particles above 50nm in steel, but identifying precipitates below this size was not clarified. However, from this analysis conducted on carbon extraction replicas using an FE-SEM, it was proven that Nb can indeed precipitate as particles below 50nm (as low as 10 nm).
FE-SEM was successfully used in characterizing Nb precipitate as low as 10 nm (comparable to the capabilities of a TEM). It was
1. Introduction
Ammonia (NH3) is one of the most familiar compounds of nitrogen and hydrogen as well as one of the world's most valuable industrial and agricultural chemicals. Ammonia is used throughout the industrial world as a valuable fertilizer.
Ammonia and its compounds, primarily ammonium nitrate and other ammonium salts, replenish nitrogen in depleted soils. This greatly increases y
Granulomas (miscropic nodules), consisting particles, live and dead cells, and debris and could impair cellular and physiological (gas exchange) lung functions and give rise to fibrosis, more defined nodules, and other lesions.
Fibers are generally of more health hazard than other forms of particulates. It is well established that the pathogenicity of a fiber in the lungs directly correlates
