Diamonds are pretty darn tough. How tough? Tough enough that squeezing a couple of them together in a molecular diamond anvil — a technique that’s capable of achieving 100 times the pressure experienced at the bottom of the Mariana Trench — can be used to create custom molecules through the triggering of unique chemical reactions.
A little-reported event in Brisbane, Australia, in December has shifted the balance of power in the global diamonds industry and could lead to a greater voice for the African nations at the center of the multi-billion dollar trade.

Along with being a girl's best friend, diamonds also have remarkable properties that could make them ideal semiconductors. This is welcome news for electronics; semiconductors are needed to meet the rising demand for more efficient electronics that deliver and convert power.
Scientists at the US Department of Energy's Brookhaven National Laboratory have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond ― using bundled strands of DNA to build Tinkertoy-like tetrahedral cages,
These days Meighan wetland, a one-hundred-acre desert to the north of Arak, presents a beautiful view with the bright sun, coolness and purity adding to its beauty. Meighan Desert provides fresh air and water for the city of Arak, in Markazi province.
