Understanding ultrafine nanodiamond formation using nanostructured explosives

18.07.2013
A scientific team of the joint research unit NS3E (French German Research Institute of Saint-Louis – French National Research Agency CNRS – University of Strasbourg).

It describes the synthesis of nanodiamonds by the detonation of nanostructured explosive charges thus obtaining nanodiamond particles of a size comprised between 1 and 3 nm.Never before a nanostructured charge has been detonated to produce diamond nanoparticles.


1: nanostructured explosives
2: charge and detonation
3: nanodiamonds

Nanodiamonds can be used in multiple applications such as medical therapy (as kind of tracers), cryptography, optical protection, hardening of new materials etc.

« Understanding ultrafine nanodiamond formation using nanostructured explosives » - 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 of nanodiamonds by the detonation of nanostructured explosive charges thus obtaining 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 diamond nanoparticles. These research activities will also contribute to a better understanding 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 new materials etc.

Up to now, the synthesis of nanodiamonds has been realized by detonating microstructured explosives, but this method only permitted the production of extremely small quantities of nanodiamonds having a size of 1 to 3 nm. The passage from a microstructered charge to a nanostructured one thanks to a new proceeding of nanocristallisation - also developed by ISL and CNRS- allowed the NS3E team to synthesize finer nanodiamonds in bigger quantities.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
