Anti–Shock, Anti–Heat

Scientists from the National Institute of Advanced Industrial Science and Technology, Japan have invented a shock–resistant material that can withstand extremely high temperatures. Researchers hope that this invention could be used in the engines of spacecrafts and cars to prevent them from heating.

The material made out of carbon can flow and stretch slowly like thick honey and would spring back to its original form. It looks like a metal sponge and its structure consists of trillions of entangled nanotubes that make it sturdy. According to the scientists, the carbon nanotubes were grown in a mixture of silicon, iron and water. These tubes have a diameter of 5 nanometres (one nanometre is the billionth of a metre) and it can retain its form and function within the temperature range of -196° and 1000° C in an oxygen–free environment.

Inventors swear by its resilience and are confident that it would help in designing engines and fuel tanks for spacecrafts, rockets and cars.

The most wonderful and precious element of universe is the human life which can only be guided by the right knowledge and right attitude. So, here is an ocean of knowledge, both in English and Hindi encompassing every detail and each facet of human life which ‘one must know’ in order to grow and attain the summits of success. A team of around 200 dedicated members is working ceaselessly to turn such a colossal dream into reality. We are confident that this portal will help bring change in people across the world.
