The final yield for all compounds was about 30 - 50%.
Xray powder diffraction showed that these compounds were amorphous.
Due to the presence of CoII as heteroatom all compounds were blue coloured.
The SEM image of supported CoW11Co (Fig. 4a) is different from those of the Ln compounds.

Introduction The nickel and nickel based alloys are used in the wider range of applications as corrosion resistant alloys, resistance heating elements, controlled expansion alloys and elevated temperature creep resistant alloys.
The Nickel-molybdenum alloys are better corrosion resistant in reducing conditions than nickel or cupronickel alloys [1-5].
The aim of the paper is the study of the weldability of Nickel sheets using an electron beam welding method.

The LCMO compound has been synthesised using sol-gel route.
Therefore, this project is aimed to investigate the structural and electrical properties of La0.7Ca0.3MnO3 (LCMO) nanocomposites incorporated with the different ratios of α-Fe2O3 nanoparticle.
Hence, the calcination of the compound was performed at 500°C and then sintered at 800°C to obtain the single phase of LCMO compound.

Pulse Power Supply Transistor-RC compound pulse power supply is applied in the paper and a group of blasting capacitances is connected between two polarities in parallel.
Because free carbon content is high it is easy to form titanium carbide in kerosene so that it is difficult to machine Ti alloy.
In contrary, because free carbon content in de-ionized water is low it is easy to machine Ti alloy and machining efficiency is higher.
Aiming at a cylinder workpeice, the positioning method illustrated in Fig.5 is applied under the foundation that tangent hole accuracy is analyzed,.

The important compounds in the plant extract are hydroxyl and carbonyl groups which act as reducing agent as well as stabilizing agent.
Most of the plants contain an ample of free radical scavenging molecules such as phenolic compounds, nitrogen compounds, vitamins, reducing sugar, terpenoids and some other metabolites that are rich in antioxidant activity [2].
Phenolic compounds are well-known phytochemicals found in all plants.
However, since Folin-Ciocalteu technique is simply a redox reaction, it is actually quantify not only phenolic compounds but also other compounds that have reducing power such as amino acids, carbohydrates, ascorbic acids and others [10].
Extraction occurred as solvent diffused into plant tissues and solublized compounds with similar polarity [17].
