Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

Combustion synthesis of tin dioxide (SnO2) was studied using a new synthesis approach where the combustion environment was augmented to control the temperature and flow conditions using methane as a supplemental fuel. The experiments were carried out at atmospheric pressure using a multi-element diffusion flame burner with a gas-phase precursor for SnO2 and solid-phase precursor for metal addit...

Reactions of a bis(boryl) tin complex towards carbon dioxide proceed via insertion into the Sn–B bond(s), with subsequent B–O reductive elimination leading to net diboration CO2.

Tin oxide nanowires (NWs) exhibit interesting electronic properties, which can be harnessed for applications in nanoelectronic devices and sensors. Oriented single crystalline tin oxide NWs were grown at 45 degrees from a titanium dioxide substrate. Their elastic properties were investigated in a two-point geometry using an atomic force microscope (AFM) coupled with a scanning electron microsco...

Nanoparticles of tin oxide, doped with Ce and Y, were prepared using the polymeric precursor method. The structural variations of the tin oxide nanoparticles were characterized by means of nitrogen physisorption, carbon dioxide chemisorption, X-ray diffraction, and X-ray photoelectron spectroscopy. The synthesized samples, undoped and doped with the rare earths, were used to promote the ethanol...

Nanostructured and nanoporous metal oxide thin films are rarely accessible by standard synthetic approaches but highly desired for many applications, e.g. as electrodes, transparent conducting coatings, sensors or surface catalysts. Template based sol–gel chemistry combined with post-synthetic hydrothermal treatment allows now the synthesis of nanocrystalline mesostructured porous thin films of...

the present experimental study reports on enhancement of heat transfer by addition of nanoparticles to the working fluid of commercial swimming pool heat exchangers under laminar flow condition. three different concentrations of titanium dioxide nanoparticles were added to the water as working fluid of a typical forced convective heat exchanger used to transfer heat to public swimming pools. th...

In this work, the titanium nitride (TiN) thin films were prepared on Si-wafers by using DC reactive magnetron sputtering from a pure target. The influence of N2 flow rates, in range 1.0-4.0 sccm, as-deposited TiN film’s structure was characterized several techniques. (i) crystal structures studied GI-XRD. (ii) thicknesses, microstructures, and surface morphologies analyzed FE-SEM. (iii) element...
