13C NMR and EPR spectroscopic evaluation of oil shale mined soil recuperation. 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... ...

13C ss-NMR Singular value decomposition and fitting for sorghum proteins conformation elucidation. 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
Supressão das anomalias de fase e batimentos laterais em espectros de RMN 13C obtidos com a sequência de precessão livre no estado estacionário. Repository: BDPA Publication year: 2010
13C-NMR spectroscopy evaluation of different pyrolysis feedstock. Different feedstocks and different pyrolysis processes produce carbonized materials (biochar) with different properties. The properties of these materials are very important when considering their agr... ... Repository: BDPA Publication year: 2008
Pulse sequence induced variability combined with multivariate analysis as a potential tool for 13C solid-state NMR signals separation, quantification, and classification. 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... ...

Structural characteristics of soil humic acids in coffee-cultivation systems: 13C NMR and analytical pyrolysis. Structural characterization of soil organic matter is still poorly understood in Brazilian agroecosystems. We aimed to identify the qualitative changes of soil humic acids as influenced by agroforestr... ... Repository: BDPA Publication year: 2011
CPMAS 13C NMR characterization of leaves and litters from the reafforestated area of mustigarufi in Sicily (Italy). Reafforestation is generally based on the planting of exotic fast growing tree species suitable for adapting to even harsh environments. Once the introduced plants ameliorate soil conditions, they can... ... Repository: BDPA Publication year: 2010
Espectroscopia de correlação 2D heteroespectral (NMR de 13C x EPR) no estudo da matéria orgânica do solo. No estudo da matéria orgânica do solo (MOS), é de uso corrente o tratamento dessas amostras com soluções de HF para extrair silicatos e concentrar o material orgânico, melhorando assim a qualidade dos... ...

13C e a Dinâmica do carbono orgânico do solo em Pastagem cultivada no Pantanal Sul-mato-grossense. O regime cíclico de cheias do Pantanal ocasiona épocas críticas de disponibilidade de forragens nativas, base alimentar do rebanho bovino de corte, principal atividade econômica da região. Isso tem le... ... Repository: BDPA Publication year: 2007
