solutions by some azole derivatives has been investigated using weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) techniques. Inhibition was found to increase with increasing concentration of the azole derivatives but decreased with r…
This article is devoted to the development of new polymer additives for the process of copper electroplating from sulfate solutions with a purpose of copper coating obtaining. Copper coating, obtained from electrolytes in the presence of DEA-PAN additives and thiourea are of high-quality: they are thick, fine-grained,…
Mechanical Engineering Integral University Lucknow,India Abstract- In the present study a modest attempt has been made to develop aluminum based silicon carbide particulate Metal Matrix Composites(MMC) with an objective to develop a conventional low cost method of producing MMCs and to obtain homogenous dispersion of…
This Master thesis investigates mechanical failures of electrofusion joints. This type of joints are used for weld high density polyethylene pipe systems where tting and pipe will be welded together by the heat caused by the resistance of the copper cables to electric current. There have been some failures where a bri…
Nanocrystalline pure and Gd 3+ doped CoWO4 nanostructures were synthesized by single step chemical precipitation technique. The framework substitution of Gd in CoWO 4 nanoparticles was established by X-ray diffraction (XRD) and Fourier transform infrared (FT- IR) techniques. XRD pattern reveals the pure and doped CoWO…
Usually the quality of tea is sensed by tea tasters and classified by smelling and very few devices are available to calibrate the flavour. In this paper, resistance change of W doped ZnO nanostructure chemoresistor pellet sensor was investigated in an environment of different types of tea aroma infusion with an objec…
Recent progress in the synthesis of bulk-derived nanosheets has increased the availability of high quality nanosheets with a variety of structures, chemistries and properties. These unique materials can be employed to construct both well-ordered films and heterostructures, as well as novel mesoscale assemblies that pr…
The present paper reports on the development and optical analysis of PVA and Eu 3+ : PVA polymer films. For reference PVA film, the XRD spectral profile has been carried out and found that this polymer possesses a semi crystalline nature. Spectral analysis for different concentrations of (0.1, 0.15, 0.2 mol %) Eu 3+ :…
Polyurethane prodrugs with different drug contents were synthesized using polycaprolactone, hexamethylene diisocyanate and ciprofloxacin. The thermal analysis of the materials was carried out by DSC and TG. Results showed that the crystallinity of the materials reduced as the drug contents increased and the materials…
SummAry herein we examined the toxicity, penetration properties and ability of Fe 2 o 3 ·nh 2 o magnetic nanoparticles extracted from silt of the Borovoye lake (Krasnoyarsk, russia) to bind an antibiotic. Experimental studies were carried out using magnetic nanoparticles alone and after antibiotic exposure in tissue s…
This article delves into the importance of coupling heat and moisture for clothing heat and moisture comfort, summed up the common test principle of porous textile’s dynamic heat-moisture measuring instrument, and reviews the recent progress of it. Combination of the above analysis, the paper puts forward views that t…
In this paper we employ non equilibrium thermodynamics of fluxes and forces to describe magnetization and heat transport. By the theory we are able to identify the thermodynamic driving force of the magnetization current as the gradient of the effective field ▿H*. This definition permits to define the spin Seebeck coe…
dilauroyl-sn-glycero-3-phosphatidylnucleosides (DLPNs) based on uridine (DLPU) and adenosine (DLPA) were first formed at the silica–water interface. The PAMAM/DLPN layers were then exposed to short oligonucleotides, polynucleotides and single stranded DNA (ssDNA). The interfacial properties were characterized using qu…
A series of metal doped graphitic carbon nitride (Fe2O3-g-C3N4, Fe3O4-g-C3N4 and MnO2-g-C3N4) photocatalysts were synthesized using a hydrothermal method. The catalytic performances of these materials were evaluated in liquid-phase heterogeneous activation of peroxymonosulfate (PMS) for decomposition of phenol and pho…
Composites are being used in many areas of ship construction to improve the performance and prepare the ships for the challenges of the future. Marine structures are to be stiffer, stronger and tolerant to corrosion and dynamic loads. Sandwich composites further enhances these advantages by using thin layers of GFRP o…
Using the Spray pyrolysis method, Zinc thioindate (ZnIn2S4) and In rich-Zinc thioindate thin films were deposited on a glass substrate with the molar ratio of Zn/In = 4.6, 3.1 respectively using ZnCl2, InCl3 and SC(NH2)2 as precursor m aterial with substrate temperature of 350 ˚ C. F rom XRD analysis, the position of…
One of the most important subjects in power systems is an optimal and economic design of power transformers. In this paper, determination of turn ratios for power transformers that are directly connected to generators is evaluated considering reactive power generation and its impact on the optimal turn ratio selection…
The objective of analysis was to check fatigue life of Air Receiver for cyclic pressure service and impact loading service in accordance with ASME Section VIII, Div-2 Part 5 Ed. 2013. To study the stress levels, finite element based stress analysis is carried out. The study is conducted to determine the stress levels…
E xperimental investigation s are conducted to study dynamic fracture behaviour of sedimentary, igneous and metamorphic rocks. The notched semi - circular bending method (NSCB) has been employed to determine fracture para meters using a split Hopkinson pressure bar (SHPB) . The time to fracture, crack speed and veloci…
Scanning transmission electron microscopy (STEM) provides sub-angstrom, atomic resolution images of crystalline structures. However, in many applications, the ability to extract information such as atom positions, from such electron micrographs, is severely obstructed by low signal-to-noise ratios of the acquired imag…
