-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...

• Graphene Oxide, enhanced Hummer technique, EDAX, FT-IR, Thin film, XPS, Raman. oxide (GO) sheets possess a 2D filiform structure and were indigenously synthesized via the methodology. It is accepted that redox approach may be distinctive technique to fabricate GO films as sheet on an expanded scale. Instrumental characterizations showed ready during this study had bi-directional lamellar laye...

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...

The predatory behavior of field-collected Mesocyclops edax on four different kinds of prey was compared under similar and different predator starvation regimes. Unstarved Mesocyclaps did not consume either the ciliate Rhabdostyla or the cladoceran Bosmina. Increasing starvation in the predator increased the probability of ingestion after encounter for both of these prey. The rotifer Asplanchna ...

• Fluorapatites nanoparticles show size distribution from 2 to 22 nm. have a hexagonal structure. different shape according the pH. The ammonia concentration has an influence on morphology and of nanoparticles. Nanoparticles fluorapatite (FAp Nps) were prepared by one step chemical reaction in aqueous solutions. pH system was kept constant at 6 8. FAp Nps characterized with Scanning Electron Mi...

The pathogenesis of acquired cardiac valve disease still remains a matter of controversy. In this work, scanning electron and polarised light microscopic investigations in addition to energy dispersive X-ray microanalyses (EDAX) were carried out on explanted human aortic and mitral valves to determine the morphology and element composition of calcified areas in valvular lesions. Biopsies were t...

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...

Stanene is one of most important of 2D materials due to its potential to demonstrate room temperature topological effects due to opening of spin-orbit gap. In this pursuit we report synthesis and investigation of optical properties of stanene up to few layers, a two-dimensional hexagonal structural analogue of graphene. Atomic scale morphological and elemental characterization using HRTEM equip...
