COMPARATIVE STUDIES OF SCANNING ELECTRON MICROSCOPY AND TRANSMISSION ELECTRON MICROSCOPY

A study was conducted on the lingual tonsil of six male crossbred goats of six months of age. The lingual tonsil could not be identified macroscopically but in histological sections aggregations of lymphocytes were seen within the core of vallate papillae present in the root of tongue. The stratifie[r]

Minusculum (Lebour) Balech is one of four subgenera of the genus Protoperidinium Bergh 1881. Only five species of this subgenus have been discovered worldwide, most of which are distributed in cold waters. In this study, Protoperidinium anomaloplaxum (Balech) Balech is reported from Vietnam and thus[r]

Nanotechnology has recently emerged as an elementary discipline of science that explores the interaction of synthetic and biological materials. Nanotechnology is currently employed as a tool to exploit the darkest avenues of medical sciences to combat dreadful diseases caused by drug resistant micro[r]

For this study, different volume fraction (vol.%) of particulate alumina (Al2O3) reinforced aluminium alloy (Al 6061) with 5 vol.%, 15 vol.% and 25 vol.% are produced by powder metallurgy method. These samples were subjected to biaxial stresses in order to investigate the behaviour of the metal matr[r]

Collagen from fish is attracting a lot of attention thanks to its high absorbance ability, biocompatibility as well as non-religious obstruction and cheap sources. It could be applied in many fields, for example: food, cosmetic, or biomedicine. Using of collagen also helps reduce the environment pol[r]

n this work, the SnO2 nanofibers (NFs) were directly synthesized through a electrospinning method following the annealing treatment process at 600 °C for 3h. The morphological, compositional, crystal properties of material were characterized using field emission scanning electron microscopy (FESEM),[r]

Abstract: SnO2gC3N4 composites as photocatalysts with various weight ratios of SnO2 and gC3N4 were synthesized using a facile method through heating of mixtures of Sn6O4(OH)4 and melamine. The asprepared samples are denoted as MSC1:n where n = 5, 6, 7 corresponding to the weight ratios of Sn6O4(OH)4[r]

In this work, the hydrothermal growth of ZnO nanorods (NRs) on plastic PVC substrate is presented. It was shown that ZnO NRs with high density and high crystallinity can be successfully grown by implementing saturated nutrition solution of zinc nitrate hexahydrate (Zn[NO3]2·6H2O) and hexamethylenete[r]

The development of nanotechnology interests the researchers for synthesis of nanoparticles with various bio-applications. The green synthesis of copper nanoparticles using Momordica charantia fruit extract acts as both reducing and capping agent. The biosynthesized CuNps were characterized by using[r]

Polypropylene/ maleic anhydride /organic montmorillonite nanocomposites (PP/ MA/ Org-MMT) have been prepared via direct melt intercalation in an internal mixer. Maleic anhydride (MA) was used as a compatibilizer to improve the dispersability of the clay. The structures of nanocomposites have been ch[r]

Nanocrystalline ceria with high surface area and mesoporosity was prepared by template-assisted precipitation method. The method of preparation was facile, using low-cost reagents and could be performed on a large scale. Cerium oxide support was characterized by Brunauner – Emmett - Teller (BET), X-[r]

The microstructure of cast Al-4Si-Mg reinforced with fly ash particles at various particle contents has been studied. The composites were fabricated by stir casting process and characterized by optical microscopy, image analyzer, scanning electron microscopy and hardness measurements. The results sh[r]
