Metallic iron in cornflakes

Persorption of metallic iron particles.

Large, solid, undissolved food particles instantly enter the body from the intestinal lumen. We examined this phenomenon which we called 'persorption'. Such large particles are kneaded between the cells into the subepithelial region through the epithelial cell layer. Transport from the intestinal wall is via the portal system and by means of the chyle (Fig. 1). Starch granules with a diameter r...

Magnetic moment of iron in metallic environments

Rare-earth iron nitrides are emerging as an important class of magnetic materials. In certain rare-earth iron compounds, the insertion of small atoms such as nitrogen and boron has resulted in significant changes in the magnetic properties in the form of higher Curie temperatures, enhanced magnetic moments, and stronger anisotropies. In an attempt to understand some of the above, we have focuse...

Metallic iron for safe drinking water worldwide

A new concept for household and large-scale safe drinking water production is presented. Raw water is successively filtered through a series of sand and iron filters. Sand filters mostly remove suspended particles (media filtration) and iron filters remove anions, cations, micropollutants, natural organic matter, and micro-organisms including pathogens (reactive filtration). Accordingly, treatm...

Metallic Iron for Water Treatment: Lost Science in the West

Voltaire (1694-1778), the French philosopher said: “There are many ways to waste own time: Doing nothing, doing the wrong thing, doing the good thing at the wrong time” (own translation). The situation is quite different if the time is robbed by someone else or even by a professional mistake. There is a clear evidence that researchers on metallic iron (Fe0 termed as zero-valent iron) for water ...
