Quantum tunnelling
Quantum tunnelling (or tunneling) is the quantum-mechanical effect of transitioning through a classically-forbidden energy state. Consider rolling a ball up a hill. If the ball is not given enough ... > more -
Macromolecule
The literal definition of the term macromolecule implies large molecule. In the context of science and engineering, the term may be applied to conventional polymers and biopolymers (such as DNA) as ... > more -
Integrated circuit
A monolithic integrated circuit (IC) or often referred to as a microchip or simply chip is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive ... > more -
Wave-particle duality
In physics and chemistry, wave-particle duality holds that light and matter exhibit properties of both waves and of particles. A central concept of quantum mechanics, duality addresses the inadequacy ... > more -
Evaporation
Evaporation is one of the two forms of vaporization. It is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the ... > more -
Supercooling
Supercooling is the process of chilling a liquid below its freezing point, without it becoming solid. A liquid below its freezing point will crystallize in the presence of a seed crystal or nucleus ... > more
