Pneumatic actuators are devices that convert the energy of compressed air or gas into a mechanical motion that regulates one or more final control elements. They are used as a form of automation control to reduce mandatory human interaction with a system's internal mechanisms, which is particularly beneficial for automatic modulation and emergency shutdowns.
The Popigai crater, located in central and eastern Siberia, Russia, is home to an astonishing diamond reserve—over ten times greater than all other known diamond deposits worldwide. In the early 1970s, due to political and economic constraints, the mine was effectively hidden from the world for more than three decades. However, recent scientific research has revealed extraordinary properties in the diamonds extracted from this site, surpassing both natural and synthetic diamonds in certain aspects.
Scientists from Siberia have discovered that these unique diamonds, dubbed "impact drills," possess remarkable abrasive qualities. According to Nikolai Pokhilenko of the Sobrev Institute of Geology and Mineralogy at the Siberian Branch of the Russian Academy of Sciences, these diamonds are up to 50% to 60% harder than synthetic ones. The term "impact drills" refers to their formation through meteorite impacts, which gave them a special structure ideal for polishing ultra-smooth surfaces—even nano-single-crystal diamond surfaces can be polished without any scratches.
These diamonds have attracted significant attention from researchers and industries alike. Their exceptional properties make them highly valuable for high-precision optical systems used in satellites, as well as in luxury jewelry. Additionally, they show great potential in industrial applications such as composite materials, drilling equipment, and cutting tools. Pokhilenko mentioned that Russia is collaborating with institutions like the Kiev Institute of Ultra Solid Materials, Almazy Anabara Diamonds, and Element Six to further explore the potential of these impact drills.
In 2014, the project will conduct further exploration of the Popigai crater, with the goal of collecting more impact drill samples near the crater's edge. Pokhilenko estimated that the total reserves of these unique diamonds could reach around 3 billion carats.
With the global demand for industrial diamonds growing rapidly—by 10% to 15% annually each year—these impact drills may soon challenge synthetic diamonds in the market. While synthetic production has reached 14 billion carats, the rare and superior qualities of these natural diamonds could position them as a leading choice in the future.
Formed approximately 35 million years ago when a space projectile collided with Earth, the Popigai crater spans 100 kilometers in diameter and is situated in the Arctic Circle, near Norilsk, Russia. This ancient impact site continues to surprise scientists with its incredible geological treasures.
