One of the obstacles of using the fuel cells in remote areas is the absence of hydrogen infrastructure to supply the required fuel to the unit. However, this can be solved by producing hydrogen on site from water electrolysis. In this paper, the sizing of a standalone hybrid PV/PEMFC system to supply electric power fo…

In this paper, our interest is focused on a theoretical investigation of chains based on Cd1-xZnxS quantum dots inserted in an insulating material. This system, supposed as a succession of flattened cylindrical quantum dots with a finite barrier height at the boundary, is treated with use a novel potential model. The…
Nonlinear optical properties of Pyronin B dye was studied by zscan technique using Q switched pulsed Nd: YAG laser of wavelength 532nm.The dye was prepared in various concentrations 0.3mM,0.4mM and 0.5mM respectively. The dye exhibited negative nonlinearity and saturation absorption in closed and open aperture zscan m…
A high interest developed over time in the fusion nuclear energy field during the last years, especially in producing functional materials that could withstand high temperatures and nuclear irradiations. Analyses upon the fusion reactor walls were performed sequentially, on specific areas of interest, studying the ero…
The monomeric species of Cr(VI) was found to be kinetically active in the absence of 1,10-phenanthroline (phen) under pseudo-first order conditions, whereas in the 1,10-phenanthroline promoted path, the Cr(VI)-phenanthroline complex undergoes a nucleophilic attack by dimethyl sulfoxide (DMSO) to form a ternary complex…
Microbial fuel cell(MFC) is a promising technology in conversion of waste to energy and also providing green environment.In this paper performance of various carbon electrodes in MFC is categorised based on electricity generated working on MFC in various condition. As a new type of electrodes used in MFC which create…
Silver and Titanium Nanocomposite materials are well known as two materials that can effectively eradicate bacteria. Study on the synthesis and characterization of these materials using Horizontal Vapor Phase Growth (HVPG) technique was introduced to combine between Silver and Titanium in a single synthesis. Silver an…
In this research the optical properties of Polyethylene Glycol (PEG)with (0.1,0.2,ÂÂ ,0.8) concentrations mixed with some cellulose derivative polymers as CMC,MC and Xanthan gum added as (0.25 and 0.5) g everyone alone have been studied by spectrophotometer system. From (PEG-MC) blend prepared a solution by using the…
The work is aimed at obtaining highly efficient one-piece units of gas turbine aircraft engines - disks with blades (blisks). Intermetallic γ΄ + γ alloys based on γ-Ni3Al phase of the VKNA type selected as blade material and Ni-based high alloy EP975 selected for discs have similar initial melting temperatures ( ~ 134…
In light water reactors corrosion-induced material degradation is a critical issue not only for material integrity but also for plant radiation field build-up. In BWRs nickel-base alloys, such as A ...
Achilles tendon injuries are common and complex especially in athletes and active people. Healing process occurs via scar tissue formation leading to poor outcomes for patients. Current surgical and non-surgical treatment modalities lead to sub-optimal tendon healing and each of them have complications. Therefore, to…
There is rotational iron loss under the V-junction in the yoke in an actual transformer because not only alternating magnetic field but also rotational and elliptical magnetic field are generated. The rotational iron loss can not be grasped in the standard magnetic measurements because it is assumed that the vectors o…
We investigated characteristics of Fano resonance in asymmetric-double-bar (ADB) metamaterials in the optical region. An ADB structure consisted of a gold nanowire pair with slightly different bar lengths. ADB metamaterials with different sizes were fabricated by a lift-off method, and optical spectra were measured. F…
The mission of JT-60SA is to contribute to the early realization of fusion energy by addressing key physics issues relevant for ITER under the Broader Approach activities jointly undertaken by Japan and Europe. JT-60SA is a complete superconducting tokamak capable of 5.5 MA plasmas during 100 s, which is closest to IT…
The dependence of BaMO3 (BMO: M = Zr, Sn, Hf) materials on reducing critical temperature (Tc) and lattice stress in BMO-doped SmBa2Cu3Oy (SmBCO) films is investigated by comparing the Tc and c-axis length of BaZrO3 (BZO)-, BaSnO3 (BSO)- and BaHfO3 (BHO)-doped SmBCO films with various BMO contents in this report. The T…
This paper describes the characteristics of organic solar cell. Several characteristics impact on the conversion efficiency of organic solar cells was discussed. Recently, organic solar cells are attracting a lot of attention due to flexibility, low cost, light weight and large-area applications, and significant impro…
Many studies of recent decades have specifically examined high-performance carbon materials for application in next-generation batteries. Recently, an innovative technology named solution plasma (SP) has been drawing attention to carbon material synthesis. The most attractive aspect of SP is that, through this technol…
In the last few decades, nanotechnology has been deeply established into human's everyday life with a great number of applications in cosmetics, textiles, electronics, optics, medicine, and many more. Although nanotechnology applications are rapidly increasing, the toxicity of some nanomaterials to living organisms an…
