[ 1 ] - Statistical Evaluation of the Pertinent Parameters in Bio-synthesis of Ag/MWf-CNT Composites Using Plackett-Burman Design and Response Surface Methodology
Green chemistry - also called sustainable chemistry - as the cost-effective and environmentally friendly techniques have been gaining more attention recent years. Here, we introduced a fast, non-toxic and sustainable method to synthesize Ag nanoparticles. Various parameters are involved in the bio-synthesis of Ag nanoparticles/multi-walled carbon nanotubes (Ag/MWf-CNT) composites, including...
[ 2 ] - Preparation and Characterization of High Specific Surface Area γ-Alumina Nanoparticles Via Sol-Gel Method
In the present investigation, γ-alumina nanoparticles with particle sizes less than 10 nm, high specific surface area (351 m2/g), high pore volumes and relatively narrow pore sizes distribution was prepared via sol-gel method in presence of aluminum isopropoxide as an aluminum precursor, distilled water, acetic acid as hydrolysis rate controller and tert-butanol as solvent. They had meso ...
[ 3 ] - Transmission Electron Microscopy Sample Preparation of INCONEL 738 Nickel-Base Superalloy
Size, shape, volume fraction and distribution of embedded g/ phase in g phase has direct effect on strength of INCONEL alloy. Microstructure parameters of INCONEL phases are quantified from microstructure images using transmission electron microscopy (TEM). Different TEM sample preparation techniques were used to study INCONEL 738 alloy microstructure for transmission electron micros...
