It turns out that graphene is a super material with many potential applications – here`s the secret, how to make a strong and "healthy silk." A team of scientists from the University of Tsinghua in Beijing have successfully created a silk that is two times stronger than usual, the result was obtained after taught the worms to consume food pure graphene. To achieve this, they cover the leaves that fed the worms with solution containing graphene nano trubokom. The researchers chose this method mainly because of the simplicity of its application and because it does not heavily pollute the environment.
After conducting special tests on the silk, scientists have discovered that the thread can conduct electricity and has a well-structured lattice, it is not like ordinary silk thread. The carbon atoms in the filament were not visible in the cross sections, most likely because they accounted for only 0.2% of the weight of the obtained silk. However, the final product can withstand 50% more stress at break than the material of the same type grown under natural conditions without the addition of graphene. Scientists still do not know exactly how many graphene hit the silk and how it was destroyed and gone to waste. This direction of study and it is the next step in the study. If scientists understand what and in what proportions anywhere, you are more likely to be able to make even stronger thread.
The experiment proves that it is possible to produce a super silk in large quantities and for this you just need to feed the caterpillars graphene. The team believes that the new material can be used for the manufacture of medical implants and environmental electronics for medicine.
the December 26 in China have started in deal the too long railway pathway on which will be able to move the speed train. The Route is listed as G502 and has connected two high developed in industrial attitude of the city Guanichzhou and Pekin. The Distance between these two cities 2 298 km. The Train преодолеет this distance on velocities in 300 km whole for 8 hours. Usual composition spent on the whole way day, but also that if average velocity on route was 100 km. China constantly modernizes the railway and are chosen area with big passenger turn just. Basically this industrial centres. On given time in China already marketed too long pathway of the speed message.
Today in Ambience composition number 801 successfully went to the first way from station Peking aside Guanichzhou. Departure time 9 mornings. Simultaneously on one and the same route go three trains with difference at time. One came out of Pekin, the second came out of Hanchzhou, but the third came out of city Siani.
After started the new railway general extent speed pathways in China reached 9.3 thous. km, but after pair of the years on calculation she already will as minimum in two times long.
