Tranparent and colourless single crystals of phosph orous acid admixtured L-alanine (PALA) were grown by solution method for the first time at room temperature. In this work, L-alanine and phosphoro us acid were used to synthesize PALA salt. XRD analysis confirms orthorhombic structure of the grown crystal. Suitabilit…
Thermal decomposition studies of metal ethylxanthates of Ca(II), Mn(II), Fe(III), Co(II) and Ni(II), were carried out in dynamic air and dynamic nitrogen atmospheres using simultaneous TG-DTA techniques with a view to compare their thermal behavior. Thermal stabilities of these five metal ethylxanthates in the two atm…
Water-soluble cupric oxide nanoparticles are stable over a wide range of pH and temperature. This excellent stability in the form of aqueous colloidal suspensions makes the application of the water-soluble CuO nanoparticles easier in aqueous systems. In the present study, copper oxide nanoparticles are synthesized usi…
The intention of the present short review is to introduce to the non-specialist reader the feasibility of the use of alternative materials not generally considered by engineers working in mechanical and structural applications. That is, the use of specialised aerospace rivets in the more general area of construction i…
In this study, a 0.09 wt% of active carbon catalyst was added onto anode and cathode channels made of PDMS (Polydimethylsiloxane) in order to promote the fuel decomposing reaction in the fuel channels, and further enhance the output of single DMFCs (Direct Methanol Fuel Cell) and twin stack DMFCs under various operati…
Chemical route for the synthesis of polymer composites with oxide materials enhances the composite technology. Polyaniline (PANI) and Polyaniline-magnesium stanate (PANI-MgSnO 3) composite material was prepared by insitu polymerization of aniline with Magnesium stanate (MgSnO 3) as composite material. Variation in the…
The purpose of this research is to study the properties of gallium based restorative alloy in vitro and compare with that of high copper denta l amalgam . X - ray diffraction analysis and microstructure observation has been performed on gallium restorative alloy to determine and observe the existing phases . The speci…
Magnesium aluminate spinel (MgAl2O4) with high transparency has been wildly used in various applications because of its high mechanical strength and good optical properties. The aim of this work is to evaluate the effects of an additive, Li5AlO4, on the sinterability of MgAl2O4. The concentrations of Li5AlO4 focused i…
• 45% of surveyed hunters desired an increase in the current population while 39% desired no change. • Within the landowner survey, the greatest proportion of respondents in all strata, except large landowners in the south, reported that the deer population on their property and surrounding area was about right. The g…
Noise (unwanted sound) is a kind of pollution that hits public community in many cities and industrial areas, harms human health both physically and psychologically. The aim of the study is producing an acoustical composite as building material component for absorbing noise. The method was conducted by synthesizing an…
Norfloxacin Eu(III) complex was synthesized with chemical formula [Eu(NFX)3].6H2O. The NFX acts as deprotonated bidentate ligand through the oxygen atom of carbonyl group and the oxygen atom of carboxylic group. Elemental analysis, FT–IR spectral, electrical conductivity, thermal analysis (TG/DTA) studies have been us…
Reactivity of C60 was investigated by DFT/PBE/SBK with respect to acetylene intercalated into fullerite Formation of new chemical compounds between C60 and C2H2 in the octahedral pore fullerite was predicted. Spectral properties (IR-spectrum and the NMR chemical shifts) of the compounds were calculated.
Reinforced electrospun PAN nanofibers with mixture of carbon nanotubes and carbon nanofibers were produced via electrospinning techniques. The study was conducted to examine the effect of ratio CNT:CNF to the conductivity and thermal stability of the electrospun PAN nanofiber. The electro-spinning was performed using…
Recent advances in the application of nanotechnology in medicine, often referred to as nanomedicine, may revolutionize our approach to healthcare. Cancer nanotechnology is a relatively novel interdisciplinary area of comprehensive research that combines the basic sciences, like biology and chemistry, with engineering…
2 Abstract: Corrosion due to pitting and heat affected zone (HAZ) in weldments are the serious problems for any welding industry, which reduces the service life of the product. It is a challenging task for a metallurgist to solve the above problem. Super-duplex stainless steels present excellent combination of mechani…
We present a novel framework to solve thin-film equations with an explicit non-zero contact angle, where the support of the solution is treated as an unknown. The algorithm uses a finite element method based on a gradient formulation of the thin-film equations coupled to an arbitrary Lagrangian-Eulerian method for the…
