Materials Make Better Lives

Materials are used to make useful things. History has proved that the problem is the foundation of social progress and pilot and milestone in human progress. In ancient times, the use of different materials such as stone age and bronze age decided the development of civilization. In modern society, the development of steel materials played a decisive role in the industrial revolution. The development of semiconductor materials brought humanity into the digital age.

Today, new materials have the potential to change the future. Graphene known as "Super Material" is confused by researchers around the world to better understand it. A long list of materials with the most advanced quality makes it almost magical, but it can make a very realistic and strong impact on the future of physics and engineering. The easiest way to explain graphene is a thin sheet of graphite, a sheet of soft material used for the core of a pencil. Graphite is an allotrope of elemental carbon and means having the same atoms, but they are arranged in different ways and give the material different properties. For example, both diamond and graphite are in the form of carbon, but they have different properties. Diamond is very strong and graphite is very brittle. The atoms of graphene are arranged in a hexagonal arrangement

The properties of the material have a major influence on the determination of the materials used. Different materials have different strengths and in some cases are more suitable. The properties considered are strength, elasticity, porosity and water absorption, heat and moisture movement, thermal conductivity and electrical conductivity / resistivity, heat transfer, durability, processability, density, specific heat capacity and viscosity . Porosity is the number of cavitation or pores in the material. The density of the material is closely related to the porosity. As the material per unit volume increases, the pores in it decrease. The porosity of the material was tested by weighing the material, then leaving the material in water for a period of time and reweighing the material. This will provide a measure of the amount of water absorbed by the material and it can be displayed as a percentage

Plastics are high performance and versatile materials and are characteristic of modern industrial economy. As a symbol of the improvement of living standards and family happiness in the 1950s, this material is increasingly criticized as the production volume increases and the problematic waste increases. The biggest problem now is to know the undeniable function of the polymer and how to adjust the system that can be used for a long time. Avoid loss of material value and adverse effects. Banned Francisco and banned in parts of Africa and Asia. Can I take plastic ban? Of course, for the government, excessive use of plastic is a prudent approach, but ongoing attention to reduction causes several problems. Plastics have unique characteristics indispensable for many applications today.
