While the world because of the attacks last Friday in Paris of his surprise, the researchers trying hard to shed the puzzle pieces together to make a paste that led to the deaths of 129 people and the injury of 99 innocent people.
But the question that the Parisian authorities have been unable to find an answer for it, the type of explosives used in terrorist attacks were the attackers.
Paris prosecutor Francois Mullins told reporters on Saturday that the eight attackers identified, seven of whom were wearing vests full of shrapnel that were designed to create the maximum number of casualties.
Mullins said the key ingredient in the bombs as a chemical called triacetone triperoxide, or TATP, which was originally crystalline powder dangerous for terrorists and for ordinary people.
(White powder unstable)
TATP is very difficult to build simple and diagnosis. It is also incredibly unstable. In fact, only one panel is enough to make it explode with a force 80% higher than TNT.
This material is frequently used in various Trvryssty attacks, including the 2005 and 2006 events noted in London. The bombs that exploded in London in 2005 and 2006 were also contains TATP. The Oklahoma bombing in 2005 and 2006, Texas City, as published in the report by researchers at Northeastern University from this material has been used.
Probably the two materials used TATP are familiar to you. Peroxide Acetone and we must say that a lot in cosmetics and first aid equipment to be used.
Jimmie Oxley, a University of Rhode Island researchers explosives in a single site by sending an email to Insider It said that at the time of this article, it is very high risk of explosion.
(chemical properties)
As mentioned earlier, it is very difficult to detect because it did Nitrogen is a key component of IEDs will not be considered.
Each molecule of TATP only containing hydrogen, carbon and oxygen that all such materials are found in abundance on Earth and are shaped like a ring.
From 1895 to this day that it was discovered the explosive power of a mystery that has scientists. Unlike nitrogen-based explosives, it does not need to blast any fire and flame. The question is if the material in question does not need to blow the heat energy for this purpose is from where?
Kennan in 2005 and after years of research on this matter is that TATP, rather than an incendiary bomb, is more like a massive aerial explosion. When a crystal of the material is barely a shake and motion of the molecules of each gas molecule is split into four.
The pressure that a [half] tons per square inch and then move outwards creates an explosive power 80 times higher than TNT.
After Explosion, gas molecules move energy to the environment and make a shock that caused thousands of the damage.
Is it possible to detect it there?
Scientists are now working hard to find ways to detect TATP action before the explosion to find it.
ACRO Security Technologies is a company that has been established by staff and a "tester for materials made of peroxide" made the Marker is sized and ACRO-PET as it is remembered.
This tester is able to quickly detect a suspicious substance that was found in the place containing explosive peroxide or not. Other researchers are trying to find ways to detect the explosive material found in Antfalsh time without the need to test the substance have direct chemical.
For example, in 2011, researchers at Japan's Hitachi produced a car that took her into the air on a passenger just two seconds could detect any effects of this substance.
A German research team also announced last summer that high volume can detect TATP during transmission. They said their findings so because this matter is too sensitive, usually malicious people to move it within the liquid solution and its characteristic smell liquid is what the researchers hope future security scanners have the ability to diagnosis are.
