-Multilayer ceramic chip capacitor CDR-05 (MIL part number) is one of the most used parts in ISRO’s satellite program. Cracks evolved in ceramic chip capacitors CDR-05 (size: 1825and dielectric: X7R) of two different makesduring soldering process are studied in this paper. It has been observed that CDR-05 capacitors of one particular make (Manufacturer-A) more prone to crack during soldering on...

In the present study green synthesis of silver nanopartiles (SNPs) is prepared by using aqueous stem bark extract of Adansonia digitata (L.) as a reducing, stabilizing and capping agent. The synthesized SNPs are characterized by UV-VIS Spectroscopy, FTIR, XRD, AFM, SEM with EDAX and TEM. Validation of SNPs was performed on 07 bacterial species and 05 fungal species. For preliminary conformation...

Electron microscopy (EM) is a useful tool for detailed ultrastructural analysis of microorganisms. Both scanning electron microscopy (SEM) and transmission electron microscopy (TEM), which provide information about surface and intracellular changes, can be used for studying the effects of antimicrobial agents on microorganisms. EM has previously been used to study the ultrastructural basis of t...

The n-type tungsten oxide (WO 3 ) polycrystalline thin films have been prepared at an optimized parameters (0.20M, 5 ml and 500oC) using jet nebulizer spray pyrolysis (JNSP) technique. Such prepared WO 3 films were characterized by XRD, SEM, EDAX, UV-vis from I-V. The XRD pattern of the optimized WO 3 film reveals the monoclinic structure. The SEM and EDAX images shows that the surface morpholo...

We used an aqueous leaf extract of Memecylon edule (Melastomataceae) to synthesize silver and gold nanoparticles. To our knowledge, this is the first report where M. edule leaf broth was found to be a suitable plant source for the green synthesis of silver and gold nanoparticles. On treatment of aqueous solutions of silver nitrate and chloroauric acid with M. edule leaf extract, stable silver a...

The potential of economically cheaper cellulose containing natural materials like rice husk was assessed for nickel adsorption from aqueous solutions. The effects of pH, contact time, sorbent dose, initial metal ion concentration and temperature on the uptake of nickel were studied in batch process. The removal of nickel was dependent on the physico-chemical characteristics of the adsorbent, ad...

Abstract- Rasa Bhasma is a Herbo-Mineral preparation mentioned by Shri Anantadeva Soori in his textbook Chintamani the context of Parada Marana. Owing to its Hepato-protective indication, it was prepared as per conventional method and subjected various physico-chemical parameters, assessment inorganic elements, SEM EDAX ICP-OES for determination Mercury. Results revealed that tasteless, grey co...
