CD (II), CU (II) E PB (II) UTILIZANDO O ELETRODO DE FILME DE BISMUTO / NEW ANALYTICAL APPROACHES FOR SPECTROFLUORIMETRIC DETERMINATION OF CYCLOFENIL AFTER PHOTOCHEMISTRY DERIVATION AND FOR STROBILURIN VOLTAMMETRIC DETERMINATION USING MERCURY ELECTRODE AND CU (II) VOLTAMMETRIC DETERMINATION USING BISMUTH FILM ELECTRODE
In this work, analytical approaches for the selective determinations of cyclofenil, stroblilurins (azoxystrobin and dimoxystrobin) and Cu (II) have been developed. The determination of cyclofenil was made by taking advantage of their fluorescent photoderivative. In order to achieve maximum fluorescence (250/410), the best conditions for derivatization and fo

5. Graphite Functionalized in Conditions of Friedel-Crafts Reaction mediated by Radiation of Microwave: New Material for Construction of Electrodes of Carbon Paste / Grafite funcionalizada em condições de Friedel-Crafts mediada por radiação de microondas: novo material para construção de eletrodos de pasta de carbono
Modification and/or functionalization of eletrodic materials have been investigated in order to improve the application of chemically modified electrode (CME) regards on their sensitivity, selectivity and reactivity comparing with unmodified substrate. However, the stability and reproducibility of these CME are one of the most important goals to achieve main

6. ASSESSMENT OF THE DEGRADATION OF OIL IN MANGROVE SEDIMENT: STUDY CASE, GUANABARA BAY / AVALIAÇÃO DA DEGRADAÇÃO DE ÓLEO EM SEDIMENTOS DE MANGUEZAL: ESTUDO DE CASO, BAÍA DE GUANABARA, RJ
Brazil is observing an increasing growth in the petroleum industry resulting in an equally increased risk of accidents involving petroleum and derivatives. A great part of the Brazilian coastal plain is covered by mangroves, which are an important ecosystem for procreation and preservation of marine and terrestrial species. As a result it is urgent the need
