The paper focuses on corrosion phenomena involving copper, corrosive sulphur and solid insulation of oil-immersed transformers. A study of the available mitigation technique such as passivation to reduce the effects of corrosion phenomena is carried out with the commercially available passivator, Irgamet 39 (Toluiltriazole dialkylamine) (ciba), with concentration of 100 ppm. The paper insulated...
Tobacco (Nicotiana tabacum) was recently shown to detoxify heavy metals by exudation of metals as a metalsubstituted calcite (calcium carbonate) through leaf trichomes. In this paper, we describe the applications of the variablepressure scanning electron microscopy (VP-SEM) system to investigate tobacco trichomes exudates after heavy metal treatment. An energy-dispersive X-ray analysis (EDX) sy...
INTRODUCTION The aim of this study was to evaluate the chemical elements composition of root canal filling materials using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray analysis (EDX). METHODS Eighteen standard polyethylene tubes were filled with the following materials: Sealapex(®), Sealer 26(®), MTA Fillapex(®), Pulp Canal Sealer(®), Endofill(®) and AH Plus(®). After 48 hou...
Aim To compare new remineralizing agents calcium sodium phosphosilicate paste and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste with that of fluoridated toothpaste in remineralization of early carious lesions using scanning electron microscopy and energy-dispersive X-ray (SEM-EDX) analysis. Materials and methods Sixty sound extracted premolars were collected and placed in ...
