Description:

A black powder with amazing properties indicating that we may not be very far from realizing what we've been reading about in science fiction novels. Just add a pinch of this powder to anything to make it more than100 times stronger. This black powder actually consists of tube shaped molecules made of carbon. Like other forms of pure carbon it gets its strength from the strong bonds between carbon atoms. Adding only a few grams of this powder can greatly improve the quality of almost any product while reducing its weight. So we can have stronger buildings cars and even it is possible to weave super-strong bulletproof fabric. The Carbon Naotube promises to revolutionize many industries. Still a hot topic in the world of nano-technology since it was discovered in 1991 the continuous production of carbon nanotubes remains a challenge for scientist worldwide. Iran has managed to take a leap. In the research institute of petroleum industries it has taken the scientists 10 years to produce these nano tubes. The continuous production of up to 20 kilograms of Carbon Nanotubes is now possible in the institute using the Iranian designed reactor which has slashed the time required to synthesize this amazing product to 15 times less than similar procedures worldwide. The ten member team working on this project prepared to share the technical know-how they've acquired in order to heat hydrocarbon gases to 800 to 1000 degrees Celsius with the right catalyst to start the formation of the tubes. Molecules one-sixth the weight of steel but 100 times stronger. In fact the strongest material ever discovered with huge applications The successful completion of the pilot project to synthesize continuous carbon nanotubes will now be taken to the next level. Iran's private sector is already negotiating to establish units capable of producing up to 100 kilograms a day only to imitate what mother nature ha been doing for 100s of millions of years… engineering strength into the bodies of molecules one atom at a time.

Just how small are atoms? And what\'s inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world. Lesson by Jonathan Bergmann, animation by Cognitive Media.

What is matter? The simple answer is that matter is anything that has mass and occupies space. But, in today\'s educational science video for kids, we will learn about the 3 types of matter; solid, liquid and gas...as well as what matter is made of. #scienceforkids #educationalvideosforkids #matter SUBSCRIBE https://tinyurl.com/yckbu4r5 WATCH MORE https://tinyurl.com/3ksmu7d9 FREE EDUCATIONAL GAMES FOR KIDS! https://www.brainstar.com/ Turtle Diary (Brain Star) creates educational videos for children about math, science, reading, writing, social studies and more!
