Formylglycine-generating enzymes can selectively recognize and oxidize cysteine residues within the sulfatase sub motif at the terminus of proteins to form aldehyde-bearing formylglycine (FGly) residues, and are normally used in protein labeling. In this study, an aldehyde tag was introduced to proteins using formylglycine-generating enzymes encoded by a reconstructed set of the pET28a plasmid ...

The growth of ordered nanorods of mesoporous SBA-15 inside a porous alumina membrane has been achieved for the first time by a simple sol-gel method. The obtained SBA-15 nanorods themselves have ordered hexagonal mesochannels with a size of about 6 nm and have been arranged to form hexagonal arrays by the limitation of pores of the alumina membrane. The synthesized alumina membrane with mesopor...

Trinitroglycerin (TNG) is an industrial chemical mostly known for its clinical use in treating angina and manufacturing dynamite. The wide manufacture and application of TNG has led to contamination of vast areas of soil and water. The present study describes degradation of TNG with zero-valent iron nanoparticles (ZVINs) in water either present alone or stabilized on nanostructured silica SBA-1...

Antibacterial tests of Ag/SBA-15 from petung bamboo leaf ash against Escherichia coli were carried out. Modification SBA-15 with Ag was conducted using the wet impregnation method while antibacterial test out by well diffusion and disc various concentrations Ag/SBA-15. The has a surface area ​​143 m2/g, pore diameter 8.4 nm volume 0.35 cm3/g. SAXS pattern /SBA-15 showed 3 typical peaks in 0o -2...

The partial oxidation of methanol to formaldehyde was studied over highly dispersed vanadia supported on mesoporous silica SBA-15 (VOx/SBA-15). VOx/SBA-15 catalysts were prepared by a novel grafting/ion-exchange method and characterized using UV-VISand Raman spectroscopy. The resulting surface vanadium oxide species (0 – 2.3 V/nm), grafted on the inner pores of the SBA-15 silica matrix, consist...

We report the first synthesis of titanium nitride (TiN) nanoparticles inside the nanoscale channels of mesoporous silica SBA-15. The TiN precursor, Ti(NMe(2))(4) in toluene, was incorporated into the methyl group-modified channels of the SBA-15 powder. The functionalization of pore surfaces with methyl groups generates hydrophobic surfaces that facilitate impregnation with Ti(NMe(2))(4) and min...

NiII and MnIII Schiff base complexes (Salophen-Ni Salophen-MnCl) bearing a pending carboxylic group were prepared characterized. Both grafted onto mesoporous amino-functionalized SBA-15 silica, by formation of an amide function between the propylamine groups support acid functions salophen ligand (corresponding respective to 1.30 wt.% Ni 1.06 Mn). The co-catalytic behaviour free was then evalua...
