Central and northern asia

Back to Central and Northern Asia: A.D. 601 to 700

In the northern portions of Central Asia, from the Aral Sea and the Syr Darya Valley east to Manchuria, the rulers were the Blue or Celestial Turks (See page 421). They appear to have driven other Turkish tribes westward, including the Ogur and also their former rulers, the Juan-Juan of Mongolia. In the most northeastern part of Mongolia the Uigurs seized control in 744, establishing a capital on the Orkhon River near the site of later Karakorum. The most far flung eastward group of Indo-European (Europoid) tribes were those who reached Chinese Turkistan and were called Tocharians. Their language was written down in this century. The western region of Central Asia, Kashgar, was overtaken by the advance of Islam and due to the energy of the local emir (governor), considerable advance was made against the Turks. The Arabs controlled all of western Turkistan and Afghanistan and the Moslem religion has persisted there until this day.

The Arabs were helped in driving the Chinese out of west Turkistan by the Karluk Turks, who attacked the Chinese from the rear. This Chinese army was finally completely defeated at the Talas River just south and west of Lake Balkhash in A.D. 751 in one of those decisive battles of history. China was not to be influential in Central Asia for six centuries and Buddhism gave way to Islam. Of some importance, too, is the fact that some of the captured Chinese soldiers brought the art of making paper with them to the West. (Ref. 8 , 38 , 19 , 101 )

Padma Sambhava, an Indian guru, brought Buddhism to Tibet, heretofore rife with spirits, demigods and demons. Called to the country by King Trisong Detsan, the guru brought writing to the country and blended native beliefs with the Hindu and Buddhist cults of Tantrism, so that Tibet was under Indian influence after A.D. 750. (Ref. 157 )

Forward to Central and Northern Asia: A.D. 801 to 900

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
