1.The most explosive substance
This special honor is actually shared by two compounds: Otto gold Heptanitrocubane. Heptanitrocubane mostly stored in the laboratory, although it is similar to Otto gold, but its crystal structure is more compact, and thus have greater destructive potential. On the other hand, Otto gold as large enough number can have a huge real threat. It is mainly used in solid rocket fuel, shaped charge, or even nuclear weapons detonators. The most frightening thing is that despitethe filmExplosion pictures make it look very easy, first crack fusion reaction, and then a huge, bright radioactive mushroom cloud, but it's not so simple.
2. hardest substance
If you thinkdiamondIs the hardest substance on Earth, if not accurate, it can be considered a good answer. However, the polymerization diamond nanorods is more accurate answer. In fact, it is a nano-scale diamonds, ** it easy to compress, is known to man the hardest substance. Polymerization diamond nanorods is not naturally produced in 2005, it was developed in Germany out of the diamond industry and used in the same capacity, it is more than ordinary wear diamonds.
3. Most of the magnetic material
If the magneto is a small black lump, and that's it. In 2010, it was discovered by iron and nitrogen, magnetic than the previous record holder, it is even higher than 18%, its magnetism is so strong, as well as scientists need to re-examine the role of the principle of magnetism. The substance found in man, repeated assurances by other scientists can reproduce his work since 1996JapanReports have found similar compounds, but other physicists can not copy it, so it has never been officially recognized. If it can be replicated, it will bring a new era of high efficiency electronic and magnetic engine.
4. The most powerful super flow
Ultra Flow is the material (for example, solid or gaseous) state at a very low temperature, it has a high thermal conductivity (it every ounce of the same temperature), and not sticky. Helium 2 is a prime example. 2 cup of helium spontaneously flow up, pouring out from the container, as if it were to decide to leave the same. It can also penetrate into other solid materials, since it is no friction, which makes it possible to pass through the pores of other invisible, while others can not pass through conventional materials. Helium 2 is the planet's most efficient heat conductor, its thermal performance of copper conductor several times. Heat quickly, it is like sound waves in helium flowing inside conducting material 2 is not simply flow from one molecule to another.
5. The most radioactive substances
When it comes to radiation, it is worth noting that the film Simpson plutonium green glow sticks are completely fictional. Radioactive substances does not mean that will be light. Polonium-210 is extremely radioactive, it emits blue light. Former Soviet UnionspyAlexander & amp; Litvinenko, just because they do not have the relevant knowledge and exposure to radiation, cancer shortly thereafterDie. Luminous due to the air around it by the effects of radiation, in fact, it can make the body heat around. If there are some high heat of radioactive material, it has begun to produce the radiation. Be sure to remember that we usually think of radiation refers to nuclear reactor fission reaction or explosion occurs.
