To make artificial ivory they used a dimethacrylic resin in a liquid state, in which they embedded fine particles of calcium phosphate.
George Davis and William Watts, convicted for piracy for the Cyprus mutiny, were the final hangings at the dock on 16 December 1830.

(Courtesy: Technical University of Vienna) Claimed to be highly realistic and elephant-friendly, a new alternative to ivory has been developed by researchers in Austria. Led by Jürgen Stampfl at the Vienna University of Technology, the team used stereolithography to 3D print a replica material called “Digory”, which they claim closely mimics both the mechanical and optical properties of real ivory. Their approach could make it far easier for conservators to restore historical ivory artefacts. Renowned for its aesthetic appearance, durability, and ease of sculpting, ivory has been used for centuries to create practical and artistic objects. However, its use has extracted a terrible toll on elephant populations and its global trade was banned completely in 1989. Today, conservators use synthetic replica materials to restore damaged ivory artefacts – yet none of these are fully able to recreate characteristics like the colour, translucency, and surface gloss of the real thing. Stamfl’s team aimed to recreate these properties using stereolithography: a 3D printing technique that uses heated, light-sensitive resins to construct polymer materials layer by layer. Previously, the researchers used this approach to create ceramic materials, and even artificial teeth.

This is a compendium of the best-selling music singles. The criterion for inclusion is to sell at least ten million copies worldwide. The singles listed here were cited by reliable sources from various media, such as digital journalism, newspapers, magazines, and books. According to Guinness World Records, Irving Berlin's "White Christmas" (1942) as performed by Bing Crosby is the best-selling single worldwide, with estimated sales of over 50 million copies.[1] The song, recognized as "the best-selling single of all time", was released before the pop/rock singles-chart era and "was listed as the world's best-selling single in the first-ever Guinness Book of Records (published in 1955) and—remarkably—still retains the title more than 50 years later". Guinness World Records also states that double A-side charity single "Candle in the Wind 1997"/"Something About the Way You Look Tonight" (1997) by Elton John (rewritten as a tribute to Diana, Princess of Wales, rather than Marilyn Monroe in the original 1973 version), is "the biggest-selling single since UK and US singles charts began in the 1950s, having accumulated worldwide sales of 33 million copies". This makes it the second-best-selling physical single of all time.[1] Two best-selling singles lists are displayed here relating first to physical singles (mainly CD and vinyl singles) and second to digital singles (digitally downloaded tracks which first became available to purchase in the early 2000s).
