Synthesis of Polystyrene Microspheres to be Used as Template in the Preparation of Hollow Spherical Materials: Study of the Operative Variables
(Elsevier, 2012-07)
Mono-disperse polystyrene (PS) spheres were synthesized. The styrene polymerization was carried out using 4,4´-azobis 4-cyanovaleric acid (ACVA) or potassium persulfate (KPS) as initiators in the presence of polyvinyl ...
Morphology and topography analysis of mesoporous titania templated by micrometric latex sphere arrays
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this work, mesoporous titania is prepared by templating latex sphere arrays with four different sphere diameters at the micrometric scale (phi > 1 mu m). The mesoporous titania homogeneously covers the latex spheres ...
Synthesis and characterization of aluminum or copper tungstophosphate and tungstosilicate immobilized in a polymeric blend
(Pergamon-Elsevier Science Ltd, 2008-03)
Aluminum or copper tungstophosphates and tungstosilicates were synthesized and immobilized in a polymeric blend formed by polyvinyl alcohol and polyethylene glycol using the freeze-thawing method. The salts retained the ...
Accuracy of irradiance and power of light-curing units measured with handheld or laboratory grade radiometers
(Universidade Federal de Minas GeraisBrasilFAO - DEPARTAMENTO DE ODONTOLOGIA RESTAURADORAUFMG, 2019-07-22)
Esse estudo mensurou e comparou a irradiância e a energia de quatro fotopolimerizadores comerciais (Elipar S10, Elipar DeepCure-S, Corded VALO e Bluephase Style) utilizando diferentes tipos de radiômetros. Os dispositivos ...
Cooperative Effects of Aniline with DMSO in RuII Complexes: Tuning the Reactivity for Ring-Opening Metathesis Polymerization
(2019-11-10)
The complex cis,fac-[RuCl2(DMSO–O)(DMSO–S)3] [1] reacted with aniline (NH2Ph) under reflux to produce the complex trans,cis,cis-[RuCl2(DMSO–S)2(NH2Ph)2] [2], whereas at room temperature the resulting complex was ...
