Synthesis and characterization of SBA-3, SBA-15, and SBA-1 nanostructured catalytic materials

Journal of Colloid and Interface Science, 2007
A highly ordered large pore mesoporous silica molecular sieve SBA-3, SBA-15, Al-SBA-15, and SBA-1, were developed and characterized by XRD, BET, FTIR, SEM, and NMR-MAS. The catalytic materials were synthesized using different raw materials and operation conditions. These materials contain a regular arrangement of uniform channels with diameters between

Investigation of the Morphology of the Mesoporous SBA-16 and SBA-15 Materials

The Journal of Physical Chemistry B, 2006
Mesoporous SBA-16 and SBA-15 were studied in order to control their possible morphologies. SBA-16 is synthesized using a silicon source (tetraethoxysilane, TEOS) and a ternary system consisting of surfactant F127 (EO106PO70EO106), water, and butanol. The same ternary system, with higher butanol concentration, is used to form SBA-15 material as well. An

VAFB-2002-02: Results of Presence/Absence Testing for Cultural Resources at SBA-912, SBA-1040, SBA-1131, SBA-1146, SBA-1889, SBA-2880, and SBA-2953 Vandenberg Air Force Base, Santa Barbara County, California

2002
This document is a report that presents the results of absence/presence testing for a pavement removal project along a 1.4 mile portion of Old Beach Road and at the Surf Electrical Substation on Vandenberg Air Force Base. A shovel test pit excavation program was designed to test areas along the edge of pavement in the buffer zones of seven ...
