From the United States at the Los Alamos National Laboratory's explosives chemist Dawei·chaweisi (David Chavez) synthesis of a new type of molecule, one of which has a unique combination of three-ring structure. It is understood that these new materials are likely to usher in a new kind of explosive, not only provides higher power output, while security has been enhanced.
Dawei·chaweisi says: "is a general trend, material properties, the higher their impact, sparks and friction damaging stimuli is more sensitive. However, the Los Alamos lab interested in the creation of a does not follow the trend of materials science. "The results of this research have been published in Germany famous on applied chemistry journal Angewandte Chemie International Edition.
Being explosives science and technology, a member of the team, Dawei·chaweisi in this article are described in detail in two has never been synthesized materials, the first is a diamine DINITRO compounds, its performance is a bit closer to the traditional high-performance materials, but it is not sensitive to shocks, spark and friction, so this material is actually very safe.
The second is a being collectively referred to as the new heterocyclic system of three-ring 1,2,3,4-tetrazine, its performance and security are very much like traditional materials. This system formed the basis of similar synthetic materials in the future.
Dawei·chaweisi said: "basically, these materials can be used in high performance materials is used in all places. They are likely to place explosives and propellants (these two things cannot meet today's security requirements). With the passage of time, and security becomes more and more important, especially in the propellant, some military and mining industry and so on. "
In his view, found a need volume, to maintain a high performance, non-sensitive and are not adversely affected by the sharp changes in temperature of new materials is necessary. Just Cavalli iPhone 6
In the past two years, in order to realize their own ideas, and Dawei·chaweisi have been conducted related research. He found a composed of carbon, hydrogen, nitrogen and oxygen, all the basic components of explosives, such as the unique molecular arrangement. Bis p-diamine compounds insensitive properties mainly from hydrogen bonds between molecules, an effect somewhat similar to the glue. Just Cavalli iPhone 6 Case
The hydrogen bonds are very strong glue, can keep the molecule intact, but also enough to make the weaker elements in the damaging stimulus apart is not broken down by the break (that is, not exploded), thereby increasing security.

Dawei·chaweisi: "how to isolate and confirm the correct structure, we have a lot of different ideas. We learn from a failed experiment, will succeed in the end. Los Alamos lab the most great thing is to promote the cutting-edge science, doing something no one has ever done. "
