Sea water can be made drinkable? Francesca, S.S.P.G "Luigi Castiglione", Italy

Resim
 Sea water can be made drinkable by filtration with graphene. The latter is a material of considerable importance and is attracting the attention of many researchers, in fact it has extraordinary electrical and mechanical characteristics. This news is due to research by Andre Geim (Nobel Prize in Physics in 2010) and Konstantin Novoselov, who published their results in Nature Nanotechnology. Among the scientific curiosities proposed it is perhaps the most significant.

Alessandro C.- I.C. "Falcone_Cascino"-Italy-The atom

Resim
 The atom is the smallest fraction of an element capable of preserving its chemical and physical characteristics. Matter can have a property called electric charge; the latter can be of two forms,positive (+) and negative (-). Electric charges of the same sign repel each other, while charges of opposite sign attract each other. At the end of the nineteenth century it was discovered that atoms contain very small parts of cells with a negative electric charge, called electrons. But the atoms as a whole are neutral, that is, they have no electric charge: therefore they must also contain positive charges, which exactly compensate for the negative charges of the electrons. All positive charges are collected in a small volume in the center of the atoms, called the nucleus, around which electrons orbit. The nucleus of atom are made up of two types of particles: protons, each of which has a positive electric charge, and neutrons, which have no electric charge. The structure of the atom is ...

 importance of science: The knowledge that people acquire by experimenting and observing is called science. It is derived from the word know, meaning to leave a trace in memory. In order to have clear information in every field in the universe, science is definitely used. It can also be expressed as activities done to obtain information about the universe and everything in the universe. The purpose of science is to find the truth. It is the instinct of learning the cause of events, their benefits and harms, and their consequences, which has led the human mind to a continuous research and examination since ancient times. This research and study played a great role in the development of civilization. In particular, the facts revealed by the positive sciences as definite and unchangeable rules have been a light on the way for human beings to live more comfortably, more civilized and humanely.
