Smear layer removal for collagen fiber exposure after citric acid conditionings
(2010-12-01)
Aim: The aim of the present study was to compare the removal of the smear layer and exposure of collagen fibers of the root surface following the application of five citric acid solution concentrations. Methods and Materials: ...
Effect of the association between citric acid and EDTA on root surface etching
(2013)
Objective: This study aims to compare the clot stabilization on root surfaces conditioned with citric acid and ethylenediaminetetraacetic acid (EDTA). Materials and methods: Scaled root samples (n = 100) were set in five ...
Influence of concentration, time and method of application of citric acid and sodium citrate in root conditioning.
(2012-05-01)
The aim of this study was to establish the parameters of concentration, time and mode of application of citric acid and sodium citrate in relation to root conditioning. A total of 495 samples were obtained and equally ...
2,4-Dichlorophenoxyacetic acid (2,4-D) degradation promoted by nanoparticulate zerovalent iron (nZVI) in aerobic suspensions
(2013-05-30)
Reactive species generated by Fe0 oxidation promoted by O2 (catalyzed or not by ligands) are able to degrade contaminant compounds like the herbicide 2,4-dichlorophenoxyacetic acid. The degradation of 2,4-D was influenced ...
Effect of L-malic and citric acids metabolism on the essential amino acid requirements for Oenococcus oeni growth
(Wiley Blackwell Publishing, Inc, 2002-08)
Aims: The purpose of this work was to study the effect of L-malic and/or citric acids on Oenococcus oeni m growth in deficient nutritional conditions, and their roles as possible biosynthetic precursors of the essential ...
Xylooligosaccharides production by optimized autohydrolysis, sulfuric and acetic acid hydrolysis for minimum sugar degradation production
(2021-11-01)
Xylooligosaccharides (XOS) acts as a prebiotic, a food component that is not digested but stimulates the growth of beneficial microorganisms present in the intestine, such as bifidobacteria and lactobacilli, improving the ...
