Polymers and Plastics: Structure, Production and Environmental Effects

 Raw polymer is the general term for various types of polymeric materials, and therefore, it does not have a single formula. Instead, a specific formula is needed for a particular type of raw polymer. For example, the chemical formula for a type of raw polymer called polyethylene (PE) is as follows: \[ (CH_2CH_2)_n \] Here, \( n \) represents the number of repeating ethylene monomers in the polymer chain. Therefore, the molecular structure of polyethylene consists of repeated CH2CH2 monomers polymerized in a chain. How are polymers made? Polymers are made by the coming together of small molecules called monomers to form long, chain-like polymer molecules. This process is called polymerization, and there are two types: 1. Solid-State Polymerization: In this method, monomers react to form polymer chains using temperature, pressure, and/or solvent. This method is slower and more expensive. 2. Solution Polymerization: Monomers dissolve in a solvent, and an initiator agent (usually a peroxi

Learn, Shape Your Future: Science's Opportunities – Natural Sciences, Social Sciences, Modern Applications

Science is a systematic set of methods used to understand, explain, and predict nature and the universe. It gathers knowledge through methods such as observation, experimentation, hypothesis formation, and testing, expressing this information through theories and laws. The primary goal of science is to expand knowledge about nature and the universe, enabling people to enhance their lives through technology and applications. Science can be broadly categorized into two main branches: natural sciences and social sciences. Some significant branches include: Natural Sciences: 1. Physics 2. Chemistry 3. Biology 4. Astronomy 5. Geology 6. Meteorology 7. Oceanography Social Sciences: 1. Psychology 2. Sociology 3. Anthropology 4. Economics 5. Political Science 6. History 7. Geography 8. Law 9. Communication Sciences Throughout human history, significant discoveries and inventions have been made in the pursuit of understanding the workings of nature and the universe. From ancient times, scientis

Key Things to Know Before Investing in $Crypto

  If you're considering investing in a project, don't rely on hearsay; instead, research the project and examine Coingecko data first. 1. What is its rank there? 2. What is the maximum supply? (Crucial) 3. What is the circulating supply? (Crucial) 4. What is the significance of the project? 5. If the maximum supply is unlimited, it could be problematic. 6. Eight signs of a flop indicate an unlimited supply. Some coins have a max supply of 10 billion with a circulating supply of 200 million. This is crucial because, no matter how important the project is, a token or coin can only rise so far or stay in place. It may not provide long-term gains. Some projects have an unlimited supply but still thrive, depending on how much the team releases into the market. For instance, XRP has remained stagnant for years due to its low circulating supply and high max supply. However, tokens with a narrow gap between circulating and max supply don't necessarily skyrocket; the project's s
