Reactivity of tungsten-aryloxides with hydrosilane cocatalysts in olefin metathesis
(Soc Brasileira Quimica, 2002-01-01)
The reactivity of the [WCl4(OAr)(2)] (OAr = O-2,6-C3H3Cl2, O-2,6-C6H3F2 and O-C6H3Me2) systems, plus the silicon compounds Ph2SiH2 and polymethylhydrosiloxane (PMHS), were studied in metathesis reactions. The olefins used ...
All sol-gel electrochromic smart windows: CeO2-TiO 2/Ormolyte/WO3
(Taylor & Francis Ltd, 2002-12-01)
A solid state system having the configuration WO 3/Ormolyte/CeO2-TiO2 has been assembled. Syntheses routes for tungsten oxide WO3, and cerium-titanium CeO 2-TiO2 oxide sols, were developed. A novel solid electrolyte - ...

Optical limiting behavior of tungstate fluorophosphate glasses
(2003-12-01)
Nonlinear absorption measurements were performed on fluorophosphate glasses with high concentration of tungsten oxide. Large two-photon absorption coefficients, α2, were determined at 660 nm using nanosecond laser pulses. ...

A comparative study of hydrosilane compounds as cocatalysts in the metathesis of 1-hexene
(Elsevier B.V., 1998-12-21)
The selectivity of I-hexene metathesis using WCI6 as catalyst was evaluated with a series of hydrosilane-compounds as cocatalysts: Ph3SiH, Ph2SiH2, PhSiH3 and polymethylhydrosiloxane (PMHS). The metathesis reaction is ...
