**Title:** Exploring Atoms with an Electron Microscope at IIT Roorkee
**Summary:**
* The host visits IIT Roorkee to showcase an electron microscope capable of magnifying objects up to 2 million times.
* A specially prepared gold sample, just 3mm in diameter and 30 nanometers thick, is loaded into the microscope.
* The process of creating a vacuum and using plasma cleaning is explained.
* The host explains the basics of the microscope's functionality, highlighting the use of magnetic lenses to focus electrons.
* As the magnification increases (up to 2 million times), the audience is shown:
1. Lines resembling fingerprints, revealed to be lines of atoms.
2. Individual atoms, appearing as dots, in a structured arrangement within the metal.
* The video concludes with the host reflecting on the uniqueness of the experience and encouraging viewers to subscribe for more content.
Here are the key facts extracted from the text, numbered and in short sentences:
1. **Sample Size**: The sample used is 3 millimeters in diameter.
2. **Sample Thickness**: The gold sample is 39 nanometers thick.
3.. **Thickness Comparison**: To put the thickness into perspective, a human hair cut into 80,000 sections would be similar.
4. **Sample Preparation Time**: Generally, it takes two days to prepare a sample for the electron microscope.
5. **Microscope Type**: The microscope used is referred to as the "India Microscope".
6. **Magnification Capability**: The microscope can magnify up to a million times.
7. **Electron Acceleration**: The machine accelerates electrons to 300,000 volts.
8. **Plasma Cleaner Usage**: A plasma cleaner is used to clean the sample before loading into the microscope.
9. **States of Matter**: Plasma is considered the fourth state of matter, beyond solid, liquid, and gas.
10. **Electron Control**: Electromagnets are used to control the charged electron particles.
11. **Lens Material**: Due to the nature of electrons, glass lenses are not used; instead, magnetic lenses are utilized.
12. **Zoom Scale**: The microscope's zoom scale starts at 10,000x and goes up to a million times magnification.
13. **Atomic Visualization**: At high magnification (e.g., 2 million x), individual atoms can be visually distinguished.
14. **Atomic Arrangement**: Atoms within metals are arranged in a structured pattern, not scattered randomly.
15. **Location of Experiment**: The experiment and demonstration took place at IIT Roorkee.
