In the present study, the effect of post-rolling annealing heat treatment on the formation of intermetallic compounds between Al-Cu strips, in the presence of nickel coating on the Cu strips, was investigated. In addition, the effect of post-rolling annealing and intermetallic compounds on the bond strength of Al-Cu strips was evaluated. In order to prepare samples, Cu strips were coated with n...
New triphenylene derivatives 3 and 5, synthesized using a Suzuki-Miyaura coupling protocol and by a click reaction respectively, serve as potent chemosensors for various electron deficient nitroaromatic explosives, such as picric acid, trinitrotoluene, dinitrotoluene and dinitrobenzene. Derivative 5 exhibits a more sensitive response towards the nitroaromatics compared to derivative 3 due to it...
The biofilm formation of the oral fungal pathogen Candida on denture acrylic strips coated with saliva, serum and, saliva-serum pellicle were examined in vitro using Candida albicans (four isolates), Candida glabrata (three isolates) and Candida tropicalis (three isolates). The degree of biofilm activity varied depending upon both the isolate and the pellicle. Significantly increased biofilm ac...
The burden of life on the earth is the source of biological contamination in water. Nanotechnology has promising contributions in control of microbial contaminations and medicinal plants further increase these properties. Presently, copper acetate and nickel oxide nanoparticles were synthesized using 1mM solution of each with Ziziphus mauritiana leaves extract as reducing agent. Nanoparticles w...
abstract the problems caused by the traditional system of criminal justice (which are based on remuneration and rehabilitation) such as, lack of attention to victim’s rights and position and society, underlie the emergence of restorative justice which had the victim-centered perspective, with respect to the role of the offender and participation of civil society. meanwhile, criminal mediation ...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Red scale defect is known to be mainly caused by net-like Fe2SiO4–FeO. In the present study, the morphology of Fe2SiO4–FeO in a Si-containing steel was investigated by simultaneous thermal analysis, high-temperature laser scanning confocal microscopy, scanning electron microscopy, and energy dispersive spectroscopy. Only liquid Fe2SiO4–FeO can form a net-like morphology. Liquid Fe2SiO4–FeO is c...
The effect of depositing FeO nanoparticles with a diameter of 10 nm onto the surface of MgB(2) thin films on the critical current density was studied in comparison with the case of uncoated MgB(2) thin films. We calculated the superconducting critical current densities (J(c)) from the magnetization hysteresis (M-H) curves for both sets of samples and found that the J(c) value of FeO-coated film...
The origin of the so-called '21' µm feature which is especially prominent in the spectra of some carbon-rich protoplanetary nebulae (PPNe) is the matter of a lively debate. A large number of potential band carriers have been presented and discarded within the past decade. The present paper gives an overview of the problems related to the hitherto proposed feature identifications, including the ...
Statement of problem. The effect of gold electroforming on gold alloy was not studied. Purpose. This in vitro study investigate the effect of gold electroforming on gold-silver-palladium alloy. Material and methods. Three pieces of gold strips had undergone the electroforming procedures on one side and then half of the side again electroformed. The set mode for this study was program 1 (200 μm)...
