In cases where known dated writings are not available for comparison with questioned inks, accelerated aging (heating the ink to induce aging of the ink) can sometimes be used to estimate the age of ink using any or all of the above described techniques.Iron-based inks can be dated by measuring the migration of iron along the fibers of the paper by Scanning auger microscopy.Also, knowledge of the first production date for each type of ink or certain ingredients in the inks is useful for dating inks.In its simplist form carbon inks consist of amorphous carbon shaped into a solid cake with glue.The coated substrate is then blasted with single laser pulse.The end result is a film of Q-carbon‘We’ve now created a third solid phase of carbon,” said Jay Narayan, the John C.Written in ink in an early form of Arabic script on parchment made from animal skin, the pages contain parts of the Suras, or chapters, 18 to 20.” It noted that “several historians have said that the parchment might even predate Muahammad.” Reported historian Tom Holland, “It destabilizes, to put it mildly, the idea that we can know anything with certainty about how the Quran emerged – and that in turn has implications for the history of Muhammad…” Keith Small, from Oxford’s Bodleian Library, was blunt, “This gives more ground to what have been peripheral views of the Quran’s genesis, like that Muhammad and his early followers used a text that was already in existence and shaped it to fit their own political and theological agenda, rather than Muhammad receiving a revelation from heaven.” The report said the fragments were found inside another Quran.The documents were collected nearly a century ago by Alphonse Mingana, a priest who collected Middle East documents during expeditions sponsored by Edward Cadbury, a scion of the chocolate dynasty.

Q-carbon, which is the third solid phase of carbon, can be altered to produce real diamonds Scientists from North Carolina State University coated a substrate of sapphire, glass or a plastic polymer with a layer of non-crystalline amorphous carbon.By using different substrates and changing the duration of the laser pulse, how fast the carbon cools can also be controlled.When scientists want to create more diamonds with Q-carbon, they simply repeat the laser pulse and cooling process Q-carbon is actually harder than diamond.Diamond structures are created within the Q-carbon by changing the rate of cooling Sony SRS-XB40 has a built-in multi-coloured line light, speaker lights and a flashing strobe.It features 24 hours of battery life and claims to be a 'mini-disco on the move'.
