The term “nanotechnology” is becoming increasingly prevalent, not just in scientific circles but also in the IELTS exam. Understanding this term and its related vocabulary is crucial for achieving a high score, especially in the Reading and Listening sections where scientific topics are common.
Here’s a breakdown of the word “nanotechnology”:
- Pronunciation: /ˌneɪnoʊˌtɛkˈnɒlədʒi/
- Part of speech: Noun
- Definition: The branch of technology that deals with dimensions and tolerances of less than 100 nanometers, especially the manipulation of individual atoms and molecules.
- Example: Nanotechnology has the potential to revolutionize fields like medicine and manufacturing.
Here are some synonyms and related terms you might encounter:
- Nanoscience: The study of extremely small things and their properties.
- Nanomaterials: Materials that are structured at the nanoscale.
- Atomic manipulation: The process of moving individual atoms.
- Molecular engineering: The design and creation of molecules with specific properties.
- Microscopic: Extremely small; visible only with a microscope (often used as a synonym for “tiny” or “minute”).
Understanding Nanotechnology
Nanotechnology delves into the fascinating realm of manipulating matter at the atomic and molecular level. It involves designing, building, and controlling materials and devices on an incredibly small scale, typically measured in nanometers (one billionth of a meter). To put this into perspective, a sheet of paper is about 100,000 nanometers thick.
