In last a few decades, there has been discovery and synthesis of a new class of materials that has astonishing properties but that could not be fully explained by the laws of classical physics. These properties can only be explained by quantum mechanics.

Quantum confinement effect: controlled dance of electrons at microscopic level
Every solid material is made up of atoms and atoms have electrons. The arrangement of electrons in a material determines the properties of the material. In bulk materials (when the size of the material is big enough, let’s say more than 100 nm), the electrons are free to move in all the three dimensions (similar to us, as we also live in 3D) and at this level classical physics can explain all the behaviour of the materials. However, if we reduce the size of the material to microscopic scale, where electron movement is restricted at least in once dimension, the properties of the material change dramatically
The Nobel Prize in Chemistry 2023 to Quantum dots!!
The Nobel Prize in Chemistry 2023 has been awarded to three scientists from USA for the discovery and synthesis of quantum dots.
