Nano-diamonds can be called "Transformers" and add new medical uses.

With powerful electron beams, scientists have shown that nano-diamonds in treated coal can only exist for a few seconds and then become unexciting carbon. The photo was taken with an electron microscope, and the black spots were the nano-diamonds in the coal.

The electron beam emitted by the microscope condenses hydrogenated carbon atoms, some of which have a lattice-like nanodiamond structure. The photo shows a nano-diamond (black spot) that is converted to coal.

Nano-diamonds can be used in a range of industrial applications, and their use in medical research has expanded to include chemotherapy, increase bone growth and improve dental implant tolerance. Nano-diamonds are small in size and invisible to the naked eye and can be used to combat diseases caused by bone loss such as osteonecrosis.

Beijing time on the 27th, according to foreign media reports, according to a new study, not all diamonds can be "always long", some diamonds will disappear in just a few seconds, this diamond is the so-called " Nano diamonds." This research finds that it is obviously inconsistent with the theme song of Bond film sung by Sally Bessey in 1971 and the famous slogan "Diamond is a long-lasting, a eternal rumor." The diamond's English name "diamond" means "unbreakable" in ancient Greek.

With powerful electron beams, scientists have shown that micro-diamonds in treated coal can only exist for a few seconds and then become unexciting carbon. Scientists at Rice University in the United States discovered this phenomenon of nanodiamonds after chemically treating the carbon in coal to make it soluble. Nano-diamonds can be used in a range of industrial applications, and their use in medical research has expanded to include chemotherapy and bone growth.

The chemist Ed-Billups and Yanqiu Sun (transliteration) pioneered the discovery of nano-diamonds in unformed hydrogen-filled graphite layers. When photographing close-up photographs of coal using an electron microscope, they found that the energy of the electron beam emitted by the microscope condensed hydrogenated carbon atoms, and some had a lattice-like nano-diamond structure. Billups said: "The energy of the electron beam is very large. In order to strip the hydrogen atoms, you need to use amazing energy." The energy of the electron beam strips the weak hydrogen atoms and triggers a chain reaction between the graphite layers of the coal.

According to a research paper published in the Journal of Physical Chemistry Letters of the American Chemical Society, the chain reaction forms diamonds with a width of 2 to 10 nanometers. Billups and Sun Yanqiu found that most of the nano-diamonds quickly disappeared under the influence of electron beam energy. In the photo, they recorded these changes for about 30 seconds. Billups said: "These miniature diamonds are not stable and will soon be converted into the initial material - anthracite."
