Despite their name, nanodiamonds (ND) are comprised of a complex interplay of different
carbon phases. The diamond core is surrounded by the shell consisting mostly of disordered …

Nanocrystalline diamond (NCD) is a promising material due to its extraordinary properties,
such as ultrahigh strength and hardness. The effects of strain rate (ε˙) and annealing …

We report depth-resolved photoluminescence measurements of nitrogen-vacancy (NV−)
centers formed along the tracks of swift heavy ions (SHIs) in type Ib synthetic single crystal …

Nanoparticles are ubiquitous in nature and are increasingly important for technology. They
are subject to bombardment by ionizing radiation in a diverse range of environments. In …

Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility.
However, the exact role displayed by their grain structure in mechanical properties has not …

We studied by means of an atomistic model based on molecular dynamics the thermal
evolution of surface atoms in amorphous silica under high electronic excitation produced by …

In this contribution, we present a study of the mechanical properties of porous nanoshells
measured with a nanoindentation technique. Porous nanoshells with hollow designs can …

Hollow nanoparticle structures play a major role in nanotechnology and nanoscience since
their surface to volume ratio is significantly larger than that of filled ones. While porous …

By varying the CH 4 content of the mixed gas precursor of hot-filament chemical vapor
deposition, a group of nanocrystalline diamond (NCD) films was fabricated in a dual …

The existence of polycrystalline shells has been widely reported in the synthesis of hollow
nanoparticles; however, the exact role displayed by the grain boundaries on the stability has …
