Material Design (codenamed Quantum Paper) [4] is a design language developed by Google in 2014. Expanding on the "cards" that debuted in Google Now , Material Design uses more grid-based layouts, responsive animations and transitions, padding, and depth effects such as lighting and shadows.
The table below shows some of the parameters of common superconductors.X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla.
