The obtained samples were characterized by small angle X-ray scattering (SAXS), N2 adsorption/desorption, scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) and ultraviolet (UV) spectroscopy.The effect of magnetization on the drug release behavior of SBA-15 has been studied. Ibuprofen was chosen as a model drug. Drug release studies in simulated body fluid (SBF) at pH 7.4 showed that after 48 hours, the percentage of drug release through SBA-15 and magnetic SBA-15 could reach up to 80% and 20%, respectively. The obtained results reveal that the magnetization leads towards significant decrease of the drug release rate

The characterization of materials using XRD, TEM, N2 adsorption-desorption, and FT-IR techniques confirmed the successful attachment of organic moieties and preserving original structure of SBA-15 after modification step. Fluorescence experiments demonstrated that SBA-NCO was a highly selective optical sensor for the detection of Fe(3+) directly in water over a wide range of metal cations including Na(+), Mg(2+), Al(3+), K(+), Ca(2+), Cr(3+), Mn(2+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+), and Pb(2+) in a wide pH values.

Single crystal x-ray analysis conclusively confirmed the structure of the 2-amino-3-cyano-7,7-dimethyl-4-(4-methylphenyl)-5-oxo- 4H-5,6,7,8-tetrahydro-benzopyran.

Enzymatic esterification of meso-2,6-dimethyl-1,7-heptanediol with isopropenyl acetate in the presence of Pseudomonas cepacia lipase in organic medium provided the chiral nonracemic monoester in high enantiomeric excess (ee = 95%). This chiral building block was used in the formal syntheses of vitamin E side chain and the insect pheromone tribolure.
