Additions of high modulus nano particles to Aluminum alloys offer the potential to develop a lightweight composite with high mechanical properties. It is extremely difficult to disperse nano-sized ceramic particles uniformly in molten metal. In order to investigate the effect of nano-alumina on the microstructure and mechanical properties of composite, a new method was used in stir casting to a...
Aluminum Matrix composites (AMCs) are light weight, high-strength materials with potential application in areas such as automobile, aerospace, defence, engineering and other industries. AMCs are projected to significantly reduce the overall weight of the vehicles and aircraft while maintaining satisfactory structural strength. Reinforcement of micron or nano-sized range particles with aluminium...
Well uniform microspheres of phase pure Covellite were synthesized through a simple hydrothermal approach using poly vinyl pyrrolidone (PVP) as surfactant. The micro-spheres were constituted of numerous self-organized knitted nano-ribbons of ∼ 30 nm thickness. The effect of conc. PVP in the hydrothermal precursor solution on the product morphology was investigated. Based on the out-coming produ...
Nanomaterial-directed, photothermal ablation is a practical future approach for the treatment of early-stage bladder cancer. Using a new PEGylation technique with bi-functional nitrophenyl carbonate PEG (bi-NPC-PEG) that promotes uniform suspension of the nanomaterial in solution, we have shown that gold nanorods conjugated to an anti-EGFR antibody (nano-alphaEGFR) bind effectively to EGFR-expr...
Uniform and single-crystalline Mn(3)O(4) nano-octahedrons have been successfully synthesized by a simple ethylenediaminetetraacetic acid disodium salt (EDTA-2Na) assisted hydrothermal route. The octahedron structures exhibit a high geometric symmetry with smooth surfaces and the mean side length of square base of octahedrons is ∼160 nm. The structure is reckoned to provide superior functional p...
Nanoparticles of a one-dimensional coordination polymer [Pb(L)(μ2-I)]n (1), (Lˉ = 1H1,2,4-triazole-3-carboxylate), have been synthesized by a sonochemical process and characterized by field emission scanning electron microscopy (FESEM), X-ray powder diffraction (XRPD), FT-IR spectroscopy and elemental analyses. The thermal stability of compound 1 both its bulk and nano-size has been studied by ...
We theoretically demonstrate the interplay of uniform spin-orbit coupling and uniform Zeeman magnetic field on the topological properties of one-dimensional double well nano wire which is known as Su-Schrieffer-Heeger (SSH) model. The system in the absence of Zeeman magnetic field and presence of uniform spin-orbit coupling exhibits topologically trivial/non–trivial insulator depending on the h...
The main aim of this paper was to determine the amount of Al2O3 reinforcement that results into best combination of strength. Magnesium nano composites containing 3.5, 7.0 and 14 volume percentage of Al2O3 were synthesized through powder metallurgy route. Resistance of furnace sintering technique (heating rate: 49°C/min).Micro structural characterization revealed reasonably uniform distribution...
This paper reports a simple and novel process for preparing nano-granular Zn(x)Fe(3-x)O(4) ferrite films (0 </= x </= 0.99) on Ag-coated glass substrates in DMAB-Fe(NO(3))(3)-Zn(NO(3))(2) solutions. The deposition process may be applied in preparing other cations-doped spinel ferrite films. The Zn content x in the Zn(x)Fe(3-x)O(4) films depends linearly on the Zn(2+) ion concentration ranging f...
Water Adsorption on Aggregates of Spherical Aerosol Nano Particles. (August 2005) Chu Nie, B.S., Nanjing University Chair of Advisory Committee: Dr. William H. Marlow A three dimensional integral equation is developed in order to compute water adsorption onto aggregates of spherical aerosol nano particles. The integral equation is derived from molecular density functional theory, with a weighte...
