Chelating agent effects in the synthesis of supported Ni nanoparticles as catalysts for hydrogen production
(Elsevier Science, 2021-07)
A series of Ni supported over MgAl2O4–CeO2 catalysts have been prepared by the wet impregnation method as catalysts for steam ethanol reforming. The synthesis was performed using nitrilotriacetic acid (NTA) or citric acid ...
Efeito do cádmio sobre a enzima d-aminolevulinato desidratase de pulmão de ratos in vitro: interação com agentes quelantes e antioxidantes
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2007-06-01)
The exposure of human populations to a variety of heavy metals has been a public health concern. Cadmium is a non-essential elements due to its immense usage in various industrial applications, is an environmental contaminant ...
Hydrogen production from ethanol: Synthesis of Ni catalysts assisted by chelating agents
(Elsevier, 2020-02)
The steam reforming of ethanol was studied over supported Ni catalysts. The catalysts were prepared by the wet impregnation method, using chelating solutions (ethylendiaminetetraacetic acid, EDTA; nitrilotriacetic acid, ...
Novel Coumarin-Quinoline Hybrids: Design of Multitarget Compounds for Alzheimer's Disease
(Wiley-Blackwell, 2019)
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 ...
Blood cell attachment to root surfaces treated with EDTA gel.
(2005-04-01)
Root debridement generates a smear layer which contains microorganisms and toxins that could interfere in periodontal healing. For this reason, different substances have been used to remove it and to expose collagen fibers ...
A new application of humic substances: Activation of supports for invertase immobilization
(2000-12-01)
Invertase was immobilized on aminopropyl silica (APTS-SiO2) activated with humic substances (APTS-SiO2-HS) and on aminopropyl silica activated with glutaraldehyde (APTS-SiO2-GA). The resulting activity of both systems was ...
