CWRU chemists developed a space-saving method to store digital data optically, using four-symbol, or quaternary code. The four symbols are the absence of color and three colors — fluorescent green, ultramarine and cyan — produced when dyes contained in a common polymer are exposed to heat, ultraviolet light or both.

Chemists at Case Western Reserve University have found a way to possibly store digital data in half the space current systems require. From supercomputers to smartphones, the amount of data people generate and collect continues to grow exponentially, and the need to store all that information grows with it. To reduce storage space, engineers have traditionally used existing technology but made it smaller...
