Transport phenomena is a research area concerned with the fundamental mechanisms and coupled behavior of momentum, heat, and mass transfer in physical, chemical, and biological systems. It formulates and analyzes balance equations derived from conservation laws, typically expressed as partial differential equations such as the Navier–Stokes, energy, and species transport equations. The field emphasizes constitutive relations (e.g., Newton’s law of viscosity, Fourier’s law of heat conduction, Fick’s law of diffusion) and dimensionless analysis to characterize regimes and scaling. Transport phenomena underpins modeling, simulation, and optimization across chemical engineering, materials processing, microfluidics, energy systems, and physiological flows.

Superconductors are materials that can conduct electricity with a resistance of zero. In so-called conventional superconductors, this occurs at low temperatures when electrons become bound into pairs, known as Cooper pairs.
