To improve the dispersion ability of CuO nanoparticles (NPs), their surface was modified by chiral diacids (DAs) containing amino acids. The surface modification process was achieved using ultrasonic irradiation. DA could be absorbed on the surface of CuO. The carboxyl groups of DA may interact with surface of CuO NPs and form covalent bond with it. Interactions between DAs and CuO NPs were investigated
An efficient and convenient protocol for the synthesis of optically active [1,2,4]triazolo[3,4-<i>b</i>][1,3,4]thiadiazole derivatives containing L-amino acid moieties
Abstract New triazolothiadiazoles bearing L-amino acid moieties were synthesized by reaction of 4-amino-5-phenoxy-4H-1,2,4-triazole-3-thiol with L-amino acids in the presence of phosphorus oxychloride.

Commercially available silicon dioxide (SiO2) nanoparticles (NP)s were modified by chiral diacid coupling agents by ultrasonic irradiation. The acid groups can interact with the hydroxyl groups on the surface of SiO2 NPs. The interaction between NPs and diacid was confirmed by several techniques such as Fourier transform infrared spectroscopy, thermogravimetry analysis, X-ray diffraction, field emission scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM). The FE-SEM of the modified SiO2 NPs showed that the obtained particles have spherical nanostructured morphology with particle size from 21-57nm. The TEM image showed homogenous dispersion of particles with little aggregation.
