Example 1: Composition of an Atom Iodine is an essential trace element in our diet; it is needed to produce thyroid hormone. Insufficient iodine in the diet can lead to the development of a goiter, an enlargement of the thyroid gland (Figure 2). Figure 2. (a) Insufficient iodine in the...
The pursuit of atomic precision structure of porous covalent organic frameworks (COFs) is the key to understanding the relationship between structures and properties, and further developing new materials with superior performance. Yet, a challenge of how to determine their atomic structures has always ...
elements are particularly healthy, Iodine-131 is particularly nasty, since one's thyroid gland does its best to suck up iodine, radioactive or not. The tablets fill up the rocketeer's thyroid with safe non-radioactive iodide, so the thyroid won't stuff itself with Iodine-131 and become ...
While none of the fission fragment elements are particularly healthy, Iodine-131 is particularly nasty, since one's thyroid gland does its best to soak up iodine, radioactive or not. Thyroid cancer or a hoarse voice from thyroid surgery might be common among atomic rocket old-timers. The ...
