Hydrogenation of Tetralin Over Ir Catalysts Supported on Titania-Modified SBA-16
(Springer, 2014-03)
A series of Ti modified SBA-16 supports and their respective Ir-catalysts were prepared and characterized to study the effect of support preparation method on the dispersion of iridium and on the characteristics of Ir ...
Síntesis y Caracterización de LiF:Mg,Ti para Dosimetría de Radiaciones Ionizantes
(2011-11-25)
The emission of light thermically stimulated, simply known as Thermoluminescence (TL), is the physical property that some crystalline solids have to emitting light after they have been irradiated, where the amount of emitted ...
A novel Ag doping Ti alloys route: Formation and antibacterial effect of the TiO2 nanotubes
(2021-03-01)
Titanium has been widely used for clinical purposes, but post-surgical infections remain a troublesome issue, impairing patient's quality of life. Silver (Ag) is a potent broad-spectrum antimicrobial agent whose disinfecting ...
Incorporation of TiO2 nanotubes in a polycrystalline zirconia: Synthesis of nanotubes, surface characterization, and bond strength
(Elsevier B.V., 2018-10-01)
Statement of problem. Despite numerous advantages such as high strength, the bond of yttria-stabillzed tetragonal zirconia polycrystal (Y-TZP) to tooth structure requires improvement. Purpose. The purpose of this in vitro ...
Ti-MCM-41 catalysts prepared by post-synthesis methods. Limonene epoxidation with H2O2
(Elsevier Science, 2008-04)
Ti-MCM-41 catalysts were prepared incorporating Ti by post-synthesis methods: wetness and wet impregnation of MCM-41 mesoporous solid. The samples were characterized by XRD at low angle, UV-vis DRS, Raman spectroscopy, ...
Antibacterial photocatalytic activity of different crystalline TiO2 phases in oral multispecies biofilm
(2018-07-01)
Objective: Titanium dioxide (TiO2) incorporation in biomaterials is a promising technology due to its photocatalytic and antibacterial activities. However, the antibacterial potential of different TiO2 crystalline structures ...
Fabricação de membranas fibrosas de compósito PVDF/TIO2 pelo método de fiação por sopro em solução

PVDF, PVDF/TiO 2 and PVDF/TiP membrane of were successfully prepared by solution blow spinning method. A study on the influence of concentration of PVDF in DMF, to obtain PVDF nanofibers without incorporation of nanoparticles ...
CO oxidation over Co-catalysts supported on silica-titania – The effects of the catalyst preparation method and the amount of incorporated Ti on the formation of more active Co3+ species
(2018-09-05)
Herein, a sol-gel one-pot methodology to tune the activity of Co-catalysts supported on silica-titania to CO oxidation is described. SEM, TEM, EDS, XPS and H2-TPR evidenced a higher Co dispersion from that method when ...
Avaliação da remoção de hidrocarbonetos aromáticos (BTEX) em águas utilizando materiais nanoestruturados do tipo Ti-MCM-41
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2012-01-30)
Volatile Organic Compounds are pollutants coming mainly from activities that use fossil fuels. Within this class are the BTEX (benzene, toluene, ethylbenzene and xylenes) compounds that are considered hazardous. Among the ...
