A suite of plate-impact experiments have been conducted to determine the dominant factors in dynamic damage evolution in uniaxial strain tensile (spall) experiments. The first group of experiments addresses the effect of microstructure by using copper samples with varying grain sizes while maintaining similar loading…
Summary This study was carried out to investigate the effects of dietary powder of Puncture Vine (Tribulus terrestris (TT)), carried with cotton oil, cellulose and bentonite on growth performance, carcass characteristics, TBA (thiobarbituric acid) value of breast meat and blood parameters of broiler chicks. In total,…
Nickel oxide (NiO) thin films were successfully deposited on Corning 7059 glass substrates at different oxygen partial pressures in the range of 1 10 – 4 to 9 10 – 4 mbar using dc reactive magnetron sputtering technique. Structural properties of NiO films showed polycrystalline nature with cubic structure along (2…
Reaction of the potassium salt of N-thiophosphorylated thiourea 6-MeO(O)CC(6)H(4)NHC(S)NHP(S)(OiPr)(2) (HL) with PdX(2) (X = Cl(-), Br(-), I(-)) leads to the dark red binuclear complexes [(PdLX)(2)], while the same reaction with PdY(2) (Y = NO(3)(-), CN(-), CH(3)COO(-)) leads to the light red mononuclear complex [PdL(…
We present the preparation of nanometer-size organic crystals using femtosecond laser induced forward transfer (Fs-LIFT) method. 1,4-Bis(4-methylstyryl)benzene (BSB-Me) nanocrystals are directly deposited on the substrate to form a nanocrystal film. Size and morphology as functions of applied laser fluence are investi…
Article history: Received on: 07/09/2012 Revised on: 18/09/2012 Accepted on: 22/09/2012 Available online: 28/09/2012 A facile and reliable method to perform pilot pharmacokinetic (PK) and biodistribution studies is necessary for expediting the overall development and clinical translation of novel nanoparticle drug car…
Oxygen ion conducting ceramics (Sc2O3)0.1(ZrO2)0.9, (Sc2O3)0.1(CeO2)0.01(ZrO2)0.89 and Ce0.9Gd0.1O1.95 were sintered from powders with different specific surface areas. The produced ceramics were studied by scanning electron microscopy and impedance spectroscopy methods. Impedance spectroscopy measurements were perfor…
Nanotechnology is gaining tremendous impetus in the present century due to its capability of modulating metals into their nanosize. Metallic nanoparticles are traditionally synthesised by wet chemical techniques, where the chemicals used are quite often toxic and flammable. In this work, we describe a cost effective a…
Highly ordered cubic mesoporous carbons with the cubic I4132 mesostructure have been synthesized via organic–inorganic self-assembly of tetraethoxysilane (TEOS), triblock copolymer Pluronic P123, and sucrose under acidic conditions.
The preparation of electrically conductive silicon nitride (Si3N4) ceramics by dispersing carbon nanotubes (CNTs) has been studied in the recent years. However, the density and strength of Si3N4 ceramics was found to deteriorate and the CNTs disappeared after firing at high temperatures because CNTs prevent Si3N4 from…
The thermal decomposition pathways of the tungsten dimethylhydrazido complexes Cl 4 (RCN)W(NNMe 2 ) ( 1a : R=CH 3 ; 1b : R=Ph), precursors for single source deposition of WN x C y , were investigated using a combination of experiments and calculations. Raman scattering studies were performed in an impinging-jet, up-fl…
The aim of this paper is to study the importance of nuclear data uncertainties in the prediction of the uncertainties in keff for LWR (Light Water Reactor) unit-cells. The first part of this work is focused on the comparison of different sensitivity/uncertainty propagation methodologies based on TSUNAMI and MCNP codes…
The selection of a three phase synchronous generator most suitable to be used as a power supply for testing of single-phase and threephase power transformers is described in the paper. The emphasis is on the analysis of the armature winding connection and sizing of the damper winding due to unsymmetrical load of a gen…
The finite size effect of proton conductivity of amorphous aluminosilicate thin films, a-Al(n)Si(1-n)O(x) (n = 0.07, 0.1, 0.2, 0.3 and 0.45), prepared by a sol-gel process was investigated by experimental and numerical techniques. High-resolution TEM clarified that a-Al(n)Si(1-n)O(x) films had the heterogeneous nanosc…
Penetration of projectiles was measured for hemispherical and conical nose shapes penetrating granular media. Targets were beds of Ottawa sand and Eglin sand. Projectiles were rigid metals. Experimental parameters that were varied included velocity (from 300 to 600 m/s), nose shape, sand density, and scale (from 5 mm…
In this work, tribological behavior and material degradation mechanisms of Nitro-carburized AISI H11 hot work tool steel were investigated during sliding against cemented tungsten carbide (WC/Co). The diffusion layer with an iron-nitrocarbide (Fe (N,C)) compound layer was developed on pre-hardened tool steel by a low…
We previously reported that organic solvent (ethanol) treatment of a film formed by plasma enhanced chemical vapor deposition (PE-CVD) remarkably improved the gap-filling property of O 3 -tetraethylorthosilicate (O 3 -TEOS) atmospheric pressure chemical vapor deposition (AP-CVD) film. Based on these results, we conclu…
A non-aqueous titration method was developed to assay the insensitive high explosive 1,1-diamino-2, 2-dinitroethene (FOX-7). The weak acidic nature of FOX-7 (pKa 10.6) was exploited in the assay method. The sample was dissolved in the protophilic solvent N, N-dimethylformamide and titrated against sodium methoxide sol…
Many components in the shipbuilding industry are made of copper-based alloys. These pieces tend to break due to corrosion generated by a marine environment; such components can be salvaged through surface engineering, through deposition of suitable coatings. This paper studied the influence of three surface preparatio…
This article presents the analytical strain solution of the rate-form non-associative elastic-plastic constitutive model using the Drucker-Prager yield criterion with linear isotropic hardening. The strain solution is obtained using constant stress rate assumption. The solution for the deviatoric radial loading case i…
