Aluminum-Pillaring of a Montmorillonitic Clay: Textural Properties as a Function of the Starting Mineral Particle Size

Article - 29 Mar 2006

Development of new clean technologies in accordance with increasingly demanding environmental legislation requires new catalysts, adsorbents or catalyst supports; in this sense, clays are promising...
Comparative Study of (nBuCp)2ZrCl2 Performance in Ethylene Polymerization: Homogeneous and Supported Catalysts

Article - 14 Mar 2006

This article demonstrates that it is possible to overcome the problem of low activity of grafted zirconocene catalysts by the previous chemical modification of the silica surface with SnCl4.
Colored Transparent Organic-Inorganic Hybrid Coatings

Article - 11 Jan 2006

This paper reports on a sol–gel method for the deposition of red, green and blue PMMA-SiO2 hybrid films on glass substrates. The colored hybrid films are composed of a homogeneous organic-inorganic...
Factors to Enhance Thermal Conductivity of ÃŸ-Si3N4 Ceramics (Review)

Article - 11 Jan 2006

Research on processing â“i3N4 ceramics and their thermal conductivity are reviewed. Thermal conductivities are greatly affected by processing parameters such as purity of raw powders, type and amount...
Structural and Chemical Composition of Si-Al Oxy-Nitride Coatings Produced by Reactive DC Magnetron Sputtering

Article - 7 Nov 2005

Three main evaporation parameterss were controlled to produce Si-Al-O-N coatings: oxygen flux, nitrogen flux and substrate bias potential. These alterations allowed a diverse range of coatings with...
Tape-Cast Silicon Nitride for High Temperature Application

Article - 18 Oct 2005
