Solid-state 13C NMR studies of activated carbons prepared from biomass using different chemical agents. Author(s): NOVOTNY, E. H. Activated carbons are largely employed in several chemical and physical processes nowadays, including water treatment, catalysis, gas storage and others [1]. The surface properties of the porous carbo... ... Repository: BDPA Publication year: 2010
Tuning the photocatalytic activity of tin oxide through mechanical surface activation. Author(s): OLIVEIRA, C. R. de Tin oxide (SnO2) nanoparticles were synthesized by the co-precipitation method and mechanically modified by high-energy ball milling. The experimental results demonstrate that the collision with zirco... ... Repository: BDPA Publication year: 2022
Polyester composites reinforced with corona-treated fibers from pine, eucalyptus and sugarcane bagasse. Author(s): MARCONCINI, J. M. Repository: BDPA Publication year: 2017
Production of activated carbon from fast-pyrolysis biochar. Author(s): MAGALHAES, W. L. E. Thermochemical conversion of lignocellulosic biomass via fast-pyrolysis technique has become an interesting alternative to produce valuable bio-based products, such as the bio-oil. This alternative, f... ... Repository: BDPA Publication year: 2017
Chemical composition and antibacterial activity of the essential oil of Hyptis leucocephala. Author(s): SANTOS, S. N.; CASTANHA, R. F.; SILVA, L. J.; MARQUES, M. O. M.; SCRAMIN, S.; MELO, I. S. de Abstract: The paper reports chemical composition and antimicrobial activity of the essential oil of Hyptis leucocephala Mart ex Benth, Lamiaceae, isolated by hydrodistillation from leaves of plants co... ...

Momordica charantia L. variety from Northeastern Brazil: analysis of antimicrobial activity and phytochemical components. Author(s): CANUTO, K. M.; RIBEIRO, P. R. V. Repository: BDPA Publication year: 2019
Changes in hyphal morphology due to chitosan treatment in some fungal species. Author(s): OLIVEIRA JUNIOR, E. N.; MELO, I. S. de; FRANCO, T. T. In this work, changes in the hyphal morphology due to chitosan treatment in some fungal species were studied. Scanning electron microscope (SEM) observations revealed that chitosans with molar fractio... ... Repository: BDPA Publication year: 2012
Antitumoral, antioxidant and antimicrobial molecules from combretum rupicola. Author(s): SANTOS, S. N.; KAVAMURA, V.; CASTANHA, R. F.; ANDREOTE, F. D.; CARVALHO, J. E.; QUEIROZ, S. C. do N. de; MELO, I. S. de This investigation describes the anticancer, antioxidant and antimicrobial properties of the extracts of Combretum rupicola, a native plant from Northeast of Brazil. Methanolic, ethyl acetate and chlo... ... Repository: BDPA Publication year: 2013
Antifungal activity of bacterial strains from the rhizosphere of Stachytarpheta crassifolia. Author(s): SANTOS, S. N.; OLIVEIRA, L. K. X.; MELO, I. S. de; VELOSO, E. da S.; ROQUE, M. R. de A. This study evaluated the antifungal action of biomolecules produced from the secondary metabolism of bacterial strains found in the rhizosphere of semi arid plants against human pathogenic Candida alb... ...
