Carbon nano-tube (CNT) reinforced metal matrix nano-composites have attracted a great deal of attention in recent years due to the outstanding physical and mechanical properties of CNTs. However, utilizing CNT as reinforcement for alloy matrixes has not been studies systematically and is still a challenging issue. In the present study, Cu80Fe20/10CNT nanocomposite was synthesized by mechanical ...

Restorative dental materials must be produced with special characteristics because they are operating in a medium environment different humidity and temperature. These day-to-day factors play an important role the lifetime of such restorative materials. Resin composites have been by far most successful applications meeting several stringent design requirements that difficult to achieve homogene...

This paper presents the development of low cost Nano membrane fabrication system. The system is specially designed for anodic aluminum oxide membrane. This system is capable to perform the processes such as anodization and electro-polishing. The designed machine was successfully tested for ‘mild anodization’ (MA) for 48 hours and ‘hard anodization’ (HA) for 3 hours at constant 0C. The system is...

objective(s): nowadays, nanoparticles bio production, considering their performance in medicine and biological science, is increasing. green synthesis of metal nanoparticles using organisms has emerged as a nontoxic and ecofriendly method for synthesis of metal nanoparticles the objectives of this study were the production of silver nanoparticles using avena sativa l. extract and optimization o...

nano-structured lanthanum strontium cobalt ferrite, la0.6sr0.4co0.2fe0.8o3 (lscf), was successfully synthesized via co-precipitation method using metal nitrates as starting materials. effects of precipitating agent and calcination temperature on the phase composition and morphology of synthesized powders were systematically studied using x-ray diffraction (xrd) and field emission scanning elect...

Hard X-ray fluorescence microscopy and magnified phase contrast imaging are combined to obtain quantitative maps of the projected metal concentration in whole cells. The experiments were performed on freeze dried cells at the nano-imaging station ID22NI of the European Synchrotron Radiation Facility (ESRF). X-ray fluorescence analysis gives the areal mass of most major, minor and trace elements...

A highly active and stable nano structured Pt/Mg1-xNixO catalysts was developed by a simple co-precipitation method. The obtained Pt/Mg1-xNixO catalyst exhibited cubic structure nanocatalyst with a size of 50-80 nm and realized CH4 and CO2 conversions as high as 98% at 900°C with excellent stability in the dry reforming of methane. The characterization of catalyst was performed using various ki...

Fabrication and scaling of disordered hyperuniform materials remain hampered by the difficulties in controlling spontaneous phenomena leading to this novel kind exotic arrangement objects. Here, we demonstrate a hybrid top-down/bottom-up approach based on sol–gel dip-coating nanoimprint lithography for faithful reproduction metasurfaces metal oxides. Nano- microstructures made silica titania ca...
