11、 multinational World Heritage application.The starting point of the corridor and the entire Silk Roads network isXian,inShanxiProvince.Further west on the Silk Roads,the geography gradually changes from wild deserts to high,snow-capped mountains to vast grasslands as the routes pass through theTians
12、hanMountainsand emerge in the valleys ofCentral Asia.Although the Changan-Tianshan corridor of the Silk Roads ends here,the network continues westwards until it reaches theMediterranean.The corridor began to develop in the 2nd century.Assigned by the emperor,the ambassador Zhang Qian journeyed from
13、Changan toCentral Asia,seeking to build bridges between the Han Dynasty and the Western Regions.Following Zhangs efforts,trade routes took shape and relationships were strengthened between the major powers of the time,with the routes network reaching as far as theRoman Empire.Economic activities alo
14、ng the routes network were not limited to trade in silk.They contributed many other items to the marketplace of goods.The routes were busy with camels carrying loads of goods and businessmen selling everything imaginable.Chinas exports included silk,porcelain,ironware and tea,while horses,jewellery,
15、spices and grapes were all imported over vast distances from the West.In addition to trade exchange,the network served as a bridge for cultural exchange which shaped the evolution of science,art,technology and many other areas in societies along the network.Astronomy and mathematics were introduced

22、ere are still a few more steps before these materials can become high-performing.However,he says,“This will be used in the not too far future.”Thermoelectrics are semiconductor devices placed on a hot surface.That gives them a hot side and a cool side.If a device allows the hot side to warm up the c
23、ool side,the electricity stops flowing.A devices success at preventing this,as well as its ability to conduct electrons,feeds into a score known as the figure of merit,or ZT.Researchers have produced thermoelectric materials with increasing ZTs.The record came in 2014 when Mercouri Kanatzidis came u
24、p with a tin selenide with a ZT of 3.1.Yet the material was too fragile to work with.“For practical applications,its a non-star-ter,”Kanatzidis says.Getting through that door will still take some time.The tin selenide the team makes is mixed with Na,creating a“p-type”material that conducts positive
25、charges.To make working devices,researchers also need an“n-type”version to conduct negative charges.Zhaos team is now working on making an n-type version.Once successful,researchers should have a clear path to making a new generation of super-efficient thermoelectric genera-tors.Those could be insta
