(Pergamon-elsevier Science LtdOxfordInglaterra, 2008)
Acidentes provocados por Millipede com manifestacoes dermatologicas: Relatos de dois casos
This study is based on the two case reports of accidents provoked by arthropods (Millepede) in human beings. The authors present this type of accident, the insect specie that caused the accidents, the aggressive mechanism, ...
Understanding the influence of Lewis acids in the regioselectivity of the Diels–Alder reactions of 2-methoxy-5-methyl-1,4-benzoquinone: A DFT study
(Elsevier B.V., 2009-03-03)
The mechanisms of the Diels–Alder (DA) reactions of 2-methoxy-5-methyl-1,4-benzoquinone 1 with 2- methyl-1,3-butadiene 2, in the absence and in the presence of LA catalysts, have been studied using the DFT method at the ...
Experimental and Theoretical Study of the High-Temperature UV-Visible Spectra of Aqueous Hydroquinone and 1,4-Benzoquinone
(American Chemical Society, 2016-10)
UV-visible spectroscopic studies of aqueous hydroquinone (HQ) and 1,4-benzoquinone (BQ) have been carried out along with classical molecular dynamics (MD) and quantum calculations. The experimental results confirmed that ...
Aniline-1,4-benzoquinone as a model system for the characterization of products from aniline oligomerization in low acidic media
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Increase in the pH medium of aniline polymerization is used for giving products of different morphologies, which are often wrongly attributed to PANI chains. Infrared and Raman spectroscopic data, supported by quantum ...
