Correlating experimental electrochemistry and theoretical calculations in 2 '-hydroxy chalcones: the role of the intramolecular hydrogen bond
(Royal Soc Chemistry, 2015)
In this work we present a study on the molecular structure and electrochemical behavior of a
series of methoxylated 2'-hydroxychalcones, whose antitumor activity has been previously
described. Cyclic voltammetry was used ...
Evidence of the Disassembly of alpha-Cyclodextrin-octylamine Inclusion Compounds Conjugated to Gold Nanoparticles via Thermal and Photothermal Effects
(MDPI, 2016)
Cyclodextrin (CD) molecules form inclusion compounds (ICs), generating dimers that are capable of encapsulating molecules derived from long-chain hydrocarbons. The aim of this study is to evaluate the structural changes ...
Peculiar features of the low‐latitude and midlatitude ionospheric response to the St. Patrick's Day geomagnetic storm of 17 March 2015
(American Geophysical Union, 2016-07-25)
The current study aims at investigating and identifying the ionospheric effects of the geomagnetic storm that occurred during 17–19 March 2015. Incidentally, with SYM‐H hitting a minimum of −232 nT, this was the strongest ...
Aplicação do efeito Mossbauer ao estudo de propriedades físicas do sistema ZrxTi1-xFe2
(Universidade Federal de Minas GeraisUFMG, 1985-03-14)
Using Espectrospecopia Mossbaur and diffraction of X-rays, we studied the physical properties of ZrxTi1-xFe2.Foram pseudo-binary system prepared 15 samples at concentrations of 0.00 <x <1,00.As analysis of measurement ...
Complexos carbonílicos de rutênio. De um gás tóxico a uma droga com potencial agente citotóxico
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2007-11-27)
In this work ruthenium carbonyl complexes were synthesized and characterized which allowed an interesting spectroscopic and structural study as well as preliminary in vitro antitumor activity assays. Thus, the interests ...
Estudo da atividade eletrocatalítica de multicamadas metálicas de Ir/Pt e Cu/Pt eletrodepositadas sobre Pt(policristalina) para eletrooxidação de moléculas orgânicas pequenas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2013-09-26)
The search for alternative energy sources stead fossil fuel has driven the development of new energy generating devices. Among these, the Direct Alcohol Fuel Cells are a kind of device that directly convert chemical energy ...
A solid-state NMR study of the structure and dynamics of the myristoylated N-terminus of the guanylate cyclase-activating protein-2
(Elsevier ScienceAmsterdam, 2010-02)
Guanylate cyclase-activating protein-2 (GCAP-2) is a retinal Ca2+ sensor protein. It plays a central role in shaping the photoreceptor light response and in light adaptation through the Ca2+-dependent regulation of the ...
YebC, a putative transcriptional factor involved in the regulation of the proteolytic system of Lactobacillus
(Nature Publishing Group, 2017-12-17)
The proteolytic system of Lactobacillus plays an essential role in bacterial growth, contributes to the flavor development of fermented products, and can release bioactive health-beneficial peptides during milk fermentation. ...
