Autor: V.L.R. Salvador, Wilson A.P. Calvo, F.M. Kondo, Nelson Batista de Lima, José Roberto Martinelli, S.L. Somessari, C.L. Duarte, M.I. Sato
Publikováno v: Radiation Physics and Chemistry. 191:109815
A catalyst is a substance that changes the rate of a reaction. In the petroleum industry, the catalysts are commonly used for fluid catalytic cracking and hydrocracking carried out with catalyst, each of them applied in a specific stage. These cataly

Improved Adhesion of Butyl Mastic Using Electron Beam Irradiation
Autor: Wanderley da Costa, Leonardo Gondim de Andrade e Silva, Hélio Wiebeck, José Roberto Martinelli
Publikováno v: Journal of Adhesion Science and Technology. 26:1699-1704
Butyl mastic is used in a number of industrial areas and in particular in the production of adhesives. The performance of this material can be improved by using ionizing radiation. In this work we showed that the shear forces in butyl mastic were mod

INERTIZATION OF SMALL-SCALE CHEMICAL WASTES USING IRON PHOSPHATE GLASS
Autor: Dalva Lúcia Araújo de Faria, José Roberto Martinelli, João Paulo Gobbo
Publikováno v: Química Nova, Vol 37, Iss 6, Pp 1058-1062 (2014)
The viability of small-scale heavy-metal waste immobilization into iron phosphate glasses was investigated. Several waste forms containing different amounts of heavy-ion wastes were evaluated (5%, 10%, 15%, 20%, 26%, 33%, 40% and 50% by mass) and the

Upconversion luminescence and decay kinetics in a diode-pumped nanocrystalline Nd^3+:YVO_4 random laser
Autor: José Roberto Martinelli, Laércio Gomes, Renato Juliani Ribamar Vieira, Niklaus Ursus Wetter
Publikováno v: Optics Express. 20:12487
Random lasing in nanocrystalline Nd(3+):YVO(4) powder is demonstrated. A method that analyzes the decay kinetics after long-pulse excitation is used to determine the laser characteristics. This method permits to measure the fractional contribution of
