The use of the power and energy functional in the analysis of the electric circuits makes it possible to appreciate the energetic equilibrium state attained in the circuit at a certain moment. This paper is concerned with a demonstration of the principle of minimum dissipated active power for the steady state circuits under nonsinusoidal conditions. It is shown that the equilibrium state is one...
A high-throughput screening (HTS) method based on fluorescence imaging (FI) was implemented to evaluate the catalytic performance of selenide-modified nano-TiO2. Chemical ink-jet printing (IJP) technology was reformed to fabricate a catalyst library comprising 1405 (Ni(a)Cu(b)Cd(c)Ce(d)In(e)Y(f))Se(x)/TiO2 (M6Se/Ti) composite photocatalysts. Nineteen M6Se/Tis were screened out from the 1405 can...
The polycrystalline Sn added Ni-Zn ferrites were prepared using the conventional sintering method. The monophasic nature of the samples was characterized using X-rays. The elastic behavior has been measured in the temperature range 80-410oC using the composite oscillator method. The values of Young’s and shear modulus are corrected to theoretical density using the method of Mackenzie method. Th...
In this research, Zn-Ni and Zn-Ni/PTFE coatings were electrodeposited from sulfate-based electrolytes. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques were used to investigate the corrosion properties of the coatings. Hardness and tribological behavior of the coatings were examined by the Vickers microhardness testing machine and the pin-on-disc method...
In this research, Ni/Al layered double hydroxide (LDH) was modified by using co-precipitation method to generate Ni/Al-graphite (Ni/Al-GF) and Ni/Al-biochar (Ni/Al-BC). The adsorbents were applied remove Congo Red from aqueous solution. obtained samples characterized XRD, FTIR, BET TG-DTA. XRD diffraction pattern of LDH, Ni/Al-GF, Ni/Al-BC presented the formation composite with decreasing cryst...
MWCNTs composite with UiO-66-NH 2 MOF doped Ni( ii ) ions produced a highly efficient heterogeneous electrocatalyst for the water oxidation reaction.
Metal Matrix Composite (MMC) coatings of Tungsten Carbide (WC) and Nickel (Ni) powder were produced using laser cladding process. A crack free good metallurgically bonded WC-Ni coating about 5mm thick from varying both energy density percent mixture Ni WC. In this study, the microstructure characterised optical microscope (OM), scanning electron (SEM) with EDS, while mechanical properties studi...
Electroless composite coatings used for achieving of high hardness, lubrication properties, non-stick surface, abrasive coating applications that by impregnation of soft and hard particles into Ni matrix. Electroless Nickel-phosphorous coatings properties and performance is greatly affected by the amount of phosphorus in them. The phosphor in this coating usually varies from 1 to 13 percent. In...
