Preparation Nanosized TPA-Silicalite-1 with Different Silica Sources and Promoters

Optimization of Nanocrystals NaX Zeolite Synthesis with Different Silica Sources

The effects of varying the silica source on synthesis of NaX zeolite crystals via conventional hydrothermal method have been investigated. Five different silica sources were selected while other parameters like Al source, reaction and aging time, SiO2/Al2O3 molar ratio and temperature were same. The prepared products were characterized by XRD technique. The results showed that different cry...

Serum-, TPA-, and Ras-induced expression from Ap-1/Ets-driven promoters requires Raf-1 kinase.

Raf-1 serine-threonine protein kinase has the hallmarks of a critical switch that connects growth factor receptor activation at the cell membrane with transcriptional events in the nucleus. We show by use of Raf-1 dominant-negative mutants that Raf-1 is required for serum-, TPA-, and Ras-induced expression from the oncogene-responsive element in the polyomavirus enhancer. The minimal region of ...

Synthesis and photocatalytic activity of nanosized modified mesocellulous silica foams (MCFs) with PW12 and vanadium oxide

A series of tungestophosphoric acid and vanadium oxide supported on Mesocellulous Silica Foams (MCFs) featuring a well-defined three-dimensional (3D) mesoporosity were studied with regard to their performance in the photocatalytic activity to degrade Oezine Y (OY). This nanosized mesoporous catalyst (PW12@V-MCF) was characterized by FTIR, XRD, BET and TEM. XRD shows that the structure of MCF re...
