Understanding ultrafine nanodiamond formation using nanostructured explosives

Understanding ultrafine nanodiamond formation using nanostructuredexplosivesA scientific team of the joint research unit NS3E (French GermanResearch Institute of Saint-Louis – French National Research Agency CNRS –University of Strasbourg). It describes the synthesis of nanodiamonds bythe detonation of nanostructured explosive charges thus obtainingnanodiamond particles of a size comprised between
1 and 3 nm.


Never beforea nanostructured charge has been detonated to produce diamondnanoparticles.Nanodiamonds can be used in multiple applications such as medical therapy(as kind of tracers), cryptography, optical protection, hardening of newmaterials etc.« Understanding ultrafine nanodiamond formation using nanostructuredexplosives » - this
is the title of an article published in “Nature –scientific reports”
by a scientific team of the joint research unit NS3E(ISL – French National Research Agency CNRS – University of Strasbourg).It describes the elaboration of a new technique for the synthesis ofnanodiamonds by the detonation of nanostructured explosive charges thusobtaining nanodiamond particles of a size comprised between 1 and 3 nm.This is the first time worldwide that such an experience has been made.Never before a nanostructured charge has been detonated to produce diamondnanoparticles. These research activities will also contribute to a betterunderstanding of detonation mechanisms on a local level.Nanodiamonds can be used in multiple applications such as medical therapy(as kind of tracers), cryptography, optical protection, hardening of newmaterials etc.Up to now, the synthesis of nanodiamonds has been realized by detonatingmicrostructured explosives, but this method only permitted the productionof extremely small quantities of nanodiamonds having a size of 1 to 3 nm.The passage from a microstructered charge to a nanostructured one thanksto a new proceeding of nanocristallisation - also developed by ISL andCNRS- allowed the NS3E team to synthesize finer nanodiamonds in biggerquantities.For more information please confer to the article published by NatureScientific Reports.
