Stress Corrosion Studies of Titanium Dioxide Particulate Reinforced ZA-27 Metal Matrix Composites
The stress corrosion resistance of ZA-27 TiO2 metal matrix composites MMC's in high temperature acidic media has been evaluated using an autoclave. The liquid melt metallurgy technique using vortex method was used to fabricate MMC's. TiO2 particulates of 50-80 µm in size are added to the matrix. ZA-27 containing 2, 4, 6 weight percentage of TiO2 are prepared.
Stress...

A Method to Calculate Functions of the Product of G and F Used in Wilson's GF Matrix Method
Wilson's GF matrix method is generally utilized to obtain normal vibrations and normal coordinates of molecules. The function of the product of G and F in Wilson's GF matrix method is also a key to determine the line-shape function (LSF) which expresses molecular absorption or emission spectra. In this paper, the method for calculating the function of the...

Corrosion Characterization of Aluminium 356 Hybrid Composites in Neutral Chloride Medium
Hybrid composites are the composites which contain two different reinforcements in them. One of the reinforcements will be added in different quantities and another one will be added with same quantity. In this work hybrid composites of aluminium 356 are manufactured by adding fly ash and silicon carbide particulates.Composites are manufactured by liquid melt...

Significance of Amphiphilic Block Copolymer Micelles and its Characteristics
Amphiphilic block copolymers (ABCs) have been used broadly in pharmaceutical applications. One of the most widely used drug delivery systems is the self assembly of ABCs carriers in micelle forms in aqueous environment. Block copolymers have low toxicity and due to their nontoxic properties and surface-activity they have found application in the areas of biomaterials,...
