The Nanoscale

Welcome to our lesson on understanding the nanoscale! In this video, we explore the fascinating world of particle sizes, focusing on how to categorise nanoparticles, fine particles, and coarse particles by their diameters. This involves learning about the measurement unit known as the nanometre, which equals one billionth of a metre. 📚 Here's what you will learn: How to use nanometres to measure incredibly small particles, much tinier than commonly used units like metres. How to identify and differentiate particles based on size, from nanoparticles (less than 100 nanometres) to fine particles (100 to 2,500 nanometres) and to coarse particles (2,500 to 10,000 nanometres). How these particles affect their environments: Discover why the size of nanoparticles makes them highly reactive and useful in fields like medicine and electronics. How fine particles, such as dust, impact health and air quality due to their ability to enter the respiratory system. How coarse particles, like pollen, interact with the body differently than smaller particles. ✨ Key topics covered: Measurement in nanometres: Gain insight into why and how we use this unit for particle size. Applications of nanoparticles: Explore their role in enhancing reactivity in various scientific fields. Environmental impact of fine and coarse particles: Understand the implications for health and air quality. 🤔 Common questions answered: How are nanoparticles, fine particles, and coarse particles measured? What is a nanometre and why is it important in measuring small particles? How do nanoparticles differ from larger particles in terms of properties and applications? What health effects are associated with fine particles? How do coarse particles such as pollen affect air quality and the respiratory system? Join us for this exciting exploration of particle science and discover how understanding these tiny entities can have a big impact on material science, environmental health, and technology!
