(Universidade Federal de Santa MariaBrasilRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia FlorestalCentro de Ciências Rurais, 2017-02-22)
Fumiculture is an activity of great economic importance in the South of Brazil and requires annually a large volume of forest biomass used in the curing process of tobacco leaves and accounting for almost 10% of production ...
Use of copper plate electrode and Pd catalyst to the nitrate reduction in an electrochemical dual-chamber cell
(Elsevier, 2020-06)
Nitrate is a chemical species usually present in water, lakes and rivers and in high concentration can be dangerous to the human health. In this work, palladium-coated alumina pellets associated to a copper plate electrode ...
Infrared Spectroscopy of Carbonaceous-chondrite Inclusions in the Kapoeta Meteorite: Discovery of Nanodiamonds with New Spectral Features and Astrophysical Implications
(IOP Publishing, 2018-03-22)
We report the finding of nanodiamonds, coexisting with amorphous carbon, in carbonaceous-chondrite (CC) material from the Kapoeta achondritic meteorite by Fourier-transform infrared (FTIR) spectroscopy and micro-Raman ...
