This paper focused on the performance characteristics of the highest grade of the Russian natural gas pipeline-K65 grade,combined with the Second West-East Gas Pipeline standard and API SPEC 5L standard,it made an in-depth discussion for the characteristics of Russia pipeline standards.There are bigger differences bet…
Raman spectra of amorphous carbon nitride films (a-C:N) resemble those of typical amorphous carbon (a-C), and no specific features in the spectra are shown due to N doping. The present work provides a correlation between the microstructure and vibrational properties of a-C:N films from first principles. The six period…
The bacteriophage P22 protein cage can be bioengineered to contain a high-relaxivity gadolinium (Gd) payload internally and targeting ligands externally. It also enables phage-library-based identification of novel targets. Thus, P22 may have advantages for molecular/cellular imaging by MRI. 1) P22: The P22 protein cag…
In this study, polyethylene-terephthalate (PET) nonwovens are treated using an atmospheric plasma and the effects of the treatment time, treatment power and discharge distance on the ability of water-penetration into the nonwovens are investigated. The result indicates that the method can improve the wettability of PE…
The structure and phase composition of prehardened 38CrNi3MoVN steel subjected to an electron beam treatment have been studied by the metallographic, scanning, and transmission electron microscopy. The e-beam parameters are as follows: the energy of accelerated electrons U ~ 15 keV, the beam current I ~ 60 ?, the curr…
In this paper we propose a new approach for CdTe activation treatment. Starting from a baseline of CdTe devices made with CdCl2 activation process we present a double treatment where CdCl2 and Freon®, namely difluorochloromethane, treatments are applied in sequence. This new activation process delivered solar cells wi…
A nonpolar SiC(11 0) substrate has been used to fabricate epitaxial graphene (EG). Two EGs with layer numbers of 8–10 (referred to as MLG) and 2–3 (referred to as FLG) were used as representative to study the substrate effect on EG through temperature-dependent Raman scattering. It is found that Raman lineshifts of G…
The effect of curcum plant extract on the corrosion of steel used in sanitation treatment plants in 3.5% NaCl and 16 ppm Na2S was investigated by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) techniques. The results obtained showed that the cu…
The interlayer transport of an electron in bilayer graphene influenced by a phonon in the presence of a biased potential is investigated using the tight-binding approach. The in-plane optical mode E2g and out-of-plane optical mode B1g associated with the applied biased potential are considered to compute and discuss t…
Polycrystalline BiFeO3 thin films that exhibit a photo-induced current under the irradiation of visible light have been synthesized on Pt/TiO x /SiO2/Si substrates by chemical solution deposition. The quick on/off response of the photocurrent to light in these BiFeO3 thin films is demonstrated. It is also shown that t…
This paper presents the performance analysis of rotary cottonseed dryer. Experiments were performed on cottonseeds, at inlet air temperatures of 100, 110, 120oC, and drying air mass flow rates of 0.00563, 0.0064, 0.00709 kg/s by using two different flights. The performance of dryer was evaluated by checking effect of…
The main objective of this review is to describe some of the important topics related to the use of marine and protective coatings for anti-corrosive purposes. In this context, ” protective” refers to coatings for containers, off shore construction, pipe lines, pumps, steel structures, chemical equipment, bridged, sto…
Effect of pouring temperature on microstructural evolution, mechanical and electrical properties of cast AA6063 Aluminum alloy has been studied. Samples were cast at pouring temperatures between 700-780 o C at 20 o C interval and were subjected to microstuructural examination, electrical conductivity, hardness and str…
For the treatment of many diseases large molecular weight protiens are required. These can be availabl e with the availability of Hydrogels. Hydrogels are hydrophili c, three-dimensional networks, which are able to im bibe large amounts of water or biological fluids, and th us resemble, to a large extent, a biological…
TiO2 nanostructures with flower like morphology was synthesized by a simple microwave assisted acid hydrolysis of TiCl3. Tuning the morphology was achieved by the microwave treatment and the nature of the medium or the precipitating agent. As-synthesized titania nanoflowers, was characterized by X-ray diffraction (XRD…
In this study tensile-mechanical properties of graphene containing polyamide 6 nanocomposites were deeply analysed via cyclic measurements. Injection moulded specimens with different nanofiller contents (0…1 wt%) were used for the investigations. At the cyclic tests the loading force was increased with 100 N increment…
Cadmium Sulphide (CdS) thin films are deposited on glass substrate by relatively simple, quick and cost effective successive ionic layer adsorption and reaction (SILAR) method at room temperature (27 0 C). For fine nanocrystalline thin film growth the parameters including concentrations of cationic and ionic precursor…
Abstract: A highly promising approach to the improvement of the properties of bituminous compositions for road building (BCRB) is introduction of surfactants that increase the strength of the adhesive bond between bitumen and the rock material surface and provide required rheological properties of BCRB as a result of…
In the present work, nano scaled zero valent irons (nZVI) were synthesized from the plant extract of under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state. A systematic characterization of nZVI was performed using UV, XRD and SEM studies. The diameter of iron nanoparti…
Fibroblasts are the major cell types found in the granulation of wound tissue and play a key role in wound healing. In this study we examined the effects of the sequential root extracts of Alkanna frigida on the stimulation of the growth of fibroblasts as an aspect of promotion of wound healing by an in vitro study on…
