nano-srtio3 and tio2 powders were synthesized using sol-gel method. the srtio3 and tio2 powders were characterized using xrd, sem, and spectrophotometry. xrd analysis indicated that the tio2 powder was uniform anatase crystals of 9.9 nm and the srtio3 powders was cubic nano-crystal of 16.2nm. photocatalytic experiments revealed that methyl orange in water can be decomposed on the two powders un...

design and synthesis of high-performance hydrogenstorage materials. Although the weakest X-ray scattering amplitude of hydrogen made it difficult to determine their structure, we have succeeded in the first direct observation of elusive H2 molecules adsorbed in the nano-channels of a metal-organic porous material by the in situ synchrotron powder diffraction experiment of gas adsorption and by ...

PURPOSE Rapid development of nanotechnology has recently brought significant attention to the extraordinary biological features of nanomaterials. The objective of the present investigation was to evaluate morphological characteristics of the assembles of gold and platinum nanoparticles (nano-Au and nano-Pt respectively), with Salmonella Enteritidis (Gram-negative) and Listeria monocytogenes (Gr...

Bio-nano-process (BNP) has been proposed as promising bottom-up process to fabricate nanostructure. The application of BNP to memory devices such as resistive random access memory (ReRAM) is large interested because BNP could offer attractive solution to reduce the memory size and improve the device performance. We investigate the application of metal nano dot to ReRAM for control the filament ...

Two nano-sized mixed-ligand Cd (II) coordination polymers; [Cd (4,4' -bpy) (C4H4O4)].1/4 H2O (1) and[Cd(bpy)1.5 (NO3)2].3H2O (2) (bpy=bipiridine) were synthesized by a sonochemical method and characterized by elemental analyses, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The cry...

We present an overview of recent results obtained in nano-dispersed nonlinear neat organic liquids and liquid crystals. Experimental observations confirm the enhancement of nonlinear absorption in gold nano-spheres doped neat nonlinear liquids and extension of the bandwidth of efficient all-optical switching operation for visible-near infrared lasers in time scales ranging from sub-picoseconds ...

Stable gold nanoparticles stabilized by different mono and bi-functional arenethiols, namely, benzylthiol and 1,4-benzenedimethanethiol, have been prepared by using a modified Brust's two-phase synthesis. The size, shape, and crystalline structure of the gold nanoparticles have been determined by high-resolution electron microscopy and full-pattern X-ray powder diffraction analyses. Nanocrystal...
