Diamond nanoparticles of ~5 nm in size offer a large accessible surface and tailorable surface chemistry. They have unique optical, mechanical and thermal properties and are non-toxic. The potential of nanodiamond in drug delivery has been demonstrated, fundamental mechanisms, thermodynamics and kinetics of drug adsorption on nanodiamond are ...
The structure and particle size of the obtained diamond is rather similar to that obtained in explosion. In particular, many particles exhibit multiple twinning. [6] A research group from Case Western Reserve University produced nanodiamonds 2–5 nm in size at near-ambient conditions by a microplasma process. [7]
[5] [6] The material is a series of interconnected diamond nanorods, with diameters of between 5 and 20 nanometres and lengths of around 1 micrometre each. [citation needed] Nanodiamond aggregates ca. 1 mm in size also form in nature, from graphite upon meteoritic impact, such as that of the Popigai impact structure in Siberia, Russia. [1]
Due to their well-defined size and structure diamondoids also serve as a model system for electronic structure calculations. [ 9 ] Many of the optoelectronic properties of diamondoids are determined by the difference in the nature of the highest occupied and lowest unoccupied molecular orbitals : the former is a bulk state , whereas the latter ...

Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.
Bryan cried for help. It was the middle of the day on Friday, June 10, 2005. His third-floor apartment was on W. Diamond Street in Philadelphia, in a red brick building next door to his fraternity. Two friends were in the room with him. In an instant, Bryan and the man with the gun started to struggle, falling to the hardwood floor.
