Unusual types of gramophone records did have etched labels as well, with many (if not all) also featuring a little etched picture of Thomas Edison. The Gramophone company etched their logo at the blank side of their single sided records in the early 1900s, in the same way, Some later single sided Red Seal records by Victor had a pattern with the word Victor on it. After having already released both colored vinyl singles and picture discs in the 1980s, Canadian rock artist Bryan Adams issued a 12" single of "Can't Stop This Thing We Started" in autumn 1991, which had the front cover photography
Aluminum polymer composite Aluminum polymer composite An aluminum polymer composite (APC) material combines aluminum with a polymer to create materials with interesting characteristics. In 2014 researchers used a 3d laser printer to produce a polymer matrix. When coated with a 50-100 nanometer layer of aluminum oxide, the material was able to withstand loads of as much as 280 megapascals, stronger than any other known material whose density was less than , that of water. Spherical aluminum foam pieces bonded by polymers produced foams that were 80-95% metal. Such foams were test=manufactured on an automated assembly line and are under consideration as automobile parts.
