The modification is successful if the iron oxide nanoparticles experience a complete alteration in surface properties.
If the iron has a concavity, a projection or molding is created in the workpiece; if the iron has a projection, a groove is dug.
If the iron is left plate down, the legs automatically raise it above the surface.
If the iron is solid, then it ought to form an extraordinary crystal, perhaps a few dozen atomic layers thick, almost perfectly smooth and enveloping the entire star.
It will be a shame if The Iron Lady overlooks that deep anger in favour of exclusive focus on Thatcher as a woman triumphing against the odds.
A clever friend e-mailed me last week with an idea: What if the Iron Bank guy is Arya in disguise?
If the iron itself becomes oxidized to the ferric state, hemoglobin is changed to methemoglobin, a brown pigment incapable of transporting oxygen.
That is much faster than if the iron flows had somehow completely stopped, because then the electric currents generating the field would still persist for 15,000 additional years.
If the iron in the hæmoglobin (or oxyhæmoglobin) molecule is represented as (Fe++ 4, the iron in the intermediate mixed molecules would be (Fe+++) (Fe++ 3, (Fe+++ 2 (Fe++ 2, (Fe+++ 3 (Fe++), and that in methæmoglobin itself (Fe+++ 4.
Granted, the limited palette of film scores sometimes results from the limited abilities of the practitioners, but almost any Hollywood tunesmith could achieve more distinctive results if the iron fist of cliché were to relax just a little.
After 35 years underground, he struggled to conjure enough breath to match his storytelling verve, as if the iron hoops of a whiskey barrel had been strapped around his lungs.
