China plans to build a commercial hanging rail lines using trains powered by lithium batteries, which will allow to solve the problem of traffic jams and pollution in scenic areas.
This writes Xinhua.
It is reported that in Guizhou province (southwest China) has completed construction of an overhead monorail line stretching more than 10 kilometers for trains powered by lithium batteries, said a member of the Chinese Academy of Sciences Zhai Animn.

Another similar line in Chengdu – administrative center of Sichuan province (southwest China), is in the process of planning, he added.
Last year, a train powered by lithium batteries with a speed of 60 km/h successfully cruised the 1.4-kilometer trial monoreligious line, developed by the research team Zhai Wanna. The total mileage of the composition as a whole, has 10 thousand kilometers.
The cost of construction of cableways are less than one fifth of the similar construction of the metro system. Besides, such roads do not pollute the environment and do not affect ground targets.

Monorail is a new choice to solve the problem of traffic jams in the cities, as well as a good vehicle for visitors in scenic areas, said Zhai Animn.
Currently, some cities of China, including Hancheng (Prov. Shaanxi, Northwest China), are planning the construction of elevated monorail lines.

Liquid metal has made easier the process of creating nanofilms. This discovery was made by scientists from the Royal Melbourne Institute of technology. Of liquid metal experts have created a film whose thickness was only a few atoms. It is noted that nanofilms of liquid metal can be successfully use to create smartphones and other high-tech electronics.
Scientists got the thinnest material of the metal gallium. It is known that melts even at room temperature. Inventors at the discovery inspired the usual graphite pencil. In the process of writing from behind the thinnest microscopic graphite flakes. Get them easily, as they exist in nature. The staff of the Melbourne Institute have decided to structure, do not occur. The choice of experts fell on a non-toxic alloy of gallium. They were used as the reaction medium and coated its surface with a thin (thickness of a few atoms) oxide film. They have a layered structure, but to separate the layers was very simple. To the liquid metal just need to touch a smooth surface.
Atomic layers is produced by injection into the liquid metal. This is reminiscent of the process of frothing milk or making cappuccino. Scientists emphasize that most atomic films have semiconducting or insulating nature. This makes them suitable for the manufacture of touch panels and displays on smartphones.
