Scanning electron microscopes (SEM), which image sample surfaces by scanning with an electron beam, are widely used for steric observations of resting samples in basic and applied biology. Various conventional methods exist for SEM sample preparation. However, conventional SEM is not a good tool to observe living organisms because of the associated exposure to high vacuum pressure and electron ...

The aim of this study was to investigate the effects of breading materials and two different frying oils on the fat up-take in the fish fillets during frying process. Breaded and non-breaded black pomfret (Parastromateus niger) fillets were fried in sunflower oil and palm olein. Fat content by Soxhelet method and scanning electron microscopy (SEM) was studied. Results from Soxhelet method showe...

Scanningelectron microscopy (SEM) has been utilized  to examine  the morphology and topography alterations  in the surface of Poly(Lactic Acid)(PLA) fabrics due to UV/Ozoneirradiation. In the past decade, a growing attention in the usage of “Green Techniques” in industrial applications has been observed owing to many benefits such as low impurities and their relatively low cost to substitute th...

A statistical continuum model is developed in the present study which uses microstructural information for a two-phase Ti-6Al-4V alloy to simulate microstructure evolution during hot isothermal compression. Current models of prediction often use finite element methods. However, here does not rely onfinite methods and thus can be performed much faster with less computational resources without sa...

Abstract: In the present study silver nanoparticles (AgNPs) were successfully synthesized using aqueous extract of sea weed, Gracilaria corticata. The aqueous callus extract (5%) treated with 1 mM silver nitrate solution resulted in the formation of AgNPs and the surface plasmon resonance (SPR) of the formed AgNPs was recorded at 405 nm using UV-Visible spectrophotometer. The molecules involved...

Functionally graded metal-ceramic composite was fabricated by pressure-less sintering. The pure metallic component (Ti) and the pure ceramic component (HA) were located at the ends of a cylindrical specimen. Titanium and-Hydroxyapatite were utilized as a metallic and ceramic layer. The target sample thickness was 6 mm with radius cylindrical 20 mm. The sample was made from the cylindrical type ...

Starch is one of the cheapest raw materials which can be used in edible film formation. Due to the fact that it is a natural constituent, its incorporation as a food coating does not involve any health risks, although as a barrier material it has the disadvantage of having poor water vapour barrier properties. This could be improved if different non-polar components are included in the starch m...

Present research investigation aims to investigate the prevalence of Clostridium perfringens type A in fresh water fishes [common carp, cat fish, silver carp] obtained from randomly selected dams, freshwater lakes, ponds, retail shops and local markets of Tamil Nadu, India. Intestinal contents from 267 fishes were processed for the isolation and identification of C. perfringens. The ultra struc...

Cadmium oxide (CdO) thin films have been deposited by a locally developed spray pyrolysis method onto glass substrate at 473K. The optical and electrical properties of the as-deposited and annealed films are studied in details. The surface morphology of the samples was studied by scanning electron microscopy (SEM). The SEM micrograph of as-deposited film shows uniform deposition over the substr...
