Strange village is beautiful porn considered the "capital" of the rare substance on the planet

In the periodic table, has ten substances are yttrium, ytterbium, Terbium, Erbium, gadolinium, thulium, scandium, Holmium, Dysprosium, Lutetium possess one common characteristic. That is they are found from a single rock sample ore excavation in an old metal mine in a small village located on the island named Ytterby Resaro (Sweden). 



Yttrium (Y), the rare earth elements were first discovered by Johan Gadolin, has been widely used in LEDs and phosphors, typically the kind of red phosphorus in the tube-cathode is used to project 免費av images inside early television. Yttrium is also used to produce electrodes, electrolytes, electronic filters, lasers, superconducting material, and many other medical applications.

A street was named after Terbium substances found in the legendary rock samples.

Terbim (Tb), then re-used for the semiconductor to produce electronic devices semiconductors such as memory cards, switches ... but most supply this material in the world are used in the production of phosphorus green in the television. Terbium is also used in fluorescent lamps, and the actuators of the system to detect submarines or sensor devices.

Erbium (Er), it has many applications in optics such as laser manufacturing equipment and the image amplifier. Erbium laser capable low penetration allows them to be used in skin care and oral, in which only the skin and the outer surface of the tooth therapy.

Ytterbium (Yb) is primarily used as a stimulant of stainless steel, but the most interesting application of it is in the atomic clock. Ytterbium clock has lower false 2 part 1 trillion, is said to be more accurate than the cesium atomic clock - the kind often used to measure seconds. 

With such great significance, the small village of Ytterby became the only place on the planet to own the amount of the periodic table most. Maybe so, some people have for it is where the most favorite chemist.

All these chemicals are very rare on and extremely difficult to extract. Scientists and chemists have to take dozens of years to explore and study the entire number. In particular, at least four elements have been named after the village of yttrium (Y), Erbium (Er), Terbium (Tb), and ytterbium (Yb). 

Resaro island in the Swedish village Ytterby property modest amount of rare staggering.

History enrolled small village Ytterby in Sweden for the first time in 1787, when a lieutenant army cum chemist Carl Axel Arrhenius discovered a rock sample ore black severe abnormalities in a quarry old near the village. Arrenhus named this ore is Ytterbite form and send it to many other chemists to analyze, in the hope this is a new material is similar to tungsten discovery.

Johan Gadolin, a chemist at the University of Abo Finland, have identified the first rare elements from rock samples of Arrhenius in 1789. This element was called yttrium (Y). For more than 100 later, it has been found to take 9 more elements from each rock sample.

In 1843 Carl Gustav Ytterbite Mosander have found is actually a mixture of three metal oxides. Since then, two new elements have been extracted - it is Terbium (Tb) and Erbium (Er) - both of which are named after the village of Ytterby where they are found. To 1878, the fourth metal oxide sample was discovered by Jean Charles de marignac Galissard, from which the element ytterbium (Yb) were separated pure. 

Gradually, the separation technique is improved, many new elements to continue to be found in the 4-oxide above, bringing the total number of elements extracted from rock samples Ytterbite ten. 

Ytterby quarry where stone was excavated ore samples, now only one sheet to save historic variables.

Interestingly, one of these elements, gadolinium (Gd) was named Johan Gadolin. Even the rock samples also been renamed from Ytterbite to Gadolinite honor of the scientist's merits. 

Mines where mining rock samples are in fact a feldspar mine, but was shut down long ago, and now has been shrouded by trees weeds. Only a small plaque on a rock near the mines left behind a trail of discovery. The discovery is very large, even some of the roads in the village are also in the name of the elements found here.
