  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

  为了提高CuO纳米颗粒（NPs）的分散能力，其表面被含有氨基酸的手性二酸（DAs）改性。使用超声波辐照实现了表面改性过程。DA可以被吸收在CuO的表面上。DA的羧基可与CuO NP的表面相互作用并与其形成共价键。通过不同的技术研究了DA与CuO NP之间的相互作用。X射线衍射图证明，改性过程不会改变CuO的晶相。结果证实了有机官能团在NP表面上的成功沉积。

  In this study, a simple, fast and environmentally friendly protocol has been proposed for the synthesis of layered double hydroxides (LDHs) and organomodified chiral LDHs under ultrasound irradiation as a green and fast tool for the first time. Novel chiral LDHs were synthesized in one step from the co-precipitation reaction of the Al(NO3)3·9H2O, Mg(NO3)2·6H2O and different bioactive N-trimellitylimido-l-amino

  In this study, new chiral poly(amide-imide)s (PAIs) were synthesized from polycondensation reaction of 3,5-diamino-N-(thiazole-2-yl)benzamide with various N-trimellitylimido-L-amino acids in a green medium consisting of molten tetra-n-butylammonium bromide and triphenyl phosphite. The polymerization reactions produced new PAIs with high yields and inherent viscosities ranging from 0.28 to 0.38 dL/g. The obtained materials were characterized by means of Fourier transform infrared, H-1 NMR spectroscopy, specific rotation measurements, thermogravimetric analysis, X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and elemental analysis techniques. The FE-SEM micrographs and XRD results showed that the polymers have nanostructure morphology and they are amorphous in nature.

  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.
