This paper intends to report three experimentally simple preparations of naphthoquinone, hydroquinone and the corresponding mixed quinhydrone,all redox chemistry being carried out in the solid state.
Fortunately, many modern devices use solid state electronics-non-moving semiconductors inside the machine which automatically convert the electrical current.

Further, unlike vacuum tubes made of glass and with carefully suspended, fragile components, transistors were solid material known as a solid state component.
