When it comes to rice, everyone must be familiar with it. Rice can be said to be a necessity for people to live. Because rice can be made into rice, we say we must eat it every day. After the rice is peeled out of the middle, the remaining husk is useless. Many farmers will choose to burn these husks, but because burning will produce thick smoke and affect the ecological environment, the current rice husks will be buried directly in the ground to corrode into nutrients for the next rice crop.
However, a scientist discovered a new use for rice. He will carry the rice. Over acid treated and then burned. Extract silica and add magnesium powder to make porous silicon powder. We all know that silica can be made into LED lights, and this porous silicon powder can make LED lights with higher intensity than ordinary ones. This discovery turned rotten and useless rice into magic and made it into LED lights that serve people. It can be said to be a very significant achievement and discovery. This discovery will further develop people's use of LED lights. It can be regarded as a breakthrough of great significance.
We all know about silica before it was extracted in this discovery. They are all extracted from quartz ore. The cost of silica is very high. And it’s not just about cost, either. The extraction of ores will have a greater or lesser impact on the earth's surface. If we could now extract a large amount of silica from unused rice husks and make such porous silica powder. Then it will not only improve people's living conditions, but also play a certain role in protecting the environment. This can also be regarded as protecting ourselves.
In our lives, this kind of discarded rice can also be reused, which shows that other things around us are not really useless. It's just that we haven't discovered what we need from these useless things. Just like the garbage in daily life, other useful things can be made after recycling. I believe that the things around us that cannot be recycled actually have certain uses. It's just that no one can find something from it that can help in life. I believe that more such things will be reused in the near future. Let us look forward to it together.
