Pulse sequence induced variability combined with multivariate analysis as a potential tool for 13C solid-state NMR signals separation, quantification, and classification. Author(s): NOVOTNY, E. H. Multivariate Curve Resolution (MCR) is a multivariate analysis procedure commonly used to analyze spectroscopic data providing the number of components coexisting in a chemical system, the pure spectr... ... Repository: BDPA Publication year: 2023
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
Synthesis, Vibrational Spectroscopic and Thermal Properties of Oxocarbon Cross - Linked Chitosan. Author(s): BRANDAO, H. de M. In this work specimens of chitosan which have been cross-linked covalently and ionically with different oxocarbon and pseudo-oxocarbon anions have been synthesised and characterized using infrared and... ... Repository: BDPA Publication year: 2015
13C ss-NMR Singular value decomposition and fitting for sorghum proteins conformation elucidation. Author(s): RIBEIRO, T. S.; SCRAMIN, J. A.; RODRIGUES, J. A. S.; BERNARDES FILHO, R.; COLNAGO, L. A.; FORATO, L. A. Kafirins, water-insoluble proteins from Sweet Sorghum BR501 grains, have been an alternative to prepare edible coatings for food due to their hydrophobic character. In this work, the secondary structu... ... Repository: BDPA Publication year: 2022
13C NMR and EPR spectroscopic evaluation of oil shale mined soil recuperation. Author(s): NOVOTNY, E. H. In this work, native forest soil (NFS) organic matter (SOM) sample and SOM samples from a neighboring forest soil area of an oil shale mine which is being rehabilitated for thirty years (RFS) were ana... ... Repository: BDPA Publication year: 2013
The quality of soil organic matter, accessed by 13C Solid State NMR, is more important than its content concerning pesticide adsorption. Author(s): NOVOTNY, E. H.; TURETTA, A. P. D. The need for food will increase by 59-98% from 2005 to 2050, and its global growth production has been achieved mainly through the intensive use of inputs such as pesticides and chemical fertilizers.... ...

Insights into the composition of humin from an irish grassland soil. Author(s): NOVOTNY, E. H. Humin is defined as the fraction of the humic substances (HS) that is insoluble in aqueous solution at any pH value (1). Because of its insolubility it has been the least studied of all the humic frac... ... Repository: BDPA Publication year: 2008
Char and humin fractions in Amazonian dark earths. Author(s): NOVOTNY, E. H. The high and specific SOM contents of the Amazonian Dark Earths (ADE, Terra Preta de Índios), and their high contents of P and Ca provide high natural fertility to the soils. Char or black carbon (B C... ... Repository: BDPA Publication year: 2008
