Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...

Both the performance and regenerability of SO2 adsorbents made CuO supported on SBA-15 ordered mesoporous silica were studied for a cyclic DeSOx process under wet dry conditions. H2O vapor decreases 16 wt% loading CuO/SBA-15 (16CuO/SBA-15) adsorbent along adsorption/regeneration cycles performed at 400 °C. Indeed, breakthrough adsorption capacity this after ten adsorption- regeneration conditio...

The effect of aluminium content (x = 5, 20 and 40 wt %) in SBA-15 type silica supports used to obtain Pd/xAl-SBA-15 catalysts was evaluated the HDO reaction m-cresol at 300 °C, under atmospheric high (30 bar) pressure. Aluminium incorporation performed using two-step pH-adjustment method, affording deposition Al phases over previously precipitated. Pd thereafter deposed incipient wetness impreg...

Hexagonally ordered mesoporous silica materials MCM-41 and SBA-15 have been synthesized and loaded with Ag nanoparticles, utilizing both chemical synthesis and ultrashort pulsed laser ablation in liquid. In laser ablation, a silver target, immersed in aqueous suspension of ordered mesoporous silica SBA-15, was irradiated by ultra-short laser pulses to generate silver nanoparticles. For comparis...

An inorganic-organic hybrid fluorescence chemosensor (DA/SBA-15) was prepared by covalent immobilization of a dansylamide derivative into the channels of mesoporous silica material SBA-15 via (3-aminopropyl)triethoxysilane (APTES) groups. The primary hexagonally ordered mesoporous structure of SBA-15 was preserved after the grafting procedure. Fluorescence characterization shows that the obtain...

A new selective medium (CNA-P) that reduces or eliminates the inhibitory activity of bacteriocin-producing Streptococcus salivarius against beta-hemolytic streptococci has been developed and compared with sheep blood agar (SBA) for the sensitive detection of small numbers of beta-hemolytic streptococci in clinical specimens. CNA-P has as its basis a commercial medium (Difco Columbia CNA agar) s...

In UK medical schools, five-option single-best answer (SBA) questions are the most widely accepted format of summative knowledge assessment. However, writing SBA questions with four effective incorrect options is difficult and time consuming, and consequently, many SBAs contain a high frequency of implausible distractors. Previous research has suggested that fewer than five-options could hence ...
