Copper oxide nanoparticles have been synthesized using micro reactors made of bis (2-ethylhexyle) sulfosuccinate (AOT)/water/n-Hexane microemulsions. The controls of particles size was achieved by varying water to surfactant molar ratio (W0). At constant of surfactant concentration the increases in value of W0increased the population of micelles and resulted in lager particle size. Their sizes and appearance were characterized by TEM, SEM, Zetasizer, uv-visible methods. Scanning electron microscopy (SEM) showed the spherical morphology of as prepared CuO nanoparticles. The Transmission electron microscopy (TEM) showed 85 nm size of as prepared CuO particles.

The present study is mainly aimed at the synthesis of copper oxide nanoparticles of varied size by green synthetic approach. The structural and morphological behavior of as-synthesized CuO nanoparticles were investigated using ultraviolet-visible spectral studies (UV-Vis), Fourier transform-Infrared spectroscopy (FT-IR), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM). The reduction of copper ions using aqueous extract of S. indica leaves produces nanoparticles of varied size and morphology. The images from SEM investigation revealed that the particles are spherical in shape with average diameter of 40–70 nm. TEM and HRTEM images clearly indicate the crystallinity and spherical nature of as-synthesized CuO nanoparticles with interplanar distance between two neighboring lattice fringes of 0.315 nm.

The biosynthesis of copper oxide (GS-CuO) nanoparticles utilizing Magnolia champaca floral extract was studied, where the Magnolia champaca was used for the reduction of precurosor to elemental CuO nanopartciles which also provides stabilization. Physiochemical properties of GS-CuO nanoparticles were described utilizing analytical strategies like UV-Vis, XRD, FT-IR, SEM, TEM, Zeta potential and DLS analysis. The UV-Visible spectrum gave maximum absorbance in the scale of 250-350 nm. The biosynthesized GS-CuO was crystallite in nature and it was investigated by XRD and was verified with JCPDS NO: 89-589. FT-IR analysis spectrum at 3302 cm-1 is assigned for alcoholic hydroxide group, 1022 cm-1 correspondings to CH3 shaking vibration respectively. The morphology of biosynthesized nanoparticles was between 20 to 40 nm and spherical shape was investigated utilizing TEM. The antoxidant potentiality of GS-CuO was evaluated by DPPH, ABST test, that demonstrated inhibition values at 76.30% and 66.46% respectively. Toxicity quality examination was performed utilizing morphological investigation, incubating, and viability rate examination on zebrafish embryonic model. The toxicity quality assessment with zebrafish uncovered organ advancement with various viability and hatching speed at 48 and 72 hpf with LC50 of 500 ± 15 mg/L.

AbstractThe detonation of explosives typically creates 100's of kbar pressures and 1000's K temperatures. These pressures and temperatures last for only a fraction of a microsecond as the products expand. Nucleation and growth of crystalline materials can occur under these conditions. Recovery of these materials is difficult but can occur in some circumstances. This paper describes the detonation synthesis facility, recovery of nano-size diamond, and plans to synthesize other nano-size materials by modifying the chemical composition of explosive compounds. The characterization of nano-size diamonds by transmission electron microscopy and electron diffraction, X-ray diffraction and Raman spectroscopy will also be reported.

This paper continues our previous work on preparation of triangular silver nanoparticles. The method proceeds with reaction of silver nitrate with hydrazine hydrate in the presence of polyvinyl pyrrolidone in aqueous solution. Effects of the concentration of PVP on the morphologies of Ag NPs were systematically investigated. The obtained Ag NPs were characterized by transmission electron microscopy and UV-visible spectrophotometer. The results showed that, triangular Ag NPs with edge lengths in the range of 50-200 nm were obtained using PVP as protective agent with lower concentration. As the concentration of PVP increased, spherical Ag NPs with their sizes about 6.2 nm were prepared and triangular Ag NPs were not obtained. The formation mechanism of triangular Ag NPs has been studied. Ostwald ripening is the driving force on the conversion of spherical Ag NPs to triangular Ag NPs in the presence of PVP.
