-
(Colloids and Surfaces B: Biointerfaces, 2017-08-24)To optimize the therapeutic applications of Congo red (CR), a potential inhibitor of protein aggregation, the kinetics and thermodynamics of the interactions between CR and a model protein need to be understood. We used ...
-
(Pest Management Science, 2017-03-06)Tropane alkaloids are known to play a role in plant defence. By blocking acetylcholine receptors, they exert insecticidal and deterrent effects against herbivore insects. Carbamates are an important class of chemical ...
-
(Environmental Earth Sciences, 2015-02-05)This study determined the mobility of sulfentrazone in soils used for reforestation (Haplic Planosol, Ultisol, Humic Cambisol, and Regolithic Neosol) in the south of Brazil. To form the soil columns, previously prepared ...
-
(European Journal of Medicinal Chemistry, 2017-09-22)Aiming to obtain new potent leishmanicidal and cytotoxic compounds from natural sources, the triterpene hederagenin was converted into several new 1,2,3-triazolyl derivatives tethered at C-23 and C-28. For this work ...
-
(Scientific Reports, 2018-03-06)According to an earlier Abrikosov model, a positive, nonsaturating, linear magnetoresistivity (LMR) is expected in clean, low-carrier-density metals when measured at very low temperatures and under very high magnetic fields. ...
-
(Elsevier Fluid Phase Equilibria, 2017-06-25)Aqueous two-phase systems (ATPS) have been investigated as alternative systems for liquid-liquid extraction. Many ATPS phase diagrams for poly(ethylene glycol) (PEG) have been reported, but little information is available ...
-
(Fluid Phase Equilibria, 2011-06-15)Phase diagrams of aqueous two-phase systems composed of PEO1500 + salt (di-potassium phosphate + potassium hydroxide or ammonium sulfate or zinc sulfate) + water were determined at (283.15, 298.15, and 313.15) K. All systems ...
-
(Food Chemistry, 2019-07-01)In this work, we propose a method that employed a smartphone to capture images obtained from a colorimetric spot test to determine ascorbic acid (AA) in Brazilian Amazon native and exotic fruits. The spot test reaction was ...
-
(Talanta, 2008-02-08)This paper describes a new gas-chrormatography with electron capture detection (GC-ECD) method for determination of some pyrethroids in milk samples. The extraction of the pyrethroids was carried out by liquid–liquid ...
-
(Revista Brasileira de Ciência do Solo, 2001-01)The main objective of this work was to characterize the magnetic minerals and to identify their pedogenic transformation on a steatite-forming soil of Minas Gerais, Brazil. The iron-rich spinel phase was characterized by ...
-
(Plant Molecular Biology Reporter, 2009-06)Cocoa butter is an important raw material for the chocolate, pharmaceutical, and cosmetic industries. The butter content and quality in cocoa beans are genetically controlled characteristics, and affect its commercial value ...
-
(Química Nova, 2016-02)Electrodegradation of atrazine in water was performed using homemade (PA and PB) and purchased (PC) boron-doped diamond anodes. The degradation was monitored off-line by analyzing total organic carbon and high performance ...
-
(Environmental Monitoring and Assessment, 2008-09-11)The Iron Quadrangle (IQ) region, located in the state of Minas Gerais, has been the most important gold producing area in Brazil since the end of seventeenth century. The use of mercury for gold amalgamation in small scale ...
-
(Water, Air, and Soil Pollution, 2002-10)In order to evaluate the metal contamination from kaolin industry discharges into rivers in the State of Minas Gerais, Brazil, samples of river water and fluvial sediment were collected up- and down-river from the industries ...
-
(Revista Árvore, 2006-09-03)Neste trabalho foi avaliado o teor de extrativos em madeiras de eucalipto, por meio de extrações com acetona, mistura de tolueno:etanol (2:1), clorofórmio e diclorometano. As maiores porcentagens de extrativos totais foram ...
-
(The Journal of Physical Chemistry B, 2010-09-23)The effect of different ionic cosolutes (NaCl, Na2SO4, Li2SO4, NaSCN, Na2[Fe(CN)5NO], and Na3[Co(NO)6]) on the interaction between sodium dodecyl sulfate (SDS) and poly(ethylene oxide) (PEO) was examined by small-angle ...
-
(Environmental Science and Pollution Research, 2014-09-23)A method has been optimized and validated for the determination of fomesafen in soils using solid–liquid extraction with low-temperature partitioning (SLE/LTP) and analysis by liquid chromatography with a high-efficiency ...
-
(Journal of Environmental Management, 2015-06-01)We studied the adsorption of paraquat onto polyurethane foam (PUF) when it was in a medium containing sodium dodecylsulfate (SDS). The adsorption efficiency was dependent on the concentration of SDS in solution, because ...
-
(RECIE, 2006-01)Extração com água quente é o procedimento mais frequentemente usado na etapa inicial da determinação do boro disponível em solos. Por outro lado é um procedimento difícil de padronizar, consome tempo e a rotina usada é ...
-
(Brazilian Journal of Microbiology, 2018-10)The multi-enzyme complex (crude extract) of white rot fungi Pleurotus ostreatus, Pleurotus eryngii, Trametes versicolor, Pycnosporus sanguineus and Phanerochaete chrysosporium were characterized, evaluated in the hydrolysis ...
