Ecotoxicity assessment of functionalized activated charcoal on the activity of the enzyme acetylcholinesterase and its effect in the presence of pesticides. Author(s): VIANNA, M.; NOVOTNY, E. H.; SILVA, T. S.; RIBEIRO, B. R.; DITTZ, L. A. The study of soil organic matter of the "Terras Pretas de Índios" showed an efficient compost model for improving the physical chemistry properties of the soil. The charred materials have the condense... ... Repository: BDPA Publication year: 2014
Effect of different culture tube caps and concentrations of activated charcoal and sucrose on in vitro growth and budding induction of Annona glabra L. Author(s): SANTANA, J. R. F. de; PAIVA, R.; SOUZA, A. V. de; OLIVEIRA, L. M. de The present work evaluated the effects of different types of culture flask seals and varying concentrations of sucrose and activated charcoal on the in vitro induction and growth of buds of Annona gla... ...

Chemical functionalisation of actived charcoal - Reproducing the Terra Preta de Índios organic matter model. Author(s): LINHARES, C. R.; LEMKE, J.; AMARAL, N.; AUCCAISE, R.; NOVOTNY, E. H. erras Pretas de Índios are anthropogenic soils found in the Amazon which have high carbon content, high fertility and high resilience. These characteristics are due to the pyrogenic character of their... ... Repository: BDPA Publication year: 2010

Panorama atual da produção de carvão vegetal no Brasil e no Cerrado. Author(s): DUBOC, E.; COSTA, C. J.; VELOSO, R. F.; OLIVEIRA, L. S.; PALUDO, A. ABSTRACT: The charcoal production from planted forests has been insufficient to take care of the demand and has implied in more pressure on the forest remainders, in special of the biome Cerrado. In 2... ... Repository: BDPA Publication year: 2007
Chemical composition of humic acids extracted from soils influenced by ancient charcoal production in Rio de Janeiro - Brazil. Author(s): RODRIGUES, A. F.; NOVOTNY, E. H.; OLIVEIRA, R. R. During the late nineteenth century, some areas in Rio de Janeiro - Brazil - has undergone remarkable transformation of the forest arising from ancient charcoal activity carried out by ex-slaves. Nowad... ... Repository: BDPA Publication year: 2014
Spectroscopic investigation on the effects of biochar and soluble phosphorus on grass clipping vermicomposting. Author(s): NOVOTNY, E. H.; BALIEIRO, F. de C.; AUCCAISE, R.; BENITES, V. de M.; COUTINHO, H. L. da C. Seeking to evaluate the hypothesis that biochar optimises the composting and vermicomposting processes as well as their product quality, we carried out field and greenhouse experiments. Four grass cli... ... Repository: BDPA Publication year: 2022
Chemical oxidation of Eucalyptus benthamii charcoal. Author(s): ALHO, C. F.; NOVOTNY, E. H.; MAIA, C. M. B. de F.; LIMA, E. A. de; HANSEL, F. A.
