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
Soil surface-active fauna in degraded and restored lands of Northeast Brazil. Author(s): LEITE, L. F. C. Land degradation reducing vegetation cover may affect the soil surface-active fauna because both aboveground and belowground invertebrates depend on complex plant communities. In this study, we evalua... ... Repository: BDPA Publication year: 2015
Using a Surface-Response Approach to Optimize the Photocatalytic Activity of rGO/g-C3N4 for Bisphenol A Degradation. Author(s): RIBEIRO, C. Although environmental and clean energy research has identified graphitic carbon nitride impregnated with reduced graphene oxide (rGO/g-C3N4 ) as a potential, efficient non-metallic photocatalyst, its... ...

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
Modeling of the shrinkage kinetics of coffee berries during drying. Author(s): AFONSO JUNIOR, P. C.; CAMPOS, S. C. The effects of drying conditions on the shrinkage of Coffea arabica L., cultivar Catuaí Vermelho, were studied. An exponential model derived from the kinetic model was used to describe the shrinkage k... ... Repository: BDPA Publication year: 2011
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
Controlled biocide release from hierarchically-structured biogenic silica: surface chemistry to tune release rate and responsiveness. Author(s): MATTOS, B. D.; TARDY, B. L.; PEZHMAN, M.; KÄMÄRÄINEN, T.; LINDER, M.; SCHREINER, W. H.; MAGALHAES, W. L. E.; ROJAS, O. J. Biocides are essential for crop protection, packaging and several other biosystem applications. Therein, properties such as tailored and controlled release are paramount in the development of sustaina... ... Repository: BDPA Publication year: 2018
Polyester composites reinforced with corona-treated fibers from pine, eucalyptus and sugarcane bagasse. Author(s): MESQUITA, R. G. A.; CÉSAR, A. A. S.; MENDES, R. F.; MENDES, L. M.; MARCONCINI, J. M.; GLENN, G.; TONOLI, G. H. D. Repository: BDPA Publication year: 2017
Equipments to manage soil and irrigated rice straw for the sequential sowing of soybean in tropical floodplains. Author(s): SILVA, J. G. da; NASCENTE, A. S.; SILVEIRA, P. M. da The presence of straw hinders the sowing of soybean cultivated in succession to rice, in areas irrigated by flooding. This study aimed to evaluate the combination of different configurations of a rice... ... Repository: BDPA Publication year: 2019
Antimicrobial and Photoantimicrobial Activities of Chitosan/CNPPV Nanocomposites. Author(s): FACCHINATTO, W. M.; ARAUJO, L. O.; MORAES, T. B.; ABELHA, T. F.; LIMA, T. H. N.; SANTOS, D. M. dos; CAMPANA-FILHO, S. P.; COLNAGO, L. A.; CAIRES, A. R. L. Multidrug-resistant bacteria represent a global health and economic burden that urgently calls for new technologies to combat bacterial antimicrobial resistance. Here, we developed novel nanocomposite... ... Repository: BDPA Publication year: 2022
