Synthesis of metallic nanoparticles has attracted by bacterial based production and alternative to physical and chemical approaches. The present work was focused to nominate a bacterial strain for synthesis of potential silver nanoparticles. The target was achieved by screening of 127 isolates from silver mining wastes. A strain designated S-27 found to be(More)
In last few decades nanoparticles have attracted and emerged as a field in biomedical research due to their incredible applications. The current research was focused on extracellular synthesis of silver nanoparticles (AgNPs) using cell free culture supernatant of strain GP-23. It was found that the strain GP-23 belonged to Bacillus species by 16S rRNA(More)
Now a days, significant amount of aluminium alloy are being used to fabricate components such as engine blocks, cylinder heads, suspension control arms, wheels and pistons. In response to consumer demands for the increase in performance, the use of aluminium has grown dramatically in the recent years. So in order to produce a sound LM6 (Al-12%Si) Aluminium(More)
In the recent decades, increased development of green synthesis of nanoparticles is inevitable because of its incredible applications in all fields of science. There were numerous work have been produced based on the plant and its extract mediated synthesis of nanoparticles, in this present study to explore that the novel approaches for the biosynthesis of(More)
Polyethylene glycol (PEG) coated Fe3O4 nanoparticles were synthesized by chemical co-precipitation method. With polyethylene glycol (PEG) as a stabilizer and dispersant. The X-ray diffraction and selected area electron diffraction (SAED) results show that the cubic inverse spinel structure of pure phase polycrystalline Fe3O4 was obtained. The scanning(More)
A SPICE model that predicts the Self Sustained Operation (SSO) used in programming of a Floating Body Cell (FBC) is presented. This model, which is calibrated to the contributions of the MOS, BJT and Impact Ionization (II) currents, is demonstrated to accurately predict the static and switching characteristics of the cell. Accurate modeling of device(More)
The effects of bandgap narrowing due to stress generated during Shallow Trench Isolation (STI) are analyzed. Reverse-bias junction leakage and capacitance measurements are correlated to results from device simulation. A locally varying stress dependent bandgap model is implemented to understand the influence of stress effects. Increases in both junction(More)
