Micro-arc oxidation as a tool to develop multifunctional calcium-rich surfaces for dental implant applications
Titanium (Ti) is commonly used in dental implant applications. Surface modification strategies are being followed in last years in order to build Ti oxide-based surfaces that can fulfill, simultaneously, the following ...
INCORPORATION OF OXYGEN IN CRYSTALLINE ZEOLITIC CHROMOSILICATES - OPTICAL-IDENTIFICATION OF CHROMIUM(VI) BY PHOTOACOUSTIC-SPECTROSCOPY
(Royal Soc ChemistryCambridgeInglaterra, 1991)
3-Hydroxykynurenine bound to eye lens proteins induces oxidative modifications in crystalline proteins through a type I photosensitizing mechanism
(Elsevier Inc., 2019)
Photosensitized reactions mediated by endogenous chromophores have been associated with the etiology of age-related cataract disease. Endogenous chromophores such as 3-hydroxykynurenine (3OHKN) can be found in both free ...
Polymer electrolytes based on ethylene oxide-epichlorohydrin copolymers
(Elsevier Science BvAmsterdamHolanda, 2000)
Synthesis of PtSn nanostructured catalysts supported over TiO2 and Ce-doped TiO2 particles for the electro-oxidation of ethanol
(Elsevier Science, 2016-09)
PtSn/TiO2 and PtSn/Ce-doped TiO2 catalysts were synthesized and evaluated for ethanol electro-oxidation in acid media. Titanium dioxide and Ce-doped TiO2 nanoparticles were prepared by hydrothermal method followed by ...
Síntese, caracterização e deposição sobre óxido de grafeno de nanopartículas de óxido de índio dopado com estanho (ITO)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Química, 2011-11-22)
In this study, in the first step, Indium tin oxide nanoparticles were synthesized via a non-aqueous route involving the solvothermal treatment of indium (III) acetylacetonate and tin (IV) chloride in polyethylene glycol ...
Synthesis and characterization of manganese oxides employed in VOCs abatement
(Elsevier Science, 2005-10-27)
Two MnO2 were prepared by different methods: (i) MnCO 3 decomposition; and (ii) oxidation of acid MnSO4 solution. The combined use of X-ray diffraction (XRD), DRIFTS, DRS-UV-vis and TGA techniques revealed: (i) the presence ...
Synthesis, characterization, and catalytic properties of a mesostructured lamellar xerogel tungsten oxide phase
(ELSEVIER SCIENCE BV, 2011)
Cetyltrimethylammonium bromide (CTAB) and n-hexadecylamine (HDA) have been used as template in the synthesis of a mesolamellar xerogel tungsten oxide phase (WO(3)/CTAB/HDA). The catalytic properties of the resulting material ...
SYNTHESIS, CHARACTERIZATION AND THERMAL ANALYSIS OF 1:1 AND 2:3 LANTHANIDE(III) CITRATES
The synthesis and characterization of lanthanide(III) citrates with stoichiometries 1:1 and 2:3; [LnL center dot xH(2)O] and [Ln(2)(LH)(3)center dot 2H(2)O], Ln=La, Ce, Pr, Nd, Sm and Eu are reported. L stands for (C6O7H5)(3-) ...
Photodegradation of poly(3-hydroxybutyrate)
(ELSEVIER SCI LTD, 2010)
The effect of ultraviolet radiation on the properties of poly(3-hydroxybutyrate) (PHB) was studied. The PHB investigated is produced from microbial fermentation using saccharose from sugarcane as the carbon source to the ...
