Just hearing the word helium brings thoughts of party balloons and squeaky voices. Helium, however, is serious business. Many fields of endeavor rely on a consistent supply of helium to function. Although many people are unaware of it, we are in the midst of a...

The discovery of Neon by Sir William Ramsay and Morris Travers in 1898 was the culmination of years of scientific research with the purpose of determining the constituents of air. It had already been proven that air consisted mainly of nitrogen and oxygen. By means...

Low energy ion implantation is a technique used to discover the structure of crystals, and the structures of the surfaces of substances. The electrical and magnetic properties of substances can be studied in the same way.The basic principle is that a low energy-emitting isotope...

In one decade, Russia has recovered from the abyss of economic depression to become one of the world's strongest economies, primarily due to the increased demand for natural resources such as oil. Because Russia's economy is so heavily dependent on exporting these resources, their vested...

In explaining how smoke detectors work it is all too easy to launch into technical jargon that would only interest the more intellectual reader. That is the type of reader would would spend hours on the net investigating the mating habits of the Peruvian bat...

With an anticipated Helium shortage and over one third of global reserves, it's little wonder that the world is looking to Russia. The Russians may extract some nine million cubic kilometers of helium annually but the world's least reactive element is still rare on earth...

When one thinks of the well-known element, helium, images of shiny balloons and squeaky voices usually enter their heads. Helium is, however, much more diverse than that. Helium, which is the second element listed on the Periodic Table has a long, conflicting history, unique characteristics...

Calcium is the most abundant mineral in the human body. Considering our bones and teeth are mostly comprised of calcium, that isn't hard to imagine. Of all the calcium in the human body, 99% of it is contained in the bones and teeth. The remaining...

Calcium is a metallic element and the fifth most abundant in the earth's crust. It's an alkaline earth element that doesn't occur freely in nature though it's many compounds are common and we call these compounds "minerals" (such as limestone, marble and chalk) which is...
The chemistry of calcium and its relation to biological function
By: Effie Moore Salem
Calcium is plentiful in the human body and it is plentiful in the earth and rocks and soil. In this capacity it is the isotope calcium 40, the one of the six that is more plentiful; it is the type of calcium making up most...
