In this work, we report on the vapor-based synthesis of molybdenum disulphide (MoS2), which is one of the most widely studied two-dimensional (2D) layered materials since the large body of work conducted on the quintessential layered material, graphene. In addition, we have fabricated and characterized a MoS2photodete…
Hard nonlinearity or hysteresis effect is the main obstacle in most smart material based actuators which makes their optimal usage impossible. Thus, it is essential to develop a comprehensive strategy for modeling and control in order to mitigate this hysteresis nonlinearity. This paper investigates the viability of t…
Conditional connectivity and conditional fault diameter have been proposed as two important parameters in estimating the fault tolerance property of interconnection networks. In this paper, we consider the conditional fault tolerance properties of (n, k)-star graphs through investigating the conditional connectivity a…
This experiment evaluated the effect of calcia alumina and alumina silica that formed as side products involved in metal mixture of aluminium foam. These compounds are formed from additional calcium carbonate and silica in the mixture. Calcium carbonate (CaCO 3 ) roles as a blowing agent source of carbon dioxide (CO 2…
The effect of CrO 3 sealing time on anodized aluminum alloy has been investigated. A1 2024-T3 were used as substrate. Anodizing was carried out using chromic acid. CrO 3 sealing was conducted in CrO 3 solution for 30, 60, 90, 120 and 150 minutes. As comparison, other specimens were also prepared as anodized and boiled…
Ternary chlorides may be prepared conveniently from aqueous solutions or acetic acid, provided they are congruently soluble in the solvent or they may be prepared by heating together appropriate amount of anhydrous halides. The synthetic route followed here starting from the binary chlorides of alkali metal (ACl) and…
The way of the account of nonlinearity of deformation of concrete and reinforcement bar and cracking in concrete in finite element analysis of reinforced concrete columns of rectangular section is described. The column is made from solid eight nodes elements modelling concrete, and the rod elements modelling reinforce…
Here we report on the impact of annealing and oxidation processes for silicon solar cells performed at low temperatures, in terms of how recombination properties at the surface and within the emitter are modified. Results from this experiment show that bulk gettering of interstitial iron impurities is also enhanced fr…
This paper covers the investigation of the microscale behavior of Pt nanostrucures fabricated by atomic layer deposition (ALD) at elevated temperature. Nanoparticles are fabricated at up to 70 ALD cycles, while congruent porous nanostructures are observed at > 90 ALD cycles. The areal density of the ALD Pt nanostructu…
Estimation of the minimizer of the Thomas-Fermi-Dirac-von Weizsacker functional of NaCl crystal lattice is calculated by making use of a direct method we have developed recently. The method is referred to as direct method for the reason that in the course of the calculation of the estimation, we do not derive the Eule…
Przedmiotem badań były napawane ostrza narzędzi maszyn rolniczych do uprawy gleby. W metodzie napawania płomieniowego użyto proszku stopowego na osnowie niklu w mieszaninie z różną zawartością proszku węglika wolframu. Badania polegały na wykonaniu pomiarów twardości, makro i mikrostruktury, analizy chemicznej napoiny…
Orbital angular momentum of vortex electromagnetic waves has the potential to overwhelmingly increase the system capacity for radio communications. To explore the performance of the novel multiplexing system, the influence of both detection schemes at the receiving side and power allocation methods at the transmitting…
Organolead halide has attracted great attention for application in perovskite solar cells due to its high power conversion efficiency (PCE) of up to 20.1%. One of the most common perovskite materials is lead based reagent. In this research, we have synthesized organolead halide with lead extracted from solder wire. In…

Study related to the production process of collagen extracts lately grown rapidly. Scientists are working to find a production process that efficient and effective, but the impact is very low in human. The production process of collagen extract performed by developed countries more applying chemical processes in order…
The single crystal of L-Lucinedoped NickelSulphateHexa Hydrate (NSH) was grown from slow evaporation technique for different molar concentrations, viz., (0.2 to 1 mole% in steps of 0.2). The crystallinty, cell parameter and cell volume of the grown single crystals was estimated by powder X-ray diffraction studies. The…
The work is devoted to experimental research of parameters of prismatic aggregate at static loading. The data of experimental researches allow to use them in the design of three-layer structures in space, aviation techniques, as well as in construction and machinery that is of interest for technical workers and design…
A twisted carbon nanoribbon was deposited onto multicoated silver thin film using RF-PECVD method at relatively low radio frequency (rf) power, 8 watt. Plasma formation in the chamber is strongly influenced not only by rf power but also by methane flowrate hence in order to get optimum condition it need to be appropri…
This research studies the effects of particle grain size of reinforcing material on mechanical properties of composite material. A polymeric blend of epoxy resin and poly sulphide rubber [Ep 70% + PSR 30%] was used as a matrix, and nanozirconia powder (Nano-ZrO2) as a reinforcement material with various grain sizes (2…
The isotope 99Tc is an important fission product generated from nuclear power production. Because of its long half-life (t1/2 = 2.13 ∙ 105 years) and beta-radiotoxicity (β⁻ = 292 keV), it is a major concern in the long-term management of spent nuclear fuel. In the spent nuclear fuel, Tc is present as an alloy with Mo,…
