The formula for transparent aluminum

Transparent aluminum was a construction material far stronger and much lighter than its predecessor, plexiglass. A one-inch thick sheet of transparent aluminum, measuring 60 feet × 10 feet, was capable of withstanding the pressure of 18,000 cubic feet of water, which could be used in place of a six-inch thick sheet of plexiglass.

Dr. Nichols, of the San Francisco-based Plexicorp, acquired the formula for transparent aluminum in 1986 from a mysterious engineer from Edinburgh, known as "Professor Scott." In exchange for the formula, Dr. Nichols provided enough Plexiglas to "Professor Scott" to construct a giant whale-tank in the cargo hold of the stolen Klingon Bird-of-Prey.

According to an early draft of Star Trek IV, transparent aluminum was invented in the mid-2130s. The novelization (likely based on a later draft) indicates that Dr. Nichols is the credited inventor of the formula – Scott concludes that his being in San Francisco and needing transparent aluminum when this "breakthrough" occurs is a predestination paradox.
The diagram Scott prepared seems to suggest it is made of hydrogen, silver, and aluminum.

The viewports of the USS Enterprise-D were made of transparent aluminum. In 2367 when an anomaly caused atmospheric decompression in the observation lounge, Data scanned the transparent aluminum in the windows, and found a pattern of transient electrical currents characteristic of subspace distortion.
